Here isn`t any other. Either it works, or it doesn`t work. That`s all.

Hi, I trying to downgrade my tv ue40d8000 with firmware 1033. I tried with the dns here posted but I get error code 603: Invalid parameter.
Could someone help me and tell me where I can get more information? The reason for the downgrade is because I want to install Oscam.

Thank you very much.

Don't bother, no Oscam on D arm :)
I do NOT reply to any question by PM. Please use forum.

I found a tutorial on how to install Oscam in the D / E / F / H series. But the first step is to make root on the tv to be able to access by FTP.

Hi,

The downgrade issues you are facing are not related to DNS at all. The 46.101.161.175 DNS server works correctly and resolves samsungotn.net to samygo.tv server.

The problem is an error in samygo "samsung otn proxy" web site:
Warning: fopen(/srv/http/infolink/tmp/PHPError.log): failed to open stream: No such file or directory in /home/arris69/SELPClasses/Helpers.inc on line 64

I am attaching sample request/response. Looks like the downgrade service is doing its' job perfectly, but those PHP warnings are emited dirrectly to API responses. The warning messages mixed with XML response make it invalid. So on SmartTV process endsup with Error code 603 on screen.

Let's hope guys at samygo.tv read this thread. So they can take a look at Helpers.inc line 64 and figure out problem easily.

Code: Select all
