I purchased a second hand One M8 which had CyanogenMod installed on it. My aim was to revert it to stock (either on O2 UK or standard HTC ROM) with the abillity to get OTA updates.
I checked the CID (O2__001) and got a stock recovery image and nandroid backup for it. I then used fastboot to flash TWRP as the recovery image, and used that to restore the nandroid backup. That worked fine and it was working with the O2 ROM, so I flashed the stock recovery image as well.
After this it prompted for an OTA update so I thought all was going well. I installed the update and that all worked as expected until it booted up. All the functionality is there, but the Wifi won't turn on at all. If I tap the option to turn it on, it just hangs in the "off" position. It's the same whether I do it through the settings menu or from notification bar. I tried doing a factory reset but it makes no difference. It's very frustrating because other than this, everything is working the way I would like to.
What could cause the Wifi to stop working after an OTA update?
