Master Ramy

is the O.P.

so any shout out, fist bumps, high 5's, hitting of the THANKS button- make sure to send them his way.​

im always going to remote areas with no service. its always really crappy when gps fails and i have to pull out the fishing, hunting, atv map out from behind the seat.

this isnt going to fix all my navigation issues, but it should help.

i hope many of you find this useful. i havent tried this yet but it suppose to work with all androids.​

[GUIDE] GPS without Data signal!! Works on tablets too!

credits to Coycane, he showed it to me, I'm just giving you the guide.

I use it on my Xoom with great results, so I can follow the car the whole way without needing internet as long as I open maps when on internet.

The way it works is simple; a Garmin GPS unit doesn't require internet to get you places, so why would your phones GPS? In reality, it doesnt.; the GPS hip can b programmed to communicate independently with the satellite, allowing you to be more Mobil without needing Internet!

But maps needs internet to start, so what I do is open maps, get my directions so they're on map, then I can turn off internet and the GPS lock will stay and follow me.

Its very simple; starts out the same way you'd do a prl hack;

1. Get your MSL number. Do this by getting an app from the market called terminal emulator. type in: su (hit enter) getprop ril.MSL (caps sensitive, then hit enter) your MSL will be there. It will be a 6 digit code. Write this down for later!

2. Install drivers for your device on your computer. Look up a Youtube tutorial on how to do this. It was the hardest part for me.

3. Download QPST. Link is below. On your computer, extract the QPST file, open it up, and double click on setup. Go through the installation process.

If you want to make a nandroid, tho it probably won't backup this section and I doubt ull have issues anyway, now would be the time to back up.

4. Go back to the phone and open up the dialer. Enter this: *#*#8778#*#*

5. On the menu that pops up there will be a section labeled "USB". Change it from PDA to "Modem"

6. Back to the computer. Hit the start menu and open up device manager. Double click on "ports" and you should see your device there. at the end it will look like this: (COM#). Write down the number at the end of the COM.

7. Hit the start and search for QPST and open it.

8. Now go to "start clients" and hit "SERVICE PROGRAMMING". It will ask what port you will be modifying, just click your device and hit ok.

9. there will be these tabs with CDMA, CDMA-2, ESN, etc. Click on the one that said "GPS or GpsOne". On the left check all boxes, usually phone has only 1 checked. REMEMBER what ur phone originally had checked in case you need to go back.

10. Finally, hit "write to phone". The phone should reboot, and you're done!

11. Once it boots up, go back to the dialer and enter the *#*#8778#*#* code again. Change it back from modem to PDA and you are done!

Make sense? And no, this hack is not dependent on any particular phone or tablet, should work on all androids; worked on my Xoom perfectly. Try it and best of luck!

Let me know if u have any questions or need any help. I've found it extremely useful on my wifi only Xoom because I can always know where I am without having to tether from phone first :-)

Enjoy,
