E-Series Firmware Downgrade (SamyGO Proof of Concept)

[arris69]

Precheck:
make sure in tv's settings menu OTN is enabled (screenshots anywhere????)
if you once played around in service menu, try to remember you changed some settings to develop(er|ing), if yes set it back to operating, if you never changed it in service menu there is no reason to change now anything!!!!!.

1. set dns (depends on you network setup on tv or/and on your router) to:
   
2. switch tv off and on again
3. check from tv's menu for firmware update via internet
4. install firmware if it detects one (firmware for e-series TV is not patched, it's original samsung firm with just changed versions number to xx90)
   
   • if you get an error at ~90% of install process turn tv off for ~3min and try again
5. if no firmware are shown -> report it (not to samsung but here in SUPPORT forum )
6. set your dns back to normal operational (if you don't do this your device will be banned after 2 days on server due senseless filling up of logfiles)
7. turn tv off and on again
8. and don't forget to disable further firmware updates!!! (samsung won't make any technical improvements in new firmwares)

if you like you can say "thank you" here too

SamyGO Patched Firmwares!!! on Server (Extensionspack included with autostart, webserver on port 1080 and netcat shell on port 1023, Features):

• T-ECPDEUC 2003 (success: verified) one way game, no downgrade or upgrade to any other firmware version possible
  
• T-MST10PDEUC 1030 (success: verified) one way game, no downgrade or upgrade to any other firmware version possible.
  maybe also virtual usb broken (let us know if you have "fixet" it)

Prepared Samsung Firmware on Server (original, just for downgrade):

• T-ECPAKUC (success: verified)

Prepared but closed for public access:

None

Maybe supported in future, but just if multiple users make requests:

None

I have an UE46ES6300 with T-MST10PDEUC as firmware, i changed the DNS as indicated but no update was found.

Any progress ?

[monoschwarz]

Maybe supported in future, but just if multiple users make requests:

T-ECPAKUC
T-ECPDEUC
T-MST10PDEUC

i have a

Model UE46ES6340-----Type 46A1AF6E
Firmware: T-mst10pdeuc-1011.1-----T-mst10pdeus-1001

and i can login to develop

I would like to use the last version where I can SamyGO and it would be good if we could downgrade this unit standard is there that is sought after 4 hours in standby for updates. that means who do not pay attention very quickly an update on it

What is "OTN" ???

Thx

in the service menu
(TV off, quick info, menu, mute, power;)

control; ---- Sub_menu; --- option_SWU

there are a few settings

ONT ServerType = Operation / Development
OTN test server = Off / O-Zone / B-Zone/..../E-zone
SWU reset
SWU Fail Test= on / off
SWU Duration = ON /Off
OTN support = ON / OFF
SWU_Diag_code

what settings you need to run to downgrade
(Default is bold)

Thanks for your work!
A prepared firmware for T-MST10PDEUC would be great.
