Help with bricked APC UPS SMT1500
PeeJay:
Oh, so it's likely the 89C51RC/93LC66 with bad firmware then?
It's strange that I get no response trying to communicate via the RTU port. I made a cable according to https://pinoutguide.com/UPS/apc_0625_cable_pinout.shtml which matches what you wrote, I checked for continuity to the pcb pins as I was using a RJ45 connector. Perhaps I should have tried swapping tx/rx?
I've since seen a few other posts from people who had timeout errors like me when trying to flash via the web interface on the NMC, but I'm not sure if any of them managed to resolve it.

Hi,
Just bricked my smt1000i also during a firmware update.
Luckily i got it for cheap so it isnt a huge loss but ill see what controlboard mine has.
edit: Tried the exact same firmware version you did....
Edit2: Mine has a 640-3081A_REV06 board. dont know if thats the main one.

I also bricked my SMT1500 trying to update the UPS firmware.
Some of the info in this thread is way over my head but still curios to know if you were successful in recovering the UPS?
My control board appears to be 640-3081_REV03.
My unit is a 2011 manufacture date so about time to retire it anyway but it would be nice to recover it.
