I think it's time I turn to the forums with this issue if I'm ever gonna get GAOSP fully working on my device.
BEHAVIOR: The two latest Nightlys I've flashed have given me a 3g-symbol and working connection on either the first boot (without gapps installed) or the second, after installing gapps. The problem is that over consecutive reboots (to change themes, settings, just to try etc.) the 3g-data rarely returns. I have been rebooting the device for 20 times in a row without getting it to connect to 3g-data. Using the *#*#INFO#*#*-menu and "enable data connection" doesn't work. Changing to WCDMA-band only may help with frequency of working reboots, but it's hard to tell. Some times (on some combinations of ROM/baseband) switching airplane-mode on/off has worked.
OBSERVATIONS: What I have observed is happening is that whenever 3g-data isn't working, the APN-list i empty. If I create a new APN it will not show after I have pressed save. If I reboot until i get 3g-data again, the new APN will show up together with the original ones. I've had this problem occur with many different ROMs from what I can remember, but to vastly varying extents.
There seems to be some connection to baseband too, because even on galaxo 1.6.3.4 I've had lots of problem with anything newer than II5, or even newer than IH8 to be completely stable, until I used jakax 3g-fix: http://androidforums.com/samsung-i7500/152849-fix-3g-umts-network-interruptions-donut-jc6-amss.html. Since then I have been using JC6 with Galaxo 1.6.3.4 and only losing 3g-data on 1 of 5 reboots or so. jakax's fix Isn't for this problem though, so I've no idea why it helps!?
MISC: I've heard some others having similar problems, but most seem to have been solved in some update or they sold their devices or something, because no thread has come to any solution really. My device was one of the first and bought from Germany and is being used in Sweden, could this affect it it any way? I have seen some threads of problems with android APNs disappearing when certain MNC-numbers are entered, but I never found any explanation or solution there either.
So, if you recognize any of this, or have an idea of what may be causing the problems, please help me because I'm scared of that when GAOSP is finally stable I won't be able to use it. If you read this jakax (or anyone who knows what his files actually does), please try to see if there is a solution to this problem somewhere within them. All help is much appreciated!
