It does mean - use your TV software upgrade menu to install any firmware to TV, because it accepts from now pre-FEB firmwares.
You can skip this step if you do not plan activate alternative firmware from menu (you get post-FEB) this case :)

As alternative to step13 - alternateDel option in service menu.

1 - FFB is already copied to TV, I can select and run "SamygoHorse" in the Children contents (my TV haven't Game contents).
You have to run game called FFB, not samygo horse.
2 - In the same USB Key I've extracted pre-FEB firmware T-CHL7DEUC (version_info.txt: SWU_T-CHL7DEUC_002005_I02_ES000DS000_090930)
3 - Added in the T-CHL7DEUC/image, the files:
It's correct to LEFT [T-CHL7DEUC] in the file name ? Istruction tells: "do not rename!"
Yes, do not rename!
At this time I put the USB again on the TV, than run SamygoHorse ([CONTENT]->[CHILDREN]->[SamygoHorse]
Wrong! You have to run FFB. You should see FFB next to the SamygoHorse. That`s the reason you do not get it working - no log files, no messages on the screen.
P.S. in the USB key there are two folders: FFB and T-CHL7DEUC, could be this the issue ?
I haven't delete FFB folder after copy it to TV.
Wrong! I guess you haven`t got FFB copied to TV because you copied just subfolder.
First - extract archive FFB(v0.5).zip as is (folder /samygo-ffb)
Second - copy game to TV (yes, here you see only SamygoHorse - select - copy all)
Third - Add T-CHL7DEUC dir to USB and follow instructions.

I updated first post with images. Now i think everything is clear, right?

i`m sure, you are making everything well, but we have an experience - some USA models are more restricted as other. I do not know solution yet, but copy function does not work. Another our user has the same problem...
Read here and here.

All methods we know were tested and no success.

I have an Idea. Make please channel settings export to USB and give all files you get here (upload as archive to any web storage like rapidshare). And i need log from your ExLink.
