i want to add a european rom in my htc one. I am S-OFF and changed my CID from SPCS_001 to HTC__032. I then downloaded unbranded firmware 3.62.401.1.zip and finally flashed this ROM file Guru_Reset_M7_3.62.401.1. But after it finished when i pressed reboot screen strays in bootloader and cannot reboot to the system. Any ideas?
