Praise God; it works.

Flashed the CM12 ROM, the google apps, and the zv5 radio, boot up, flashed the boost APN fix, and my signal shows as boost and my GPS locked on in under 10 seconds.

I used the Feb 25 release of the lollipop ROM, the most recent ones seem to cause problems on my device.

Following is my exact GPS.conf file:

XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra2.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra2.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra2.bin

Something maybe worth trying, or maybe it's just a coincidence. I've had lousy GPS with the Volt ever since I got my first one three or four months ago. Often loses connection. Often reports that I'm zigzagging across streets, through yards and buildings when I run. Never gets a lock indoors, though all previous phones I've had did (all fairly cheap ones, too, like the Optimus V and Samsung Reverb).

After trying everything here, and every GPS "fix" app I could find, today I tried the old fix for the Samsung S3 - turn it off, open the case and remove the battery, etc. Use a tiny tiny phillips screwdriver to tighten every little screw. Most were pretty tight already, none turned more than about 1/8 of the way. Put it back together and I've actually had a reasonably strong signal indoors throughout the day, and did a quick run outside that for once seemed to track correctly. I'll have time for a longer test tomorrow, but I thought I'd throw this out there if anyone else is still having intermittent trouble with theirs, maybe it's something to try.

If i just want to have my gps work better and be more accurate, do i just use the O.P.?
And if that is the case, do i add in the lines? Or are they already included in the config file and i just have to edit them?

I've had the best results with the last conf that I posted (post #100)...

Of course, results may vary depending on your location, by for me it's usually accurate within 50ft. Just copy the stuff between the code tags and replace the contents of your conf file. Make a backup first, just in case. If you're using Root Explorer, it will do it automatically when you save.

I found some copper soldering wick. It works way better than just regular aluminum foil. I'm getting some SNR signals close to 40 now....Go with copper tape, copper soldering wick, or copper wire if you can. See the SNR (signal to noise) ratio of each signal needs to be at least upper twenties to low thirties to get a fix and you need at least 3 satellite connections to keep a fix. The stock gps reciever in the Volt just isn't strong enough.
