[Q] TWRP and HBOOT topic

I have not been able to update to TWRP 2.8.5.0 from 2.8.0.3, every time I end up hanging in entering recovering in the white boot screen. I have tried fastboot and the RUU method, I always end up reinstalling the 2.8.0.3 TWRP to get recovery back. I checked the firmware everything is up to date but hboot currently on 16 latest is 19. Question could my hboot being out of date cause the update problem and can I just flash the hboot alone?
