PSP How to completely factory reset my psp, not just memory stick

[uhhuser]

Hi, soo i just bought a psp 2000 and ive installed ark4 on it
yesterday but the games didnt want to boot up (i think i was
just impatient looking back) so i decided to reset it and now
i cant run anything on it and ive been trying to change it to
ofw 6.61 but its stuck on pro, if anyone could please help,
also the app starts, then the screen goes black and it shuts
down

(when i hold down power and r it boots in the cfw pro screen and its in russian, even if i remove the memory stick)

You likely have installed pro in way where it replaces some parts of the boot process to have PRO boot with the system. You likely need to do full FW reinstall. Though, full factory reset would likely still keep pro around in this case. I am though, also guessing. You might have a half state of PRO where some of it's components are missing from the memory stick, but again, guessing, comparing this to 3DS. Though, if "change" wording meant you tried to indeed install OFW already, all you can try to do is to also do the full system boot install of pro after the OFW firmware reinstall. I think full removal of PRO needed it's own tool, same one that does the type of install.

Wasn't there a recovery menu by pressing some button when PSP was turned on? from there it might be possible to reinstall FW. I vaguely remember when I used my PSP with pandora battery, it was very easy to put the CFW.

There should be instructions somewhere on the net for doing a full official firmware install to overwrite anything related to modding the machine, I reset mine back to the latest official firmware as I traded it in after I upgraded to a modded vita.

I recall you just put the firmware into a specific folder on the memory card and you install frimware update through the official mean, I forget the exact steps but it's basically updating to official firmware if you want everything close to factory settings. Best results from doing a factory reset after installing the official firmware. That's pretty much what I did, you'd never know it was modded after that. I did it over a year ago though so my memory is a little hazy on it.

As for the russian showing up, sorry, not something I've experienced personally so I've no idea why that happened.

if the folder is PSP/GAME/UPDATE/EBOOT.PBP, im afraid id doesnt work, the "Playstation Portable" screen pops up, stays for a bit then my console crashes

i think its installed in the console itself, not the memory stick, correct me if im wrong but this is my first handheld so idk much, it still shows 6.60 PRO B-10 even when i remove the memory stick and it still boots in pro cfw when i hold down power and r

Yeah. In this case, reinstalling the OFC fully should be done, possibly from recovery mode or something. Like said, if I recall correctly, If full OFW reinstall does not remove PRO firmware that is installed on your system, rather than just launched after boot, you may need the additional tool shipped with PRO firmware for PSP that would do such permanent install, at least for some models. I forgot PSP specific circumstances as I have used mainly stuff on vita, I'd wish I still could check how things were on my 3000, but these things depend on PSP model too.

You have to uninstall the cfw to be able to reinstall the ofw
