Work in progress!

SamyGO DNS service

Is used only for Firmware downgrade and Patched firmware installation on C/D/E series for supported models only. You further acknowledge and agree that we are not responsible or liable, directly nor indirectly, for any damage or loss caused or alleged to be caused by or in connection with use of or reliance on any such Content, site or resource.

Precheck:
If you never touched OTN in service menu there is no reason to change anything now. You can skip this step!!!!!

  • Access Service menu
  • Enter the Control-SubOption menu and set the values:
  • OTN to enabled.
  • OTN type operating

Caution! RC Keys Up&Down arrows make selections, while Right&Left arrows make changes. You needed to backup previous value before changing any option. Some options cannot be reverted once changed. The service menu has a protected 'advanced' submenu. Press the 0 button four times on advanced to enter the hidden menu. Before touching any setting, please note the original value. The menu settings are listed (with their default values?) in the Service Manuals.

Installing firmware

  • Set dns (depends on you network setup on tv or/and on your router) to:

Develop ip.png

  • Switch tv off and on again
  • Check from tv's menu for firmware update via internet
  • Install firmware if it detects one

Notes:

  • If you get an error at ~90% of install process turn tv off for ~3min and try again
  • If no firmware are shown -> report it (not to Samsung but here in SUPPORT forum)
  • 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)
  • Turn tv off and on again
  • Don't forget to disable further firmware updates!!! (Samsung won't make any technical improvements in new firmwares)

exeDSP Patches

Cinavia logo.gif

A Digital Rights Management (DRM) system utilizing audio watermaking technology created by verance that can detect when an illegal
movie download / pirate DVD is being played on a PlayStation 3 (PS3) console and modern Blu-ray stand-alone players on  the market.
Content protected by this technology carry inaudible codes (the watermark) embedded in the audio tracks by the owner of the copy-
right that indicate how and where they are to be used.

When such a movie is played back on a player with Cinavia detection the players firmware will detect the watermark and check if the device has been authorized for the watermark. If there isn't authorization for the device a message will be displayed saying that the content is protected by Cinavia and not authorized for playback on the device. Cinavia DRM has been added to all new BD players beginning the first quarter, 2010.[1]

This patch will let you playback your *LEGIT* movie copies, without Cinavia interrupting, and is provided for educational purposes only.
We're not at all responsible if your TV/BD explodes!

Instruction

1. Root your device using DNS trick
2. Download firmware from Samsung support page
3. Decrypt firmware with SamyGO Firmware patcher (example): 

SamyGO.py decrypt_all ./B-FIRHRTBEUC

4. Extract exeDSP binary from decrypted exe.img. Here are different ways to do that, you can mount exe.img as squashfs image file or open it in 7zip
5. Open exeDSP in HEX editor and search for hex string: 

10 80 BD E8 08 40 2D E9 04 00 50 E3 00 F1 9F 97

Replace last three bytes (F1 9F 97) to 00 A0 E1. Result must look like: 

10 80 BD E8 08 40 2D E9 04 00 50 E3 00 00 A0 E1

6. Save patched exeDSP
7. To be udated (How To correctly replace patched exeDSP and flash it back to device. Anyone? :))


Patch tested and works well on B-FIRHTBEUC_1016.3. Patch expected to work on all FIR* based devices. Checked on IDA, but not tested on devices yet: 

B-FIRBPEWWC 1053.2
B-FIRHRDEUC-1012.3
B-FIRURDEUC 1012.0
