i have a first gen psp to say the least . its also upgrade to firmwre 2.6. ive been searching lots of forums including this one in trying to help me downgrade this bad boy for i can run homebrew. ive tried to upgrade to 3.03 but it says the file is corrupted so if anyone can point me in the right direction it would really help thanks

1. if you have the pandora battery you can downgrade with that
2. since your at 2.6 you can downgrade using gta lcs.
3. you can upgrade to 2.71 so you can downgrade without using nothing. check my tutorial in the tutorial section on downgrading 2.71

how do i use gta lcs i have a rented copy from blockbuster right here ?

well make sure its the orignal GTA:LCS and you can follow the guide here>> http://www.pspbrew.com/forum/viewtopic.php?t=7034 BUT I WOULD SUGGEST you downgrade with the 2.71 downgrader which u can find here http://pspupdates.qj.net/2-71-PSP-s-say ... /aid/63896 but if you have TA-082 motherboard click this one>> http://www.pspbrew.com/forum/viewtopic.php?t=6810

2.71 requires passing of some 1.50 files how do i get those
