I have a psp slim with sony's 3.71 fw...
Can you downgrade using this guide??
On PSP Slim units, a menu will not appear due to display driver issues, but still press X to begin the 3.71 M33 installation.
x3sphere, time to update this particular line (above)?
Hello again. Altogether, how many times is the memory stick formatted to get a magic memory stick? 2 or 1? My friend's been telling me you need to format it once on the PSP, and once through the computer. Do I format it on the PSP slim first, then after it's done formatting, connect it to the computer via USB and format again using DOS?
so i cant get 3.71 M33-2 on a psp slim with a slim battery..? no possible way?
I have a problem.
I have (actually, had) a PSP runing 3.71 M33-2 +1.50 kernel addon.
For testing purposes I created Pandora battery and Magic MS following this guide, and tried to install 3.71 M33.
Everything went fine, i got black screen (with text) where i was asked to press X to install 3.71 M33, i pressed it, and after a ton of lines scrolled on the screen, it asked me to press X again.
I pressed it, and PSP was turned off.
I took out pandora battery and memory stick, and tried to boot PSP (with plugged AC adapter of course), and it started to boot. After the SCEE logo, stripes came out, time and date appeared, but in that moment psp just freezed!
Bad install? Hm... I inserted Pandora batt, and ms again run the instalation again, but hell, same thing, it just freezes on the part which i mentiond above.
What is the problem here?
I have used old guide, and succesfuly downgraded two PSPs. But I could boot PSP with plugged AC adapter (mainly because of restoring eeprom to battery).
I don't understand what is wrong now. Please help.
EDIT: And just to mention, I can enter recovery, if it means something.
thx. sorry about all the questions. im new to this.
but is the Pandora's battery able to fit in nicely into the slim psp?
just wondering before i buy a psp whether i should really get a slim.
ohhh so pandora's battery is only used for INSTALLING 3.71 M33-2??
lets say:
i buy a slim psp; i take out the slim battery and put in my friends phat Pandora's battery; install the custom firmware; then take out the Pandora's battery and put back in the slim battery; aftewards slim psp always succesfully boots up 3.71 M33-2 with the slim battery inside.
Would that be the case?
Thanks alot for your help, i appreciate it.
Im thinking on trading my PSP phat to gamestop and getting the psp slim and lite star wars edition with other credit. Is it possible to trade in the psp phat without the battery (so i can create Pandora's battery with my brothers phat) and get full credit?
