I am not a Developer so everything u find here comes without warranty! I tested the FTF-File and had no problems on my SGP312! But this
wont mean it is the same for u ... Whatever u do with the files u find here, u do it at ur own risk! I am not responsible for any damages!!!
Here we go:
FTF-File to use with Flashtool
this is Stock Firmware 10.1.C.0.370 from Japan
i guess it makes no difference whether it is Japanese or somewhat else!
CWM-Flashable-ZIP to use u need to read here
this file is slightly modified ... for lack of time it is same like this
maybe root works out of the box ... ef not flash this one to make sure root is correctly installed.
Maybe root is not stable ... dont know ... i could not test the cwm-zip-file ... ef so pls tell me! i can upload another zip-file
contending a modified install-recovery.sh file! Maybe that helps!!!
