I am finally getting around to trying to get mobile data connection going on my Gemini. But I am having no luck. To say that I have been struggling would be an overstatement, since I simply have gotten nowhere at all...

What happens when I try to power on cellular in cmst is that I get an error message saying:
Error Name: org.freedesktop.DBus.Error.UnknownObject
Error Message: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist

So, ofono and/or connman has not registered stuff related to the cellular modem?
I really have no idea of where to go from here, and what to check for troubleshooting. I tried running ofonod in debug-log mode, and got a whole bunch of info...
When I just check the logs from ofono (with normal logging) I get:

And so on forever. What should I check to find out what is going on?

(Note, I did have to reflash my device completely once, but I believe that I got the NVRAM backup back into its correct place, see separate thread of mine)

I haven't had a chance to play with the modem under Linux yet. I'm too disturbed by the poor graphics performance at this point. But I did lose my baseband due to reformatting the flash, and the method I described to you in another thread for reformatting and reflashing (including NVRAM) in one fell swoop does not restore the GSM baseband firmware (under Android, baseband and IMEI numbers all show as unknown). In order to properly recover, I had to boot Android with a *BLANK* NVRAM partition, let Android restore the baseband firmware, then flash the NVRAM partition separately (which then restores the IMEI numbers). It's a two-step process. User "aleem" describes it here: https://www.oesf.org/forum/index.php?showtopic=35259. Looking at your log output, RIL (Radio Interface Layer; i.e., the interface to the modem) keeps disconnecting, which I saw in my Android logs as well.

Once you've double checked your NVRAM stuff (perhaps make a call in Android?), if ofonod still fails then also double check that you added the 'radio' user/group and rebooted etc.
As per: DebuggingMobile

Thanks both of you!

This means that I will have to reflash again, since I am currently running LinuxOnly :-)

I will get an Android partition running, and then report back!
DonOregano
Nope, cannot do anything "mobile" from Android either. It would appear that I have been struck by the problem described in here:

https://www.oesf.org/forum/index.php?showtopic=35233

Will attempt some of the solutions described in there...
