TV D-Series Firmware Downgrade (SamyGO Proof of Concept)

[optico]

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

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)

Factory reset done.
Menu -> Support -> Software Version 001013
SamyGo app is running -> done. Automatically exit from smart, and a few seconds after the restart the TV.
Update 001016, SamyGo app running, and the same. TV restart.


Problem solved!
001013 to install and then service menu -> factory reset
001016 to install (due to youtube 3D) after service menu -> factory reset
SamyGO app installed and working properly!

Successfull downgrade from GAPDEUC 1023.1 to GAPDEUC 1015.0.

But now cannot update to 1018, just says no update available yet, I have factory reset twice and still the same?
Any ideas?:?:
