Welcome to another Rabbit hole! I have just given up on the same repair. I think if I restored it I would have been faced with the unable to activate so I didn’t try.

On other phones I found that the IMEI stays in settings until it is restored than there is usually no IMEI and the unable to activate message is displayed.

You will need to remove baseband and check for oxidised pads which I have encountered once before. If you do remove baseband I suggest doing a bottom board swap which includes baseband, eeprom and the NFC IC’s. That way you have ruled out everything and can conclude it is a faulty baseband.

Hahahaha, I've started to hate these 8-X boards especially QUALCOMM, I've got three 8s and two x's for no IMEI all QUALCOMM in these 3 days.

@iammyron07 The X’s are not that bad as I said just do a bottom board swap with an iCloud locked one. It doesn’t take that long and you can than put it in a board fixture to check. If still no IMEI don’t go any further with the repair.

Yeah, Bottom board swap can be done but if it doesn't get fixed even after that, the phone wont activate so the customer will create issues that i gave you a phone on homescreen and now i cant even use it so im a bit scared to take the risk. Customers here in India are pretty different especially in my state. So i would probably return this as a no fix?
