Pandora Battery!! UNBRICK ANY PSP!

[m1v3cs]

Pandora Battery release by Prometheus/c+d !! UNBRICK ANY PSP! thx noobz

We told you that we'd be releasing an unbricker for the M33 bricks. But then we got to thinking, maybe that just wouldn't be exciting enough. Would you like a super special surprise bonus? How about an unbricker for ALL PSPs? Yep, you read that right.
We call it "Pandora's Battery".

There's a larger story behind this unbricker, though, and it deserves to be told. It's the culmination of years of behind-the-scenes research and development by some of the top names in PSP hacking, under the name of the Prometheus project. This group of people, from various development teams, was dedicated to developing and releasing PSP hacks and exploits, with the aim of improving the status of PSP homebrew, and making sure that it was kept alive.

For some time this project was highly successful - many releases from Noobz, C+D and others were direct results of this work. The zenith of this success was the development of this unbricker - which required some amazing technical leaps, including:

1. Reverse engineering of the service (unbrick) mode
2. Development of a technique to change an ordinary battery into a service mode trigger battery (and back)
3. Development of custom IPL code along with a technique to sign that code as authentic.

Even more impressive is that all of the above was achieved without any access to the official hardware or software. With careful nurturing, this unbricker and custom IPL was to become the foundation of a whole new homebrew environment. Unfortunately something happened to shatter the idyll. Somehow, the unbricker was leaked into the wider world before it was ready to be released. Whether this was deliberate, by one of the team members, or accidental via a security breach is still unclear. The fact is that this unbricker appeared on the black market, being sold for huge prices. As far as we know, it is probably very close to the same software that appears in at least some of the 'magic unbricker'/'jigkick' videos.

So, although the time was not right to release this (it would have been wise to wait at least until the PSP Slim release), our hand has been forced. In order to prevent small fortunes being made by leeches, we are giving this unbricker away for free. So - let it be known - if you have paid for an unbricker, then you have been ripped off. I suggest that you take up your grievances with the seller - it should never have been sold. And if you're unhappy about this being released before PSP Slim - then blame whoever it was that leaked or stole it.

It's unclear whether or not this is the end for the Prometheus project - hopefully not, but that is undecided so far. In case it is the end, it is worth a quick roll of honour. In alphabetical order:

Adrahil, Booster, Cswindle, Dark_AleX, Ditlew, Fanjita, Joek2100, Jim, Mathieulh, Nem, Psp250, Skylark, TyRaNiD.
And here are their respective C+D (Create and Destroy) nicknames.

Mathieulh = WiseFellow
Tyranid = bockscar
Fanjita = FullerMonty
Joek = CosmicOverSoul
Dark_Alex = Malyot
Chris = Caretaker
Adrahil = VoidPointer
nem = h1ckeyph0rce

Anyway - make sure to read the readme.txt in this release for how to use it, but in brief it works like this:

1. You run a program on a homebrew-enabled PSP that will convert a standard PSP battery into a jigkick battery. Note that you can't then use that battery normally - so you should use a spare one.
2. You run a program to generate the unbricker memory stick image, built from the v1.5 update EBOOT (note that this, and the custom IPL, means the release is completely free of Sony copyright materials).
3. You run some programs on a PC to install the image to your memory stick.

Now, you have a battery/memory stick pair that works just like the famous jigkick combination (but better) - just insert them into any PSP (even a brick) and the PSP will be reinstalled with the v1.5 firmware. As far as we know, this will continue to work for all future firmwares.

Enjoy! And remember - if you find this useful, please donate to the original developers - it's a lot cheaper than paying ?1500 for it on the black market... Donations via paypal please via this button:

Unbrick or Downgrade any PSP using Pandora's Battery Guide

Requirements

Software Requirements
♥ 1. Pandora's Battery Files
♥ 2. 1.50 Sony Update
♥ 3. WinRAR or 7-Zip

Hardware Requirements
♥ 1. Two separate PSP's:
♥ 2. A PSP you want reflashed
♥ 3. A non-bricked PSP to prepare the files on. This PSP must also be capable of running 1.50 homebrew.
In theory, this could be done with one PSP. However, this PSP would need to be non-bricked, and capable of running homebrew. It would be much more efficient to use a homebrew flasher in that case. Therefore, the Pandora Battery should only be used to downgrade PSP's or un-brick PSP's.
♥ 4. A spare battery, of any make. After this process is complete, the PSP will not boot into its normal state with this battery
♥ 5. A spare Memory Stick Pro Duo, at least 256MB, less than 4GB. The Memory Stick Duo will not work, it must be a Memory Stick Pro Duo

Preparations
Memory Stick Preparations

♥ 1. Using a USB cable, connect your PSP to your PC.
♥ 2. Backup all data on the Memory Stick.
♥ 3. Using any utility, format the Memory Stick.
♥ 4. Using WinRAR, open up the pandora.zip file you downloaded (if you haven't already, it's in the Requirements section)
♥ 5. Double click on the msformat folder, and run msformat.exe
♥ 6. Remove the Memory Stick and disable the USB connection
♥ 7. Put the Memory Stick back into your PSP, and re-enable the USB connection.
♥ 8. Create a folder called PSP in the root of your memory stick (X:\PSP, where X is your PSP's drive letter)
♥ 9. Create a GAME folder inside the PSP folder on your memory stick (X:\PSP\GAME)
♥ 10. From the pandora.zip file, copy the contents of the battery folder and the installer folder to the GAME directory you just created (X:\PSP\GAME)
♥ 11. Rename the 1.50 Sony Update you downloaded to UPDATE.PBP
♥ 12. Copy the UPDATE.PBP file to the root of your memory stick (X:\UPDATE.PBP)
♥ 13. Remove the Memory Stick and disable the USB connection
♥ 14. Put the Memory Stick back into the PSP

♥ 4. Boot the PSP. A menu will appear. Follow the onscreen instructions to reflash your PSP.
♥ 5. When the flashing process is complete, restart your PSP.
♥ 6. If all goes well, a blue screen will appear, telling you that your settings are corrupt, and to press circle to repair them. Do so now, rebooting your PSP if necessary.
♥ 7. You should now have a 1.50 PSP

FAQ

Can this downgrade any PSP?

♥ ♥ EDIT: Yes, you can unbrick any PSP. this can also be used as a downgrader on a non-bricked PSP.

Do third party batteries work?

♥ ♥ Yes, according to Fanjita, he uses a Datel brand battery.

Can I restore my battery back to its normal state after this process?

♥ ♥ No. That is why you need a spare battery. Freeplay has found some very cheap batteries here. Get them while they're still cheap

I know the battery can't be restored, but can the Memory Stick be reformatted and reused?

♥ ♥ As far as I know, yes. However, the you will need to redo all of the steps in the "Preparations" section related to the memory stick.

Does this work on TA-082 motherboards?

♥ ♥ At the moment, I'm not sure. But feel free to try it, what's the worst that could happen? You brick your already bricked PSP?

[morel119]

Dude, thx for the detailed guide.

But I have one question:

Can the Pandora's Battery go bad or something, like making black screen and not work or something?. Cause I saw some threads about it not working.

[joelles]

It's not working because I think they might have follow the instruction wrongly as the instruction guide is not really specific enough. Here's a more specific guide:

Step 1: Extract the .ZIP file.

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 "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:\psp\pandora\mspformat>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: Copy the Firmware 1.50 update 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" into the folder called "msinst" that was extracted from the ZIP file.

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:\psp\pandora\msinst>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. With a working PSP or memory stick reader, copy the firmware 1.50 update file into the root of the "magic" memory stick, namd UPDATE.PBP, just like in step 15 above.
2. Insert the "magic" memory stick.
3. Insert the unbricker battery. Your wifi, memory stick, and power lights should all turn on temporarily, and a menu should appear.
4. Press X. After it checks the update file, you should get another menu.
5. Press X to write Firmware 1.50 onto the PSP.
6. Now you have a unbrick PSP with 1.5 firmware...congrats!

[blackhive]

in the folder there's so manyEBOOT.PBP, so how do oi know which one is the 2.50 firmware?????

[hitman3]

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.

joelles can you please explain this one in more detail ? does this mean that even the battery can be saved ?
if yes then how ?

[Petak_Green]

My God this really lift up my spirit of a chance that there is a way to unbrick my psp. And can someone tell me if i can still play a downloaded game after i reflashed my psp? Thanks In advance,especially to all the legendary and great psp hackers out there, wherever you are.

[hitman3]

♥ 11. Rename the 1.50 Sony Update you downloaded to UPDATE.PBP

Sir M1V3CS - this isnt included in the pack you've uploaded - do i have to download it from qj.net ? can you please simply provide a link here or upload it yourself ?

EDIT - ok i've got it - if anyone else needs it - here's the link - http://dl.qj.net/index.php?pg=12&fid=163&catid=163

[joelles]

joelles can you please explain this one in more detail ? does this mean that even the battery can be saved ?
if yes then how ?

you need to run the Pandora Battery Creator again in order to make the Battery to work as normal PSP battery otherwise it will only works as a part of unbricking PSP hardware.

[hitman3]

ok i have unbricked my friend's psp using the procedure a few minutes back..phew..

you need to run the Pandora Battery Creator again in order to make the Battery to work as normal PSP battery otherwise it will only works as a part of unbricking PSP hardware.

thanks for the tip - i already came across this over at qj just now..
just got through their guides.

[joelles]

My God this really lift up my spirit of a chance that there is a way to unbrick my psp. And can someone tell me if i can still play a downloaded game after i reflashed my psp? Thanks In advance,especially to all the legendary and great psp hackers out there, wherever you are.

Once you use the Pandora Battery to recover your Brick PSP, you will have the 1.5 FW on your PSP. You can either use devhook to load those ISO's games or install any custom firmwares to enjoy more homebrews and customise XMB themes. Enjoy!

Unbrick or Downgrade any PSP using Pandora's Battery Guide

Requirements

Software Requirements
♥ 1. Pandora's Battery Files
♥ 2. 1.50 Sony Update
♥ 3. WinRAR or 7-Zip

Hardware Requirements
♥ 1. Two separate PSP's:
♥ 2. A PSP you want reflashed

In theory, this could be done with one PSP. However, this PSP would need to be non-bricked, and capable of running homebrew. It would be much more efficient to use a homebrew flasher in that case. Therefore, the Pandora Battery should only be used to downgrade PSP's or un-brick PSP's.
♥ 4. A spare battery, of any make. After this process is complete, the PSP will not boot into its normal state with this battery
♥ 5. A spare Memory Stick Pro Duo, at least 256MB, less than 4GB. The Memory Stick Duo will not work, it must be a Memory Stick Pro Duo
