I'm new android user and I recently got the HTC one M8 in which I wanted to install the google play edition RUU, I rooted the device, S-off as well and changed the CID number, I used the adb commands to flash the RUU (without taking any backups ), when the phone restarted I was frozen with HTC logo, I could not do anything, the phone is not recognized in adb devices and I don't know what to do next, Pleeeeease help !!
P.S: i tried to install the 5.1 non rooted lollipop !!!
