Well first deliver Gingerbread for OB before you make any further promises LG. Even my Samsung P1010 now have GB, seems like Samsung might be the way to go.
Scroll down to GPS Test
Check Use Extended Conf File (this will be for gps.conf in /data/gps which I will include with the Bionix 2 release)
Click System Settings
Check Use XTRAS
Click SUPL Setting
Click SLP Server Setting
Here, you can test for best results. I am using the Spirent server
Hit back x3
Click Get Position
Session Type> Single Fix
Oper Mode > MS-Based
Go outside in a clear view
Let it do its thing for 10-15…
You should be good to go.
Again, for SLP server, test each one out.
After a lot of fiddling, I’ve found a fairly easy way of fixing the GPS on this device. gps.conf has two lines of code which make a lock nearly impossible. Anyways, here’s the fix. Use root explorer to navigate to /etc and find “gps.conf”. Mount as r/w, and long press gps.conf. Select “Open in text editor”. Scroll down to
# For SUPL SUPPORT, set the following SUPL_HOST=lbs.geo.t-mobile.com SUPL_PORT=7275
Hit the back button, this will save the changes and create a backup of gps.conf which will be named gps.conf.bak . Restart the phone, and use the free GPS TEST app from the market to test the gps. You SHOULD be getting a lock within 5-10 seconds.
Enjoy your fixed gps!
That new supl server (supl.google.com) works great! Thanks for the tip.
