This is a tool to root LG TVs and automatically install Homebrew Channel. It uses DejaVuln, which works on webOS 3.5 and newer. This exploit will not work on TVs from 2016 or earlier.
Warning
LG has already started testing patched firmware. Do not update your firmware if you want to be able to root your TV.
While it has not yet been released, LG is testing patched firmware for several 2023 OTAIDs (W23O, W23H, and W23P: all 2023 OLEDs and more). It is likely that DejaVuln will be patched in any firmware with a webOS version of 8.4.x (codename number1-namtok).
I expect to see patched firmware for most webOS 4.5+ OTAIDs start rolling out relatively soon. However, webOS 3.5 will almost certainly never receive patched firmware, and 4.0 probably won't either.
Right now, unless you messed with the "NSU Mode" setting in the Instart menu (which is not recommended), you will not have patched firmware.
If you have a 2024 model, please contact us on the OpenLGTV Discord.
- Download the latest release (not the files named "Source code") from the Releases page.
- Extract the archive to the root directory of a USB drive. (It should be formatted with FAT32 or NTFS and only have one partition.)
- Plug the USB drive into your TV. (Make sure it's the only USB drive connected.)
- Open the USB drive in the Music app and browse to
lol$(sh$IFS$(find$IFS/tmp. - Try to play the MP3 file
(
usb$IFS-maxdepth${IFS}3$IFS-name${IFS}autoroot.sh)).mp3). You should expect to see an error message about being unable to play the MP3 whether or not the exploit works. - After the pop-up messages tell you rooting is complete, eject the USB drive.
If you have the LG Developer Mode app installed, you must remove it before rebooting. Do not install it while your TV is rooted.
You can influence the behavior of the script by creating certain files in the root directory of the USB drive:
autoroot.debug- Enables additional logging.autoroot.telnet- Makes a root shell available via telnet on port 23 when the script starts.
If the script fails, you must delete autoroot.once from the USB drive and/or
reboot the TV before it will run again.
A log file named autoroot.log should be created on the USB drive.
On webOS 8 (webOS 23), you may have to try multiple times; it seems that
restarting appinstalld does not reliably make it detect the existence of
devmode_enabled. May also apply to webOS 7.
Toasts from the script may be hidden by system messages (like the one about the MP3 file not being recognized).
If the toast and/or log says "Rooting complete" but you don't see Homebrew Channel, reboot the TV. Make sure Quick Start+ is disabled.
Make sure the archive is extracted such that autoroot.sh is in the root
directory of the USB drive.
You can find more information at webosbrew.org.

check the FAQ (#faq) to see if it is answered there! Attach your autoroot.log
