[Q & A] No service after screen replacement

Yo sup!

I recently replaced my screen and everything works fine except that I don't have any Network signal/baseband/service at all. Now what do I do? Reflash the original V5 ROM and then wipe & reset, and restore to back up, or first wipe & reset and then reflash the original ROM?

If this doesn't work though, how do I check on the motherboard if the antenna or some pins are the problem? Don't really have experience with that..

If someone could help me out I would really appreciate it!

Can you verify is your IMEI still intact?

Settings > About Phone > Status > IMEI Infomation

You get your screen replacement done at Xiaomi service centre or those 3rd party unauthorized shop to get it repair?

I ordered a official screen from Ibuygou, digitizer and touch screen all glued together so I just removed the broken screen carefully, reassembled everything, and the touchscreen works like charm, and so does every other function except the network. I checked the wifi adapt thingies on the motherboard and as far as I could tell, everything was intact there. I do flash my rom a lot so can't it just be a software issue because I attached the new screen and digitizer?

Just trying to tell you how the process went, got any suggestions on how to find out what exactly causes the issue here?

Thanks again bro!

Damn ye I thought something like that was going on. I can just restore to back up right after I followed all of these steps? A dumb question maybe but just want to make sure :)

Appreciate your help!

You need to replace back the same IMEI and baseband before it can receive signal again
