Help! RN426 FW update stuck: could not mount boot flash
I have had this unit for a while. It has been fine.
Noticed there was a firmware update. Existing FW was 6.10.4 Hotfix (I think). Update is to 6.10.5.
Ran update through the admin UI. Rebooted. Now the LCD says "ERR: Could not mount boot flash" and the fans are running strong.
Cannot connect through RAIDar or the usual IP address. It does appear in RAIDar, however, with status TFTP_REQ and the updated 6.10.5 firmware. But no button to go to Admin Page.
I do have an 8TB external USB drive attached for backups, but I'd prefer not to reset and start over if it can be avoided. Any tips for things to try? I'll just leave it sitting there for the moment...
The next thing to try is to power cycle it.
If the flash has actually failed, then you'll need a new NAS (hopefully not the case!). So you might also want to check your warranty status (warranty is 5 years for a new purchase from an authorized reseller).

It's been so reliable for so long, I had forgotten how to switch it off!
Booting... updating FW...

Great.
There is a bug in 6.10.5 - some folks are experiencing a login loop when they try to access the admin web ui. So you should definitely double-check that you can log in to that.
FWIW, I'm not experiencing this problem, so it's not affecting everybody. But it has been quite painful for the folks who are.
