thanx cool post

WHAT U NEED:
==========

- A PSP with a Custom Firmware such as OE, M33 or WC, or a PSP with
the 1.5 original kernel. (To make the necessary Files and Convert the Battery into a Pandora's Battery.)

- A spare Memory Stick Pro Duo is not required. (1 is fine.)

- A spare Battery Is not required.
If U have 1 working Homebrew ready PSP.
And U are Unbricking/Downgrading Or Flashing another.

But U do need a second 1 if U wana be able to Unbrick your PSP if U only have 1.
Because U will not be able to make the necessary files later without a working PSP.
================================================== =

And this Works on Sony, Sandisk and Lexar Memory Stick PRO DOU's Just in case U guys are wondering.
================================================== =================

CHANGING YOUR BATTERY BACK TO NORMAL MODE:
To change it back just disconnect the battery from PSP connect the AC adapter and power on the PSP.
Then put the battery back in and run the Pandora's Battery Creator and press [ ] to change battery back to normal. Thats it.
================================================== ==============================

Step 1: Download Pandora's Battery from 1 of the Links above.
Extract the pandora.zip files.

Step 2: Insert the memory stick that you want to turn into a "magic memory stick." Back up the contents of the stick to your computer.

Step 3: Use the built-in format tool (in the PSP System Settings menu) to reformat your memory stick.

Step 4: Connect your PSP in USB mode.

Step 5: Open a command prompt (Start -> Run -> cmd)

Step 6: In the command prompt, switch into the 'mspformat' folder you extracted in step 1... wherever you put it.

Step 7: Type cd c:\
then "mspformat X" where X is the drive of your PSP. Do not include the colon. For example, my PSP is connected at O:, so I type "mspformat O".

You should see a prompt like this:

>>> C:\>mspformat.exe O
>>> You are about to format the drive O.
>>> All data will be lost. Do you want to continue? [Y]

Type 'y'.

>>> y

and you should see

>>> Drive succesfully formatted, and partition moved.

Step 8: Disconnect from USB mode, then remove and re-insert your memory stick. Reconnect in USB mode.

Step 9: On your memory stick, make sure that you have folders named GAME and GAME150 in a folder named PSP. If you don't have them, make them.

Step 10: Copy the two folders from 'battery' into GAME (for 1.50) or GAME150 (for custom firmware). The folders should be named "pandora_battery" and "pandora_battery%", so they should be \PSP\GAME\pandora_battery and \PSP\GAME\pandora_battery% (or \PSP\GAME150\pandora_battery and \PSP\GAME150\pandora_battery%).

Step 11: Disconnect from USB mode, insert the battery you wish to use as your unbricker, and run "Pandora's Battery Creator" from the Memory Stick section of the GAME menu.

Step 12: ***OPTIONAL - SEE NOTE *** Press Triangle to back up the contents of your battery's flash into a file on you memory stick. The program will automatically exit. Run "Pandora's Battery Creator" one more time. *Note:* This step is REQUIRED if you want to make this a normal battery again; otherwise it's optional.

Step 13: Press X to turn your battery into an unbricking battery (a Service Mode battery). The program will automatically exit.

Step 14: Connect in USB mode.

Step 15: Download the 1.50 EBOOT here http://www.sendspace.com/file/s2a2qo and Copy the 1.50 EBOOT file onto the root of your memory stick; it should be the same place as your "PSP" folder. Rename it to "UPDATE.PBP".

Step 16: The extracted folder "installer" contains two folders. Copy both of these into the same place you copied "pandora_battery".

Step 17: Disconnect from USB mode and run "Pandora's Battery Firm. Installer" from the Memory Stick section of the GAME menu.

Step 18: Press X to unpack the 1.50 firmware files into their proper place on your memory stick. The program will automatically exit. If this step fails, go back into USB mode and rename "UPDATE.PBP" to just "UPDATE", then try again.

Step 19: Connect in USB mode. Look in the root of your memory stick (where you have the PSP folder and the UPDATE.PBP file). There should be a file named "msipl.bin".

Step 20: Copy "msipl.bin" and "msinst.exe" to Drive C:\.

Step 21: In the Command Prompt, switch into the "msinst" folder... wherever you put it.

Step 22: Type "msinst X msipl.bin" where X is the drive of your PSP. Do not include the colon. For example, my PSP is connected at O:, so I type "msinst O msipl.bin".

You should see a prompt like this. I guarantee that your stuff will be slightly different; it depends on how your computer is set up, what sort of memory stick you have, and so on. As long as you get the "Are You Sure? [Y]" prompt, you know that the msipl.bin file is OK.

>>> C:\msinst O msipl.bin
>>> PSP MS IPL Installer
>>> Load IPL code msipl.bin
>>> 241664 bytes(59 block) readed
>>>
>>> Target DRIVE is 7
>>> Check partation Sector
>>> boot status 0x80
>>> start head 0x05
>>> start sec/cyl 0x0004
>>> partation type 0x06
>>> last head 0x0F
>>> last sec/cyl 0xB7E0
>>> abs sector 0x00000810
>>> ttl sector 0x000767F0
>>> signature 0xAA55
>>> Check BPB Sector
>>> signature AA55
>>> Check free reserved sector:OK
>>> Write ABS Sector 0x10 to 0x1E7
>>> Are You Sure ?[Y]

Type 'y'.

>>> y

and you should see

>>> Write MS BOOT CODE

That means that you now have a "magic" memory stick.

You're all set!

To unbrick a bricked PSP (this part's a lot easier, I promise):

1. Insert the "magic" memory stick.
2. Insert the unbricker battery. Your wifi, memory stick, and power lights should all turn on temporarily, and a menu should appear.
3. Press X. After it checks the update file, you should get another menu.
4. Press X to write Firmware 1.50 onto the PSP.

That's it... just let it work!

Now, you have a battery/memory stick pair that CAN UNBRICK ANY PSP just insert them into any PSP and it will be reinstalled with the v1.5 firmware.

With this ALL PS1 games work on 3.52M33-4 - 3.71M33 Firmwares.

Instructions: copy seplugins to the root of the memory stick:
http://www.sendspace.com/file/b107vh


Activate the plugin in recovery and done! First time you run a game, it will let you choose pops version.
Next time will remember configuration for each game press R to change it.
================================================== =========================



This can be helpful in many ways. Mainly to downsize the size of the homebrew.
With this Counter Strike went from 72mb to 32mb using CSO.

Heres the tutorial:

To start you should know the ISO directory unless you download the dummy iso i uploaded.
\PSP_GAME\ICON0.PNG
\PSP_GAME\PARAM.SFO
\PSP_GAME\PIC1.PNG
\PSP_GAME\USRdIR\
\PSP_GAME\SYSDIR\BOOT.BIN
\PSP_GAME\SYSDIR\EBOOT.BIN
\UMD_DATA.BIN

1) you will need PBP_Unpack.exe, PsPBrew.exe ,and UMDGen.
2) Instal Them if you didnt do so
3) Get your Favorite Homebrew you want to conver into ISO
4) if the home brew is in XKploite Form convert it using PsPbrew into 1.0 version
5) after doing so open EBOOT.PBP with PBP_Unpaker
6) extract data.psp
7) after that all you need to do is make two copys of that file
Cool rename 1 of thoughs files to BOOT.BIN and the other to EBOOT.BIN
9) after doing that place both of thoughs files in SYSDIR dir IN UMD Structure
10) if the homebrew your trying load has other files in there directory you caN PLACE THEM
in SYSDIR two.
11) after placing every file in the right directory
12) Just Use UMD Gen to make a PSP COmpatable ISO.
13) then your done.
================================================== =======

To do this just make a game150.txt in the seplugins folder and put the line of any PRX.
Example:
ms0:/seplugins/capture.prx in the game150.txt

And U will be able to use the PRX's while using homebrew.
======================================


1st U need to update to 2.71 if your on any other firmware below that.
(If U are above 2.71 Use another Downgrader.)

Here is the 2.71 Update:
http://www.sendspace.com/file/ahsadb

(MAKE SURE U PLUG IN YOUR PSP CHARGHER!)
(THE PSP BATTERY NEEDS TO BE AT 75% OR MORE FOR THE UPDATE TO RUN!)
So if your battery is lower then that then let it charge until it's at 75%.
Then Just put the EBOOT.PBP in the PSP/GAME/UPDATE and run it from the Memory Stick under GAME.

2.71 Updateflasher.rar:
http://www.sendspace.com/file/j7z9e6

U will also need:
=1.50 EBOOT=
http://www.sendspace.com/file/s2a2qo

And follow these steps:

1 - Copy all contents inside 2.71 Updateflasher to the root of your memory stick.
2 - Copy the 1.50 EBOOT WITH THE NAME (UPDATE.PBP) to PSP\GAME\UPDATE\
3 - Go to the PHOTO viewer of the XMB and enter in the folder "HENB".
- If the psp just freeze, reboot your psp and try again.
- The first time you run the program, you will see quickly a blue screen, and after that a screen
that can be of two colors:

* Red: the files couldn't be written to the flash (it hapens a few times). Just keep trying.
* Green: The files were written succesfully. After that, the xmb will be rebooted.

4 - On the PSP go to:

Settings-->
System Settings-->
System Information-->
U will see 2.71HEN
IF U do U are set for the last step.

5 - Now you can run the X.YZ Update to flash your PSP to 1.50.

DONE! ;)
================================================




This is an application to downgrade a ta-082 unit running 2.71 firmware and HEN-D to 1.50.

1.) - Extract 3.03 Downgrader.rar

2.) - Copy the PSP Folder to MS.

3.) - Load GTA LCS
- It should get to loading savegame, then the screen will clear to black
and fill with a light blue colour, then the PSP will reset itself (if
this does not happen see section below)

- If the PSP freezes try again
- When you run the program, you'll see a coloured screen that can be one of two colors:
* Red: the files couldn't be written to the flash (it happens a few times). Just keep trying.
* Pale Blue: The files were written succesfully, and HEN is active. After that, the xmb will be rebooted.

4.) - Check that HEN is running by going to system settings, then to
"System Information" and it should show up as system version
303 HEN

5.) - If it is showing up as HEN then go to the memory stick and
run the x.yz update

6.) - If you have an unpatched TA-082 or higher motherboard, you will be
prompted to allow the downgrader to patch your motherboard so it
can be safely downgraded. The downgrader will not let you proceed
without patching, if your motherboard requires it.

7.) - Before the downgrader does anything to your PSP it will ask
for you to agree to what it is doing, if you no longer want to
continue press the Right Shoulder Button (R-TRIGGER).

8.) - Once you have agreed to start the downgrade do not unplug the
PSP, or try and restart it

9.) - Once finished the PSP will ask you to press X, and reset itself

DONE!

I have version 4.01 where do i go from there???

7. Connect your PSP to your computer using a USB cable and activate the USB connection.
8. The program will auto-detect the memory stick and will ask 'Are you sure? [Y]', press Y.

If you have multiple memory sticks and want to write the boot code to another memory stick:
Close the USB connection on the PSP, insert the new memory stick and repeat step 6 to 8.

9. Close the black MSDOS window as you are finished installing the xmbloader bootcode.

After the bootcode has been installed to the memory stick, you can delete the 'xmbloader' folder from your 'Local Disk (C:)'



Converting your 'Battery' into a 'Pandora Battery'
If you already have a Pandora battery then you can skip this section, no need to make one when you already have one ;)

Note: If you get a game cannot be started error then make sure you are using a custom firmware PSP to make the battery.
An Official firmware PSP cannot run the battery creator program!

If you do have custom firmware, check the 'game folder homebrew' in recovery mode
is set to '3.xx kernel' and you are running the correct battery creator for your PSP firmware version (1.50 or 3.xx)


1. Insert the Pandora Memory Stick and the Battery you want to convert into a Pandora battery into your PSP and turn your PSP on.

2. Go to the 'Game -> Memory Stick' menu and:

-=> If you have a PSP with a Custom Firmware: (e.g 3.xx OE / 3.52 M33 / 3.71 M33 / 3.80 M33):

a. Start the 'OS Pandora Battery Tool 0.5'
b. When the program starts, Press the 'X' button to continue.
c. Choose the "backup battery eeprom to ms0:/eeprom.bin and press 'X'
d. Press 'X' again after the program has finished reading the battery data.

e. Choose the "convert to service mode (aka: pandora battery)"
f. Press 'X' again after the program has verified the battery serial is correct.
(If your battery serial doesn't change then the battery doesn't have a
writable EEPROM inside it so the Battery cannot be used as a Pandora Battery)

g. Choose 'quit now' and the program will exit.


-=> If you have a PSP with Official Firmware 1.50:

a. Start the 'Pandora's Battery Creator' program.
b. When the program starts, Press the 'Triangle' button to save your battery information to the memory stick.
c. The program will now exit to the XMB Menu.

d. Go back to the Game -> Memory Stick menu and start the 'Pandora's Battery Creator' Program again.
e. This time when the program starts, press 'X' to 'Convert your Battery into a Service Mode One'
f. The Program will now exit back to the XMB menu.

3. Your Battery has now been converted to a 'Pandora Battery'

4. Make a copy of the 'eeprom.bin' file from your memory stick to a folder on your computer as a backup.
(This file contains the 'Original' battery information, you will need this file to restore the battery back to an original one)


Making a 'backup' of your PSP NAND memory
What is the 'NAND'?
The NAND is the 'chip' the PSP stores all its data on (Partition Tables, IPL, Idstorage, Flash0 through to Flash3)
There is currently no way to 're-generate' the Idstorage area on a PSP system.
Making a Nand-dump of this entire chip will help if you need to fix a corrupted IdStorage, Flash0 etc.

Warning: Only use a NAND Dump on the PSP it was created on.

1. Turn off your PSP by holding the power button for 4 seconds.
2. Insert the 'Pandora Memory Stick' into your PSP, this must be done before you insert the battery.
3. Hold the 'L' button and insert the 'Pandora Battery' and your PSP will turn itself on automatically.

4. After a few seconds, you will see the 'Pandora`s Battery Recovery Menu' and will have 4 options.
5. Press the 'Square' button twice to start the 'NAND Dumper'

6. On the first screen you will see the size of the 'Nand' inside your PSP.
You will see 32MiB for an the Original PSP or 64MiB on the Slim PSP.

Your memory stick will require either 33mb (Original) or 66mb (Slim) of free space to make a NAND Dump.
If you have a 64mb memory stick, then you will not be able to do a Nand-Dump due to the lack of space on the memory stick

7. Press 'O' to move onto the next screen.
8. Choose 'Dump from NAND' option and press 'X'
9. The filename will be shown on the screen, Press 'X'

10. Wait while the PSP reads the NAND from your PSP and copies it to your Memory stick.
11. After the dump has completed, press 'X'
12. Press 'O' twice to return to the main menu.

13. Select 'Shutdown' and press 'X' and your PSP will turn off.

14. Make a copy of the NAND to your computer and keep it safe.
(you can use this to restore your PSP if something goes wrong)


Downgrade / Unbrick a PSP using the Pandora Battery and Memory Stick

Before Installing Custom firmware onto a PSP, I recommend to make a 'Nand-Dump' just in case something goes wrong.
You can use it to 'revert' your PSP back to how it was before you attempted to install custom firmware on it.

1. Turn off your PSP by holding the power button for 4 seconds.
2. Insert the 'Pandora Memory Stick' into your PSP, this must be done before you insert the battery.
3. Hold the 'L' button and insert the 'Pandora Battery' and your PSP will turn itself on automatically.

4. Afer a few seconds, you will see the 'Pandora`s Battery Recovery Menu' and will have 4 options.

X = Will Install custom firmware onto your PSP.
O = Will Install official firmware onto your PSP (this is useful if you need to send PSP back for repair)
[] = Will start 'Nand-tool' so you can make a backup of your PSP flash memory.
L+R+Start+Home = Restore a nand-dump (Use Nand-Tool to restore the nand-dump instead)

5. Press 'X' to start the install of the custom firmware. While the firmware is installing, the memory stick and WiFi lights will flash, this is normal.

6. Once the 'Custom Firmware' install has completed, the Memory Stick and WiFi lights will stop flashing and you will be asked to restart the PSP.

7. Turn off your PSP and turn it back on.
Note: If you upgraded a Slim PSP and the psp won't turn on, change the Pandora battery to a slim battery.

• If you get a 'Corrupted Settings' blue screen error message:
  Press 'O' a few times and your PSP should restart with fixed settings.
  The PSP will then go through the 'Initial Setup' process, (setting time / date / name etc.)
• If your PSP freezes before it loads the XMB menu:
  Turn off your PSP (hold the power button up for 7 seconds).
  Turn on the PSP holding the 'R' button to access 'Recovery mode'
  Select the 'Advanced' Menu and press 'X', select the 'Format Flash1 and Reset Settings' option and press 'X'
  The PSP will then go through the 'Initial Setup' process. (setting time / date / name etc.)
• If your PSP loads the XMB menu:
  Go to the 'Settings Menu' and redo the settings (Nickname / Video Settings, Theme Settings etc)
  (Or you can use the 'Reset to default settings' option on the Settings -> System Settings menu)

9. Turn off the PSP by holding the power switch for 4 seconds.
10. Hold the 'R' Button and turn the PSP back on to enter recovery mode and configure the recovery mode options.

Recovery mode Configuration options.

11. After you have set the Recovery Mode options, choose "Exit" to go back to the XMB menu.


Restore a Pandora Battery back to a Normal Battery

1. Insert the Pandora Battery and Pandora Memory stick into your PSP. (Your PSP will turn itself on automatically)

2. Go to the 'Game -> Memory Stick' menu and:

-=> If you are using a PSP that has 'custom firmware' (e.g 3.71 M33 / 3.80 M33 / 3.90 M33):

a. Start the 'OS Pandora Battery Tool 0.5'
b. When the program starts, Press the 'X' button to continue.
c. Choose the 'Flash only serial from ms0:/eeprom.bin' option.
(note: If you don't have a eeprom backup, choose the 'convert to normal mode' option)

d. Press 'X' again after the program has finished writing the battery data.
e. Choose 'quit now' and the program will exit.


-=> If you are using a PSP with official firmware 1.50:

a. Start the 'Pandora's Battery Creator' program.
b. When the program starts, Press the L and R buttons at the same time.
This will flash the battery eeprom from ms0:\eeprom.bin.
(note: If you don't have a eeprom backup, choose the 'convert battery in normal one' option)

c. The program will now exit to the XMB Menu.

3. Your Pandora Battery has now been converted back to a 'Normal Battery'



Restore a Pandora Memory Stick back to a Normal Memory Stick

/!\ Warning: /!\
Make sure you have restored your battery back to normal. If you do this first you may not be able to change
the 'Pandora Battery' back to a 'Normal Battery' since the 'Battery eeprom' information is stored in a file on the memory stick.

Formatting your memory stick will delete everything from it, Check that you have no important files on your memory stick before doing this.
If you have important files on the memory stick, make a copy of them to your computer before formatting your memory stick.

1. Insert a battery into your PSP and turn it on.
2. Insert the Pandora memory stick that you want to change back to a normal memory stick.
3. Go to the 'Settings Menu' and choose 'System Settings'
4. Choose the 'Format Memory Stick' option and choose 'Yes' and 'Yes' again
5. Once the memory stick has been formatted is it back to normal.


How To Recharge the Pandora Battery

1. Insert the 'Pandora Battery' and hold the 'L' button to access Pandora recovery menu.
2. Hold the power button up for 7 seconds to turn off the PSP.
3. Plug in your battery charger / AC Adaptor.
4. The battery light should turn Orange to indicate that the battery is charging.
5. Turn off your PSP by holding the power button for 4 seconds.
6. The power light should still be orange after the PSP power is off.
7. Once the battery is fully recharged, The orange power light will turn off.


Fixing your PSP Flash Memory Partition Tables

If your PSP freezes at a 'formatting flash' when trying to use pandora, your PSP may have a 'corrupted partition table'.
If you have a Nand-dump, then you should restore it WITHOUT the 'Idstorage' option.
If you don't have a Nand-dump, you can use a 'lflash format' to try and repair the partition tables.

NandTool 0.3b1:
Download: http://www.sendspace.com/file/lopm79
Mirror : http://www.zshare.net/download/56809643bd8998/

Installing Nand-tool
(Most users can skip these steps as I've included 'Nand-tool' as a part of the Pandora Install Files)
1. Download 'NandTool 0.3b1' and extract it to a folder on your computer, you will get a file called 'backup.elf'
2. Insert your 'Pandora Memory Stick' into your PSP and connect it to your computer (or use a memory stick card reader)
3. Copy the 'backup.elf' file and paste it inside the "KD" folder and overwrite the existing file.
4. Close the USB connection and disconnect the USB Cable. (or take memory stick out of the card reader)

Instructions on Using NAND-Tool:
5. Make sure you have at least 33mb of 'free space' on your memory stick' for a original PSP, or 66mb for a slim PSP.
6. Insert 'Pandora Memory Stick' into your PSP
7. Insert 'Pandora Battery' into your PSP while holding the 'L' button to access 'Pandora Recovery Menu'.
8. Wait for 5 seconds and then press the 'Square' button to start the 'NAND Dumper' program.

9. On the next screen, press 'O' to go to the next part of the dumper.
10. Choose 'Dump from NAND' option and press 'X',
You will see the filename the 'NAND Image' will be copied to, press 'X' again.
* Please wait while your PSP NAND is being copied to your memory stick *

11. Once the dump is completed press 'X', now press 'O' to go back to the main menu.
12. Select the 'Other' menu option and press 'X'
13. Select the 'Repartition lflash' option and press 'X'
14. Press 'Triangle' to confirm you want to 'logically format the flash'
* Wait while the lflash area is logically formatted, this may take a few minutes *

15. After the lflash format has been completed, press 'X'
16. Press 'O' to go back to the main menu.
17. Scroll down to 'Quit' and press 'X', the PSP will shut down.
18. Hold 'L' and turn the PSP back on and you will see the 'Pandora Recovery Menu'
19. Press 'X' to install 'Custom firmware M33' and custom firmware will be installed.

After the custom firmware install has finished, your PSP should hopefully be working properly.
I recommend you delete the old non-working NAND-dump and make another backup of your working PSP using 'NandTool'.
If the 'lflash' gets corrupted again, you can restore the dump instead of repartitioning and installing the custom firmware again.

4. Close the USB connection on your PSP (press 'O') and unplug the USB cable from your computer and your PSP.

5. Turn off your PSP by holding the power button for 4 seconds then turn it back on.
(This will give your PSP a 'clean boot' so 'HEN' will have a better chance of loading in step 6.)

6. In the XMB of your PSP go to the Photo menu then open the HEND folder.

Note: It may take a few tries to get HEND to load, the TIFF exploit doesn't load all the time.
If you have a 'custom wallpaper', try setting one as it may increase the chances of HEND loading.
See the 'Customize your PSPs Background Picture section for instructions on setting a custom wallpaper.
If your PSP freezes, restart your PSP and try loading HEND again.

If HEND successfully loaded, you will see a blue screen and then either:
Red: The files couldn't be written to the flash, you will need to keep trying as it doesn't work all the time...
Green: The files were written successfully, The PSP will restart and you can go to the next step.

If you want to check if HEND is loaded, check your 'system firmware version', it should read 2.71-HEND if HEND is loaded.

7. Run the 'TA-082_86_Enabler' from the game > memory stick menu if you have a TA-082 /TA-086 PSP.
The program will detect if your PSP is a TA-082 or TA-086 and will patch it to run 1.50 if its needed.
If you are sure that your PSP is definitely a TA-079 then you won't need to run this and can skip to the next step.
If you are unsure, check the top of the post, under the 'Checking your PSP Motherboard Model' section

Note: If you have a TA-082 or TA-086 and don't run the 'Enabler' then you will brick your PSP when downgrading in step 8.

8. Run the 'PSP Update ver X.YZ' from 'Game' > 'Memory Stick' to start the downgrader.
9. The rest of the steps are pretty simple, follow the on-screen instructions.

10. When you turn your PSP back on you will get a corrupt settings error with a blue background.
Just press the "O" button and your PSP will restart with repaired settings.
your PSP should then go through the setup process again. (set date / time etc)

If the psp screen stays black when you turn on your PSP,
Try pressing the 'screen brightness' button near the start / select buttons.
For some unknown reason the screen might get put in the 'off' position after the downgrade on some PSPs.
I'm not sure why that happens, but pressing the 'screen brightness' button seems to fix it.

11. Format your memory stick using your PSP after you've done the setup.



This downgrader will work on all PSP Motherboard versions.
You will need to have 75% or more battery power to do the downgrade.

This is the latest 'IdStorage Corruption Free' downgrader,
