[General Questions and Answers] orium:
I'm trying to root my device without success. The device is a Gemini Joytab 9.7 GEM10312G with Android 4.1.1.

I'm trying to use the method described here: http://xdaforums.com/showthread.php?t=1886460 which exploits this bug: http://seclists.org/fulldisclosure/2013/Jun/115

I got to push the 'ro.kernel.qemu=1' into /data/local.prop using the restore bug but when I reboot the device and I open a shell with adb shell I can see that I'm not root (uid = 2000):

$ cat /data/local.prop

cat /data/local.prop

ro.kernel.qemu=1

$ id

id

uid=2000(shell) gid=2000(shell) groups=1003(graphics),1004(input),1007(log),1009(mount),1011(adb),1015(sdcard_rw),1028(sdcard_r),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats)

Maybe the adb bug is solved in this release? Any suggestion to get root on this device?

The device is not very common so it has no much info available. I get this info from /system/build.prop (maybe it can help to point to another rooting method). Thanks a lot.
