Just for your amusement this is an example of the level of control I have on ALL LG TVs: the menus you see are custom made.

If LG C8 (which I don't know) has webOS, then yes.

officially: no. unofficially I can do it even remotely. Send me a PM.

Ah ok... saraà che sulla mia la 5.80.25 esisteva da tempo e la beta è 5.80.30 da tipo 3 mesi.

No In realtà hanno fatto un rollback ad una versione che funzionava

Don't update. No real advantages in 4.80.25.

Not YET.

ALL LG TVs can be downgraded. But I am the only one who knows how to do it without "hacks"

Yes. Send me a private message.

he probably meant IPK

Send me a PM. I can downgrade your firmware safely. Sorry I thought you had k3lp platform because I have 55UJ670V and I thought the 750 had the same platform.

Last official version is 05.80.10 and last beta version is 05.80.20. Where did you get 5.80.15?! If you send me a PM I can make you downgrade the firmware or you can install the beta 5.90.03 which is older than these but has higher number and it works. Check my post with all firmware versions for UJ TVs.

Updated original post with latest version.

Yes. I can remotely downgrade any Tv to any firmware. I doubt though that your problem is related to the new firmware because nothing has changed in that department. Drop me a PM if you still need the downgrade.

5.90.10 does not seem to exist and LG seems to have forgotten about 5.90.* versions. I suggest you to force update to 5.80.10
