Default F10 N55 JB4 - Firmware. Please help - 10-29-2020, 01:15 PM

I have an F10 N55 PWG with an old version of jb4 (with 4 wires, including can wires).
Tried to upload software today with the latest N55_F_PWG_INT_15_T1.hex
I'm using BMS cable and a Windows laptop for this

The update didn't go through and failed. Now Jb4 app says there's no software and car dies immediately after start.

what is the latest software version I can install? Can someone please share the HEX file here? The database only seems to have the latest 15 version, I couldn't find anything older.

Thank you!
