Hi @all,

i searched a bit for my problem but i haven't found my answers.

I tried to hack my UE40C6800 via Internet@TV widget like it is mentioned in the wiki. But unfortunately my TV got bricked and now it doesn't mount my USB sticks anymore. So i soldered a ExLink-cable (CA42) and set the RS232 to DEBUG. I can see the whole stuff, what the TV is sending out. But my problem is that I can't send any commands. I get no answer to my 10041004. I don't know how to carry on.

I tried it with an old notebook with XP and Hyperterminal, with my PC (Win7 64bit, Putty) and with Ubuntu 11. The same problem at all PCs. What can I do? Which information do you need for helping me.

Thanks in advance.

did you try loop test of the cable? just connect tx with the rx. see if it works.

Hi,

i took a while but now I found my failure. I swapped the pins for GND and TX. Unfortunately i can't flash the partition /mtd_rwarea. Every time i try it the sammy returns the following:

I also tried to flash in Hotel Mode, but it is the same failure. Can anyone help me getting back my USB function?

Edit:
Ok, i found a solution. I disconnected all cables and powered down the sammy totally. After that i was able to flash the partition. Thanks for the hint with crossing TX and RX.
