Note: This video was made using PRO-B4, but the installation procedure is the same.

The main feature of this custom firmware is the fact it can be used on all PSP’s even those not 100% hackable (PSP 2000 with TA-088v3 mobo, PSP 3000 and PSPGo). The only issue is that it only runs on official firmware 6.20 because it’s based on an exploit found in this firmware. Without further ado, let’s see how to install it:

Requisites

• PSP 1000, 2000, PSP 3000 or PSPGo.
• Firmware 6.20 installed.
• Battery charged at least to 78%.

Warning

Do the following steps at your own risk.  Remember that only you are responsible of what you do to your console. Although I followed this method successfully, I won’t take responsibility if you brick your console.

Installing

1. Download Custom Firmware 620 PRO-B10 fix1 and extract it.
2. Copy PROUPDATE and  620PRO_Permanent folders to /PSP/GAME directory in the memory stick.
3. Go to the game menu and run UPDATE PRO only, or UPDATE PRO and then PERMANENT PATCH according to which method you decide, the no permanent one or the permanent one, respectively.

No permanent method vs. permanent method

There two folders because there are two methods, the no permanent one which allows you to run the custom firmware on the official firmware and leave all as it was after rebooting the console; and the permanent one which install the custom firmware on the PSP, avoiding to lose the hack after rebooting.

Which one I choose?

I think is a matter of tastes, because both methods write the PSP’s memory flash, but only one does it permanent. Maybe the no permanent was useful to be able to connect to PSN with the official firmware.

The purpose of making a pandora battery is to avoid the PSP’s normal boot sequence, to make the PSP be in service mode by reading special files on the memory stick. By analogy, it’s like when we have a cd in the PC and it starts not from the hard drive but from a CD.

There are two ways of making a pandora battery: one way is by hardware, so you have to open the battery and cut a pin. The other way is by software, this is, the eeprom is modified to send a special sequence to the PSP to make it put in service mode. You will use the software method.

I’ve tested several programs to make the pandora battery, among are UltraPandora Installer 4, Hellcat’s Recovery Flasher, and OS Pandora Battery Tool. I suggest to use the latter. So here is the steps:

1. Download OS Open Pandora Battery Tool 0.52.
2. Extract it. It will make a directory named ospbt_052. You have to copy that folder on the MS, into /PSP/GAME folder, so you will have the following directory: /PSP/GAME/ospbt_052.
3. Go to Game menu and run the applications as is shown on the video.
4. In the application select Convert to service mode (aka: pandora’s battery).

NOTE: I recommend to backup the eeprom before converting the battery to pandora just in case, but I’ve never had any issues with the process of making the pandora battery.

After hacking or jailbreaking you PSP maybe you want to run a previously backup-ed game on the memory stick, but this error appears:

The game could not be started (80010013)

To fix this you mus set the right driver for loading games from the memory instead of from a UMD.

UMD ISO MODE

In order to set the driver you must follow these steps:

1. From the XMB, pres down the Select button. A multiple options menu will show up.
2. Go to UMD IS MODE and select M33 Driver with the D-Pad (arrows).
3. Press down the Select button to remove the overlapped menu.
4. Launch the game one more time and enjoy!!
