Hi,

I want to convert my single sim G930F phone to dual sim (read/write cert). I read forums the z3x Samsung Tool can't read /write cert file in andoid 8, only 7. The problem is my android version is the newes android 8 binary 6. I think downgrade is not possible to android 7.
My question is can I read/write cert file, if I use combination file? Of course if will binary 6 version (now exist only binary 5).

Thans!
