I guess I am not doing it right..
I guess I am not doing this right... I followed below steps and phone goes in bootloop from home screen. My phone hboot shows 5.12.502.2. I am using openrecovery-twrp-2.6.3.3-m7
All MD5 are matching.
1. Downloaded Nandroid backup from here: http://www.androidfilehost.com/?fid=23501681358543596
MD5: b01ad6da065b19c7aff36f77724a5b74
2. Extracted to PC at 'HTCOne-32GB-ATT-5.12.502.2-TWRP-stock-unrooted' and copied to /sdcard/TWRP/BACKUPS/serialnum/HTCOne-32GB-ATT-5.12.502.2-TWRP-stock-unrooted
3. Restored the nandroid without any errors.
4. Rebooted the phone --> Got the home screen and then phone rebooted
5. I allowed the phone to reboot for 4-5 times but no luck.
6. Went to TWRP and did factory reset --> rebooted the phone and no luck.
7. Now, went to fastboot usb mode and did fastboot flash recovery 5.12.502.2.recovery.img then fastboot erase cache and fastboot reboot
I still see the same result. I am slightly confused if the 5.12.502.2.firmware.zip is needed and if so at what point it needs to be applied. I am assuming steps are
1. lock bootloader with fastboot oem lock
2. fastboot oem rebootRUU
3. fastboot flash zip 5.12.502.2.firmware.zip
Edit: I have also uploaded a Guru_Reset of this if anyone is interested (Thanks to @crushalot)

Extract zip, copy 'HTCOne-32GB-ATT-5.12.502.2-TWRP-stock-unrooted' folder to /sdcard/TWRP/BACKUPS//HTCOne-32GB-ATT-5.12.502.2-TWRP-stock-unrooted
For complete stock Say no to installing Root when exiting TWRP and Flash the Stock Recovery
It's also recommended to Factory Reset in TWRP after Restoring the Firmware

Be Very Careful with the firmware posted below, I actually put my HTC One into QHSUSB_DLOAD Flashing this. I was able to fix it (Thanks to dexter93) but be very careful and do not flash a 3.xx.502.x firmware with the one posted below !!
