== Enabling serial input and recover your TV from bricked hack==

* Enable '''[[Ex-Link Cable for C/D/E Series and BD players#Enable Debug mode in service menu | debug mode in service menu]]'''
* Build '''[[Ex-Link Cable for C/D/E Series and BD players | ExLink cable]]'''

==Navigate to required TDM submenu==

The codes mentioned below are often device (and firmware) specific, so you may need to check for the correct codes specific to your model. 

*Connect your communications software and open the serial port
 I usually use Mac. Even I could open the port and I could see the info from the TV I couldn't interact with keyboard.
 So I decided to use ''HyperTerminal''. The old Windows built-in communications software.
 Windows 7 does not include this software, but you can download it from the web. Just Google it.

*Turn on your TV set, if everything is connected like described at the steps before the serial log should be shown at the serial terminal.
*The TV will keep on sending info, but when the debug log slow down a bit, send next command.

*Enter '''10041004''' (when typing the digits '''No Input is shown''' at the serial terminal) and confirm with '''Enter'''.
*In my case the SERIAL INPUT MANAGE was activated just pressed 10041004. No ENTER was needed.

after that you should see:
<pre>
[SERIAL INPUT MANAGE] serial input ENABLE!!!!!
</pre>

*Now enter '''81588'''
*You will see this:
 Aleady made Scenario File...so delete file
 @@@@@@@@@@@ Key Record Start @@@@@@@@@@@

*Now enter '''20089999'''

*Now your system is clean. On next reboot your TV will regenerate that partition, and your devices will be mounted again as before.
*Now you've learn this lesson, you can hack your TV again :)
