I'd like to start by saying that I've searched these forums and a few other ones for an answer to this problem, but I can't find anything that fits my situation.
As stated, I have a fat OFW 3.06 PSP. I created a Pandora Battery using the fat CFW 3.71-M33 PSP I modded for my friend months ago. I used this guide. Everything went well.
I put the memory stick and battery in my OFW PSP, and upon starting up, it did nothing at all (the green light came on for 10 seconds, then shut off, with *no* screen response at all). Then I started with holding L, and it booted into the Extended Pandora menu as intended. I went to the Pandora main menu, and selected the first option, to install 1.5 on the PSP. I agreed to patch the motherboard as it required, and the flash started successfully, but gave two "PANIC" errors about not being able to read/write the IPL file. Everything after that went fine though, and it told me the installation was successful, and to reboot with the regular battery and such. Doing that just led to the same 10 second problem as mentioned above.
I then rebooted into Extended Pandora and selected "Fix flash1:/", which also didn't help. After that, I went back to Extended Pandora and booted 1.5 from the memory stick. From there, I attempted to install 3.52-M33. That met with failure at the very last step, when it mentioned a problem with "lflash_fatfmt.prx", which resulted in the process stopping instantly and restarting the PSP back into 1.5 (still being read off the memory stick).
The problem is... I followed that initial guide on creating the Pandora Battery so I could still use the battery for regular use afterwards (I currently have no battery and zero money to spare getting one). All the solutions I see so far for unbricking require either creating a version of Pandora Battery that (apparently) can't be reverted, or entering Recovery mode (which would be by holding R upon start-up, but that never works for me, no matter which battery I use).
So what I'm basically wondering is... does anybody either know a solution to this specific problem that doesn't require me basically making a battery useless? Or if there's a thread I missed that can fix this problem (or fix not being able to enter Recovery mode), can you possibly direct me to that?
Nevermind. This is a fine example of not trying *everything*. For those of you that may come across this very same situation...
All I did was start Extended Pandora, and selected the option to install CFW. I hit O first to select the directory it was in, and since I had already run M33CREATOR, the necessary installer was already created and ready to be used, so I selected the M33UPDATE folder (where the installer ends up). Then I selected the option again (this time with X), and the installer fixed up my IPL situation (well, it seemed to, as it mentioned something about straightening it out, though not in those words), and the installer completed successfully. Now I just have to restore the Pandora Battery (which, since the instructions said NOTHING of backing up the eeprom, I'll have to create a fake one... stupid guide... ::grumbles::).
