3.30 OE-A Recovery Menu Guide

To access the Recovery Menu, hold R while powering on the PSP.

This guide should provide you with all of the information you'll need to completely understand the recovery menu. The recovery menu is possibly the single best feature of custom firmware. It allows you to recover, customize, and enhance your PSP in a variety of ways. This guide is designed to document exactly what it does, and how to do it.

I was originally intending to update the guide Dark_AleX already wrote for 3.02 OE-A's recovery menu, but in the end I decided to rewrite the entire thing. I'm not anticipating that this thread will become particularly popular, but I'm intending on linking to it from my 3.10 OE-A installation guide thread, for organization purposes.

3.30 OE-A Recovery Menu Features

Toggle USB - This enables you to access your PSP's memory stick over the USB connection. It is functionally identical to choosing the USB Connection option in the PSP's main interface.
Configuration - This enables you to configure some of the most common options in 3.10 OE-A. All setings are set to disabled by default.

Skip SCE logo - This disables the Sony Computer Entertainment logo from playing when power on the psp. As a result of that, startup time is slightly faster and UMDs will no longer autoboot.
Hide corrupt icons - This hides the corrupted icons generated by Kxploited homebrew (homebrew that comes in two folders). This can slightly slow down your GAME menu if you have a large amount of homebrew.
Game folder homebrew - This lets you choose whether to load programs at /PSP/GAME with the 3.10 kernel or the 1.50 kernel. Unless you need to play downloaded PSP demos, it is strongly recommended to use the 1.50 kernel.
Autorun program at /PSP/GAME/BOOT/EBOOT.PBP - This will allow you to run the EBOOT located at /PSP/GAME/BOOT/EBOOT.PBP whenever your PSP starts up. This feature is used by some homebrew programs, such as password lockers. Any eboot ran in this way will run on the 1.50 kernel.
Use NO-UMD - This will enable you to run backup games from your memory stick without needing to have a UMD in the drive. Compatibility is somewhat low, so I can't recommend using this feature.
Fake region - This will allow you to set the psp kernel region to either Japan, USA, Europe or Korea. Setting the region to Japan enables you to visit a video download service through the Network section of the PSP's main interface, but it is impossible for people outside of Japan to download videos at this time.
Free UMD Region - This enables UMD movies and music to run region-free.

Run program at PSP/GAME/RECOVERY/EBOOT.PBP - This will recover your PSP if it has been semi-bricked. More information on how to recover is listed further down in this thread.
Advanced - This enables you to configure some advanced options and mount your PSP's internal flash to your computer via USB. Messing with this stuff without knowing what you're doing can result in a permanent brick, so be very careful here. If you want your PSP to be as safe as possible, you have no reason to ever open this menu.

Advanced Configuration - This enables you to configure several advanced options which are completely useless to the average user.
Plain modules in UMD/ISO - This allows certain forms of unsigned code to be run from within an ISO. There aren't really any practical uses to this function, and it can make some UMDs and ISOs incompatible with your firmware. Developers can use this function to experiment with running homebrew from within an ISO.
Execute BOOT.BIN in UMD/ISO - This runs BOOT.BIN inside the ISO instead of EBOOT.BIN. Useless unless you're a developer experimenting with the Plain modules in UMD/ISO feature, you shouldn't use this feature; average users have no need to toggle this.
Use isofs driver also in UMD-inserted mode - Runs UMDs using the ISO driver. For non-developers, this will do nothing more than reduce compatibility.
Toggle USB (flash 0) - This enables you to access your PSP's internal flash 0 memory over the USB connection. Messing with these files can result in a brick; there is simply no reason for the average user to use this feature.
Toggle USB (flash 1) - This enables you to access your PSP's internal flash 1 memory over the USB connection. Messing with these files can result in your settings becoming corrupted.
CPU Speed - These settings enable you to change how fast the CPU runs in games and in the PSP's interface and web browser. Higher numbers will result in better performance at a cost of battery life. PSOne games cannot run playably below 333, so an option to customize their speed isn't included.
Speed in XMB - This determines how fast the processor will run when it isn't playing games. If you browse the internet or watch movies, you might want to increase the speed.
Speed in UMD/ISO - This determines how well games will run. The higher the value, the higher the framerate. If you experience any slowdown in a game, increasing this number should eliminate it.
Plugins - You can use this menu to enable any PRX plugins that you've copied to your seplugins folder.
Registry hacks - These settings allow you to change a few registry-related settings in the firmware.
Button Assign - This allows you to change whether the PSP should use circle or X as the enter button.
Activate WMA - This allows you to activate WMA playback. Normally, 3.10 won't let you enable this without connection to Sony's servers using a wireless internet connection.
Activate Flash Player - This allows you to activate the PSP's Flash Player. Normally, 3.10 won't let you enable this without connection to Sony's servers using a wireless internet connection.
Exit - This exits the Recovery Menu and attempts to launch the PSP's firmware.

How to flash a clean 3.10 OE-A firmware from the Recovery Menu

This technique can be used to re-flash 3.10 OE-A without having to first downgrade to 1.50. If you do a lot of flashing on your 3.10 OE-A PSP, you should complete this process and leave the recovery folder on your memory stick.

Download and decompress the 3.10 OE-A Reflasher package
Copy the directories oeupdmaker and oeupdmaker% to /PSP/GAME150/
Download and unzip the 1.50 Upgrade Eboot, name it "150.PBP", and put it in the oeupdmaker folder
Download and unzip the 3.10 Upgrade Eboot, name it "310.PBP", and put it in the oeupdmaker folder
On your PSP, run the 3.10 OE-A Update Maker program. This program will create a file called DATA.DXAR in the oeupdmaker folder
Copy the folder RECOVERY you just downloaded to /PSP/GAME/
Move the generated DATA.DXAR from oeupdmaker to the RECOVERY folder
Start your PSP in Recovery Mode, then choose "Run program at /PSP/GAME/RECOVERY/EBOOT.PBP". This will flash the DATA.DXAR file to your PSP. Don't shutdown the PSP or remove the memory stick until the update is finished.
Once finished, shutdown the psp and restart manually to 3.10 OE-A. You then need to restore your default settings from the system settings menu.
