Current versions of LGMOD can always be found here: http://openlgtv.org.ru/forum/viewforum.php?f=5


LGMOD is a modded rootfs for LG TVs models based on MStar Saturn 6 and 7 chipsets.

LGMOD was originally created by Vuk and was developed by him till v1.2. At that time, LGMOD supported only year 2009 TV LCD (LH/SL) models.

After Vuk dropped the project, Arno1 begun modding LGMOD from v1.3 and made it compatible with year 2010 LCD and PJ/PK PDP(plasma) series. He still active developer of LGMOD.

Beginning from version 1.5.7 Hawkeye made LGMOD sources available via SVN at http://openlgtv.org.ru/websvn/

At this time lprot joined the development. Patches have been released under many well-known versions of the firmware. Have been updated network card drivers to support more models.

On June 1st 2011, mmm4m5m ported LGMOD v1.6.10 to Saturn 7 platform and put it in SVN.

In October 2011 lgmodS7 version was ported to the platform S6. The new version of S6 has the following advantages:

  • Configuring the startup mode RELESE through webui
  • Built-in library libopenrelease
  • Emulation of the remote control in webui
  • Ability to place automated piece of software did not fit into the internal memory to external media.


  • Web browser user interface (embedded HTTP server on TV) for configuration and control
  • Ethernet network support via USB to ethernet adapters(dongles)
  • NFS client
  • CIFS/Samba/Windows network shares client
  • UPnP client
  • Easy installation/update from EPK file (Saturn 6 only) like official LG firmware
  • Scripts for customising startup and patching memory
  • Easy modules configuration through Web UI
  • Allows to backup configuration, firmware, virtually any file from your TV set to connected FAT16/32 USB drive
  • Ability to run linux shell commands from web ui
  • DHCP auto network configuration and network name resolving
  • NTP client
  • FTP server
  • Telnet server
  • Unicode support


Can be found in LGMOD folder of SVN at: http://openlgtv.org.ru/websvn/

Supported TV models

LGMOD is compatible with all MStar Saturn 6 and Saturn 7 based models ('At the moment EUROPEAN ONLY'):

'WARNING: TV models which have R letter at the end of the model marking are NOT supported. For example: 50PJ350R - is not supported. R models are Saturn 4 based.'

In fact if your TV is not listed, check the following list: http://openlgtv.org.ru/wiki/index.php/Opensource_packages_list

If you TV model has GP1 letters in the license column then your TV is supported no matter is it European or not.

List of all supported tv models. (All models are marked with the word "LGMOD" in the column "custom firmwares")

Supported USB to ethernet adapters

There is NO WiFi support at the moment. For Saturn 7 based models, read here: WIFI#Saturn 7

NB: In fact now supported all adapters from USB2NET drivers included in linux 2.6.26


MStar Saturn 6 and 7 chipsets are MIPS based.

Your LG TV firmware is divided into 3 parts: Bootloader, Linux Kernel, Filesystem (The later : Filesystem being subdivided itself into rootfs the master piece and other fs)

The application managing TV set is RELEASE (this is its name).

The bootloader U-boot is responsible of flash update firmware upgrade and starting linux.

The Linux kernel is the heart of the system and for Saturn 6 based on 2.6.26 version of linux.

The filesystem contains all context for RELEASE to execute.

LGMOD is in its current version is a mod to the Rootfs ONLY.

If you are interested in more customization better switch to (kernel + rootfs based on buildroot Saturn 6 only) openlgtv .


Currently rtokarev works on OPENRELEASE a wrapper with additional features that RELEASE is lack for: http://openlgtv.org.ru/forum/viewtopic.php?f=5&t=62

You can set my lgapp.epk (with openrelease) lgapp with openrelease. Pre-need to install the latest version lgmod.

Settings files / etc / openrelease / openrelease.cfg and openrelease_keymap.cfg.

Really useful additional features not much:

  • Enable / disable divx preview
  • Reassign the button on the remote control to switch off screen
  • Control your TV via virtual remote web interface

Everything you need for work openrelese have the current version lgmod.

How to install

For Saturn 7 - please, download, extract and read the steps in changelog.txt file.

Method 1, Flashing epk file from USB drive (Saturn 6 only)

LGMOD can be installed like any LG firmware update, with a simple USB stick :

  1. Create a directory LG_DTV at root of your USB stick
  2. Copy LGMOD epk file there
  3. Plug you USB stick into TV
  4. With remote control press "Menu", and higlight option submenu (do not go into)
  5. Press 7 times "FAV"
  6. Go for TV firmware upgrade

You're done !

(!) Do not install the same version-LGMOD on already installed LGMOD. If there has been a restart after the firmware upgrade - do not turn off the TV and do not try to flash a full version of the standard firmware - it will lead to the need to recover partitions with the aid of the console cable. Unless there was a reboot - you need to try again to flash the same or a smaller version.

Method 2, Flashing lgmod_xxxxx.sqfs via serial cable by Zmodem in U-Boot

If you can access U-Boot on Saturn 6 or Saturn 7, you can do the following procedure:


  • A serial cable RS232 (aka nullmodem cable)
  • A PC with some terminal emulator (for example you can use HyperTerminal or teraterm in Windows)
  • A USB pen drive FAT32 formatted (for firmware backup)

The procedure:

  1. Backup your firmware see here: How to backup TV firmware
  2. Flash rootfs (lgmod_xxxxx.sqfs)
  3. Switch off TV
  4. Plug serial cable beetween TV and PC
  5. Launch terminal program and set serial port parameters:

Port : COMx wher you connected cable (COM1 for me)
Baud rate : 115200
Data : 8 bit
Parity : none
Stop : 1 bit
Flow control : none

  1. Switch on your TV while press and keep holding "ESC" key on your keyboard until you get in terminal window the message (Saturn 6):
mstar #

On Saturn 7 you chould get:

saturn7 #

This is the command prompt of U-boot, the piece of the software responsible for flashing update if you followed the explainations above.

  1. Enter the command "loadz rootfs" which means to U-boot "update rootfs in flash via zmodem protocol"
  2. You'll get some strange things, don't touch any key anymore
  3. In terminal program send file by Zmodem and select lgmod_xxxxx.sqfs file (xxxxx - the version number)
  4. Transfer starts wait untill 100% finished
  5. When U-boot has finished receiving LGMOD it will write it to flash takes few seconds
  6. You will get again the "mstar #" or "saturn7 #" prompt once update finished, enter command "reboot" to restart the TV

LGMOD is installed !

How to configure

LGMOD include a web interface for easy customisation. Below are version 1.3.pre3 screenchots. Some further options/changes will appears along versions.

This web interface is password protected, default user is "admin" and default password is "lgadmin".

Web Interface Home Page

Web Interface Network Page

LGMOD Network.jpg

Example CIFS (Samba/Windows shared folder): First create "SMB" folder at the USB drive (or customize field "Custom"). Note that it is mandatory to enter a username (e.g. admin).
Device Path: //
Type: SMB
Local Mount Point: Custom...
Automount: yes
Username: NOT_EMPTY
Additional mount options: iocharset=utf8
Custom: /mnt/usb1/Drive1/SMB
Example NFS: First create "NFS" folder at the USB drive (or customize field "Custom")
Device Path:
Type: NFS
Local Mount Point: Custom...
Automount: yes
Additional mount options: nolock,rsize=8192,wsize=8192,udp,vers=2
Custom: /mnt/usb1/Drive1/NFS

Note: On the server enable NFS v2 only. The network throughput is about: 3,5Mbyte/s on Staurn 7 and about 2Mbyte/s on Saturn 6 using Asix compatible adapter.

Special configuration options without network access

  • If a file named "network" exist on root first partition of USB key it will be copied to TV and used as network configuration file, no more need to use vi on the TV to edit this file anymore, for those not familiar to linux/shell/vi.
  • Feature : possibility to reset configuration to default and save the current configuration on USB drive.

1- insert a USB drive with a file name "lgmod_reset_config" at root no extension, lower case.

2- Reboot your TV. Your old coniguration is saved on lgmod directory of usb drive, file lgmod_reset_config renamed lgmod_reset_config_used and TV configuration reset to default LGMOD (like fresh install).

  • Feature : auto_start.sh script now called at the end of lgmod, once RELEASE, USB and network working, you can add then anything you want to be done on your TV ! This script editable in webui tools page, some examples included (uncomment to make them active) :
    • Firmware backup
    • nvram backup
    • lgmod configuration backup
  • Added autostart script (auto_start.sh) called after lgmod (very end of boot process when drive/mounts/network available) and this script also copied from usb if exits.

Connect over serial port

  1. Start your TV set and wait until normal TV channel is playing.
  2. Start your computer and connect at 9600 , no parity, no flow control an 8 bits data and 1 stop bit (9600,8,N,1) with your favorit communication program (minicom is my case).
  3. Enter debug mode typing "debug" + enter key. Then again "d" + enter key and finally "sh" + enter key to get to the command console.

How to contribute

  1. Use it and report bugs
  2. Submit improvment suggestions
  3. Extract your firmware upload it somewhere and tell version, TV model and country and give link
  4. Propose your time to test new versions
  5. Make your own patch/development and submit them for merging

Customizing LGMOD

See Customizing LGMOD.


See LGMOD Patches for RELEASE.

Removing LGMOD


Install the latest stock firmware.


Flashing LG stock FW after LGMOD could brick your TV! Reason - not every LG FW will restore the lginit partition. (LGMOD installation does erase lginit and write new rootfs.)
You can flash first FW 3.1.8 - this will restore lginit partition of your TV.

Then install the latest stock firmware.
