APC SMT3000I UPS after a failed firmware update via AP9630

[KrabKley]

There's been a disaster and I don't know what to do. I bought an AP9630 card and flashed it to the latest version v7.0.8 (at that time). Next, I decided to flash the APC SMT3000I via NMC. I did as instructed, turned off the ups, downloaded the latest update, selected the SMT18UPS_09-8.enc file and the process began, the light bulbs began to blink. The logs said that the firmware was uploaded to the UPS and then AP9630 said that the connection with the UPS was lost. The APC screen says Firmware Update in Progress… I waited 1 hour and had no choice but to turn it off. APC now does not react in any way and the display does not work. AP9630 is working, but does not see the UPS. It is preparing to turn off.

PS. i have cable AP 940-0625A

Do you have any ideas?
