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 &
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:
