My connectivity randomly cuts out - and after searching the CM9 discussion threads - I understand my modem is likely incompatible with my region.

I couldn't find a sticky or thread in XDA about recommended modems by geography - so I was hoping to get some advice here from your experience.

I have a Galaxy S II.

    I think you might need to let us know which device you have before anyone can recommend software for it. – GAThrawn Jul 6 '12 at 10:13
  • Which model is it? i9100G or the original i9100? Both have very different internals, just be aware of that. – ce4 Jul 26 '12 at 23:24

Identify the Correct Modem

The Galaxy S II modems files usually contain a reference to the zone where they best apply. In your case, the first reference letter should be "J", that appears just after the phone model.

Official Firmware: July 2012

Middle East

  • United Arab Emirates XSG - I9100JPLPF/I9100OJPLPC/I9100XXLPX ICS 4.0.3
  • Israel Cellcom CEL - I9100TJIKG3/I9100TCELKG3/I9100TJIKG1

You can also find out your modem version by accessing the "About phone" menu option. The value of "baseband" is your modem version.

Modem File

The file Modem_I9100TJIKI2.7z should be the most appropriated for your location.
