Hi all, i?ve got the same issue, as "sapro", code 603. UE40D8000, T-GAP8DEUC-1024.1. Any suggestions what am I doing wrong? I also tried to upload an older firmware by usb, but the tv doesnt recognised any firmware on my flash disk... Help will be regarded!!

i thing your good firmeware is the 1025.1 from usb stick, no 1024.1 for your UE40D8000

Hi! I have a UE40D7000 with firmware T-GAPDEUC-1023.1 and i cannot downgrade. I know i don't know much about downgrading but I tried and told me "failed to connect error code 603 invalid parameter the latest software is not yet available".
I'll post some screenshots with my issues...
Some advices?

Hi Sapro
Hi olivermolnar

I think you erred in your DNS address. Your address must be the same as your gateway address. 192.168.0.1. Not 46.4.199.222.
Change this. Menu -->network-->status of the network-->IP setup -->DNS Mode --> Auto
46.4.199.222 is address to downgrade your firmeware to 1015, to intal SamyGo. Read this topic

I tried with Auto and still doesn't work, error 603.
I even changed DNS (with 46.4.199.222 as asked in the frist post from this topic) in wireless router configuration.. and nothing.
I tried 3 months ago to upgrade by "Online" with the original Samsung firmware and I got the same error, 603. Now I want to downgrade in order to install SamyGo..
Any useful tips?

I just realized my mistake. I used the DNS developer. whereas it takes, use internet DNS menu. sorry for my stupidity.You been in the real.
I have the same error 603.
Can be is the router that causes this error. I'have a LiveBox ( french provider :Orange)
