BD Firmware Downgrade (SamyGO Proof of Concept)
Re: Firmware Downgrade D-Series (SamyGO Proof of Concept, BD
BD-D5100 update:
The BD-D5100 requires a certain domain to resolve BEFORE the upgrade server is contacted. Here is the log of HTTP requests made using standard DNS:
[site blocked: http://www.samsungotn.net] from source 192.168.1.122, Thursday, June 21,2012 22:10:56
[site allowed: m.icq.com] from source 192.168.1.122, Thursday, June 21,2012 22:10:44
[site allowed: http://www.icq.com] from source 192.168.1.122, Thursday, June 21,2012 22:10:43
Note that the ICQ resolve is required before Samsung is contacted.
If ICQ is blocked, or down, the BD-D5100 tries another domain:
[site allowed: http://www.internic.net] from source 192.168.1.122, Thursday, June 21,2012 22:14:55
And if that is blocked:
[site allowed: www.yahoo.com] from source 192.168.1.122, Thursday, June 21,2012 22:24:28
(it also tries these in random order)
I believe
The BD-D5100 REQUIRES DOMAIN NAME RESOLUTION
before it attempts to contact http://www.samsungotn.net.
Therefore, arris69 (if possible) should modify his apache (using a simple .htaccess file, or firewall chain rule) config to resolve all DNS requests to his "www.samsungotn.net" server, OR, modify all requests BUT "www.samsungotn.net" to an empty HTML file/directory.
I am going to assume that more BD units in the future will work like this, resolving domains before allowing upgrades. Luckily, it's a simple fix.
Thanks again arris69!

the device has smarthub? are you sure that no icq widget is installed? are your 100% sure requests came from bd-device and not from other computer?mrlumpy wrote:BD-D5100 update:

this won't work. what you can do is maybe some NAT rules or host defines on your routerI believe

can you make some network-traffic dump (maybe with tcpdump?)I am going to assume that more BD units in the future will work like this, resolving domains before allowing upgrades. Luckily, it's a simple fix.
Thanks again arris69!
like:
Code: Select all
tcpdump -i <correct nw interface> -e host <ip of bdplayer> -s0 -w out.cap

Hi arris!
Thanks for the response.
The DVD-D5100 is at my mother-in-law's, connected to a standard netgear router. No editing of DNS entries is possible, it's standard consumer stuff. Hence why I used your DNS server.
Perhaps wireshark on Win7 may work though to do a TCP dump...
I'm going to try and see if there is a public editable DNS service that will allow me to redirect www.samsungotn.net to your custom server, I'll let you know how it turns out.
Thanks,
mrlumpy
PS The D5100 uses DNLA / AllShare (on your windows box), there is no "smart hub" option or button.

Re: Firmware Downgrade D-Series (SamyGO Proof of Concept, BD
Worked on BD-D5500, thank you very very much
Can someone please tell me how to disable the auto firmware update on the BD-D5500, I've switched off "update in standbye mode" from within the settings but it still keeps asking and then trying to update to the latest Samsung Firmware.

if you don't know how to access the service menu then you never turned it off (logically). per default it's enabledmafgr wrote:Do we need to enable OTN in our BR players??

on some devices yes on some not. pls. report what's on yours. but if you make a factory reset (read manual of device how to do it) it "should" show the correct version (1015.?)arris69 propably i cancelled the update i have the 1025.0 and today i shall be ready to test it.

not really helpful the modelname, then from my point of view there are just different firmware-classes like B-BRCMBSP B-BRCM53BSP B-BRCM65BSP etc.Can you please help me out??
