Could you please help me.
Namely i have HP 6915 wm5, and my phone make restart himself, sometimes once, sometimes 10-15 times, than work properly, and than restart again and again.
I make a master reset but there is no result, i was try to replace the batery, but i still have the same problem.
Maybe i need to install wm6, could you please tell me where can i find them

Many thanks in advance

The problem could be that the battery cover get loose. Try to put a bussines card between the bat and the cover, what you need to make is to make it tight.
