I have S6 with Android 6.0.1 under Movistar Argentina 4G services ..
I read in the net about this issue but until now i can't find what is the solutions about this .
Some people recommends a downgrade to android 5.1.1 because android 7 upgrade for this phone not is avalaible at this time .
I can test with android 5.x.x or android 7.x.x for another country like india ,serbia ..but i have some questions ..
For this first step i can backup factory firmware or download this one ,but i don,t know if i use band base version with diferent description ..
I have G920IDVU3PI4 but i find firmware with same eq id but dif base band version ,.. I can install firmare with diferent base band in restore case ??
I can try with Chile version or another local carrier like Personal o Claro Argentina version but base band are diferent ..
Someone I help me or tell me if i can use same android version with diferent base band version ??
Any suggestions ?
Thanks in advance .
