[Mod] Alps A850S (Lenovo A850 clone)

Hi everyone,

Modem installed and works perfect.

Anyone noticed the battery duration is a little bit reduced?

About the GPS thing, i noticed the drivers installed on the ROM are referring to the MT6227 chipset but i think this phone mounts a MT6220, it could be the reason it doesnt work (not satellites found in MobileUncle GPS test).

Louis777, did you try porting a 6582 rom using MTK Firmware Adapter Tool?

Works fine!

Also if someone have trouble with replacement modem.img - delete /data/nvram folder. Works for me

Looks like the gps control files are in the system/xbin/libmnlp and mnld folders....

What about extract this folders from another MT6582 device with working GPS and patch it to ours? Anyone can do it?

For example i think our device is nearly similar to the Wiko Rainbow, which has the same build version. Has anyone tried to adapt that ROM to ours?

[Nah]
