Supermicro X10SLM-F: Applied firmware and bios out of order, now stuck in reboot loop. Help!

I bought a Supermicro X10SLM-F off ebay and it had a very old firmware and bios. I mistakenly updated the firmware first through IPMI, then tried to update bios. I rebooted and am caught in an infinite reboot loop, it never makes it to even the BIOS options, nor letting me boot from USB.
The problem is that once the bios got to 100% it was stuck there. Doing some research, I found this Supermicro FAQ which says this about a reboot

This [reboot loop] is due to using a newer IPMI firmware with an older Bios. The Bios needs to be updated first. Please either disable the IPMI by setting the JPB1 jumper to pins 2-3 and then update the Bios using a bootable USB flash drive, then enable the IPMI be setting the JPB1 jumper to pins 1-2. Or if you have the OOB remote Bios update license, shut down the system and update the Bios using the IPMI remote interface.
I looked up my manual, and it says to change jumper JPB1 from 1-2 to 2-3 to disable IPMI/BMC. The schematic shows it's location:

Problem is, my motherboard doesn't even have this jumper.. it's missing!

Looking again at the manual, the photo they provide even shows that it's missing which matches my board, so my board isn't an anomaly or defective:

How the heck do I solve this? My server is dead in the water.

If you can get to the IPMI interface you can flash the BIOS from there if you have a license to do so.

I think I got mine from a different place for a bit cheaper.
That's how I originally attempted the bios update. I did it out of order as I mentioned.. I did firmware first, then bios update which was a mistake because apparently the firmware update changed the way it upgrades the BIOS and incompatible with older BIOS.

Since you just need to short pin 2 to 3, I would try two ideas: 1 - try a generous line of graphite pencil lead between the two solder points, or 2 - break out a solder iron and solder a short piece of wire between the two points... and cut it off once done.

I am surprised you can't use the update via IPMI with a license though... I thought that should work for you.

Okay, I got this resolved!

I shorted Pin 2 and 3 using a flat head screw driver while I booted. I was able to get past POST and boot to my USB Key that was prepped to run DOS using Rufus.
I then ran the bios update from the DOS prompt using the AMI.bat file.

I rebooted, and it continually looped again. I shorted the pins again, got past POST and then got into bios and did a "reset". Rebooted and everything worked, no more looping.

I then went back into bios and setup my bios options how i like and i'm set.

When you updated your BIOS, did you clear all check boxes referring to keeping settings? i.e. did you completely wipe your BIOS settings to default during the update process?

If not that may have been your issue all along, as in the end what corrected your error was a BIOS reset to default.

If you had settings in use that the new BIOS changed, attempting to maintain them during update could easily cause your symptoms.
