HTC One M8 - No Signal - Airplane mode turning off...

[crawley_87]

Hi,

My M8 isn't receiving signal, everything else works fine, I checked the sim card in another phone and it works.

I did notice that airplane mode is stuck tuning off. Any ideas how I can fix this?

I rooted the phone (very new to rooting) but didn't go so far as to flash a mod. I unrooted the phone back to stock. It was fine for a couple of weeks, then one day randomly lost signal.

I've tried factory resetting but no luck.

Thanks

It's still under warranty - bring it back.

I did message htc and they said Unlocking boot loader invalidates the manufacturer's warranty
