Bricked SRT6KRMXLT?

[SBKioti]

I upgraded the firmware on my SRT6KRMXLT and now my UPS will not power on.  I just get a red panel alarm, Comm Event: to power off press and hold power button. 

• I am able to get into the NMC via URL, SSH, FTP, and serial so it is not totally bricked. 
• The web page shows the new firmware, so I believe the upgrade process worked.
•  I FTP'ed an older version of the firmware but when I try to run the UPSFWUPDATE command it responds that the UPS must be turned off.  If I try the UPS -c Off command it just fails.
• UPS Status says State: Main input bad., Bypass Out of Range, Discharged, Internal Communication Fault
• Tried the Brain Dead reset several times, no change.

So I am trying to determine if there is a way to trick the UPS to thinking it is turned off so I can manually run the downgrade.  Appreciate any help I can get to avoid having to buy a new UPS.

Thanks

Yeah, I saw that post.  Their problem sounded like the NMC was bricked.  I can get to the NMC fine and upload current and old firmwares.  But on mine when you upload it you have to issue the firmware update command to actually install it, at least that is what I find in documentation.  Maybe I am missing something.

Thanks,

Hi Steve,

In that thread I call out the specific steps that must be in place and done. Specifically the firmware must be done directly using the RS-232 -> RJ50 Serial cable.

The options are to try the FUW first and see the results. If that fails the break fix is attaching the USB cable at the same time.

The last method is using X-Modem and follow the APC Technical Manual.
