Yes! I upgraded my UN32D5500 to the newest firmware and I want to downgrade it in order to install SamyGo extensions.
Is it possible?

if you tell me from where i can download an old version of the firmware then maybe.

PS51D550 (T-MST4DEUC) downgrade successful, but no further upgrade possible...

yes, then you downgraded from non restricted firmware (released by samsung before december 2011).
those firmwares don't correct the "faked" versions number.

ps: you forgot to write here your firmware version (1024)

I had 1026 and upgraded to 1027(May 2012) before I tried the downgrade. I thought the version number would change, but it didn't. So I used the 0000 firmware.

An report from the Hifi-Forum said that D5 users can regain upgrade-ability, after DNS-downgrade method, through a factory reset. After that the version string is corrected.

No available firmware here, when trying to downgrade 46d6530 T-GASDEUC 1018... My OTN settings are:
OTN server type - operating
OTN test server - OFF (i've changed this option to zone D without sucess)
OTN support - ON
OTN durnation - ON
OTN fail test - ON

Any help?
I installed long ago the samygo widget as explained here: http://wiki.samygo.tv/index.php5/Rootin ... er_account
DNS has not been changed since widget installation....maybe i'm banned?

You haven`t used SamyGO DNS for widget, you used develop server IP. I think you should follow the how to step by step...

Help!
Hi!
I did successfully upgrade (original version 1018).
Now the Current Version: 00190
If I run Smart -> SamyGO application, do it successfully, then exit and restart after a few seconds on TV.
The firmware restoration does not work.

Complete Noob here, but after a bit of head-scratching I have just downgraded a UE46D8000 from firmware T-GAP8DEUC version 1021.3 to version 1015.0. It did tell me it was installing version 001090 while it was doing it, which had me worried for a while.

Well done - like others I now have to go and work out what to do next.

New here. Congratulations for the great job.
I succeeded downgrading my UE 46D8000YS from firmware 1023.1 to 1015. Now it shows as T- GAP8DEUC-1015.0, BT-G in the tv info menu page.
But?now when I try to upgrade to 1018.1, the last official compatible with SamyGo, either by usb or online, it says no file available for upgrade. Tried with intermediate firmwares between 1023.1 and1018.1 and with the same result.
Is there any solution? Thanks
