I can confirm on my non rooted commando that file is writeable. Inserted the chmod commands into the file, adding one for the /app directory, and I can delete .apk files from the app directory as well as copy them from the sdcard back to the app directory. I can also write a random sound recording i had laying on the sdcard to the app directory. Now .. how to root fully so I can uninstall these abominations of bloatware that was included ive been having to look at for a year now.
Also It did not affect my wireless at all, I can enable and disable it and connect to wireless. Data is working as well.
