I ask for your help in trying to solve my problem
I had the unfortunate initiative of going for a ride in the Hidden Menu Samsung of my TV UHD series 6 UE50HU6900
I had a problem of an image freeze and a reboot of the TV during the playback of a movie by usb (fairly recent problem)
So by looking on the web, I tried to put the watchdog on OFF, then unintentionally I moved the option TYPE (I did not know what it was).
I tried a Factory reset but after the image of the TV is really weird with an unusual color tone then multiple attempts by moving the TYPE and FRONT COLOR
I tried load the last firmware's samsung on their offical website (Version : 1100.2 2016.08.19) but update by usb says there is not valid update file for my tv

I think that 's not a full firmware, this is just an update
So I'm looking for the right combination TYPE and FRONT COLOR for my model.
I removed the back panel for the labels in order to have as many elements as possible to try to solve my problem.
Between model name 6900,6900S etc ... and types ...I'm lost...
My current settings in options (which are not good):
Type: 50D6AUAVH / / Front Color: U-UHD-H9K
My options (I'm french)

Behind the TV

Inside, when the rear panel is removed

On IDE cable maybe

I hope this will help
thank you in advance
