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

[AlbaJoeReturns]

BTW going down to 1015 you lose the ability to watch netflix and youtube 3D

Tried upgrading to F:\T-GAP8DEUC on my PS51D8000 ..... but TV doesnt find it off my USB stick ?

@AlbaJoeReturns: You first need to execute the T-GAP8DEUC.exe to extract the update-files to an usb-stick.After that you can do the upgrade via usb...

I did m8 yet it still doesnt recognise the file. Its the same process and USB stick that I have used on my other TV C7000 series so it really should work.

I got the file off the WIKI page so assume that is ok too ?

Did you manage the upgrade just like written in the instruction?

Have any. Of you guys downgraded your firmware hen upgraded and downgraded again e.g 2003 to 1015 to 1018 to 1015.

I have noticed reduced brightness on getting back to 1015 from when I did it first time round.

Is it Possible?
