This picture is from yesterday after crash , its not the state where it is now , ich have setting up all things but the model type i cant find in ext service menu

Are you able to recover root at this point? There might be a way to set right model using libFactory

I dont know did not tryed that , i am i little bit scared to do that

I understand. No other option than finding where "Basic model" is located in service menu then. It must be somewhere

I read in samygo wiki that i have to send factory and 3speed command for ext service mode , is that right ?

On my TV (F8000) I have these options (Local Set, SW Model...) are grayed. I unlocked these option with using the 3speed code on service menu (Change region (Local Set) on F series or change region).
Perhaps that on your TV these options is hidden and can these show with using the 3speed code. But these are just guesses.

Two options to access extended service menu:
-INFO+MENU+MUTE+POWER from TV OFF, then FACTORY+3SPEED
-INFO+FACTORY from TV ON

FACTORY alone exits service menu without having to reboot TV.

Does the factory code reset all ? I am scared to do that . Sectroya says we dont have to do that after root
