I think you don't understand my post.
Since I don't have your TV, I cannot know the exact commands.
You don't give us any info about it. like df output or /dev/ directory listing...
So You needed to find by yourself.
login to shell of tv and
As it writes in wiki there is 3 commands to dump the TV flash devices to usb flash.

Code: Select all

bml.dump /dev/bmlxx /dev/usb/sda1/bmlxx 

Code: Select all

dd if=/dev/bmlxx of=/dev/usb/sda1/bmlxx 

Code: Select all

cat /dev/bmlxx > /dev/usb/sda1/bmlxx 

each command could copy your on bmlxx device to usb.(xx needed to be number)
Some models doesn't have bml.dump command. Try others than.

You needed to capture entire flash dump to USB. I mean every device (/dev/bml0/x or /dev/tbmlx or /dev/stl0/x... it varies depending on your TV's structure)...
After you/we can inspect this files and try to found solution...

I think there is no easy way than.
If device is actually CI+ and if Serial not working. How can we read and dump firmware?

From terminal (ExLink cable)
Please try to enter '1198282' numbers twice instead of debug string. Is it shows a menu?

The last hope for those devices that, writing an application similar to Telnet Application for execution at TV that dumps the flash.
Is TV supports gadgets? Is there a menu exist as like content menu at higher models?

If TV cant run external application too. Than there is no way to enter to shell and read firmware with known methods.
Might be some B530 owner electronic hacker who has ability to solder and read his TV's NAND chip physically from on board.

my tv le37b530 dont have rs232 port conector only usb port service . in this case how i can capture the flash dump?

There no rs232 "port" on my TV too. But ExLink cable, which is compatible rs232 protocol.

sorry i writte wrong . i dont have 3.5mm port on my tv(service)

Weird. Really. So you are out of luck.
Might be again could do something by yourself. At B650's, there is another serial port header at board.
But this require opening your TV's back and need to know what you are doing.
