Request for E9+ OTA update at rooted + TWRP recovery flashed phone

my E9+ is running with 1.41.7070.12 with unlocked, s-on, TWRP recovery and rooted. I currently keep on receiving 1.45.707.5 ota and I wish to update it without losing my current data. please advise what is the correct procedure?

I tried to download recovery_hTC_Asia_WWE_1.45.707.5.zip and flash recovery img, the phone manage to run and do recovery but immediately it show triangle and exclamation mark (!).

Thanks.
