I'm on NA5 rom with Mk6 modem. I want to downgrade to MH4 4.1.2 with MG2 modem.
I would like to know if I do this will I get IMEI issue.
Can somebody tell me is MG2 a EFS V2 modem or EFS V1 modem?
From July 2013 (XXEMG4) onwards, official Samsung ROMs change the format of your EFS Directory/Partition. Let's say these ROMs change from EFS v1 to EFS v2. Only basebands from July 2013 (MG2) onwards can read EFS v2.
