Rooted Samsung BD-C6900

Post by mirsev »

Hello,

First of all, many thanks to all community for this great research project. I've got Samsung BD-C6900 player. It is NTSC-only version but I have a lot of all-region PAL DVDs. These can not be played now and I wish to remove this restriction. I don't know yet if this is possible but at least I've got root access using Internet@TV hack for C-series TVs with ARM CPUs.

The player does not support ext2/3 filesystem, so I used vfat formatted USB memory and followed instructions from this page. The widget was used from http://www.multiupload.com/OLQTLJ8G52 and the SamyGO extensions were taken here (it is for C-series TV with ARM CPUs.

After configuration the "develop" account in Internet@TV I have installed the hack widget in developer mode and then just started it from Internet@TV menu. The widget installed hack, I inserted USB stick and after checking the hack, files run.sh and ScriptOK appeared on the USB flash drive.

Then I have unpacked SamyGO extensions to this drive and added the following lines in the run.sh file on the USB stick.

Code: Select all

rm -f /mtd_rwarea/profile
$1/SamyGO/rcSGO $1/SamyGO > $1/rcSGO_out 2>&1 &
Now, I need to note that I was also monitoring the serial port of the player, so I could see log messages... After the USB stick was inserted, I saw that it was mounted and then some crash dump appeared. Nevertheless, the SSH connection to the player succeeded and I've got root access.

Later, I have modified SamyGO/etc/rc.sysinit script: all modules related stuff was removed, and only $SYSROOT/etc/init.d/03_03_sshd.init was started. With these modifications everything works without any crash. The modified SamyGO/etc/rc.sysinit script is here:

For those who are interested in - /etc/init.d/rcS from C6800:

USB mount is handled by binary files, not shell scripts, so it is impossible to make a modification which allows to run something as run.sh script. I'm still looking for the possibility for permanent chrooting, but haven't find anything usefull yet.
Are you sure that hardware is indeed similar? It might be that your player has Broadcom chip (MIPS based, not ARM). Please, check /proc/version and /proc/cpuinfo If it is MIPS, then it might be similar to B-series TV.

How did you get the access to shell?

WARNING: New 1021.2 firmware contains updated versions of hotplug and usbmount scripts which will disable SamyGO extensions on a USB memory. So, if you need to keep SamyGO extensions working (to access the player through the network and run custom scripts), don't update firmware to the version 1021.2.
