The problem from the photo of the service mode that you posted is evident in some failures imei certi fail, it means that cert and imei is damaged, even if you wrote that from the phone's keypad * # 06 #, - imei is ok! and appears the imei is damaged, to repair the cert and imei via box is impossible having the g930t the qualcomm processor is not supported, you can only write imei original rooting the phone, but if you do not have a backup of the cert and imei original, you can not do nothing, the only way is to get it done remotely for a fee by changing imei.

By writing the qcn to g935t you repaired the mipi but damaged the cert and imei, but the problem is upstream, before unblocking the network with z3x via credit server, was the mipi in place or damaged?

I think the mipi was in place before I unblocked the network with z3x because otherwise the unlocking operation in my opinion gave an error and failed and was damaged after you unlocked the phone, you are not the only one who is success this there are many posts on forums in various sections of the forum that had this problem.
