After a lot of questions about installing update .ZIP files and custom ROMs on the Jiayu G4 we have decided to put a basic “How to guide” using ClockworkMod Recovery here. This is a work in progress and will be updated later with more information.
Currently there is no known English version of CWM Recovery so Chinese is the only option.
How to install ClockworkMod Recovery JiaYu G4
