mtd_rwcommon reset?

[Ceikor]

I have a UE46F6270 FW 2110.

How i can reset the mtd_rwcommon partition?
I have write a script to wait for files from USB device with a while loop and i forgot a "/" and now i hav a loop in the background without exit -.-
and i can not use any widgets. if i go to the app site on the tv, the TV hangs when loading the apps. i have no ftp or telnet access. Factory reset was not helpful.

PLEASE help me

Where do you launch your faulty script for it to prevent root?? Surely not at a recommended place
You should check if you can get access to netcat on port 4023.
Anyway, you're using USB root, so I don't see where something could be "irreversible"...

My problem is, i have change the rcSGO to

Code: Select all

while [ ! -e "dtv/usb/sd*" ]        <----- here is the probleme, i forgot the "/" on the begin to check path,
do 
	sleep 2
done

........

so the while can not find a "dtv/usb/sd*"
this is my big fail, so and this script block now the smart hub, i can not start any other widgets (usb or intern)


Edit:

Code: Select all

Connection to 192.168.178.38 4023 port [tcp/*] succeeded!

You can take new version of samygo with unchanged rcsgo on usb and get root back. No?

[zoelechat]

Netcat works the same way as Telnet, install for example nmap exe package: https://nmap.org/download.html#windows
then open commandline and enter command:

Code: Select all

ncat IP_OF_TV 4023

But if you just replace rcSGO on you rooting USB by original one, problem will be simply gone

No, smart hub don't show the widget on the usb stick and i can not install over dev account. The login is greyed out.

EDIT:
The problem is, this is a rcSGO from "/mtd_rwcommon/SamyGO/" and this is the first file to start.

[zoelechat]

Then kill your process through netcat
And replace rcSGO by original one (you put on USB)

[Ceikor]

Can you tell my how? Sry for this noob question.

EDIT:
Ok i will test to usb

EDIT2:
The result is the same, i have copy the rcSGO to the USB root but samy not use this file. How i can kill a process over netcat?

[zoelechat]

Put the right rcSGO to the root of your rooting USB (let's say /dtv/usb/sda1)
Connect to netcat as told above, no prompt is expected but you can enter commands.

Find the faulty PID (the number at the beginning of a line containing rcSGO !)

Code: Select all

ps -A

(or "/bin/ps" if TV tells invalid option -A)

Kill it

Code: Select all

kill FOUND_PID_NUMBER

Then overwrite script by original one from USB

Code: Select all

cp -f /dtv/usb/sda1/rcSGO /mtd_rwcommon/SamyGO

Done

Next problem, if i use "nc -vt 192.168.178.38 4023" over Linux Mint i get

Code: Select all

Connection to 192.168.178.38 4023 port [tcp/*] succeeded!

but i can not enter any command.

If i use "ncat 192.168.178.38 4023" over Windows, ncat say:

Code: Select all

NCAT: An existing connection was forcibly closed by the remote host...

my firewall is completely off
