Installed Android 12 and now the phone will not connect to 5G or 4G. Tried to roll back to Android 11 but when I went into fastboot the laptop (an Asus laptop by the way) didn't seem to recognize that the phone had been plugged in and when I tried to run the flashall_AFT.cmd script anyway it just failed. Just saw other comment from 15 July - yep I have T-Mobile USA.
