I have a Pegasus R6 and somehow it updated to firmware Bios 5.04.000.62 which is not compatible with my unit. I have tried to manually upgrade (downgrade) to Bios 5.04.000.61, but everytime I try I get an error issue. How can I replace the 5.04.000.62 with 5.04.000.61? Thanks in advance!
Firmware Update (Bios 5.04.000.62) to (Bios 5.04.000.61) Promise4.04.000.39 (C04)

Hi Steve,
I am not sure if you can downgrade the firmware. You can try it in Terminal but not sure if that would work.
Open MAC terminal and then type promiseutil. Then type ptiflash -f (drag&drop the firmware file) and hit return.
Since you have mentioned that current firmware doesnt work, let us know what is the issue, and create a case at https://support.promise.com/ we will help you .
Thanks !
