[ROOT] Rooting E/F on latest firmwares

[devilhel]

Hello, my dear friends.
I wanted to ask for advice. Even in 2015, I set on the Root Samsung 40F6400 firmware T-MST12DEUC_1120. If my memory serves me was still needed for this Skype. In general, root was and I was satisfied. Then he had forgotten about it. And recently discovered that there is no Root (no access for ftp, telnet, and so on.) Read branch, concluded that the most likely updated smarthob. All updates I had been deactivated in the service menu. Root Installed in a new way. He appeared ftp, but became terribly slow down smarthub. You press the button "additional apps", and the set does not respond to any commands 2 minutes, then droops and everything works. If you open smarthub without flash card (which was installed samygo), then the TV hangs with a black screen. I wanted to update samyGoso but could not, do not have access to the section / mnt / opt / privateer / usr / bin is not right to overwrite, although all the files and folders in the properties is "full access". When I try to access tv through putty, he says he can not do (Network error: Connection refused). I Tried 1 and 2 method if problems occur:
1) If "occasional" root (not working as expected on every startup) it could be due to not fast enough USB detection, so you might edit / mtd_rwcommon / SamyGO / rcSGO file and add some sleep into it by editing its second line ( use advanced text editor such as Notepad ++, not Windows Notepad !!!) eg:
2) If no root at all, try to replace SamyGO-F-SM-MST-Fix / data / data.zip by this one on USB. This file already includes 'sleep 120' before autostart, so restart rooting procedure and wait at least 3-4 minutes before checking root.
Not working for me. In the first and second case - a black screen. Add you a log. (http://ctrlv.it/id/5245/3090721479 pass: 25653452)
I did a factory reset via the service menu. Everything happened exactly the same. I appeal to you, as it does not find the specific information that would help me.
I really hope for your help. Thank you. (sorry for my english)

Problems:
1. Cannot write/rewrite SamiGoso. Don't have permissions. (do not have access to the section /mnt/opt/privateer/usr/bin)
2. I need all times plug usb-flash on tv, otherwise smart hub don't answering (black screen)
3. Putty work's only by "telnet"

Trivia:
1. Pop-up messege "Virtual USB" (annoying)
2. How to turn off notification that Skype would soon will disable? (the menu has all turned off)
3. Tip's how to use virtual RC. (constantly shows how to use the r?)

Hi, I have F6740 model, with 2113 sw.
In service menu is not in menu OTN support, but I block firmware updates on router correctly.
On usb I have two folders SamyGo_data with samyext4.img and folder SamyGO-F-SM-MST-Fix, ofcourse with files from archive from first post.
In Smarthub-Donwloaded apps I found aplication SamyGO-F-SM-MST-Fix, but without icon, size is 0Byte and after start application I get this error:


Can you help me?

I have a F6270 with 2115 and i can root my tv without problems.

Try a "SmartHub" reset or a reset over the "Service Menu"

Everything worked like a charm for a year (or something), but since today I stuck with:

@danilabagroff & @atilla, Probably this is a solution:

[...] To prevent overflow samygo.log must also correct the 01_01_catch_crap.init (1st init-script). It is necessary to replace ">>" on ">" in the first row, which refers to the log.
Content of samyext4.img, by the way, is just growing at the expense of log-files. If the content is more than 134 megabytes, then there is a problem (cyclic reboot).
