[Q] P769 Call Problem
The phone works good initially, but once I move out of Wifi (so that phone's data connection takes over) and move back in, calls stop working. No incoming calls, no outgoing calls. data, incoming texts all work fine. Just no calls. I even get the text from the service provider that I missed a call.
This happens in stock 20d, 20f, 20h, and CM10.2.
Has this happened to anybody else? Did the delay in installing radio_fix (see below) caused the problem?
Long version (history):
I used carloswii5's method to unlock bootloader (http://forum.xda-developers.com/show....php?t=2277639
), and load CM10.2.
At the end of the method, I forgot to install radio_fix and used the device for a couple of hours, all the while wondering why the radio seems very weak and why I am going in and out coverage in the middle of this metropolitan area.
I eventually realized that I forgot the radio_fix.zip and installed it. The phone started working properly at that point, with signal levels comparable to other phones.
The trouble starts when I move out of Wifi area and THEN MOVE BACK INTO (OR MOVE INTO SOME OTHER) WIFI area. At that point, I am unable to make or receive calls. Outgoing calls do not result in any tones at all. Incoming calls get a number-unobtainable tone (beep beep). It doesn't matter if I then turn off the WIFI. The calls will not restart until I restart the phone.
I then went to CMahendra's CWM backups thread (http://forum.xda-developers.com/show....php?t=2136204
) and installed 20d, 20f and 20h one after another, and then back to CM10.2 The exact same thing happens in all the versions of stock and CM.
I am on Lycamobile. Stock versions recognize the SIM correctly as Lycamobile while CM10.2 thinks it is T-Mobile. It doesn't matter though, since both the coverage and eventual issue of 'no calls' is the same in both versions.
