Hacking TV over Hotel mode (most C series models)

Universal USB disk to hack C series TV. It should work on any C series TV with export settings to ext3 USB support. Some models does not support ext3 file system for settings export (C6000/C630...firmwares with T-VAL6DEUC) Tested and works on models with T-MSX5DEUC, T-TDT5DEUC and T-VALDEUC (until 5.1.2011).

After this hack you can connect to TV over telnet, you get CIFS (samba) and NFS support. Moreover, if you attach USB with script file "SamyGO.sh", it will executed.

This hack has unificated structure for comfortable script execution for developers (read below)

Preparation

Only for USB, recognized as sda.
How to check. Read this post. Later limitation will be removed.

1. USB > 1GB space. (windows user can use Fat32 formatted USB)
2. TV in normal mode. Export channels from TV to USB
3. Activate Hotel Mode

Mute-1-1-9-Enter
set to on by pressing "left"

4. Export settings from TV to USB
5. Save files you get anywhere in PC
6. Download file, extract from archive. You get 1Gb file network_opt_28.12.2010_3_sda.img
7. Make USB from this image with included win32diskimager.

• Under windows you can use win32diskimager.
• After win32diskimager finishes, USB is not accessible under Windows, because it is ext3 format.

Hack TV

If you have linux and TV is not hacked

8. Attach USB you made to linux PC. Copy channel settings file (you made in normal mode) to root of USB

9. Rename file (channel_list_LE32C550_1001.scm for C550) to zip

channel_list_LE32C550_1001.scm.zip

10. Add directory usb_mount with empty file in it (e.g. 1.txt; - very important) to archive
11. Rename back to channel_list_LE32C550_1001.scm

• You get files inside of archive:

 Archive:  channel_list_LE32C550_1001.scm

12. Copy files exported in Hotel mode (only files, without directories) to /restore directory on USB

• Exported in HotelMode files to copy:

• Whole USB structure you have to get

13. Exit from Hotel mode:

• Go to ServiceMenu

Info - Menu - Mute - Power

• Hotel Mode ->Off

14. Attach USB to TV and import channel settings to TV. Everything must go w/o errors.
15. Activate Hotel mode again 16. Import HotelMode settings you exported before (as is, with directories)

17. Press OK.

18. TV restarts twice and starts in black screen. DO NOT POWER OFF, DO NOT DISCONNECT USB.

• Wait 3 minutes. After trhee minutes or if you get to console earlier you can reboot TV.
• Try connect to TV over telnet (port:23)
• If you get to console, congratulations.
• TV starts in Hotel mode. If you have your channel settings right, you can deactivate hotel mode from service menu.

19. If you haven`t got your channels back and if you can`t telnet to TV, it means - something went wrong

• Look for file first_run.ok and content of directory /result on USB

20. If you have telnet after hack, execute:

cp $OPT_DIR/usr/restore/start.sh /mtd_rwarea/start.sh

Ways to unbrick TV

If you do not have success or script finishes with error, or you have hacked over Widget and it stopped working (on latest firmwares), Format /mtd_rwarea over ExLink:

• Make Ex-Link Cable for C-Series attach to TV.
• Power off TV.
• Unplug Network cable, might antenna too. Leave only ExLink and Power cable plugged.
• Power on TV.
• Open terminal and connect TV over ExLink.
• Enter commands following by Enter:

10041004
81588
20089999
2
0
0
2 (advanced)
2 (DeviceManager Debug)
90 (DeviceManager MW Debug)
12 (DLNA, FLASH, ODD, HDD, MoIP Test)
11 (FLASH, HDD Format Test)
10 (or another, /mtd_rwarea/ partition number (14)

On the last line you have to enter number of your /mtd_rwarea/. On C550 it is 10, but on other TV it can be other (e.g. 14)

Try hack TV again from step 7.
