hey guys, i own a psp 3k with 6.20 firmware...
I was messing around with a hex editor named "XVI32",
i opened the eboot of my 6.20 update file and replaced all the "6.20" characters with "6.21",
i then copied them to my psp and then tried to upgrade....
The psp actually prompted to update
just a thought, maybe this can be done with a 5.50 GEN Eboot (replace the 5.20 characters with 6.21) and then get 5.50 GEN running just with a name of 6.21
Is this possible guys??? anyone with a psp phat (with pandora)... can u try the 5.50GEN process and confirm this?????
