Hi is possible to modify the file usb_cmd created in mtd_rwarea from link0 after the hack?
can i simply re-edit it with notepad++ and reboot tv to apply changes or i lost my hack?I have done hack and i've full access to my tv run.sh is executed from usb.
i want to modify my usb_cmd according to here viewtopic.php?f=13&t=1076#p9426

Do not ever edit scripts with notepad.

I`m not vell with that hack, but i think everything should work after modiffication. If not, you always can re-hack

i try but the results was that tv can't recognize the usb connected to tv so i've to rehack.
i don't understand if the error is due to the wrong usb_cmd maybe i've to ask @mamaich but it's no longer on samygo forum.
juuso do you know how to create a init script for telnet? i'm thinking to start the telnet daemon from busybox present in SamyGO/bin directory but i've no idea in how to do it.

so as far as i understand you want to have the modified version of usb_cmd to have telnet enabled?
do you plan on using SamyGO-Extensions? If yes you get a ssh-daemon with it which is more comfortable than telnet.
as you still want to look for a run.sh file on your usb-drive, why don't you put the telnet part of mamaich's script into your run.sh on usb-drive this way the risk of breaking something is way smaller

i want telnet because is more simple to use for me instead of ssh, telnet don't need login every time i launch it.
i stilll have the run.sh that launch telnet and ftp after tv poweron.
my goal was to create one step usb hack.

take telnet script from any other series and adapt for your needs. Example:

Code: Select all

#!/mnt/bin/busybox sh
#
# ? Copyright 1996-2013, SamyGO
#
#
. /dtv/SGO.env

stop_bootloop()
{
# emergency skript exit to prevent boot loop
      for USB in ${1:- \
         /dtv/usb/sd* } ; do
         echo "checking $USB"
         sleep 1
         if [ -e $USB/STOP_TELNET ]; then
            "STOP_TELNET found. Script exit..."
            exit 1
         fi
      done
}

case $1 in 
	start)
	stop_bootloop # in testing phase. Just for protection.

	# telnet
	$SYSROOT/bin/busybox2 telnetd -p 23 -l $SYSROOT/bin/ash &
	sync

	;;
	stop)
	;;
	status)
	;;
	*)
	echo "Usage: $0 {start|stop|status}" 1>&2
	exit 0
	;;
esac

Have you changed TV that you are trying to hack?
Because on the first file you posted, you have channel_list_LE32C530_1001.scm and on the second you have channel_list_LE32C550_1001.scm (530 vs 550).

Assuming that the first file has a valid dump of your channel list, I have built you the contents for both sda and sda1:

• sda: http://bit.ly/dGAUmq
• sda1: http://bit.ly/dTEslI

Try to do a Factory Reset and follow the rules from the first post:

1. Attach USB to TV, restore channels from USB: "restore from USB"
2. Activate Hotel Mode by pressing {INFO} {MENU} {MUTE} {POWER} while in standby
3. Insert USB you made before, do settings restore: "restore from USB" from the "Hotel Menu"
4. Re-insert USB
5. You should see file run.ok on USB

would anyone have the files listed here? i have a B2430HD (very similar to B2230HD) and it seems hackable, however it gives me a "No file available" error when trying the hotel mode hack on my own.
i dont know much about hex editing, and i tried basically everything in that Clone.dat file (from xxd to manually modifying the original file, none worked)

im not the first one to have this issue, and the original person who was trying to hack their B2230HD also had troubles with this error, but they said they used these files to make it work. problem is: these files are now completely lost (404, cannot find any archives of them)

kinda offtopic but: since when did dropbox files just randomly expire
