Upgrading from 4.4.1 -> 5.1.0; Mini hung during firmware update  

RE: Upgrading from 4.4.1 -> 5.1.0; Mini hung during firmware update

I was able to roll back to 4.4.1 but the self-test fails while trying to test the fans. It appears to crash and then I get a WATCHDOG error. Restarting and skipping the self test gets me to extruding plastic for a filament load. I tried four times and just gave up on the HW test.

I'll be testing prints for the next few days to make sure I'm back to a working printer; goes without saying I lost my settings on the reset.

5.1.0 firmware update hasn't gone as smoothly as past firmware updates. I have to say I'm a bit disappointed. I may try again after I'm back to reliable printing, but I'll need to shift over to our Voron for our Etsy store prints in the mean time.

Use a different USB stick and reset to factory settings.  It tries to write to the USB stick when errors happen and if it can't, bad stuff.  Every weird thing I have seen has been due to a bad USB stick.

I was able to install 5.1.0 but having issues.

Changing the USB thumb drive and removing all the files except the en_cs.bbf allowed the install to move forward.

However, the hardware test failed the nozzle heater, but passed when testing heaters and fans individually.

The MINI halts at 2 or 3 layers into the job complaining an issue with the fan even though it passes the hardware test. I just printed on the MINI a day ago with no issues on firmware v4.4.1. I'm downgrading until these issues get sorted - giving up for the time being. 🙁
