samygo-ffb fails to complete

Post by Dhardrian » Sun Apr 13, 2014 11:34 am

I have a Samsung PN58B860 Plasma TV which is currently running T-CHE7AUSC 1017.0 firmware. I have attempted to use samygo-ffb to downgrade to the T-CHE7AUSC 1013.0. I have already copied the samygo-ffb files to the TV successfuly. I have placed the T-CHE7AUSC 1013.0 firmware (from the official Samsung download site) on a USB stick, and run the samygo-ffb from the Content Library. The samygo-ffb software starts, however after detecting the firmware exists on the USB, it exits and the TV reboots. I have attached the _debug.log. It appears that the script is not correctly setting the names of the firmware files in the /T-CHE7AUSC/image folder on the USB. The contents of the official /T-CHE7AUSC/image folder are:

appdata.img.enc
exe.img.enc
info.txt
validinfo.txt
version_info.txt

The script is generating the following output in the _debug.log:

+cp -f /dtv/usb/sda1/T-CHE7AUSC/image/[T-CHE7AUSC]-Image /mtd_swu/
cp: /dtv/usb/sda1/T-CHE7AUSC/image/[T-CHE7AUSC]-Image: No such file or directory
+_FUNC_ERROR
+date +%H:%M:%S
+echo [00:08:38] Reboot on error or script end.
[00:08:38] Reboot on error or script end.

The entry from the ffb.sh file which is generating this error is:

#copy to DEPO u-boot.bin, Image and fnw.bin and checking md5 sums.
cp -f $USB/$image_dir/[$firmware_usb]-Image /mtd_swu/

I suspect there is something wrong with the "[$firmware_usb]-Image" portion of this string, which I believe is supposed be the filename of one of the firmware files to be to the TV. Can anyone help with this? Examining the script, it seems that it will be looking for three files to copy, while the listing I supplied above only appears to have two files containing images.

I have attached the samygo-ffb files transferred to the TV in an attached ZIP file also. The ffb.sh script being run can be found in the \samygo-ffb\1.FFB folder.

Do you have these three files next to appdata.img.enc, exe.img.enc etc on USB?
[T-CHE7AUSC]-Image
[T-CHE7AUSC]-fnw.bin
[T-CHE7AUSC]-u-boot.bin

Seems you`ve missed step 7. I don`t think something is wrong with the script, but with your files.

juuso,

You are correct. However, those three files are not included in the download from Samsung for T-CHE7AUSC. I have read on the forum that these files have to be added to the image folder, however it did not indicate where to locate them. Can you or anyone else point em to an appropriate archive?

i just want to say, you`re going to brick your TV. Why? Because you don`t read manuals.

Actually, I read the README supplied with samygo-ffb, which unfortunately did not mention anything about needing to copy these files to the firmware file structure on the USB, nor did it mention them at all in fact. I found the step you referred to in the forums after posting my question.

juuso,

My bad. I figured out where I went wrong. I printed out the wrong README. It helps to read the CORRECT manual... Thanks for you help.
