6.10.3 bricked two RN516 units
Recently, we upgraded the firmware on our thwo ReadyNAS 516s to 6.10.3. We used the automatic update (prompted on login), and updated from 6.10.2. The NAS rebooted and worked fine until a couple days later, when they were scheduled to reboot by schedule (once weekly reboots). Following the reboots, both NAS units now read mount_block_root +e25 on the front panel. USB recovery does not work; we are able to get the panel on occasion to indicate booting from USB, but the thumb drives prepared with the USB Recovery Tool (we have tried three different thumb drive models) do not do anything--the panel then reverts to Booting... and gives the same error as above.
Is there any way we can either get the NAS to boot, or recover the data from the RAID arrays (Flex-RAID) in another unit (e.g., a Synology chassis)? The files are not super valuable but would be nice to have.
Thanks!

What apps were you running on the two NAS?
Try removing all the disks from one NAS (labeling by slot). When you power it up, do you see a "no disks" status on the LCD?
FWIW, I think USB recovery is the right step here. The system can be fussy about what USB drives it will accept. Generally smaller/older ones work better.
Ideally, use a USB drive with an access LED so you will know if it's even being accessed.
While the legacy NAS are quite particular about the USB drive used, I've found the newer ones (and that includes my 516) to be less so, though a USB3 drive will typically give problems.
