Yes. You need to decompile framework-res and adjust skate related parameters in xml files under values and xml directories
Use framework-res from working ICS rom as a base for config values.
And check your mic during call - this is often problem when porting ICS roms. Other side can't hear you.
This requires config changes in Phone.apk. Again you must decompile and change values.
i hv decompiled framework-res.apk but i dont know what to do... hahaha!!!!
no mic problem when porting from blade, optimus one or ace, but u'll get the problem when porting from other device.
remember i've asked u all here regarding this mic problem when i managed to port lezo v4.0 to our device. actually i solved it (i mean people at the other side can hear us) by replacing both phone.apk & telephonyprovider.apk from cm9, but i faced another problem, dialer crash!
