G930F no sound through earpiece or speaker on 6.0.1

[decco]

Hey,
i have a small/big problem,, on my g930f.

if i have android 7.0 then speaker and ear peace sound is ok when calling,
but if i write back 6.0.1 and repair imej, then patch certificate, then io have no sound..

any suggestions?

tried various modem downgrades, same problem.

Z3x box has no support on 7.0 patch certificate.. its simply not supported.


So maybe someone know certain firmware or any file that can help me?

something is updated who cant be downgraded when flashing older firmware, so thats why there is no sound ?

im using 28.2 version of samsung tool pro
