help me please.. 1.50 eboot troubles

Every memorystick I have..i if I use dark_alex's stuff . It says it "invalid 1.50 update file (3)"

if I use any of team m33's stuff.. it says" the SHA1 file doesn't match expected" or something similar...

even if I try to use the downgrade helper..(to try and get a enw 1.50 eboot that could help me)

it messes up...

I've tried each and every oen of those options on each of my memsticks:

SanDisk Memory Stick PRO DUO 256 mb
SanDisk Memory Stick PRO DUO 4 gb
Sony 32 mb





Can someone please help me? all I want to do is get one of those firmwares installed..

please..

try going to psp-hacks.com to get the 1.50 eboot and see if thats works

I've tried that..I've tried dl.qj.net, psp-hacks.com , and pspupdates


I just don't know why it won't work...(besides the SHA1 thing)

try formating the memory stick infat and if that does not work fat32, then ntfs.

what are those things?

dang..still nothing?

Try these!

On the PSP: go to system settings format mem stick (backup files first!)

On the PC: if above didnt work plug in USB and open command prompt, type chkdsk /f X: and press enter, this should fix any errors!
