Your problem is you missed
step 7a from How to.
Files [T-xxxxxxx]-u-boot.bin, [T-xxxxxxx]-fnw.bin, [T-xxxxxxx]-Image (where xxxxxxxx is firmware version) needed to be placed in the same directory as exe.img.enc, appdata.img.enc and other firmware files (inside /image/ directory)
Check log:
+cp -f /dtv/usb/sda1/T-CHL7DEUC/image/[T-CHL7DEUC]-Image /mtd_swu/
cp: /dtv/usb/sda1/T-CHL7DEUC/image/[T-CHL7DEUC]-Image: No such file or directory
[00:03:13] Reboot on error or script end.
<...>Content of /dtv/usb/sda1\/T-CHL7DEUC\/image:

I see, but in downloaded archive (LExxB65x, LExxB75x, PSxxB65x) is "[T-CHL7DEUC]-Image" without " *.bin " extention. Do i need add it manualy or it is just some mistake in example of file structure? (Structure you have to get on USB(example with T-CHL7DEUC, if your TV has other firmware, you have to get your firmware here): .... ----------------[T-CHL7DEUC]-Image.bin)

Thank you! Firmaware is back! Image.bin - is just mistake in example, you can remove ".bin" from text there.

Thanks, excellent tutorial!!
I have successfully downgraded from T-CHU7DEUC-3001.1 to T-CHU7DEUC-3000.G
Model TV: UE46B7020
Now I can't wait to install SamyGO apps.
I have followed all steps 1-12, but I don't understand step 13. Is it necessary to delete post-FEB firmware from TV? How it can be done?

Skip 13 step. But be sure you wont accidentaly activate post-feb firmware again.

Hi, I have a question. My firmware is probably 2004.1 (please see
https://goo.gl/photos/9uKc7kk4DCMr6NAg7). Do I have to do all the steps? Or can I just start from step 7 (the one before 8, it is actually without a number
. Thanks.

You do not need FFB at all. What is your goal?
