Hello Rewa, just to ask you.. when you program new NAND chip – it is necessary program also the logic board number to new one ? I thought that only serial number is enough. Thanks for reply

Is it okay if I just reball the NAND instead of replacing it? Don't have the right equipment to write to new NAND

My iphone 6 worked great for 4 months. Now from last week it started restarting itself. First, it rebooted once a day. But now it just keeps restarting until battery dies. I've tried resetting, completely restoring it. Didn't work. But it works amazingly perfect while plugged in. Never restarts while charger is plugged in. What might be the issue? Kindly reply.
