Help with bricked APC UPS SMT1500

(1/7) > >>

PeeJay:
Hi, somehow I've managed to brick my UPS.  |O Not the NMC but the actual ups. I've tried the serial cable firmware update tool but to no avail.
I took the controller board out and discovered it's an STM32F103RC and they have very helpfully populated a SWD interface, so I dumped the ROM but the provided firmware file is not in a format I can figure out. (Both attached).

Any ideas what to do next?

DavidAlfa:
No idea if this is ok for that model:

Yes, almost at the end there's an hex file!

Sorry, the attachment didn't attach! It's on the first post now.
