[MOD] [GUIDE] GPS without Data signal! Works on tablets too! - T-Mobile Samsung Galaxy S II SGH-T989

I take no credit for this guide. i found it on the nexus s 4g dev section.
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!
QPST: http://www.x-drivers.com/catalog/fla...pst/12051.html
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,

Just a quick question, does this stick through rom changes or does this need to be applied every time a new rom is flashed? And thanks for bringing this here!

I read Nexus trd as Nexus Terd.
That is all.

If my phone is unlocked, I don't think we need MSL right? However, how did you get the *#*#8778#*#* to work? I tried it with cm9 but it wouldn't do anything. Thanks for the help.

I've lost data and not GPS before without doing this. Won't reroute tho. Portable GPS devices have maps loaded in them, that's why they don't need internet. You can download maps on your phone or pre cache maps of where you are going..

I am also having a problem getting the hidden menu to pop up. Since ICS it wont work. And I tried to go back to stock ICS and it still wont work. Does anyone have a fix for this?

doesnt google maps already do offline mode? and im pretty sure you can use gps with data off or else there wouldnt be a point in having offline maps, but im not 100% just a though

yeah google maps have an offline mode if you saved the map of whatever location you wanted beforehand. But, i'm not sure whats the purpose of this mod because GPS works without DATA already... so maybe its for preloaded maps? I got lost reading the OP and decided to breeze through the comments but that didn't really clear things up lol.

My GPS does not work without data...
Going to give this a try

Some other benefits of GPS working without DATA being on is using the phone as a golf gps. Battery drains pretty quick over the 4-5 hour period and not having DATA on could save a lot of battery. I tried using a golf app without data and it didn't work or maybe it was just the app.

I am unable to get the MSL # on both my TouchPad and GS2, I know others are having this problem as well. Has anyone found the reason and a solution? Thanks in advance.

[Q] Is there a FREE way to turn off radio only?

I want to be able to turn off the Radio only so that when I'm Wire-Tethered to my PC and playing a game I don't get any calls or texts to slow down my connection or be disturbed.
I found a thread in general where someone advised using tasker but it's $6 and I just want to be able to disable radio only. Airplane mode kills everything.
Thanks in advance for any advice.
There has to be a way...
There might be a way to do it via dial pad commands. I know that I was able to do this on a Droid in the past. I'm looking into, but make no promises.
edit:
Ok, this is what I've come up with.
*#INFO*1111# - Testing mode
Go into Phone Info...
Scroll down to Set preferred network type:
CDMA only
This should make it so the only cellular connection would be a data connection.
For my phone WCDMA Preferred is the default, which should be what you want to go back to to allow phone calls again.
Let me know if that works for you?
There's an app I used when I was on Eclair called Widgetsoid. It was the ability to toggle pretty much anything u can think of on your phone. I havent installed it since upgrading to Froyo so I can't verify that it can do what you need but its free and probably worth the download in any case. Check it out and let me know.

Just goto the phone dialer and type in those exact *,# and numbers (info is 4636)
once you put in the last # it will take you to the "testing" menu.
Let me know how it goes.
OK, I see it... will let you know how it works... Also, aren't our phones supposed to be set to CDMA? It had unknown and now it shows WCDMA. Isn't this the cause of the TWS bug?

It is the cause of the TWS bug. Our phones are constantly searching for a gsm signal never to be found. Causing battery drain. It has to do with the Galaxy S i9000 being gsm and samsungs poor ability to make changes to the coding.
Sent from my always stock, froyo Epic
This actually assisted in correcting or at least varifying another problem's solution. I've seen forum discussions point to PRL updates solving the TWS issue but other say it doesn't. However I installed sprintzone and let it install the PRL for my area. In doing so it set the default radio search shown using steve's info trick shown above. And no more TWS after reboots.
Woohoo!

[Q] disabling cell radio?

I want to intentionally disable the phone from making any phone calls. I'm running cm7.1 on my evo and I want it to be like a dedicated mp3 player with android market access.
I don't want to use airplane mode; I'm looking for a more permanent solution that can't be easily toggled.
I tried freezing com.android.phone and the dialer storage with titanium backup, but then market compatibility broke. Market returned server error.
Possible fixes (that I've thought of) :
Disabling radio driver?
Tricking market to not depend on phone?
Some phone or cm setting I'm missing?
Permanent airplane mode that still doesn't bug out wifi?
I know on cm builds of tablets (nook color and gtab) know that its a tablet and not a phone, and doesn't come with a phone option. Short of compiling my own build of cm7 (which if it's easy enough ill do), is there a way to trick cm7 into thinking it's a tablet?
I don't want to use airplane mode; I'm looking for a more permanent solution that can't be easily toggled.

Airplane mode is the only way. Once you turn it on, it's really not easy to turn it back off, you have to go to settings-wireless and networks.

Is there a way to set it and remove the option?
I know on Ubuntu Linux, specifically grub bootloader, and each of the options were available to edit on a conf file. I edited mine on my computer and added and deleted lines on mine. Does the android setting rely on a similar conf file?

FFS, if you're the one that's gonna be using it, then just don't make calls. You can always toggle Airplane mode off, btw, to use the market.

Goodluck finding dev help. They are few and far between for the EVO anymore. I suggest downloading the Android sdk, finding some threads on here and other forums and learning it yourself. Biting the hand that feeds isn't going to help.
Boo
solved. Procedure:
1 Flash cm7 and gapps.
2 Let all the gapps install and update in the background.
3 Install titanium backup from newest updated market.
4 Make backup of dialer and dialer storage (com.android.phone and com.android.telephony)
5 Uninstall phone, and battery pull when it force close loops
6 Uninstall dialer storage after the reboot finishes
7 Wifi should still work the market!

Possible ICS ROM GPS workaround

I was able to gain GPS lock in an ICS ROM without flashing a GB ROM. I performed this on Calk's E4GT2 1.2 ROM with FC22 Modem (FC18 kernal). I did a fresh install and confirmed that I was unable to get GPS lock in Google Maps and Nav.
I was able to achieve lock 100% of the time within 30 seconds after using this procedure. I got this idea from the way people have been tricking thier GPS to work: with a GB flash. I figured that here must be a GPS cache or buffer that is holding data - but I am no expert.
You will need these apps: GPS Status (market), FasterFix (forums or market), and TeleNav GPS (backup from Sprint ROM or maybe market (IDK)).
At each step of this procedure, see if you are getting lock in Maps/Nav. If so, good for you. If not keep following the procedure.
1) First, see if you are getting lock in Google Maps/Nav (duh).
2) Install the apps.
3) Trick #1: Use FasterFix to set the North American Server (try for lock).
4) Trick#2: Load GPS Status go to Menu>Tools>Manage A-GPS state. There are two options. "Reset" is likely not useful. "Download" installs helper data into your GPS cache. Use this Download feature. (try for lock).
5) Trick#3 Load TeleNav GPS. Input an address and start navigation. The status bar at the bottom should say "WEAK GPS." This will go away eventually as TeleNav GPS achieves lock.
6) Trick #4 At this point, I was able to get lock in Google Maps/Nav right away. Later, I wasn't able to get lock. I did the procedure above and let Google Navigation continually stay locked for 5 minutes or more (to get data in the GPS cache) and moved around (just around my building). After this I was able to get lock 100% of the time in different locations, all several miles apart.
I am guessing that this works because TeleNav GPS is a better GPS program than Google Nav and uses the GPS radios more effectively. You should be able to use TeleNav GPS for Trick #4, too (getting data into the GPS cache).
Of course, the advantage to this method is that you don't have to flash any ROMS. Less flashing means less likelihood of getting a bricked phone. The disadvantage is that it takes a bit of time.
I look forward to seeing if anyone else can get this method to work. I also look forward to any comments on the technical aspects of this.
Interesting. I've always just made sure I got a lock before flashing ICS.works every time lol.

This didn't work for me. Hopefully this is successful for enough people that some community wide fine tuning happens
Actually I tried using GPS status before and it never worked but I got an instant lock after using faster fix. This is the first time I've had GPS in weeks thanks.

I flashed a GPS fix zip a few Weeks ago that I found on the blazer ROM thread that worked nicely. (not just for blazer tho, just saw the link mentioned there) It just adds a file onto your system folder or something. Too lazy to search on my phone, but that might be another option if this doesn't work.

if you have gps lock on a GB rom and then flash over to ICS it seems to solve the issues people were having getting/keeping lock on ICS, its an older solution from the ICS leaks but it works, for whatever reason...

Great write up, thank you very much! Looking forward to trying this out on a 1800 mile road trip soon - don't have to drain battery the entire time just to see how much farther to the next turn
A few suggestions that might help make the guide clearer:
2. If reinstalling drivers on your computer, be sure to remove the old ones! (while I could ADB into my device with no issue, when I switched over to modem from PDA, the computer didn't recognize the device, requiring me to reinstall drivers - probably conflicts from multiple android device drivers being installed)
7a. I had to add a new port in the QPST configuration interface before it saw my phone (ports, "add new port", "COM14" for port, "android" for label).
9. I had to click, "Read from phone", while in the GPSone tab, before it allowed me to modify any settings.
Again, these are all relatively obvious things, but extra clarity helps those of us who are a little slower
Thanks again - and GPS locked on within about 20 seconds. It does seem to be a little slower than normal, but that could make sense with all the extra options we're requiring of it.

Thank you ramy, just some concerns before I do this, does this effect my contract in any way (cost wise), will I still be able to get signal as normal?

That is a cool trick. However, you could do something a lot easier and not hacking anything.
Download Google Maps, enable the Lab "Pre-Cache Map". Pre-Cache the part of the map that you will be traveling and then you are good to go.
The Wifi receiver works as the GPS and for both my galaxy nexus 4g and asus tf300 has worked perfectly. Turn2turn navigation is amazing.
I am not sure if anyone else has tried this but for me its been a success.
However, I still have to admit your trick is amazing. I will try it when the Pre-cache method fails me.
This is pretty cool, locked uber fast and it's uber accurate now (verified by using maps and turning on satellite view) but.. I have to reboot to turn my gps off now? I can't get it to turn completely off without rebooting now.. Anyone else getting this?

It should have absolutely no effect on your contract since it utilizes the GPS chip in ur phone hardware to connect to the satellite, no sprint or any other middle man. I've used it on my phone for months with no issues, and I have it on my wifi only Xoom and works perfectly, and its not even on a contract, so that should be fine
I'll have to try the pre map cache thing, thanks for the tip! The thing is GPS is more accurate than eifi receiver, and searching for eifi sometimes takes more battery, so if found GPS to be more trustworthy, but that could just be me...I'll try it tho
I turn GPS on and off all the time with no issues. Might be ur agps data, so try clearing those and maybe wiping ur usual cache partition and see If it helps..mine never had an issue with turning it on and off..
Let me know if u have any other questions! Glad you all like it!

I have one other question, say you do this hack for GPS with no service and your phone gets stolen, is there a way to track it with the GPS even when not in service?

I'd think that as long as the thief connects it to WiFi, then yes. I use AndroidLost for my phones, and it'll send commands over WiFi so if that's connected then you should be able to GPS it or do the other neato features provided.

I'm confused..On my old Hero im 99% sure GPS lock worked without data (obviously couldn't get directions unless I had data for a min)
And the same goes with this phone. If data/4g is turned off and I open maps, I still get a lock almost instantly. GPS works while in airplane mode too for those who didn't know (along with WiFi).
Again, the only thing you'd initially need a data connection for is getting directions - at least with google maps.

Followed the instructions and everything went according to the write-up as far as the steps. Unfortunately I still need to have my cell radio on to acquire a gps signal
these are the QPST drivers, pulled from the 'HOW-TO flash to MetroPCS' thread

ok so this is weird.
I wrote the changes to the phone.
it rebooted. I opened my gps test app in airplane mode and everything worked. I disabled MODEM and checked PDA and checked the gps app again. all the sat's were gone...

Gps issue..

I have an issue with google maps since the past few updates at this point im not sure if its the app itself or my phone I tried other maps app and result were the same...
When I turn my gps on and on google maps press my location it just never locate and when scrolling my status bar down I can see it says searching for gps... and it keeps on going
Also when I need to go somewhere it's just super confusing the navigation app tells me the first directions and just stop working as in no more voice directions after the first one and im always in the same place in the map no...
I really need my gps if someone could help me out...

Can you try GPS Test ? That will rule out the GPS signal works fine. If that fails then you need to fix gps lock. Follow this thread here.
Once that all is sorted out, Try Mapquest's app till you sort out Google Maps. Get Faster Fix. let it set to the geographical continent of your location. That's a one time task. You can forget about it afterwards.
I still have the same problem and did a lot of experimentation. You need to enable location access in 3 different places if its not already on.
1. Go to "Google Settings" app. Make sure location access is turned on for apps.
2. Under phone's Location settings, allow location access. That will turn on GPS and Wireless position. Of these turn off Wireless part by unchecking that one alone.
3. I am not sure of this one, but you also need to check Google maps settings to see if its allowed that all pervasive location access. Don't let it save history though.
Try that and re-post your progress.
Thanks alot guys for the replies sorry for late answer so I decided to try the nvrebuild thingy I still didn't get a chance to use my gps to go somewhere but on a sidenote now when I press my location it can finally locate me !
Also during the reboot is there supposed to have a little blue words saying nvrebuild? Because I didn't get that and when I have done an nvbackup before I did have it just want to make sure

It's been a while but I don't think it will show that text. I think it's because this a function provided either through the modem, or one of the factory test type apps. I'm pretty sure the reboot nvbackup command is a function of a different partition altogether, but uses recovery to execute.
I could be waaaaay wrong on this one as it's just a guess based on my experiences with both. But even if I am wrong, I still am quite sure there's no blue recovery type text when you do this.
