Restore from U-boot Test

I used U-Boot Test to backup the Ubiquiti ver 5.5.6 XM firmware on my NanoBridge M5 before loading the AREDN firmware.
I'd like to go back to the Ubiquiti version for some testing.
While I found the backup button on U-boot OK, I haven't found a Restore button.
Now that I have the AREDN set on the M5, can I go back?
It doesn't have to be the version that U-boot created, I just thought that may be the easiest / safest approach.
I tried the Windows 10 web firmware update to the M5, but it won't accept the Ubiquiti bin file.
Or, how do I restore from the U-boot Test backup files?

You just need to do the TFTP
You just need to do the TFTP load of the Ubiquiti AirOS firmware.   No special utility needed.

Thanks for the reply.
And roger on the tftp.
Wondering if I can tftp the U-boot Test backup files: CFG.backup, EEPROM.backup, U-BOOT.backup, and U-BOOT-ENV.backup.
And do I have to rename those files or create a bin?
Or, should I just tftp one of the version 5 Ubiquiti bin files?

The files from the U-Boot
The files from the U-Boot test utility, are not made to be restored with tftp.  You don't need them.
Just TFTP the UBNT v5.5 bin file.

U-boot Test backup files
So... are you saying there is no purpose to backing the U-boot Test backups?

Correct.  The function was
Correct.  The function was put there just in case when we were researching the issue with the newer U-Boot.  After we understood the problem, it was deemed not necessary to do that backup as the configuration partition was not being destroyed.   It doesn't hurt to back them up and those partitions in theory, could be restored via the commandline, but, we haven't seen a situation that dictated that to date.
