why did you super cid? what cid is it now. can you put back to original cid?
device has to be completely stock to run ota.
unrooted. (only way i could get unrooted was to format system then restore my 4.3 backup, and flash stock recovery and lockbootloader.
only then would ota work.
restore your original cid, get a backup from your region and restore.
if your cid was o2_102 then can you change it to htc_102. then it may run ota fine.
i have a cwm backup of my t6ul international from vodafone uk if you want it to try.
instal latest cwm recovery. think its 220.127.116.11
make a backup of you current rom first. then download my backup here and uncompress to external sdcard https://www.dropbox.com/s/pj9mds5lal...kmodbackup.rar
format your system, data, and restore my cwm backup.
boot device once and run setup wizard.
flash stock recovery and lock bootloader by scotty123's method (NOT RE-LOCK, ota will not work)
now ota should work.
this has helped many others
