Ive recently just had the same problem as i was using 4.01 m33-2 on a phat psp1000 the safe way is to go through the updates instead of straight to the newest. so you start with 5.00 m33-6, this takes you to the latest M33 update

you will find this here ( File Details-CFW-5.00-M33-6-PSP - )
you also nee the offical sony update 5.00 and you will find this here ( PSP Downloads | 5.00 Firmware Update )

unzip both files and rename the offical sony update to 500.PBP then put this in the same update folder extracted from the other zip.

to install, put the update folder in PSP/GAME/ on the psp and run
There, now you have 5.00 M33-6

delete the update folder off the psp now

now you have to go from updates gen-a to gen-b to gen-b2

Gen-a Found here ( File Details-Custom-Firmware-5.50GEN-A-Build-4-PSP - )

unzip and put the UPDATE file into PSP/GAME again and run
Done

now get gen-b here and do the same as above and run( File Details-Custom-Firmware-5.50GEN-B-PSP - )

when you have done this check your psp system information and you should see gen-b(full)

now get ( File Details-Custom-Firmware-5.50GEN-B2-PSP-Homebrew-Applications - ) and run as the same as the rest..

now you are done your system information will still say gen-b(full) still as the b2 was just a small update

THIS IS THE BEST WAY AS IVE WITNESSED A BRICKING FROM GOING STRAIGHT TO THE GEN-B UPDATE

most games will now work but if you will still need 2 programs called UMDgen4 and Yoshihiro's Decrypter V2 and these will change the eboots on how the games load up...see link (How to use Yoshihiro's decrypter to play 5.55 / 6.0 psp games | Free PSP Game dowloads iso cso psx all full no trial )
follow these instructions and you will be away with the new GT, FIFA etc and future releases (you are the man Yoshihiro):smashin:

Not had any issues reported by updating from m33 to 5.50 GEN-B2 in one easy step

using Yoshihiro's XGEN Updater v2, the easy installer for 5.50 GEN-B2

thats cool, i didnt even know that he had done one, he didnt have it out when i updated mine. this new one was created 1st of october so not too long ago..... thanks for bringing this to my attention
:thumbsup: yoshihiro rules

Apart from the obvious of playing the newer games, is there any benefit of updating to this, or should I just wait for a new m33 update?

The reason i updated to Gen-b2 is because M33 was no more, dark alex who created it said he was no longer doing it.... and his website has been down for a while now too so i wasnt going to wait about.....gen-b2 just as good trust me,:smashin:

I think my mates lads is M33 3.8 i assume you can jump straight to 5.5 gen B2 with this download link then. Can someone just confirm so i don't cock it up. Ta

cant confirm but have been told it works, but if your not too sure about it just follow my steps at start of thread for updating, i was on a earlier m33 and now im gen-b2, works perfect and just make sure you psp is fully charged when doing so.... :smashin:

Put the update in game folder and also it will not affect your games in any way. Put the 550.pbp on root.
