When I look at the BIOS release notes for the current and previous BIOS releases, I do not see any information that indicates that you cannot go back to an earlier version.
Usually that is indicated in the release notes if you cannot.

Unfortunately, I wouldn't know.
If that is the error you are getting, perhaps you can't go back then.
If you look at this model series for example, it is written that once you update to a certain version, you cannot go back.

As far as I know, yes.
Have you tried the F10 setup BIOS method to flash the BIOS?
Startup Menu/Computer Setup BIOS Flashing
The HP Workstation supported by this Softpaq provides a BIOS upgrade option through Computer setup (F10) using the “Flash System ROM” feature. Reboot the workstation and press the Escape key to display the Startup Menu. Use the arrow keys to select Utilities, and then select the Flash System ROM option. Alternatively, reboot the workstation and press F10 to enter Computer Setup. In the File menu, select the “Flash System ROM” item. Either method requires that a removable storage device be present (typically a USB flash storage device) containing the BIOS binary image file in the root folder. The binary image file can be found in the DOS Flash folder of this SoftPaq and is named XXX_MMmm.bin where "XXX" is the abbreviated BIOS family (e.g. "J51"), "MM" is the major version number, and "mm" is the minor version number. If a BIOS Setup password has been set, the password will be required before being able to access the "Flash System ROM" menu. The user is notified when the process is completed. The new BIOS code will not take effect until the workstation is restarted.
When you run the file, an info page opens. Follow the instructions under the above section.
Get a USB flash drive. Format it with the FAT32 file system.
Copy the file contents from the DOS flash folder to the flash drive. Just the files, not the folder.
Restart the PC, press the ESC key to get the menu of options.
Select the F10 Setup option and press the enter key.
Select the File tab>Flash System ROM command.
Select the USB flash drive.
The PC should 'see' the files on the flash drive.
Follow the onscreen instructions to update the BIOS.
If you still get an error, than it must be impossible to go back to an earlier version.
