This is the OTA Full ROM update for Lenovo A3690 TD-LTE 1 GB RAM 8 GB ROM.
After this update you won't have GAPPS (Google Play Store, …) anymore.
If anyone can "cook" a custom rom or a recovery based on this stock OTA rom, i would very much appreciate.
Only with something like that i would see GAPPS (Google Play Store) back on this phone.
There is no way MTK6735 (M / P) can be rooted, at the moment (23 dec 2015). No recovery / full stock rom either for this model.
Thank You !
Happy Holidays !
