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.
thanx for report, looks like here again: samsung has no standards...

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

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.

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.

(My TV 40D6570)

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.
