We cannot make anything since your TV cannot enter to debug menu via 1198282 and resistance to break signals...
Ok. Well, I got the firmware I was waiting for. Would you like a copy of it for your own inspection? I'll try snooping around with the debugger/decompiler here, but with my inexperience I doubt I'll find anything.

You can give link here for your FW.

I also inspected FW and found that it using different AES key than ours.
Samsung changed it's AES key because of us? Probably.

We can't inspect file with unknown key.
Can you recover new AES key by installing firmware?

Needed to connect TV by serial console, than upgrade your firmware and needed to save/inspect output.
You needed to find AES key like in this post:

After successfully running the upgrade from my thumbdrive, I am now able to copy the SamyGO files to my TV memory again. :D Even though the version on my TV was 1009.2, it allowed me to write 1009.0 over it with no problem. I don't get the "New UPnP Server" message anymore when I run the app, but at least I'm able to troubleshoot that with greater ease and also telnet into my system. Thanks for your help. For those interested, the firmware copy that I obtained is here:
