Hello
Recently i bought used Xiaomi Poco X5 which had broken screen. After changing screen everything work well but I don't have signal and no service on my phone so WIFI working correctly but LTE is not working. There is no damage on my motheroboard so I don't know why phone has no signal. Which part I had to change?

Hopefully someone will be able to help you, but keep in mind it is a custom ROM forum, not a lot of people will have this level of hardware knowledge.

Yes, I also experienced very poor mobile data connection on poco x5, official hyper os has way better mobile data

The problem may be with the antenna or SIM card tray. Check that the SIM card is inserted correctly and try it in another phone to rule out a SIM card issue. If the SIM card works in another location, the problem may be with the phone's cellular antenna, which may have been damaged during the screen replacement. Check and, if necessary, replace the antenna or the coaxial cable connecting it to the motherboard. If that doesn't work, the RF module may need attention.
