ok, id installed the custom firmware using my 32mb card (my friend had my 2gb card to take some stuff off for his self) got to work, put my 2gb card back in and devhook wouldnt work, i got home, tried to downgrade (using the non-gta method, using a tif file, id done a friends this way)the screen was going red but the memory card light wouldnt flash, so i panicked, posted on here, then realised i hadnt got the right folder on my big card to load 1.5 eboots, so now it all works lovely, thanks for all the help though.
im sure i read somewhere that if you hold r as you boot up the psp theres a way to go back to 1.5, i know theres no need now but i like to know i can if i want.
