[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] TheNavi:
First, the format /system/ thing, reflashing CM and gapps fixed absolutely nothing.

Second, yea I thought thought so. I tried su but I don't think it actually switched to root. When I used a root checking application I found out that it's not properly rooted. After checking your thread's first post I found out that root is disabled by default. I enabled it and the multisim command worked.

Let's go back to the network issue.

That's what logcat prints.

That was a few moments after the GSM/CDMA thing. I guess I'm stuck.
