I have no fear of that, I do TV service,I have all the programmers including BGA chips.Your problem will be KFG1GN6W2D.
Understood Michal. Thank you a lot for your support. Do you know if my current defective KFG1GN6W2D chip could be repaired extracting it and reprogramming it or should it be replaced with another new one? I understand then the SDIN502-2G is intact.

As I previously told here:
viewtopic.php?f=22&t=4199&start=270#p100850

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 (I don't know what is the code to post Youtube videos in embedded mode in this forum, sorry):

I'm from Spain. What do you mean with "swap"? Where can I buy it programmed? Has this chip to be programmed with my television model specifically or could it be with another different model? Thanks in advance for your help.

in my opinion
Is firmware the same for D series 6 .... For series D 5 .... it's also the same.

Just beware that D55xx/57xx/69xx are MIPS/Mstar whereas "others" are ARM/Samsung :)
I do NOT receive any PM. Please use forum.

Hello again Michal. When I tried to hack my current bricked U32D6100 I read the D Series Wiki (https://wiki.samygo.tv/index.php?title= ... eries_Wiki) in order to choose the better method to apply. In the wiki you have three (3) possible/available methods to use:

1) Root access for D series Mstar cpu models (D55xx-D57xx, D6 series plasma TV)(https://wiki.samygo.tv/index.php?title= ... cpu_models): this method didn't apply to my U32D6100 because it is an ARM model.
2) Rooting D series arm cpu models (D6xxx and above, older firmwares) (https://wiki.samygo.tv/index.php?title= ... cpu_models)
3) Hospitality mode hack for D6 arm models (Also for latest firmwares! Fast autostart. Not for D7/8). Later support of D55xx/D57xx will be added. (https://wiki.samygo.tv/index.php?title= ... arm_models)

I tried the method 2) because it seemed easier and cleaner than method 3). The problem was I had 1017 firmware and I read somewhere that this method would be successful for firmwares than are older than 1016, so I though that would be a good way to downgrade my TV firmware first using the Samygo DNS 46.101.161.175, and after that apply method 2. Then my brick appeared after trying this...

I follow my "investigation" and I've found more interesting forums where I try to find more information about the possibility of avoiding all the mainboard replacement and replace only the damaged component of it. It's curious because all of that come from Russia:

http://www.ejtag.ru/viewtopic.php?f=18& ... D&start=50
http://monitor.uxp.ru/forum/viewtopic.p ... 30#p185361
http://tel-spb.ru/remont-tv-lcd/samsung-ue40d6100swxru

On this last link I've found a file which is "something I don't know" (http://tel-spb.ru/remont-tv-lcd/samsung ... U_H308.rar).
This file contains 3 .bin:

24C02.BIN = 256 bytes.
24C512.BIN = 65536 bytes.
WT61P805.BIN = 65536 bytes.

Maybe it's only the EEPROM? Now the question is if "this" would be compatible with my television. My television is UE32D6100SWXXC (Version No 04) made in Slovakia and the posted on that website is "SAMSUNG UE40D6100SWXRU Ver: H308, Main: BN94-05368B BN41-01604C, Panel: LTJ400HV06-L". I don't know if this firmware file could be "adapted" to my oneNAND = KFG1GN6W2D. Maybe some changes would be necessary to apply in service mode in my television after flashing the oneNAND. Anyone could help me please? Thank you again for all your support.

if it were Weltrend I know from experience that neither the LED does not come on you.But everything is possible.If they were an eeprom, I could have sent you the programmed ones.You would have exchanged yourself too.
