Overview
In the other article I’ve listed the prep steps for to be able to experiment with your Samsung TV.
In some cases, when you do some experiments (all what you do to your TV you are doing on your own risk and liability), the TV might suddenly turn into the “brick” mode, means it is not turning On anymore.
The symptoms of the “bricked” TV are:
- Red dot (infrared receiver) is blinking when you press any button on the remote control but nothing is happening
- The TV screen is black
However it is not completely lost as you might think, and in most of the cases the TV can be recovered to the normal working mode/condition.
In this article we will be talking about how to restore the “Bricked” TV Samsung LE32C530 to the normal working condition, and ONLY if it comes to that mode after you’re experimenting with SamyGO. You may not find any useful information in this article if it’s “bricked” for some other reason.
What we need to get started
We would need the following:
- Ex-Link (RS-232) cable
- PC or Laptop with the USB port
- Telnet Client (Putty – my choice)
- USB Flash stick, the size is not really matter, the matter is – it needs to be formatted in FAT file system
Ex-Link RS-232 cable
There is a lot of different option on internet to purchase the RS-232 cable (about $5-$10), but it can also be made yourself. One of the instruction found quickly on internet.
Telnet Client
You can either turn On the built-in telnet client in your Windows (if you use Windows):
Control Panel -> Programs and Features -> Turns Windows features on or off -> Telnet Client
or download and use Putty (it is my choice).
If you use Linux:
# Ubuntu, Debian
sudo apt-get update && apt-get install telnetd
# Fedora
yum install telnetIf you use Mac OS, you don’t need to install or enable anything, everything should be already enabled in your Mac OS, just open the terminal:
Applications -> Utilities -> Terminal
Let’s get started
The “bricked” TV may become when you experimenting with SamyGO scripts, for example when you’ve made some syntax mistake in the start.sh script.
In such cases, the TV model LE32C530 is not possible to recover in the standard way as described on SamyGO wiki/forums. The only thing from the above recover instruction works is the command 10041004, this command really turns the console into the mode of “commands enter” but this is not enough. There is another working command – CB.
So if your Samsung TV turned to the “bricked” mode, do the following:
- Power Off your TV. To be able to power off your TV in “bricked” mode you just need to disconnect the power cable from the power socket for at least 30 seconds
- Connect Ex-Link (RS-232) cable to the VGA port on the back of your TV, and the other side to the USB port or your PC/Laptop (the one configured with Telnet/Putty client)
- Power On your TV. Connect the power cable of your TV to the power socket. The red bulb should be lighting but not flashing/blinking
- Open the telnet client on your PC/Laptop. You should see a dark or empty screen
- Turn On your TV, using the remote control Power or CH UP buttons. At this moment you should see some listing in your telnet terminal similar to the following (it is just a sample, you might see a bit different listing, depends on the real reason of your “bricked” TV):
================================= Samsung Bootloader Infomation release ver : 1004 Release etc : ================================= UART2 is used to debug mode(0) load kernel start, size : 131072 + 2883584 byte load_cmac()[918 line]: entry->first_blk = 1, entry->no_blks= 1 1024 bit RSA Sign/Verify Test Success. authentication success XIP Kernel Image ...

Authuld is successfully completed. - Here we can see the reason of our “bricked” TV, the line:
insmod: cannot insert '/mtd_exe/samsung_mstar.ko': File exists (-1):clearly says why the TV is not started. samsung_mstar.ko is one of the main executable file in the TV, without which the TV can not be started, so it means there is something that prevents this file be accessible in the filesystem.
- Format USB Flash drive to the FAT filesystem
- Create the following empty files in the root folder of the USB Flash drive:
- emergency_start.sh
- kill_start.sh
- start.sh
These files do nothing, but there is some other system file/process which looks to these files and behaves accordingly when it detects the USB Flash drive with these files on it inserted into the TV on TV start/On.
To make the TV able to recognize the inserted USB Flash drive on TV start/On, we would need to load the USB modules/drivers into the TV system, as we can see from the log listing, the TV system is not loading any USB modules/drivers, which means even if we insert the USB Flash drive with these empty files into the TV USB port, the TV won’t be able to recognize it and do nothing.
The CB command (in telnet terminal) will help us in this case, it will load the USB modules/drivers to the system.
- Take safely the USB Flash drive off the PC/Laptop (with those 3 empty files) and insert into the TV USB port, while monitoring what is happening in the telnet terminal.
- In the telnet terminal type the command 10041004, we should see:
SELP#> - Type the command CB, we should see something similar to:
SELP#> CB ========================================= 1. sync for /core/Coredump.gz ========================================= sync sync ========================================= 2.

Copying is ended... please remove USB =========================================At this moment there were some internal processes running in the TV as well, which we did not even see in the telnet terminal (but they were running, just trust me).
- Power Off the TV by taking out the power cable off the power socket
- Take out the USB Flash drive off TV, but leave the Ex-Link (RS-232) cable in, so we will be able to see what is going on in the TV system logs on our telnet terminal (when TV starts/On)
- Wait at least 30 seconds and
- Power On the TV by inserting the power cable into the power socket. The red dot bulb shall be lighting but not flashing/blinking
- Turn On the TV using the remote control Power or CH UP buttons, in the telnet terminal you should see something similar to:

So what happened when we types the CB command in the telnet terminal? CB command actually initiates the loading of the additional drivers/modules into the TV system, such as USB drivers/modules, and at the same time the SamyGO scripts were activated, which detects the empty files on the USB Flash drive (the TV now sees the USB Flash drive since we have the drivers loaded) and performs special SamyGO TV system recovery operation, that’s how the TV system has been recovered from “bricked” mode to the normal working mode (in the happy scenario).
ATTENTION!
Never ever edit /mtd_rwarea/network_opt/usr/restore/start.sh file in your SamyGO USB flash drive, since it is the only way to recover your TV later on if something goes wrong, this is the file/script which is doing all the magic for recovery.
In case if you somehow edited or broke the /mtd_rwarea/network_opt/usr/restore/start.sh file, the alternative option to restore your TV is to do the following.
As it was mentioned above, the CB command allows the system to load additional drivers into the TV system, such as USB drivers/modules. Then we just need only to create a SamyGO.sh file, put it into the root directory of the USB flash drive. Of course this file has to has some commands in it to do the job, you can use any linux commands which can help you to find the reason and fix the issue, for example:
#!/bin/sh
ls -a /mtd_rwarea/network_opt/As you know (if not – be aware), any *.sh script must have a special top line in it – #!/bin/sh
Don’t forget about it when you will be playing with the scripts.
That’s basically it. Enjoy your recovered TV.
