1) clear htc backup data under settings APPs
2) clear play services data under settings APPs for those who use Google account to backup (maybe also dropbox for those on dropbox)
3) rename phone
After those steps they set up HTC backup again and it worked.
Some of them wiped cache as well prior to setting up backup again, but doesn't make sense for me in this case.
