How did you change the PCB? Got it changed from the service center or did it yourself? If you did it yourself , where did you obtain the PCB. Seems like your IMEI is missing , restore IMEI and it should work.

did it self, no warranty.

the PCB have i buyed at AliExpress, 5 USD with Shipping..

how can i restore the IMEI? never did this before.

you clearly dont know what youre talking about. You changed the board thats on the lower part of the phone, yet you implied that you changed the motherboard.

Your imei isnt lost, dont worry about that. Check the antenna cables, theyre pretty hard to get off and on the connectors, especially for someone whos doing it for the first time (they should snap in with a lot of force). If that doesnt work then the board that you changed is bad. I have bought many parts of off aliexpress, but not a single charging/antenna/speaker board has ever worked for me.

yes, ok, I do not know much about that. That's why I asked here.

If someone tells me that my IMEI has been lost by the exchange, I assume that this answer is probably correct.

As I said after the exchange, everything works, except for mobile. WiFi, Bluetooth, etc. works

I then built it back on that old PCB and my mobile network is back, but there notification LED stopped working and the lower/Button speaker is without function.
