upgrading form official 1.50 firmware to 3.52 M33

I've done everything it said in the readme file. Only thing that's stopping me is when I execute 3.52 M33CREATOR.

It says " loading 1.50 firmware...SHA1 of psar doesn't match expected"

I have the official 1.50 eboot.pbp(renamed 150.pbp as it said in the readme) and all the other stuff needed.

Just someone please tell me how I can fix this problem. please?

try downloading a different 1.50 eboot and see what happens

make sure its not called 150.pbp.pbp check in winrar if its called that and on your desktop all u should see is 150.

That's one of the problems though. When it's just named 150..it shows it is just a file and is not picked up by the M33 Creator. When it's 150.pbp .. it is shown as a pbp file and is picked up by the M33CREATOR

but the SHA1 problem then comes up..

I've tried downloading two different 1.5 eboots ..but they are the same file strangely.

Do you all know of any other websites besides pspupdates.qj.net and pspcrazy.com ? that i could download the 1.50 eboot from?

alright i know a link and here it is i used this eboot to update so i know it works here it is

I have also encountered that error. I've tried to download in different sites containing the official eboot file, and im successfully updated with that

Try this link..http://dl.qj.net/PSP-Firmware-1.50-F...163/ catid/163

to steve's reply: ... dang it..that one doesn't work either.. the same "SHA1 of 150.pbp psar doesn't match expected. Press X to exit"

to kryst's: the link doesn't work strangely?

hmmm strange it worked for me why dont you re-download the m33 files.
here where i got my m33 from here its 3.52 M33 go here http://www.psp-hacks.com/file/1210

I did..still for some reason ..it keeps saying that annoying SHA1 problem.

so u downloaded that file i gave u and the eboot.

the eboot yes and the file you gave me yes...

sigh...

does anyone think it could be the memstick?

my memstick is a: SanDisk MemoryStick PRO DUO 256 MB

is that one that usually messes up?(i've emulated on it before if that count's for anything)
