i have an 820 GO live. was working perfectly, until i did an update. now when i turn it on, it starts up fine BUT after about 10/20 seconds the screen goes grey. it stays that way for about 30secs/1minute then it shuts itself down, about 10 seconds later it comes back on and starts the whole procedure again. it keeps repeating this over and over again. HELP. I have tried using a different computer to try the update again but to no avail.
