Thank's for the reply dar3k. I'll try it.
Can somebody send me md5 hashes for these files?

Mine are:

Code: Select all

MD5 (samyext4.img) = 26125ed8103a55e09c0aab82ed6a1129
MD5 (busybox) = d6cab1175626f10fc9ff03b6e84e9ea9

I've tried to do that with and without 2nd timeshift flash.

Check your pendrive, at first redownload samyext4.img because you have problem with that file:
"/dtv/usb/sda1/SamyGO/run1.sh: line 48: can't create /mnt/sam.log: Read-only file system"
Check also that file on your USB stick /SamyGO/busybox
In any case I think that there should be something else. I've re-downloaded all archives and checked md5 of files you mentioned — they are the same.

Try with another pendrive because

There script has copied file into /dtv
+ cp /dtv/usb/sda1/SamyGO/samygo_telnetd /dtv/

Here that file doesn't exsist:
/dtv/usb/sda1/SamyGO/run1.sh: line 22: /dtv/samygo_telnetd: not found
and this is something unnormal, you are sure your pendrive is FAT32?

Change pendrive and try once again from first step

"Quickly Power OFF Samsung" is not present. "Samsung Instant ON" is disabled.

Ok, will try another pendrive. But I suspect those "Terminated" messages. Looks like commands are not performed. When I've login with telnet after first reboot I was not able to run any command. Even "ls" where closed with this "Terminated" message.
I think that the main reason is:

Code: Select all

insmod: can't insert '/tmp/antysfd.ko': invalid module format

Just to be sure:

10. Reboot TV and wait 5 minutes. => Here I've switched tv OFF by my remote and then switched it ON.
11. Power OFF TV and UNPLUG USB. => Here I've switched tv OFF by my remote.

I'm not required to unplug TV's power cord for both cases. Is that correct?

Try with disconnect power cable and push power button on RC until red led will down. And than connect again (some models have software off)

You are constantly using NOT patched version of antysfd.ko. No idea why, but log clearly shows you do :)

As far as I understand this happens because SamyGO starts only first time after reboot. Then it fails with this:

Code: Select all

insmod: can't insert '/tmp/antysfd.ko': invalid module format
And does not even tries to start after applying patch.
What can cause this error?

I've tried to perform rooting process using already patched antysfd.ko
It runs and I'm even able to access TV by ssh. But it does not start after 2nd reboot. It only starts after first reboot when rooting is performed.

Also when using patched antysfd.ko, vermagic.txt is not created.

Here is sam.log: (other files are the same as in previous posts)
