I tried to manually update my phone to emui 5.0 and Android 7.0, it didn't work and I had to do a hard restore, so now I have it running but it is at 3.1 for emui and Android 5.1 beta, the model number was Eva-l09 now it's at A168-L09, how can I get my phone back to the version it was at, tried the updates on emui, in settings and hi care, any help would be greatly appreciated thank you
