We got somewhere, but then it went bad and after a reboot not only did it not work but wiping caches didn't re enabled GSM. So while we wait for a response by TP for permission and possibly help to dissect his beta 6 ROM which has both fully working CMDA and GSM. I would like to know if you guys know of any other phones that have a GSM Patch that works. Fully.
We know it wont work on our phones hardware. Not yet anyways! Sad truth is GSM seems to be trickier then CMDA which is why all our current ICS ROMs don't support it. Enabling GSM on the ROM will literally edit the Caches as use goes on. Which is why when you reboot clearing the caches works.
If we can find a good patch that works. Maybe we can speed is up faster. You can talk to use on andirc IRC on channel #inc2root.
If you do know any ICS working GSM patches just reply to this post! Thanks!
Also, If you have a logcat.radio of when your GSM stops working that says the following: "E/RILC ( 1312): RIL Response: unexpected error on write errno:9" then let me know,
