[Q] process system isn't responding
So i've tried to unroot my device and reinstall a stock rom but the device says "process system isnt responding". I have twrp 2.6.3 recovery installed so i've wiped cache, wiped dalvik cache, wiped system, and then installed a stock ruu zip files from htc1guru.com.
Any ideas? The install returns sucessful but still stuck. When i boot into bootloader there is nothing next to "os". Does this suggest that the install infact failed?
The phone is out of warranty so i'm stuck with it.
