This guide should help you downgrade the software on your LG TV so you can get root if you've updated to 3.30.10 like I did.

I've tried to include as much information as I can and there are 3 methods to choose from on the GitHub

This has been tested and confirmed to downgrade on an LG 43 Inch TV 2021 Model - LG-43UP75006LF https://www.lg.com/uk/tvs/lg-43up75006lf from Software Version 3.30.10 to 3.21.30 but should work on other LG TV models too with the relevant firmware for that TV.

Hope this helps and let me know if you've tried it

Dude this is awesome! Thanks for putting this together. Unfortunately, I cannot find a suitable previous firmware for my model(70UN6950ZUA). I got the reference list and tried all 73 models but I couldn't find any on the Korean website. I'm not giving up though. I will now scour the internet for firmware.

Well I found a the right 3.21.75 firmware for my tv using the way back machine! Unfortunately, I tried all three methods of downgrading and none of them worked… I can get to the usb software update screen but when I click update it just tells me it’s unable to update. My tv is on webOS 5.3.2-2208 software version 4.35.30 and I currently have a pending update to 4.40.09.

Thank you
With your tutorial i could downgrade my tv (wich is the same as yours, that would have helped me alot if you told wich korean model match with it) with method 3 (i like ssh on things :D )

You could had there is a Telegram group where there are all the lastest exploitable firmware : https://t.me/lgwebosusb

So nice job again ;)

I have a 50" UN 70006LA and downloaded the latest firmware image from the telegram channel. All three methods fail with my current installed SW (4.40.09). Is there someone with the same issue and managed to downgrade the firmware?

Unfortunately, I can't find old firmware for my OLED77A19LA anywhere. Anyone knows where else to look?

This morning my unrooted OLED55G26LA tv updated to sw 03.21.45 and WebOs 7.2.0-47 (mullet marine)

Is there any way to root this tv?

I couldn't find my TV model nor any of the related models on the Korean LG website. If I try to use a different firmware is there a risk to brick my TV?

Hi there! Thanks for sharing this guide on downgrading LG TV software to get root access. It's great to see that you've included multiple methods to choose from on your GitHub page. This will be helpful to many people who have updated to version 3.30.10 and are looking to gain root access. If you need to test it professionally, I suggest using zaptest.com. Good luck, and I hope this helps!
