[HTC 10 Questions & Answers] intheloft:
Hi

I've had my HTC 10 for about 2 months now with no problems. I've been running leedroid's rom and was running Nougat when this problem started. (I'd been running this particular version for a few weeks with 0 problems before this suddenly happened)

On 31st December in the morning I checked my phone to see it had no signal, I thought nothing of it, turned flight mode on and off and the signal came back again. Not long after (within 30 minutes) this happened again. After this happened a few times I rebooted the phone to see if that would solve the problem.

It kept happening so I flashed the latest version from leedroid.

Nothing changed, so I did a clean wipe and re-installed.

The problem was still there so now I was thinking maybe it's a problem with Nougat running on older firmware, so I wiped and installed Marshmellow which also didn't fix it.

I went S-OFF with sunshine and updated the firmware to 2.28.401.9 and still the problem was there.

I've since tried many combinations of roms and firmware, I've even ran a few RUUs with no luck!

I've read that there can be a problem with the radio if the system isn't encrypted however I've always selected "force encryption" in the aroma installer for leedroid and have checked in the storage menu in the settings within android to confirm that the encrypted item is selected and greyed out.

The weird thing is, I've discovered that I can still get data over the mobile network (if it shows I have a signal), just not SMS or phone calls. Although.... I did manage to make one call when I thought I'd fixed it, but after I hung up the signal dropped again.

I've spent the last 2 days pulling my hair out trying to get this thing to work again and now I've got no idea what to try. If any of you have seen this or have any ideas of what to do to get it working again I'd be very very grateful!

I'll copy in the results from fastboot getvar all so you have some more info about the device.
