Hello to all. First of all excuse me for my bad English. I'm from Spain and I'm trying to improve my English level everyday. I haven't find any place in the forum for introduce myself so I'm taking advantage of it to do it now, it's a pleasure for me to be here with you. I wrote this message because I had a big problem today. I have a UE32D6100 Samsung television with T-GAS6DEUC-1017.1 firmware (I had a LE40C650 too but with this last television everything is fine). I've been reading a lot of this forum since one week in order to try to hack both televisions. I decided to start with the UE32D6100. I entered in service menu and disabled watchdog and enabled the RS232 option as "Logic" instead of "UART" (by default). I forgot to clone the settings to an USB and I didn't make screenshots of every screen of the service menu, but I did a photo of the "main" service menu screen:

So I decided to downgrade my 1017.1 firmware (using the first message of this post) in order to hack the television with the developer account (
https://wiki.samygo.tv/index.php?title= ... cpu_models) because it seemed "easier and cleaner" to me than the hospitality mode (
https://wiki.samygo.tv/index.php?title= ... arm_models). I hit the menu key and then changed the DNS IP of my television to 46.101.161.175. Then went to the option for upgrading the firmware "by the official way" and started to search it. I forgot to say that the OTN option was enabled and set to "Operating" the last time I entered in the service menu. The first time I got a message from the television that told me that there aren't new firmwares found ("No se ha encontrado software para actualizarlo" in Spanish language):

I tried another time and then I got a 606 error message. I tried one last time and then I got the same message than the first time ("No se ha encontrado software para actualizarlo" in Spanish language). Then I realized that the TV stopped working. If I push any key in the remote control nothing happens...So I waited 5 minutes and then I unplugged and plugged the power cord. Now the problem is the television doesn't work. It's in blank (or black screen better) with no audio and no picture. I uploaded a video to Youtube to show you it better:
https://youtu.be/XJsyhNlTme8Then I tried to do a "blind factory reset". I powered on the television and pushed the "EXIT" key for 15 seconds. Then I pushed left arrow key (I tried later with down arrow key too) and hit "ENTER" key, but nothing happened. So I tried to power off and power on the television again and try with the "INFO+MENU+MUTE+POWER" conbination to access the service menu and then hit "ENTER" three times (to go to "Option" menu, "Factory reset" and then confirm it) but nothing happenned five minutes later.
At this point I think I had two options but I don't know if any of them would work. The first option is to do an EEPROM reset but if I do this I will lost all the service menu configurations, so I would prefer to try the Ex-link cable first and if this one doesn't work then do the EEPROM reset.
The problem now is I thought my Ex-link cable would work fine but I think I made a mistake and now I will tell you why.
I had a CP2102 serial to TTL converter which I bought in eBay some years ago. With this module I was able to "revive" some routers with the serial connection and PuTTY. I connected the +5V of this module to a red wire of an USB cable attached to TV. I connected the RX pin of this module with the RX pin of the VGA connector I bought after soldered it and I did the same with the respective GND and TX pins (GND and TX pins of the VGA to GND and TX pins of the CP2102 USB to TTL module converter or adapter like this:
https://wiki.samygo.tv/images/0/06/VGA-Exlink.jpg). Then I connected the VGA connector to the VGA port of the television and by the other side I connected the USB port of the converter module to my Windows laptop. In my Windows laptop I had PuTTY properly configurated with the right port, speed, etc... in COM4 (the connection for my USB module) port as a serial connection like this:
https://wiki.samygo.tv/images/d/d2/ExLi ... tings1.png . The problem is nothing happens in PuTTY when I switch on the television. I already tried with an VGA and/or USB extensor and unplugging the aerial/coaxial antenna cable and the LAN ethernet cable too but I got the same result...Here are two photos of my Ex-link cable:

Where is the mistake? I used this CP2102 adapter because I have no MAX232 circuit neither and USB to RS232 serial cable or Nokia CA-42/DKU-5 USB cable. Is my Ex-link cable right or is a pice of garbage/rubbish?
I can't understand how is this possible. I've been reading days and days of documentation in this great forum/wiki/website and I think I learned a little bit in order to avoid this specific situation but as you can see it seems this was impossible...I also can't understand how is possible to brick this television using the "fake DNS firmware downgrade". I am very sad with this situation. Could anyone help me plase? Thanks a lot in advance and sorry for my very big and long message.
