You Can Now Jailbreak A PS4 With An LG TV (hackaday.com)

On the off-chance that anyone here tried the jailbreak method using your TV:

I was able to root my TV using rootmy.tv really easily and am now trying to connect my PC to the TV using SSH or telnet in order to run a couple commands and send the needed files to trigger the jailbreak. However, I can't for the life of me connect using SSH or telnet - I get a "connection timeout" error everytime, making it impossible to log into root. The IP address and the port I enter are both correct (22 or 23 for the port depending on if SSH or telnet is chosen).

I tried a couple methods to install OpenSSH since in my research it looked like this might be an issue which also didn't work, tried disabling my firewall, adding the program to the exception list in my firewall etc. - nothing seems to work.

Any ideas?

Maybe your ip is coursed you could try using a port forward on your router and then install cloudflared if possible. Might be worth a try. Worked for me in a different situation.

I'll look into it and let you know how it goes. Thank you :)

Why root a tv?

[–] [email protected] 5 points 5 months ago

You have access to specific homebrew apps that add features and allow for shenanigans like running an exploit off the TV itself instead of needing a PC like in this case

Unfortunately LGTV's can't be jailbroken unless you were lucky enough to jailbreak it back before they patched it.

I got mine last year and had no idea the security on it was so tight. I'm just hoping smarter minds than mine can figure out new exploits for the LGTV now that there's demand with the ability to jailbreak PS4s

If Nintendo and iPhone can be jailbreak, then everything else can be too.

[–] [email protected] 5 points 5 months ago

The people with appropriate skills must have the tv (it's not cheap) and actually interested in jailbreaking them. So far noone has done so.

[–] [email protected] 1 points 5 months ago

I'm holding out hope!

I'm going to disable all automatic updates in the event that it happens!

[–] [email protected] 20 points 5 months ago

Have recently jailbroken my PS4 and am now contemplating rooting my TV as well. We bought it a couple of years ago and have never connected it to the internet, so the model plus WebOS version should be compatible with the root.

[–] [email protected] 17 points 5 months ago (2 children)

Since you need to connect the PS4 via ethernet, wouldn't this also work via a normal computer?

[–] [email protected] 11 points 5 months ago* (last edited 5 months ago)

Yes, it does. The standard method is to use a PC with Linux or Windows and install a program that triggers the jailbreak on your PS4 whilst connected to it via ethernet cable. Using a TV makes it a little more hassle-free depending on your setup since you're turning on your TV anyways and don't need to use the PC at all.

[–] [email protected] 6 points 5 months ago

Yes, but that's boring, they even mentioned it in the article right before they talk about the Ethernet port, here's the link if you want to do it yourself https://github.com/TheOfficialFloW/PPPwn

Does this open the door to an exploit over HDMI?

[–] [email protected] 48 points 5 months ago (3 children)

Not to be a Debby Downer, but you'd either need a LG TV which is already rooted, or one you can root (per the repo's README, "RootMyTV is unlikely to work on firmware released since mid-2022" and given firmware downgrades are impossible...).
AFAIK firmware updates are opt-out by default, so as long as you connect your LG TV to internet, you're likely to have received one, but I could be wrong.

[–] [email protected] 7 points 5 months ago

You should try it anyway, I have a rooted lg oled running the latest firmware. Updated a couple of weeks ago.

[–] [email protected] 4 points 5 months ago (1 children)

Yeah I was excited about this but then realized I take every update LG puts out there, lol

[–] [email protected] 20 points 5 months ago (2 children)

my LG TV was up to date but I still managed to root it just recently, via this method: https://github.com/throwaway96/dejavuln-autoroot

it's well worth it - rebinding the remote alone is sweet AF, plus the ad-free and sponsor-blocking YouTube is great

[–] [email protected] 3 points 5 months ago* (last edited 5 months ago)

Just rooted it... Worked perfectly, ad free YouTube here I come!

I wonder if I should use Kodi on webos or stick to it being on my Chromecast, as it has more space and power I think

[–] [email protected] 4 points 5 months ago

Holy crap really? I'll check it out asap thanks!

[–] [email protected] 29 points 5 months ago (1 children)

On the other hand, a person who would root a game console or TV is also likely to be the sort of person who would opt out of smart TV updates.

[–] [email protected] 28 points 5 months ago (1 children)

Maybe? You would need to know rooting a TV is even a possibility in the first place, I had no idea that was the case and I've had my LG TV for over 4 years.
I'm just pointing out some specifics of the prerequisites, which the article did a pretty bad job of highlighting imo, and how this is not the miraculous solution it's somewhat touted to be.

[–] [email protected] 11 points 5 months ago* (last edited 5 months ago)

I’m just pointing out some specifics of the prerequisites,

Yes, that's fair.

which the article did a pretty bad job of highlighting imo, and how this is not the miraculous solution it’s somewhat touted to be.

It would also be fair to acknowledge that hackaday is not touting miracles, but simply knows their audience. One would have to be very new to hardware hacks like this to be unaware that preconditions almost always exist. Older firmware is one of the most common preconditions.

LG TV owners rejoice because their used TV value has suddenly spiked

[–] [email protected] 11 points 5 months ago

C8 represent!

I fucking love headlines like this 😂
