[zaza34]

hi here, i have 2 s6 edge 925f, i ulocked both phones with z3x box.
but for this i downgraded phones from 7.0 to 6.0.1, lost imei and s/n.
after repair phone's imei and s/n, flash 7.0 vertion. now everything works well,
exept wifi and bluetooth, they dosenot work corectely.

after reboot phone wifi is on and i can put in password and wifi works, but if swiched it of, phone needs restart, otherwise wifi dose not work.

to turn bluetooth, phone needs ,,reset network conection''
then bluetooth works corectly. (i can swich it on or of many times)

now vertion is 7.0, but same problem with 6.0.1 and 5.2

any ideas? can you give me corect direction?
