BD-C5300 Firmware Down-grade

[roni71]

Updated firmware on my BD-C5300 from 1024.0 to 1025.1

Since then not playing most of the Blu-rays. Sometimes unable to load and othertimes hangs and don't even respond to any remote button.

Experimented following procedures.

1. Tried to down-grade with both firmware 1024.0 and 1021.4 with USB but got message ?Current firmware is latest Version?
2. Edited firmware 1024.0 using Hex editor. Changed firmware name to 1026.0 and updated date in the firmware. Got rid of latest version message and system started updating. However, after some time got message ?Error in data file?

Need help from experts to down-grade to previous firmware.

Thanks juuso.
Unable to connect to 46.4.199.22 server.
Tried everything; Changed DNS server setting on player, on reuter and on both but no success.
May be missing something. Pls. rescue

I think you are missing a 2 at the end there:
46.4.199.222
That should work
just put that in the DNS settings on your BD player and try and force an update from the settings menu. It should try and load a firmware far above the one you have right now. i.e. 1090.0
let us know how you get along.

Sorry Chaosmaker
That was typing mistake on post by me.
I was using 46.4.199.222 on BD player.
Pls. another guideline.

[chaosmaker]

thats odd, when you use that in your DNS settings of your bluray, what is the exact error message?

[roni71]

Sorry for the delayed reply, was out of town.
Getting following error message:
"System cannot connect to the internet for upgrade. Please check your network setting"
If perform network test get following message:
"The HTTP port is disabled. Please check if the HTTP is blocked by something like the internal firewall program".
Any help in this regard is appreciated

I'm trying to downgrade firmware for my player too (BD-C5900, view topic at viewtopic.php?f=18&t=4683).

I tried to change DNS at Bluray player with the same error (The HTTP port is disabled. Please check if the HTTP is blocked by something like the internal firewall program).

Then I tried to change DNS at modem/router. In this case, the player starts to verify new firmware, it takes a long time then returns to menu without display any message.
