HTC one M8 New OTA update -boot loop issue

I recently got an OTA update and since then my phone has been on a boot loop, when the phone starts every time it says "Android is updating.." then takes me to the home screen and within 10 secs the phone reboots.
This has been happening from last 2 days and I cant seem to find any solution to this.

The phone has 100% official status, only developer options turned on with the USB debugging on, which has been on for last couple of months I guess.

When I get to Recovery at the bottom it shows this error messages:
E:missing bitmap oem_unlock_bg
(Code -1)
E:missing bitmap oem_unlock_bg_yes
(Code -1)
E:missing bitmap oem_unlock_bg_no
(Code -1)
Write host_mode success
handle_cota_install: No CW files. Skip cw installation.

I even tried factory resetting the phone, but still no luck. My data still won't get erased and the phone lock pattern is intact.

The HBOOT screen looks like this:

**** Software status: official***
*** LOCKED ***

Can anyone please suggest how to get rid of this issue.

Thanks in advance,
