Settings crashes after APN modification

[fabioangellotti]

Hallo everybody, I have a device running Android 4.0.4. I have modified the APN tab but now everytime I try to go back to it, the process "Settings" crashes...This means that I can't access any longer the APN tab!

I have tried to use the APN backup & restore app as suggested in other threads, but with Android 4.0+ it is not possible to modify APN settings with third party applications.

Thanks for your support.

I haven't hear this before. Have you modified the phones software?

Otherwise I suggest that you repair the phone software using PC Companion:
