Hacking T-RBYDEUC Firmware - LE40A756 and A856

[arris69]

Hi all!
Can anyone help me with NFS file system on my LE46A956 (T-RBYDEUC). I have already patched my firmware and I have a telnet access to my TV, but I cant find a way to mount a NFS.
...
cat /proc/filesystems
...
I don't see nfs here. Is it normal?

Can anyone help me to setup a nfs client on my TV?

yes, original firmware comes without nfs support, so you need to build the kernel modules.

Is it possible? How can I do it by myself? Can You give me a link to any discussion about building kernel modules for this TV (sh4 CPU).
Maybe anyone already has this modules compilled ?

Arris,
I found kernel-module-nfs package on your website
(http://stb.zsolttech.com/SamyGO-OE.dev/ ... module-nfs)
As I understand this is a kernel module for nfs support and it is possible to load this module and use nfs from TV. Am I right?
I've try to load module (like cifs.ko in SamyGo/rcSGO) but got many errors (dmesg) : -1 Unknown symbol in module

My problem is solved.
I found nessesary kernel modules on Arris website and load them.
So, for NFS support in T-RBYDEUC firmware are needed 3 kernel modules:
1. http://stb.zsolttech.com/SamyGO-OE.dev/?pkgname=kernel-module-sunrpc
2. http://stb.zsolttech.com/SamyGO-OE.dev/?pkgname=kernel-module-lockd
3. http://stb.zsolttech.com/SamyGO-OE.dev/?pkgname=kernel-module-nfs

Unpack packages (with 7ZIP for instance) and get ".ko" files from them.
Copy these files to your USB and load them like described in WIKI:

Code: Select all

insmod sunrpc.ko
insmod lockd.ko
insmod nfs.ko

Now, You can mount shares:

Code: Select all

mount -o nolock IP:/share /mountpoin -t nfs

This works for me in my LE46A956.

First of all You should read this article:
https://sourceforge.net/apps/mediawiki/ ... re_Patcher
use this patch (latest at this moment - v0.24):
http://sourceforge.net/projects/samygo/ ... z/download

After this your TV will run SamyGo/rcSGO script from USB drive at startup.
Read this:
http://wiki.samygo.tv/index.php?title=Samsung_A_Series_(sh4_CPU)_Hacks
Make your own SamyGo/rcSGO script (like usb.sh in WIKI). Use files from WIKI article (blah-blah-blah You can download the whole package here:...)

I have a LE40A856, I have patched for telnet.

Is there a Web browser comptaible SH4?

that can have one with the patch for this tv?

Excuse my English, I went through a translator


Thank you

I don't even know if A series TV's could run a programs/applets. So there is no web app for A series TVs.

Long time ago I wrote here

To end rumors: T-RBYDEUC 1013 firmware does not execute .so games
I studied it in exeDSP binary: an easy patch can reenable browsing SEC_GAME folder.
When you select Telnetd app, instead of loading and executing .so lib a builtin game DBowling is run.
Although dl-load (.so library loader) code is included in binary, it wouldn't be easy to patch missing code back.

It is not true anymore as working library launcher can be patched in. See viewtopic.php?f=8&t=2021
