I know how upsetting this can be. See posts 3, 5, 7 and 8 as regards to what worked for me. It's been a while since I had the problem, thus I don't recall all the details, but I believe I had to follow the instructions in the Maintenance Manual exactly. I have since done one more eUFI update using the CD iso and it went OK. (I'm a little scared to try another one since you have reported this problem, though....)
As far as an earlier version, if you scroll down to the 'Addidtional Information' section of the following web page, the version from July '18 appears to still be available. That is the one I last installed successfully and am running. (Note that Lenovo's web pages seem to be very laggy to load at the moment...) If you can't get the file there let me know. I have a copy and we can try to find a way to get it to you.

I have the M92P Tiny desktop and was able to recover from a failed BIOS update using a USB drive.
After trying all the solutions from multiple threads on this forum, this is what worked for me:
Download Rufus and format USB drive with FreeDOS
Download ISO from this link: https://support.lenovo.com/us/en/solutions/ht077504
Extract ISO to USB drive - overwrite ALL files
Move CMOS jumper from 1-2 to 2-3
Disconnect HDD - leave the speaker connected
Insert USB drive into USB 2.0 port on the back (the black colored USB port, not the blue ones, labeled 5)
Power on M92P
You should hear two loud beeps, followed by two (fainter) beeps that repeat
A screen should be displayed that the BIOS is being updated
The M92P will auto power down when completed
Disconnect power, move jumper back, reconnect everything
I also did the above again, except with the newest BIOS version, and everything worked great!
Thank you to all for the assitance from these forums.
Thanks for this solution. Saved me from having to buy a new motherboard or going to buy some blank CDs. Created an account on these forums just to say thanks.

After upgrading a perfectly working M92p Tiny (type 3237) from Windows 7 to Windows 10, I went to the Lenovo driver portal for the latest drivers, all of which installed through Windows except the BIOS which kept failing without an error code. I found the ht077504 predecessor to this post, which led me to download the 9SJ979USA M92p BIOS ISO and burn to a CD. I opened the Tiny, moved the CMOS reset jumper, unplugged the hard drive, plugged the CD drive into the only black USB connector in the back and plugged in the VGA monitor (no keyboard or mouse connected). When I powered it up, the VGA screen lit, I watched the firmware get copied from 0 to 100 percent and the computer shut off when finished. I unplugged the CD drive, replaced the disk drive cable, moved the CMOS jumper back and connected the keyboard and mouse. When I plugged in the power, the fan and power light immediately started, but nothing else was working (mouse was not lit, no keyboard response, VGA light stayed amber).
I found and read this entire post and believe I have tried every combination of what is here, including locating and trying the same CD procedure with the newer 9SJ99CUSA M92p BIOS, and using RUFUS to FreeDOS format a 4 Gb USB stick and WinRAR to extracted and copy the files from both the 9SJ979USA and 9SJ99CUSA ISO files (one first, then the other), with the CD drive or USB plugged into the black USB connector on the back, the disk drive detached and the CMOS jumper in the reset position. In every attempt, regardless of whether the CD or USB stick is plugged into the black USB connector, when I connect the power, the power light immediately lights and fan spins, the CD or USB stick blinks a few times, then absolutely nothing happens (while waiting up to 5 minutes) and the VGA monitor never turns from amber to green. The only other sign of life is if the CMOS jumper is in the reset position (I believe I’m correct as there is no 1,2,3 markings on the system board) and everything is disconnected (no monitor, keyboard, mouse, disk drive or boot device), the M92p sounds two soft beeps every five seconds.
Everyone before me seems to have found a way to resuscitate their computer, so I am hoping someone has a suggestion for me. Thanks in advance.

I have tried to update my M73 10B5's update via the ISO to USB stick method.
This semi-bricked my machine. the first time I tried this, I got something like "Disk DOS booting", then the monitor went to standby and I heard two beeps.
I (stupidly) rebooted the computer at that time.
Since then, I have had either of the following happen:
I have tried the following:
This all has had no effect at all, I still have no display at all and have the choice of either 2 beeps with a BIOS update medium or 2 beeps, repeating without a BIOS update medium.
I am a bit out of options.
My gut feeling says I should check the RAM, but I don't have a pc that takes (or can donor) DDR3, and I'm not investing the €29 for the cheapest DDR I can get, as then it would be saner to get a raspberry pi 4.
But if anyone has any hints as what I can try, I would be grateful.
