Hospitality mode hack for D6 arm models

D6 series SamsungTV only!

Warning!!!

NB. Method is not safe, tested on UA40D6000 and UE40D6750 only, it needs to do more tests. Should work on other D6 series models too.
If bricked - no way back, just Service repair, not possible to repair at home. ExLink could be useful for reviving, but chance is low.
SamyGO does not take any responsibility if TV bricks, hack is available "as is"

Hack needs to be improved - in some cases it can brick TV (e.g. if suddenly disconnected from electricity during boot-up process where start.sh becomes damaged - rare, but possible circumstances!)
New version of hack is available. Discussion and support - here. Thanks!

BEFORE YOU START: Safety measures

• In service menu, enable Debug mode for the RS232 port:

With TV switched off, press the following sequence on the remote:

• UE,LE models:[INFO] [MENU] [MUTE] [POWER]
  
• UN,UA models:[MUTE] 1 8 2 [POWER]
  

Enter the Control menu and set the value of the RS232 mode to Debug.

Once you're back to the main Service menu, you will have to power off the TV for normal operation.

Notice that your TV will reset RS232 mode back to UART when you install another firmware (no matter if it's older or newer).

• Have a working Ex-Link Cable for C/D Series at hand (May help if TV bricks).

If you don't feel capable of soldering such a cable, you can find and buy a cheap (under $5) USB to TTL adapter at eBay.

Supported firmwares

T-GAS*
T-GAS6*

What hack does?

Imports right start.sh and SamyGO.sh to /mtd_rwarea and allows to use SamyGO on latest firmwares.
Also enables SamyGO Extensions start with TV start (no ticker needed).

How to install

1. Install SamyGO using develop account according D series wiki article.

2. Take USB (from now - only 128Mb is required.) (Windows users can use FAT32 formatted USB)
3. Download [D6_Hospitality_v2.0.zip]
4. Unzip archive and you get two files inside, zipped. Unzip. You get:

1_D6_hh_v2.img
2_D6_hh_v2.img

Means first and second image (on second hack version we need two images).
5. Make USB from 1_D6_hh_v2.img using attached Win32DiskImager.exe, or under linux (e.g. if your USB is recognized as sda):

dd if=1_D6_hh_v2.img of=/dev/sda

NB! all data on USB is to be deleted!
6. Power off TV, attach USB
7. Go to service menu (info-menu-mute-power) (or mute 1 8 2 power on UA models)
8. Enable hospitality mode in service menu.
9. Make "Clone USB to TV"
10. Power off TV. Remove USB
11. Make another USB from 2_D6_hh_v2.img using attached Win32DiskImager.exe, or under linux :

dd if=2_D6_hh_v2.img of=/dev/sda

You can use same USB pen you used for first image or you can have two different USB dongles prepared for each of images at once in step 5.
12. Attach USB to TV.
13. Go to service menu (info-menu-mute-power) (or mute 1 8 2 power on UA models)
14. Go to Hospitality mode.
15. Make "Clone USB to TV"
16. Go back to service menu and set Hospitality mode off
17. Restart TV. Remove USB

How to use

Now after you restart TV, you get SamyGO Extensions executed. Limitation - no patches like BigYellow fonts, CHannelInfo and other available this way.
Check wiki article for setup and ussage of SamyGO Extensions.
First sign of success - you get ftp on port 21 and nc shell on port 1023.
