LG TV running 04.26.35

[Revoola]

The tv should as i understand be rootable, the tv shows the following messages:-

start-devmode.sh:Downloading from undefined...
start-devmode.sh:Luna call failed:{"retunrValue":false,"errorCode":-1,"errorText":"Service does not exist:
com.webos.service.downloadmanager."}
Original start-devmode.sh overwrtie failed, attempting v2 exploit...
extra_conf.sh:Downloading from undefined
extra_conf.sh:Luna call failed {"returnValue":false,"errorCode":-1,"errorText":Service does not exist:
com.webos.service.downloadmanager."}

Can anyone please:-
a. tell me what they mean
b. what have i done wrong?
c. how do i fix it?

@Revoola

Your TV is running webOS 2.

Is there no exploit for it or a lack of the compatible library supported for the exploit ? I got the same firmware and it was probably the last one ever.

so no other ways to root?

I'm sorry, even though I do have experience with Electronics and stuff but,
I do not feel comfortable opening up my TV.
Is there any way I can root it without opening it up?
there is a port labeled "Service Only" at the back of it.
it looks like a AUX port but I think it could be some sort of root access perhaps?
