[GUIDE] GPS without Data signal!! Works on tablets too! - Nexus S 4G Android Development

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

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.

This worked great for me, my phone isn't even activated right now (I've just been using it on WiFi) but it GPS locked within only about a second or so; worked great!

Glad to hear its working out for you guys!! And thanks for the extra stuff, I'll throw into the guide asap on my way home from Disneyland right now so as soon as I can in the meantime, feel free to link others back to here as you see it working

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?
Sent from my Nexus S 4G using Xparent Red Tapatalk 2

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.
Sent from my Nexus S 4G using Tapatalk

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
https://www.dropbox.com/s/mthba0oaizzo6t0/samsung_driver.zip
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...

[Q] Wifi Tether setup

Hey every one, I rooted my phone last night and so far so good, Some gliches here and there, but thats to be expected.
What I am having problems with is setting up my WIFI Tether. I downloaded the WIFI Tether app from the market (the one with the green broadcast signal on the main screen) and I cant get it to give me access to the internet.
I am not new to "networks"... I have 2 laptops, a PS3, 2 desktops, 2 PSPs, a DS and a SONY TV - all hooked up to my secure wireless network at my house...
But this has me stumped...
I am getting limited access and no internet connection through my broser... what I am doing wrong??
I dunno what info you would need to help me, but my laptop is a Toshiba Satellite... does not have bluetooth, only wifi...
EVO is rooted with unrevoked, flashed amon ra recovery... any help would be appriciated

Download the apk, install via ADB
1st. Download apk wireless tether, latest update, make sure the first wireless tether u've installed is removed completely from Manage Applications settings.
2nd. Run ADB prompt by adb remount, adb install file_name.apk
3rd. Reboot
4th. Test it

Okay the one I down loaded from the market was the one called..."wireless tether for root" by Muller,Lemons, Buxton
So that particular one is no good?
Okay - the only issues I have with your post is the whole adb stuff...lol.... sorry, im still new to all this and Im not sure what that is... Can't i just download it and install it the regular way? just curious...and if *NOT* then can you explain adb? is it an app or some thing like that?

How did you get it to work? I just uninstalled it and was going to try and set up the other suggestion... the one he told me about looks just like the one I just uninstalled...
ADB is like a program by SDK Tools.
Hold Shift + Right click on the folder C:\Android-sdk-windows\tools
Open command prompt on that
Type 'adb devices' while your plugged in with the usb plug to your PC
If it shows a line below that like your device 'HTC#####...' Name.
Type 'adb remount', then put the file of the apk in the tools folder.
Type 'adb install file_name.apk'
and type 'adb reboot'
Your phone should reboot and have the wireless tether apk installed and working...HOPEFULLY
AND READ THE GUIDE FOR ADB ON BEGINNERS ITS USEFUL BY THE SEARCH BUTTON

Make sure you get command prompt on your pc using your phone in usb mode.
Make sure USB Debugging is toggled on!
yeah I will - thanks, ill post in a few hours how it all went...
This **** is really confusing...lol... I wish there were"user manuals" for all the apps out there...
I know it seems simple once you get the hang of it all, but in the beginning, it really makes me feel like an idiot...lol
easy method
download the app from the link in the post a few above this one with your phone
make sure you have a check on non market app install in settings, applications
drop down the notification bar and touch the apk that was downloaded
it should install
done

Thanks for the input ZJ, how ever - I have already "installed" it twice, Getting it to install is not the problem at all.
The problem is getting it to work correctly. Any help on how to get it to connect to my laptop with out limited connectivity?? It works, it connects to the laptop, but it keeps saying limited connectivity... I cant actually get on the internet - say thru a browser or what ever...
I don't really think I need to go through adb to get it to work, cause it actually installs and works fine, as far as broadcasting wifi and being found by my laptop.
My computer recognizes it and every thing...when I connect to it though - It just says "connected with limited connectivity"
any help on this would be great... maybe the configurations every one is useing to get it to work?
There are several setting and what not and I guess cause I dont have a "user manual" its gonna take me messing around with the config to ...um fig...ure it out :/
::Frustrated::
When mine does that I go into settings, wireless, mobile data settings, uncheck all but top and always on, set provider(system?) to automatic. open a browser and surf or google maps, just to get the connection going and data transfers started, then open a webpage on laptop and it usually works, after it connects that first time then every time it just works, that first hump of connection is tough

In my opinion, JayStation3, I think you would like wireless tether built already into the Froyo ROMs we have here from XDA developers, maybe that can save your time a bit. Just a thought.
You can flash a new rom with wireless tether and a new kernel to make your phone ready to use. Just a thought once again, can't help you much a bit because I already am using it and it works fine.
Ok, here is a stupid question... Do I have to have to have "wifi" in the phone setting turned on when I use the tether app? I just assumed that the tether app turned it on automatically... I guess I could try it real quick to answer my question...

okay, that must have been it. I turned on my WIFI in phone settings and... well its working now... I figured that it used data connection like 3G and 4G...but i do have wifi here at my house - So I guess Im still kind of confused... Cause essentially - if I have wifi turn on through my phone - its like my phone is just acting like an access point, which would be pointless if I was trying to use my phone as a hotspot in my car or on a plane or some thing... Ill try it again tomorrow at my office where there is no wifi and see what happens. In the mean time Im gonna continue reading as much as I can here on all this stuff...
I do wanna try flashing another ROM here soon, I just want to learn as much about all this as I can. Im still kind of confused about flashing and restoring and making sure I have all my back up done right and what not... I look forward to trying out some of the awesome ROMs I have read and seen on the forums... but I want to be able to go back to the froyo2.2 incase I dont find any thing I really like...

[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.

No it doesn't but I tried it anyway and found that no, it really doesn't. Thanks for trying though. I'm having a brainfart on typing letters into the dialer... how is that done again?

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?

Happy to help. I'm not sure exactly why it starts with WCDMA and then goes to unknown, haven't really looked into it too much.

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?

As I said in my first post, that breaks market.
Please read before posting, isn't that a forum rule?

I am using tapatalk app and it won't show me all my subscribed threads, but I'm pretty sure in general a guy made a thread about how he did it for an EVO he gave to his daughter or something, it listed what you needed to remove. Sorry I realize that's not too helpful, but I will check back here tomorrow and if you didn't find it, I'll post a link.

I found it, see if this works for you. The op says market works.
I did notice the guy had to use a sense rom.

i don't want to use a sense rom, but i'll give it a shot. i'll report back in a sec. thank you very much for the fast reply!
EDIT: after reading the thread, i kinda don't want to rock sense. that thread isn't applicable is it? i'll try forking around with my cm7.1.zip and see if i can get similar results.
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.
Just flash amon ra and r2r going green, its sense 3.0 very stable & clean. It's got a built in option to turn off radio

Two posts above completely missed the point.
A) IM NOT LOOKING FOR AIRPLANE MODE SETTING UNDER WIRELESS AND NETWORKS.
B) IM NOT USING SENSE. JUST NO.
c) what I am looking for is a configuration file, and if you've never edited grub or Apache etc, you'll never understand what I mean. I haven't tried the apk removal yet, but I will in a sec
Thanks for your help pointing to the apk removal thread, but I'm hoping for real developer suppot here

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!

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

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.​

below is a copy/paste from the link above (just trying to spread the love)​
[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,
~ Master Ramy

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.

Didn't work on Juggs 5.0 I don't get anything back from Terminal Emulator.

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.

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.
