On first time running the image I need to change provider settings (mobile networks - names accespoints) . the server verification type to "pap and chap" and back to none again, before it connects. But this is to get the 3g connection.
I needed to do this on other rom's / modem.img as well.
The newer modem.img I used was to fix problems with O2 provider users, according to RiseAgainst
If the above doesn't work, can you try the old modem.img
to see if it maybe wasn't such a good idea to change to the newer one.
original modem.img in /system/etc/firmware
I can only test with vodafone provider, so more input on this issue is welcome
