After updating to 5.04.0000.61 , my R6 doesnt mount my pass thru disks , mounts the RAID 0 array but it beach balls my Intel Mac , Crashes my M1 and the Promise Utility hangs. Is there a way to revert it back to the previous firmware? My other R6 on a much older firmware works fine with both intel or M1

Hi Jeremy,
This is the first issue reported for 5.04.0000.61. But you should be able to reflash an earlier version, probably you should use the same version as your other Pegasus.
Please try this, eject any Volumes that are mounted, remove the thunderbolt and power cable and unseat all the hard drives, don't remove them just slide them out an inch or so. Then reinsert the power cable and thunderbolt cable and let the Pegasus boot diskless.
The promiseutil is the best way to flash the firmware.

To add the firmware file name just drag the file from the finder and drop it into the terminal.
I used 5.04.00000.57 as an example, use whatever firmare works in the other unit.
After the firmware downdate you can power off the Pegaus and reinsert the drives.

Hi Jeremy,
Go to the promise webpage at www.promise.com, click support, then click download center.
Select Legacy, and select your product from the pulldown menus.
The firmware can be downloaded from the firmware section.
