E-Series Firmware Downgrade (SamyGO Proof of Concept)

[hondavtec]

Just tried again to connect to 46.4.199.222 and currently I always get 601 time out error.
Internet works fine otherwise... arris69 are you currently working on this or is it just down

Currently downloading 002090 on PS51E8000 with original 2002 fw.
Am I just lucky that it's working now or have you changed something... perhaps routing on your side?

[hondavtec]

Unfortunately it's been too early for me to be happy...
Update always stops at 96% with Error 709 - invalid parameter, no new update on server:

no, there is nothing changed here on server, and never needs to be changed , just wonder that tv starts with firmware 2002 the download...

samsung implemented some extra checks in 2xxx firmwares (in 2002 its maybe in beta state), so for now the downgrade won't work for e-series (with firmware >1999).

What about for the T-MST10PDEUC 1027-1030?
Can manual downgrade be performed?

(I was just forced to upgrade to 1029 after loosing channel memory...)

No chance for MST10PDEUC 1030 so far...

However, I'm still trying to reproduce how I could get ECPDEUC 2002 to download the SamyGo patched fw up to 96%

[hondavtec]

• T-ECPDEUC 2003 (success: verified) one way game, no downgrade or upgrade to any other firmware version possible

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

for MST10 same situation (with firmware 1030, dunno about version before).
