I can confirm this is the case, my C8 updated to WebOS 05.50.10 yesterday and I had this message when I just tried to run the script.

Hello, I have rooted my tv with crashd Exploit Procedure.
I activated the ssh server in homebrew channel and restarted my tv but when I try to connect with putty the connection is refused without being asked for the credentials. What can I do ? Thanks

Same problem with my B9 Firmware 05.30.10, The process seems to complete without errors, but the homebrew store did not install.
Same here for my SM9450 running 5.20.35/4.9.5-14, seems to root and download package fine no errors, but no HB channel.
I confirm, Lg 65C9 with 5.20.35, root fine but Homebrew Channel don't show...
maybe it has been fixed?
we hope for a solution

Would this work with an LG TV from 2016, model 70uh700V-za, from 2016? I'm running WebOS TV Version 3.4.0-5711 (dreadlocks-digya). Firmware version 05.60.35
Edit: Confirmed to be working on LG 70uh700V running 3.4.0-5711, firmware 05.60.35!

Same here with LG OLED65B7D-Z. After upgrading from 06.10.01 to 6.10.30, rootmy.tv is processing but unfortunately neither homebrew channel nor evelavated root Access.
aah... 4.x.x have startup script problem. but developers working on it. Add a repo to homebrew "https://repo.webosapp.club" and install run.telnet application. try connect telnet with putty port 23. and run this commands for ssh. its temporary solution for ssh. Sorry for my english.
Bash:
mkdir -p /var/lib/webosbrew/sshd
/media/developer/apps/usr/palm/services/org.webosbrew.hbchannel.service/bin/dropbear -R
sed -r 's/root:.?:/root:xGVw8H4GqkKg6:/' /etc/shadow > /tmp/shadow
chmod 400 /tmp/shadow
mount --bind /tmp/shadow /etc/shadow
sed 's/root:\*:/root:x:/' /etc/passwd > /tmp/passwd
chmod 444 /tmp/passwd
mount --bind /tmp/passwd /etc/passwd
For everyone who does not work with rootmy.tv, use the new instructions:

RootMyTV is a user-friendly exploit for rooting/jailbreaking LG webOS smart TVs.
Website: RootMy.TV
GitHub: https://github.com/RootMyTV/RootMyTV.github.io
For further details, and a full writeup, please check out the GitHub repo.
TL;DR; If you want root on any* current WebOS LG TV, do not install updates for the time being, and wait patiently. If you're a developer or researcher, read the latest update below.
*The exploit requires "ThinQ" support, which seems to only be available on TVs running WebOS 4.0+. I will update this when we know more about which versions support it.
RootMy.TV is an 0-click (kinda) web-to-root exploit for WebOS.

GitHub (placeholder): github.com/DavidBuchanan314/RootMyTV
After this bug in Download Manager was published (which, on its own, allows rooting the WebOS emulator), I was motivated to find new bugs which can be combined with it, to get root on actual TVs.
Given the relatively severe impact of this exploit chain, its publication will have to wait at least until LG makes official patches available for the Download Manager bug. After that, I will be publishing the exploit, along with a full writeup.
During my research, I received invaluable advice and information from members of the openlgtv Discord server - I definitely couldn't have done this without them. Please join us, if you would like to assist with testing the exploit etc. in the hopefully-near future: https://discord.gg/9sqAgHVRhP
Update 2021/02/15:
LG claims to have fixed the Download Manager bug, but they haven't really. To motivate LG to actually patch the bug, I will be disclosing my exploit chain to them under a 30-day public disclosure deadline - after which, I will be publishing the exploit here. Assuming I send my disclosure to LG email tonight, that sets the RootMyTV "release date" at 2021/03/19.
Update 2021/03/18:
The release date is now 2021/03/21 - I have a few things I need to finish up...
Update 2021/03/23:
Sorry for the delays...
I am attaching a bare-bones vulnerability report and PoC for the exploit, which is enough to get you root. This "pre-release" is intended for developers and researchers. If you're not a developer or researcher, please be wait for the "full" release, which will hopefully arrive in the coming weeks. The final release will be more user friendly, and include a "Homebrew Channel". If you would like to contribute to development of the Homebrew ecosystem, please visit us on Discord.
Some notes/disclaimers about the exploit: (READ FIRST!!!)
- This will void your warranty, don't blame me if anything goes wrong etc. etc.
- Amazon's "google play store" link, described in the writeup, is currently broken. As a workaround, you can search for "google search" on Amazon, Click the top result, Click "developer info", then click the link to Google's privacy policy. From there, you can click the menu icon in the top-right and continue with the rest of the instructions.
- Something I forgot to mention in the report - you must update the value of the "HOST_PREFIX" variable in index.html, to point to your local webserver.
- If you were previously using Developer Mode, then overwriting `start-devmode.sh` will have broken devmode features like `ares-install`, and the jailed sshd. You can fix this by putting the old `start-devmode.sh` back again, with some edits.
- For some TVs that don't have the ThinQ login page, you can access an equivalent page via "Account Management" in the settings. This doesn't work on my TV (the amazon link opens in the web browser), but apparently it works on some models/versions.
- The current version of the exploit will give you a root telnet server, accessible on the default port (23), without authentication.7
You're in luck. Just this week a user at AVSForum reported that you could enable Motion Pro on the C9/E9 with a simple command on the tv. The only disadvantage was that you need to execute this command with root privileges. Now that is where this thread comes in.
I've managed to get root access to my C9 and have executed the command and it works! Motion Pro low, medium and high is available and works at 120Hz.
This is the command that you need to execute:
Code:luna-send -n 1 -f "luna://com.webos.service.config/setConfigs" '{ "configs": { "tv.model.motionProMode": "OLED Motion Pro" } }'4
If you really want root, you can try this method in the video, it's the most resent way.
3If you are having trouble connecting to certain websites or using Plex or Emby on your TV, it may be because the services are using digital certificates signed by the new LetsEncrypt Certificate Authority cert, and LG have not updated the TV’s certificate trust store to include this new cert and remove the old expired one.
If your TV is rooted, then you can use this shell script to fix thIs: https://github.com/tf318/lg3With the just released firmware update for the 2021 OLED TV models, the last model without a fix has also received an update that fixes the corresponding security vulnerability.
Thus, the method used by RootMy.TV to gain root privileges should no longer work on any of LG's OLED TVs (2019-2022) if they have the most recent firmware version. Note that installing apps via RootMy.TV may still work.
