After a T-Mobile update to Android 10 One UI 2.0 my phone behaved oddly. It frequently lost data and network connection, whilst playing PUBG froze and restarted itself. I thought maybe it was because I was being a but abusive to the phone but then I realized my phone literally has IMEI status as unknown and now I cant connect to T-Mobile services at all. I got a new SIM card thinking a two year old SIM might be faulty ans the problems persisted. That didnt work so I cleared cache. Then factory resetted. Then cleared cache again and reset again. But to no avail . So now I have made an XDA account because I dont know what to do with my phone. Is it possible to restore my phone's IMEI? If so how?
P.S I did not tinker with this phone in anyway whatsoever like rooting and such.
Thank you XDA community.
