Hi noob warning!

I just modded my brand new psp to 3.40oea. everything was fine on day 1. Day 2 certain csos stopped loading. the psp just hanged. i had to restart by using the power switch.

so now i want to return to 1.50 and then reflash to maybe 3.51m33.

but i just cant get any info on how to revert back to 1.50.

Help me please!!

hi to go back to 1.50 you need to google the 1.50 recovery winstaller,however if you just want to upgrade you can go straight up to m33 i suggest 3.52m33 it has the most features
you could use this

hope this helps

oh and also you could try going into recovery mode then go to advanced/advanced config and make sure all the options are set to disabled i had to do this when i was on 3.40oe

Even tho you could go from the OE CFW stright to M33 CFW I would still downgrade to 1.50 then upgrade to 3.52 M33 then 3.52 M33-4

Here is the RECOVERY folder.

Place it in the ms0:/PSP/GAME folder

So it will be ms0:/PSP/GAME/RECOVERY

Now boot into recovery mode and choose the option...

RUN PROGRAM AT /PSP/GAME/RECOVERY/EBOOT.PBP

Then follow the on screen instructions.

You will then be back to 1.50 so you can update to 3.52 M33 then to 3.52 M33-4

yeap.

I had to with my sons.

Went to 3.40 OE-A to 1.50 then tried running the M33CREATOR and it wouldn't run. Did the patch and after I patched it the M33CREATOR then started.

But do it your way if you doubt the steps.

@sicdude

I still think it is better to downgrade to 1.50 then upgrade to 3.52 M33. I have read so many threads on this site plus other sites of users having issues going from 3.40 OE-A to 3.52 M33.

Dosen't add that much time downgrading to 1.50.
