Stuck at 4G LTE screen after zip update

[iCloud]

I was on 4.0.3 and I flashed the zip through AromRa recovery. Had not installed SU, bootloader was unlocked and S-on.
Now, when booting up, its stuck at the 4G screen.
The update was the OTA update released to update radios to Global. THIS

It didn't gave any error at all, it said "Reboot to complete installation or update". But when I clicked the reboot option, I saw a line saying something like "Can't write....." then the screen went off and it rebooted. This line was not there, or atleast not visible before I clicked the reboot option.

I am new to rezound and android, so please let me know what I can do. I wasn't able to get a nandroid backup before doing this, had no ext. SD card.

All I did before flashing the zip was flashing the custom recovery. Nothing else. No SU or anything else.

Attempt
Locked the bootloader and I flashed the RUU 4.03.605.2
Here's what comes in cmd:
sending....
OKAY
writing
<bootloader>adopting sig ....
<bootloader>checking sig
failed <remote: not allowed>
finished

After rebooting, it gets stuck on the white HTC screen.

Any help pleaes?

Try a factory reset from boot loader.
