Hello, did you solve the problem with MGX92LL? I have exactly the same model, and the problem is one in one, there is no true dump unfortunately

Hi guys, I got a dump from ebay, it works fine on the A1502 2.8 mgx92 model. The serial number is missing, ME is clean. But I can not register my serial number, a flash drive with a blank board serializer hangs at boot time, tried 3 versions
