Some help and, clarification would be very appreciated

No you dont need to go to 1.5.

and since you are one a custom firmware, I would just make a pandoras battery and Ms and udpate to 3.71 M33 using that

guide: http://www.dcemu.co.uk/vbulletin/showthread.php?t=77747


and 3.80 M33 is the latest

I have 3.02 OE-B installed, can I just use the instructions in the second part of your guide "Updating to 3.51/3.52 M33 from any OE or SE custom Firmware"?

Thank you

:rofl: :p


you just answered your own question

yes, you can, hence its titled for OE and SE firmwares

Ok, so I doubt this is going to make me look good around here but... I guess I'll never know unless I ask.

I'm running 3.52 M33. How do I get it to 3.52 M33-4? I need to have that to get 3.90 M33..

www.dark-alex.org
grab the update
place i where it tells you
then run it
afterwards set your kernel to 352

OK...so I know this thread hasnt been posted on for a VEEERRRYYY long time but im kinda hopin someone will reply. Im ONE STEP AWAY from updating my fat psp with original 1.5 firmware to the latest official Sony firmware!!! Here goes...

Ive been off the PSP for a wee while and still had devhook which i now learn is ANCIENT! Im trying to upgrade to 352 M33 (or be it any version of M33...i hear M33 is the best choice now??!). Ive formatted my card to start from scratch, copied kxploit thing, M33 CREATOR, ran both and then gone to run the blue icon M33 UPDATER...here lies the problem...

First message fine, then..."Checking PSAR integrity...incorrect PSAR" ....psp reboots!

I've tried different downloads of the same version and ive tried different versions (351/352). Can someone...ANYONE...please tell me what to do before im tempted to screw it all and do the official Sony firmware update!!! Im on the edge!

hi mate new to all this i have psp its on 1.50 i have followed all info as stated above but games do not play can you help? thanks

Were do i put my ISO game files to play games and do i need any other software on my PSP to load games
