SamyGO Firmware Patcher

What is SamyGO Firmware Patcher?

SamyGO Firmware Patcher Script is a tool, modifies original firmwares that downloaded from Samsung site and converting them to Hacked firmwares for enabling Telnet on boot, executing start scripts via advanced mode and implement Video AR Fix for to exeDSP programs.

• Why we are using patches instead of releasing hacked firmwares?

Because we are not allowed to distribute Samsung owned firmwares even we modify it. For avoiding any legal problems, we are turning around and modify original software via this script instead of releasing hacked firmwares.

Needings

• Before start, you needed to download 32 bit python 2.6.4 (not 3.x one) for your operating system from www.python.org site.
• Python is OS independent language for using this script at all OS'es.
• You needed pyCrypto package too if you try to modify CI+ device firmwares which has 'CIP' string in that firmware name (ex. T-CHLCIPDEUC).

Usage

• Download SamyGO Firmware Patcher script from download area.
• Download your devices original firmware from Samsung site.
• Extract downloaded original firmware (by double clicking at windows or using unrar program at linux, macosx...)
• patch it using SamyGO Firmware patcher as "python SamyGO.py <Your Extracted Firmware Directory>"

for example:

python SamyGO.py ./T-CHL7DEUC

• Take look at process output

death@triQuad:/SamyGO> python ./SamyGO.py Silo/T-CHL7DEUC
