Unhappy [Q] HTC Dual software got tampered

Hi Friends,

I have HTC One dual, I unlocked it from htcdev to get android latest updates.

When I have seen Android 4.4 update for my device, I tried to install it, but due to some unknown problem, device was getting rebooted again and again. So I selected option factory reset, but this also not worked bcoz device got unlocked.

Later I have tried to push some .img files on to device, finally the device got tampered, unlocked.

Please suggest me best solution to get android back on the device.

atleast suggets me to install any software in that device.

Thanks,
Anil
