Hi!
I have a BD-D5500Series_ZF
FW: HTB-D6500EUB-1014

I've been trying to downgrade to version 1012, but with no results.
Like "memory", i applyed your DNS, but no "upgrade" available.
Any help please?
Thanks!

before i go crazy, pls. check to what firmware -class your device belongs!!!!
like user here: viewtopic.php?f=18&t=4244&start=10#p32606
visit http://www.samsung.com/ search for your device and check what's the firmware filename.
postings without this information will be ignored.

Hi,
I see that you're fast solving problems

I tried to downgrade for BD HT-D5530 (current version 1014).
It was downloading your firmware, but reaching around 80%, it keeps retrying the download from 0%. After several loops, I got error 800 (resources error).
Then I tried to turn off/on my device, also I tried cold start, but still the same error.

I saw that it was trying to get the version "1112" instead of "1012".. is it normal?

Thanks!

Thanks!

yes firmware was 1012.2.
hm, we moved the files around maybe it needs some changes in timestamps. can you reset your device pls. (press EXIT button for ~15 seconds) then set dns and coldboot again.

thnx
