Help Urgent: Phone keep looping on start up screen after official update

HI
As title said, I accepted the official update from HTC and now my phone won't start.
All I know is I have S-ON and I don't want to do factory wipe.
I did try wipe cache partition multiple times.

here is the info from download mode:
