I checked in the section of "tools" and there is a file called cdn_firm.py, with another file called msetdg.py, i read the "readme" and it says that to produce a firmware.bin i need to use cdn_firm.exe, so, all i have to do is rewrite cdn_firm.py to an exe format?Installation failed means that you likely did not place the correct firmware.bin file onto your sd card. Make sure it is the latest firmware.bin created using the python tool.
