OnePlus 7T Pro Mclaren Andoid 11 uodate sim oroblems
Sinc the update yesterday I've had times where the phone doesn't read sim card or connect to Wifi. It's frustrating because I never had a problem with the phone until the update. It's only been a day...

Have you tried removing the SIM, cleaning it with a little Isopropyl, and then putting it back in? Sometimes the contacts start to get a little tarnished over time. There is an MSM Tool from OnePlus that can restore the devices firmware to an earlier build, if no troubleshooting solves the issue. If you can get the WiFi working, perhaps check for another update to see if there is an update to fix the issues you are having. Otherwise, using the MSM Toon will return your device to an earlier firmware while completely wiping the device.
Hi, is this tool in the Play Store? I'm still having this issue on and off since the update. I've cleaned the sim card, what's strange is that the wifi gets affected also and it can't be turned on.
if im thinking correctly it would be on the One Plus site itself. syaoran can walk you through it a bit on where to locate it and the pros/cons of doing it.
