AC Question

Current situation:
My phone turns on, for some time it shows a black screen with word HTC in the middle, then it shows the bootloader page. But there is no option such as recovery, fastboot, etc. Please see the screen shot here: http ://i65.tinypic. com /28ica39.jpg (remove spaces, sorry I cannot post links in the forum yet)
the vol.up and down keys do nothing. Selecting RUU with power button does nothing. I can push and hold power button to shut down.

Is it bricked?!!! :-s

What happened:
I have(had?!) an HTC One M7, s-on, rooted, stock-rom, TWRP recovery, hboot 1.61.0000.
I was trying to un-root my phone, I did the followings:
1. Booted into bootloader, fast boot and run "fastboot oem lock"
It worked fine, phone restarted in the bootloader and it said "re-blocked"
2.I ran the command "fastboot oem rebootRUU "
It took some time, but eventually, the phone restarted automatically.

since then I am stuck in that screen (see the screenshot above)

3. when I run the command "fastboot flash zip firmware.zip", I get the following result in the command terminal:

target reported max download size of 1514139648 bytes
sending 'zip' (44368 KB)...
OKAY [ 2.737s]
writing 'zip'...

(bootloader) checking model ID...
(bootloader) checking custom ID...
(bootloader) checking main version...
FAILED (remote: 43 main version check fail)
finished. total time: 8.585s


and in the phone screen it says:
"Main version is older!
Update Fail"

the Firmware.zip that I am trying to flash is the one I extracted from the latest OTA that I received from the carrier.

What should I do? Is it a (easy) solution to get over this and unroot my phone?
if no, I just want to forget about unrooting, and get back to normal! Have my phone working!

any help is highly appreciated.
 
[solved] almost!

Good news: It was not bricked
Bad news: I could not unroot yet.

So, after several attempts I could fastboot and unlock the phone again. Have TWRP recovery running, and the phone is back to normal (rooted and working)

The question is how to unroot a S-on, hboot 1.61 HTC One M7 ?
