Stuck on Google logo instead of recovery

Re: Stuck on Google Splash Screen Instead of Going to Recovery Mode Instead of necroing an older thread I thought it be prudent to start one new.

Downgraded the ROM on my Pixel 3a to the required version easypeasy using Chrome (browser).
Followed the instructions on the UT installer, everytime instead of going into Halium recovery, just get the Google logo.

So reinstalled the stock ROM following the instructions:
Force flash all partitions - ticked
Disable verification - ticked
Disable verity - ticked

Using 0.8.8 and 0.8.9, both times stuck at the Google logo.

Instead of reinstalling the stock ROM I ran the UT installer 0.8.9 again and ticked the wipe data box and this time it went through.

I think the previous instructions should go on the devices page as I missed it and only found it coming here.
