thnxxx guys ill use my warranty..................

 

new 3.60-official slim psp good naaaa........ and im going to upgrade it to 3.71 m33-4. but i know how to upgrade with Pandora’s Battery and i dnt have Pandora hiiiiiiiiii......... dnt know from wher ill get it, if any one can help me to install it without Pandora’s Battery......plz......wating for reply......!!!

 

psp slim's can only go to custom firmwre with the pandora battery there is no other way.

 

i gad one fat psp also can it helps to go to any CFW slim.

 

ok can anyone tell me what are the hardware i need to upgrade it....

 

try the search function your problem has been covered many many times and its actually quite easy to fix. It would be easier if you know anyone with a Custom firm ware (CFW) so that they can create a pandora battery and mem stick for you.

 

man im sorry to say that u briked it. ur gona need to get a pandora batterty to get it into service more from which u need a magic memory stick to have it instal a CFW again
