FFB says wrong Firmware for UN55B8500

[Avotos]

I followed the instructions to force the firmware back using FFB on my UN55B8500 but FFB says that the firmware T-CHE7AUSC 1013.0 is the wrong Firmware with a question asking If I want to Brick my TV ...

Based on the compatibility table, I was under the impression that "T-CHE7AUSC 1013.0" firmware was compatible with the Samsung UN55B8500

The current TV Firmware is: T-CHE9AUSC-1009.2

Help is Appreciated ...

This model not supported. Sorry.
Whats wrong with your current firmware?

Edit:
i could look at your firmware and perhaps it is possible to support it.
For this i have to inspect dumps first. Use this app, compress dumps and upload somewhere...
THanks.
