I flashed ROM on my huawei p8 lite and its started to asking SIM network lock pin. Though it was not locked before I thought to unlock it using DC unlocker but it failed to do so. I tried everything but it could not help and have error 37 and others.
So kindly refund me. I m planning to give my phone to huawei repair center.
