TV D-Series Firmware Downgrade (SamyGO Proof of Concept)

[qokisdan]

Hi all
Same issue here... I downgraded 13 days ago with no issues but had to upgrade again due to a Samsung tech call out because of a faulty panel display. Anyway I can't downgrade again and get the same 603 error message. The Samsung tech did not do anything to the settings he just came and assessed the problem and said they would have to order a new panel (2-3 weeks) so I'm not sure whats happening here. Could the servers be down?

Is there a way to downgrade using a USB pendrive? That would be really useful.

for sure: "zero firmware" for d-series.

dunno what samsung service partner will "release" it here...

Hi there.
I had the same problem - error code: 603, but then one day my TV alone drew a message that the new firmware is available and whether I want to download and install. Of course I downloaded it, but when it started to install it gives me an error that the installation can be done and to try later. Of course I tried again several times but always the same. The next day, when I try to update my firmware shows that the new is not available.
Will try again, hoping to get more sometime.

Greetings to all!

It would be great though.

Hi keletanew
What is the actual error message... is it 'error code: 603 Invalid parameter'? maybe not as you where able to start a download and most of us on viewtopic.php?f=24&t=4531 are unable to.
