From your logs from exlink i am pretty sure your NAND has some problems whether boot partitions or kernel possible are unreadable. Thats why tv goes to bootloop.
Hello again. Only the NAND (oneNAND = KFG1GN6W2D) would be damaged?. The eMMC (eMMC = SDIN502-2G) is fine?

Hey,

I have tried yesterday to downgrade my TV

Model: Ps51D6900
firmware: 1025
DNS IP: 46.101.161.175

But somehow it's not working ;( .... also an OTN reset I have performed

Has anybody an advice for me?

PS: Does anybody has the 1016 firmware for the MSTAR model?
Is there a chance to upload it into the board?

Hi,

New here, first ever post

I've tried today, without success, to downgrade the firmware on my TV

TV - UE46D700
Current FW is T-GAPDEUC 1033.2

Instructions from page 1 of this thread followed
DNS set to 46.101.161.175 on TV
OTN is enabled

I've attempted to change the firmware from Menu>Support>Software Upgrade>Online

I get the message No Software to Upgrade Currently

I've tried multiple times and get the same message each time.

Can anyone suggest what I'm doing wrong please?

That's exactly the same I did but my TV got frozen (and bricked) in the third attempt of downloading.

Hello again. It seems I find someone in my country which do technical TV repair service with a working mainboard for a D6100 (his screen is broken but his mainboard is fine). So maybe we can finally do the job. Does anyone know which programmer could be useful with the KFG1GN6W2D chip and where could we fin its datasheet please? I've been looking for it but I wasn't successful. Thanks in advance.

@juusso

When I try to downgrade,

it flashes on the screen quickly, but the message i get is

failed to connect
error code 606 invalid paramater:
The latest firmware is not yet available.


I'm going to guess UN46d6300 with firmware T-GASFAKUC is not currently supported?

Thanks again


Edit: This should be the samygo supported firmware for this TV

http://downloadcenter.samsung.com/conte ... FAKUC.exe

I would love to see this added. This will help those with UN46D6300 and UN46D6900

Hi. I finally find another mainboard for my UE32D6100, the problem is it was upgraded to T-GAS6DEUC-1028.0 firmware. I tried again to downgrade it using the same Samygo's DNS as always: 46.101.161.175 but with no success. I tried to put this DNS in my router and I tried to put it in my television too, but it didn't worked because the television says there's no internet connection:

I have the same problem than you hica. Can anyone help us please? Thanks in advance.

P.S: Could I use the rooting widget procedure/method with T-GAS6DEUC-1028.0 firmware on this D-series television?

Hello. I've tried the Hospitality mode hack (https://wiki.samygo.tv/index.php?title= ... arm_models) on my UE32D6100 with 1028 firmware and it worked flaweslly. Now I am able to access to the television IP address through FTP on port 21 and I've got an USB source (labeled "SamyGo Virt. USB") permanently.
Now what I would want/need is to mount some shared folders I have on my local network (computers, hard disk connected to a router, STBs...)for watching them on the television directly. I've been looking for this information on the wiki and forum but I don't know how to do it ("SamyGO.sh" or "start.sh" editing maybe?). I've read that NFS is faster and has a better performance than CIFS or SMB. Thanks in advance for your help and information.
