After a week of gnashing of teeth and scratching of heads, I have a rooted M130 Casio Gzone Commando. I found a file (/system/etc/init.qcom.sdio.sh) that was rwxrwxrwx.
First, I made a backup of the file to my sd card.
Second, I turned wireless off
I then edited it with root explorer and added at the bottom just above "exit 0" the following lines:
chmod 0777 /system
chmod 0777 /system/bin
I edited it with root explorer by first adding the commands above then saved the file. I noticed it made a backup so I edited it again by adding a "1" after the "#!/system/bin/sh" on the first line and saved it again. Finally, I remove the "1" and saved again. This process may not be necessary, but sometimes I have seen where a backup might try to load.
After this I rebooted and found that the /system and /system/bin folders were now read/write without superuser.
I used adb to push su (I used the su file from zergRush, however you can use the one from the link below) to the /system/bin folder. Alternately you can do this from your phone by using a file explorer to copy/paste from your sd to the /system/bin folder
I checked with root explorer that su was, in fact, in the /system/bin folder. However, its permissions and ownership were incorrect.
I went back to the /system/etc/init.qcom.sdio.sh file and below the lines I added earlier I added the following:
chown root.root /system/bin/su
chmod 06755 /system/bin/su
I saved the file three times like above and then rebooted.
I went into root explorer and verified the ownership and permissions of su. They were correct.
After that I installed superuser and busybox installer from the play store.
The M130 was officially rooted.
As a precaution, I removed the lines I added in the /system/etc/init.qcom.sdio.sh file and returned the permissions and owners for /system and /system/bin back to their original settings.
Finally, I updated the recovery to GNMs all in one recovery for the commando from
All In One Recovery Thread
*I highly recommend you install the GNM recovery as soon as your rooted and do a nandroid backup BEFORE you start freezing and removing bloatware. In this, you can always return to an operational commando if you fudge something up....experience is the best teacher.
