Crashing Nova Launcher & UCCW

Hey Guys,

I've got a Nexus 7 (2013) WiFi version which has been rooted and had Timurs kernel installed.

I've installed Nova Launcher and UCCW. I've used UCCW to create a widget but each time I select the UCCW widget and try and drop it on the launcher screen the whole tablet crashes and reboots, I've forced stop and cleared data on both the launchers and its still not working.

If I use a system widget or other widget like 1weather etc then its fine but any of the UCCW widgets fails :(

Can anyone help me please?

Cyanogen OS 12.1 occasionally crashing

So an issue I've had since moving from Oxygen to Cyanogen is that every now and again the system will lock up, and the only way to get it back is to press and hold the power button until it does a forced restart. Today it did it while I was paying for something using Android Pay and it asked me to enter my lock code. II drew my pattern and the system froze.

It's fine this before when using the camera, playing games, etc. It's pretty random.

I've also been having Bluetooth issues, but that's another story.

Xperia L crashing randomly

My Xperia L started to do weird stuff about a month ago. Suddenly all apps would crash (unfortunately.. has stopped working). I have to pull out the battery to fix it and sometimes it wont start (bootloop or stuck on sony logo). I did hard reset, flashed stock ftf but nothing works. Sometimes it does this when it is under load and sometimes completely random. I bought a phone with a cracked screen after i bricked mine and it had a battery drain problem. After taking it to a local reapir shop they've managed to fix it but they told me they had to resolder something because of water damage. Is it possible this problem to be the result of water damage also?
