[Samsung Gear S2] adfree:
EPK5 have less root permission... with my method... :rolleyes:

sdb shell
sh-3.2# dd if=/opt/usr/media/Others/rootfs.img of=/dev/mmcblk0p13
dd: opening `/dev/mmcblk0p13': Permission denied

Hmmmmm...

I have to rollback to AOJ2 Combination Firmware... to change something...

Hmmmmmmmmmmmmm...

Maybe I will then better try also BOKK2 Firmware... to "enjoy" the evolution of Samsung Security protection... :rolleyes: :rolleyes:

Meanwhile I have added all my changes which I need in rootfs.img to Batch file *.bat

As I am using my Tizen SM-Z130H handset for modify rootfs.img, at the moment it looks like this:

Maybe later I could add files too...

Need first to test.. if I have not again something forgotten. :D :rolleyes:

Best Regards

Edit 1.

Interesting...

Reboot work... I have forgotten if reboot Command also work in non rooted Tizen Firmware but here in my EPK5 this not lead to Download Mode:

sh-3.2# reboot download
Failed to write reboot param to [B]/run/systemd/reboot-param[/B]: Permission denied

Okidoki,,, so I have to press the keys to flash AOJ2 Combination as base... before I can proceed with stupid tests... :cowboy:
