Hope that someone can help me.
I managed to get my hands on another DHD in amazing condition, looks new, so that I could sell my original handset.
So I did the same as before unlocked the phone by HTC Dev, installed TWRP and then Cm11, fastboot flashed the boot.img file and it was alive.
After running through the set up, the phone the rebooted by itself (Weird I thought), then after about 10 mins it rebooted again and the phone reboots itself all the time.
There is no pattern that I have found, no set time limit to the reboots or particular apps that cause it to reboot??
I have also tried different Rom's and it still has the same issue.
Anyone got any ideas?
