Does that mean not even to future / higher original Samsung fw?
... and not even via USB?

that you can check if samsung release the next firmware version (guess update to original samsung firm will work, but who wanna get samsung original firmware? they just make restrictions no improvements....)

but who wanna get samsung original firmware?

Definitely not me, only asking in case I want to sell the TV... or if the set acts funny and I need to call a service tec.

they just make restrictions no improvements....)

Just wondering: why haven't you patched an earlier (<2000) fw then so there would be no restriction on fw downgrade?

for what? this version is ready to use. btw. if someone really like to revert to an older version he can decrypt an older usb firmware with samygo patcher and flash it manually over netcat shell and mmc.restore.

@arris69 any trick to get rid of error 800? I read about alex3333 trick, but I can't do it with my router

sounds so easy out of your mouth but I'm

So if Samsung wanna put sticks in our wheels, they can feel free to waste their time and money on that, instead of helping us out making their product better.

How about this: put all your guys efforts and talents into a different manufacturers TV sets.
I'd like to see SonyGo for example

I guess those guys would really appreciate getting such a damn good extension to boost their TV sales since it doesn't look too good for them
They might even support you...


Hope Samsung reads this

Yes !!! Found it!!! Magic string for hosts file is "192.168.0.2 az43064.vo.msecnd.net"
TV trying to download firmware from http://az43064.vo.msecnd.net/firmware/t ... appext.img (on my ES6100 with FW 1029). On 192.168.0.2 must be own web-server with /firmware/tv/154/SWU_T-MST10PDEUC_001030_I04_KS000RS000ES000DS000_121101/appext.img with right firmware. One little problem - i don't have rigth firmware image for downgrading.

the only problem is that you miss 2 other files what tells the tv information about the firmware images (like crc, signature, filesize, encryptionkey etc.)
simply present the tv an older file won't work then the checksumms are wrong
