Hi Everyone
Okay here is how I solved my problem so hope it helps someone.
I got my XE about a month ago as a replacement for my windows phone. I had a 32GB card in there which was about half filled with apps. I am assuming that as a we are all on a forum a number of us are quite hard core users installing and un-installing apps frequently.
Now what I remember doing the night before last, was going through the file system of the memory card when it was connected to my PC and noticing that a lot of the data was not uninstalled very cleanly, so I stated deleting old data folders as 10GB left on the card did not seem like enough space!
I remember deleting a folder for Worms as I was sure that I had uninstalled it. Then last night I charged my battery and wanted to do the same with my spare so swapped them. This was when I noticed the re-starting problem! It was in a continuous loop!
After reading some threads here I was
just about to do a factory reset when I thought that I would try the phone without the data card.
The phone stopped restarting.
So obviously It was some type of software error which had kicked in because I had restarted my phone when I changed the battery. After going through the 100+ apps and removing a few, I saw the Worms shortcut and remembered that I had deleted the folder! So after uninstalling this the re-starting stopped!
So if anyone has made any filesystem changes look to this area, as I
refused to wipe either my phone or data card!
Good luck.
