Cannot access recovery after attempted TWRP update, noob to HTC Devices

I've got an HTC One M9 (Rogers) that I've rooted and installed CM13 (13.0-20160221-nightly-himaul). I'm reasonably experienced with custom ROMs and such having played with all of this stuff on several Samsung devices (Captivate, Galaxy Nexus, SGS3), but this is my first go on an HTC device and first time running TWRP as opposed to Clockworkmod. I attempted to update my TWRP from 2.8.4 to 3.0.0-2 by booting to recovery. Not sure how and where I went wrong in that process but I can no longer boot to recovery, the phone starts up just fine and is usable. I can still access download mode and the bootloader, device is S-on (and has never been s-off). I have since attempted to reinstall TWRP via ADB commands as per the below post. The flash seems to take, no errors but still I'm unable to access recovery. I'm at somewhat of a loss as to what if anything I can try next.
