I would guess from your firmware string that you have a "4th List Euro" version. The problem is though that the only way Lokifish could find to tell whether a given flashable firmware would work for sure, in the end, was to "flash it and see". If watch soft-bricked, then firmware was not compatible and needs to be flashed back to stock, if available, or a different replacement firmware that might work maybe.
You can imagine the support nightmare Lokifish would face.
