HOW TO GET IT TO WORK ON 5.50 GEN-B!



First of all, make sure you have CFW 5.50 GEN-B.

Now get into recovery mode > Advanced > Toggle USB (flash0)



Now on your PC, create a text file in notepad and copy/paste the following line:



release:5.55:

build:3062,0,3,1,0:builder@vsh-build6

system:50781@release_550,0x05050010:

vsh:p6399@release_550,v50953@release_550,20090415:

target:1:WorldWide



(NOTE: In notepad this will appear as one line, keep it like that)

Save the text file as call it ''version.txt''



Now, go to Computer > Memory stick (Flash0) > VSH > ETC

Here you will find the version.txt file. Make a backup and then copy the version.txt file you just made there. Overwrite it.



Now, you will ''trick'' the game so it thinks you have firmware version 5.55, while you actually have 5.50.
