Sorry Lucas, I'm tired and didn't see the new page on this thread. So, I hopened a new thread.
I suppose that's autorun.sh that don't run, but not sure.
I have to put a trace in this script.
Actually I have trace only on MyScript.sh and I don't see it after installation.
EDIT : I modified autorun.sh
Code:
>/mnt/onboard/.kobo/autorun.log
/mnt/onboard/.kobo/MyShell.sh
rm /root/autorun.sh
sync
reboot
The autorun.log file doesn't appear in /mnt/onboard/.kobo/. So, that's /root/autorun.sh wich isn't launched after installation of the plugin.
