:'( Im not Sure in this Site will works An Hack Method For playstation 3 Games So I Opened this one. What Does mean modifer 4.xx to 3.55 it Mean Changing Eboot bin from lastlest firmware for example 4.11 or 4.21 that it can't impossible way to play if youre are 3.55 or 3.41 using a Custom firmware, changing way that is Using An Hex Value Programm but naturaly The eboot is encrypted it is impossible to crack them? No, Just Simple found the Hex where the firmware block and will take a message playing trought ingame "your Ps3 Need a Upgrade to 4.xx you willl Update Yes or No". changing the Hex Values form the last firmware is trying to use a program called Self Editor or an Hex Editor. 1)try to open the retail Firmware version form the game and combinate with already modified eboot.bin one i mean use Eboot bin original and copy the Hex form the modified one the eboot CFW 3.55 not The TB eboot 2) Hex Editor method is probaly an hard stuff but if we found the right Hex Codes to Changing Firmware 4.xx to 3.55 will works for sure but will take a lot of work and time to create new Offets And Replace Old one.
