[Galaxy S III Q&A, Help & Troubleshooting] abunene:
Unable to connect to mobile networks (no signals)

Hi guys I could not connect to any mobile networks at all since flashing rootbox 4.0 above, I have tried full wipe, flash back to stock rom, unroot and root again but still cant fix the problem.

It seems that this issue also happen to me on other roms such as latest paranoid and pac rom.

Also I noticed that air plane mode on and off itself whenever i bring up the power menu to observe.

Currently Im using rootbox nightly 20130323 and it works fine.

Please could anyone help me with this I really wish to try out the latest features

I have attached my logcat of the problem occured below, hope it would be helpful, thanks!
