Today, AGPS Patch has reached a total number of 28 officially supported devices. Support was added for the Asus Transformer TF101, Samsung's Galaxy Nexus, Samsung's Galaxy S I9000, and HTC's One X.

I predicted that companies would get wiser and start providing properly built stock ROM's for GPS usage. That was incorrect. I'm willing to research and work with people to bring more devices into the fold.

There have been millions of downloads of my personal xtra.bin data and tens of millions of queries submitted through the DNS pool I maintain for Stratum II time servers. I lost track of the number of ROM's that have incorporated this patch. In fact, v3.x began 11 months ago and has brought worldwide help to the masses.

And remember, I don't have to release new versions of this patch locally because it has been so fine-tuned. But, I'm always working on the xtra.bin data almanac and the Stratum II time servers to keep this thing going strong.

To the few that have donated to support the many, thank you very much.

If anyone would like to continue to support this project

for growth in more devices and continual data provisioning, please consider donating as well.

Hi all.

I've been using this patch for a while, with superb results. Lately on a regular journey route I've noted some interesting behaviour.

There's a GPS blackspot near me, probably only a few hundred yard long, I've tested this with several devices and different apps on those devices. That's not the interesting part....GPS gets a lock normally in 10 seconds or so for me, but after this blackout it won't connect again for several miles. If however I open up GPS settings by tapping the searching for GPS notification, change nothing, and back button to the app it connects immediately.

Any idea why its not sorting itself out, as fast as it does when it starts up initially?

I'm using codefirex 4.2.1 BR2, had the same behavior on 4.1.2 and agps patch 3.1 nossl.

Cheers.

[HTC Inspire 4G] crypted:
That's definitely a strange happenstance. Can you confirm that this is a problem when running various apps? Like, it doesn't relock with GPS Status, Google Maps, another Maps program, etc.? Let's rule out app library issues to know it's general since it clears itself as you describe.

If that doesn't work, make sure it isn't the ROM by doing a Nandroid and flashing something like stock deoxed.

If the two above are not good, it could be that it gets a bad reading in that area which throws its temporary "in-use" cache for a loop if you will.

Lastly, hardware could slowly be failing... My wife's Inspire 4G bit the dust a few months ago. Its death was crazy slow and weird. Slowly growing amount of random glitches until it just quit powering up.
[HTC Inspire 4G] andyverran:
Hi, thanks for your reply.

I've tried it with 3 apps, two for measuring speed, which also count satellites and with navfree. I have not tried it with GPS status or GPS fix, but I will!

Test devices for the GPS hole were HTC desire s and samsung gt-p1000. They all fail in the hole but recover sooner than the dhd, neither are patched.

I will retest tomorrow with the same app on two devices on the same journey.

I'd previously tried Blackout ICS as well as the two versions of codefirex, I don't think I had agps patched when I had cm7.2 on there....its hard to compare with the original as gps was soooo bad, but on the rare occasion it worked, when it then lost signal it would be and hour before it got a lock again....

As I guess you know the GPS on the DHD was always appalling, so much better even with the issue after the patch.

Cheers.

Andy.
[HTC Inspire 4G] andyverran:
Right, test conducted.

Devices used:

DHD running codefire br2 android 4.2.1 with the GPS patch.

Desire S running pacman (lots of cm10 etc in that i think) but not GPS patch.

Software:

Both devices using GPS status.

The desire s didn't loose GPS signal at any point, but did drop to 3 satellites locked.

DHD lost signal and did not regain a lock for 4 miles.
[HTC Inspire 4G] crypted:
First I'd like to point out this discussion is on the Inspire4G and not DHD thread. I didn't fully understand your device lineup above.

I would consider checking and soldering your antenna springs as discussed through the link in the Notes Section, though.

Also, consider taking your information and posting on the right thread in the DHD forum in case someone with that similar device has any suggestions. Make sure to note that this is a continued discussion where you accidentally posted on Inspire 4G.
[HTC Inspire 4G] andyverran:
Oops, sorry my mistake....did register the device difference!

Will try and find the right thread.
[HTC Inspire 4G] kraze1994:
Used this patch and was getting 7 satellites within a matter of seconds and a full lock in under 5, unfortunately since I flashed to the Sabsa Prime I can't get a lock at all. I'll get 11 satellites in view but wont be able to lock any of them.

Is there a specific one designed for North America only, noticed there were a couple on the main page but they seem to be older versions.
[HTC Inspire 4G] crypted:
There's no reason to do continents. Someone was being silly with that idea.

If it worked before, and a ROM change made GPS stop working, your problem is not here my friend.
[HTC Inspire 4G] kraze1994:
I rebooted the phone a couple of times and let it sit open and now it's working great, 10 satellites locked in a few seconds. Not sure what happened but it's working great now!
[HTC Inspire 4G] crypted:
It's caché clearing most likely as my Notes discuss.
[HTC Inspire 4G] crypted:
TopNTP - the app.

We need bèta testers. Hopefully we can get some useful feedback to optimize this app. The patch itself has been proven to work, we just need to know for as much as possible devices if we can a) really install the patch and b) if the app is sort of clear in its use.

Get it on Google Play!
[HTC Inspire 4G] kraze1994:
I'll install it and report back.

Edit: It is actually incompatible with my phone according to Google play(HTC inspire).

How does this compare to FasterFix? are they redundant? Is this app doing the same thing as the original zip download?

This app does what FasterFix does, plus a lot more. It also does the same as the original zips, if you want. You are more flexible with the app, instalation is easier.

samsung galaxy s plus i9001

This works great, however I recently lost GPS for no reason. Couldnt get lock.

I tried adding these settings to build prop and after i got a lock for first time in ages

ro.ril.def.agps.mode=0

ro.ril.def.agps.feature=1

Dont ask me why, or how these work but its the first time i had a lock for ages.

It is amazing

Thank you!

[HTC Inspire 4G] crypted:
Glad y'all think so! Some of the users on the DHD thread get a little cranky. Not like I'm selling the dang thing!!!

Anyway, I'm glad I can help others with this. I'll keep toying around with it. Some of the Europeans gave me some insight that there must be some serious issues in some areas with signal and connectivity.

I find it ironic and a bit humorous that there are users in the same country or region that have great performance and others say it's useless.
[HTC Inspire 4G] harpo1:
I'm in the Northern California area. I tested it outside my house with a clear view of the sky. I have an otterbox defender case on it. Compared to Angel Death I get quicker locks but less satellites and not quite as good error rate as AD.
[HTC Inspire 4G] crypted:
Interesting. The differences shouldn't result in that all too much compared to AD's which was my basic starting point. Hmmmmm!

I have a few theories and ideas for perfecting this thing. But generally, it's a good solution for many who haven't had the best of luck.
[HTC Inspire 4G] harpo1:
I agree it's a great solution. I change ROMs quite often so I'll continue testing when I change and see if the results are different.
[HTC Inspire 4G] RampageRR:
Using VU 2.35, I saw a definite improvement. Went from approx 30-45 sec to get a lock, down to about 6 seconds. Thanks!

[HTC Inspire 4G] crypted:
Glad y'all like it!

I'm already working on v1.2. I've got 4 test builds ready to go. This will direct me further on my quest for great GPS-work.

I anticipate the next version in a week. I won't rush it unless I see a reason to!!!
[HTC Inspire 4G] bdpyo:
Although this didn't work 100% for me I thought I would share my results.

ROM; RCMix Bliss v1.3

Kernal; ROM default

Baseband; 12.54.60.25U_26.09.04.11_M2

RIL; Default

Location; Philadelphia, PA

APN "tweak" configured.

Ok so I haven't had the best of luck with my GPS, ever so I gave this a try, preformed installation as required. After flashing, I found that it found "my location rather quickly. It showed me at almost 1 mile from my exact location.

I tried this from inside my 1st floor apartment and then once again outside in the open with the same exact results. I then actually tried to see if GPS were working for a set destination. Like I previously said, I've always had a problem with GPS on my phone and it would not "lock" and just kept saying "searching for GPS signal".

I'm not surprised, I just think it's an issue with this phone and not the actual fix. Either way, I just wanted to share my results. Thank you for all the hard work that was put in to this.

Note; I also tired this with and without the phone case for interference issues, also.
[HTC Inspire 4G] P00t:
Im not getting locked within 1-20seconds or rather not at all. I flashed the north America version.

Rom. Arhd 6.1.0
[HTC Inspire 4G] crypted:
DHD and some Inspire 4G's have an internal hardware issue with the GPS unit. Apparently, there are two springs that touch a plate on the back of the phone. Those springs may not be making full contact for those phones.

So, that could be your hardware problem since this has been a recurring theme of unsuccessful attempts at all sort of stuff as you've said.
[HTC Inspire 4G] crypted:
Did you follow the instructions and read the NOTES section?

Are you in a concrete building and testing? What are your physical surroundings like?

Does GPS work on your phone normally?

Have you done an initial "learning" period for the aGPS?
[HTC Inspire 4G] P00t:
I tested the GPS in empty surroudning, the high way.

When I was on miui, GPS worked normally. First time testing on arhd.

Initial learning??
[HTC Inspire 4G] crypted:
A device with aGPS requires time to learn information about the satellites in your viewable area. This is done while you have the GPS unit enabled and active. I use GPS Status for this.

Typically, I let that app operate for about 3 minutes. Then, I restart the app. It has a Tools section to "reset" the aGPS unit and to "download" aGPS data. You could reset it, then download the data, let it run for a minute, and then restart it if you're feeling frisky.

Where are you located?
[HTC Inspire 4G] bdpyo:
After a ton of research and a few different configurations, I've narrowed it down to that most likely being the issue, I even went tl a warranty store to ask for replacement and the guy just gave me some sort of inside line to HTC's tech support and I never followed through with it. So I went and bought a Nexus S to solve the issue. :)
[HTC Inspire 4G] bdpyo:
Also I don't have the courage to rip the phone apart myself.
[HTC Inspire 4G] Bzow:
Great work. Thank you very much.
[HTC Inspire 4G] P00t:
in the middle of the GPS status app, the loading icon just spins forever...

I reseted the AGPS thing then redownloaded it.

I am located in the eastern part of the U.S, Virginia.
[HTC Inspire 4G] crypted:
For the sake of asking, did you Mount the /system/ before flashing? Have you rebooted at least once? Some users said they had to reboot once or twice for it to work.

Lastly, that loading icon only lasts for a short time for me. Do you have a case on the phone by chance? If so, take it off just for fun.

Are you inside or outside?

If this is still an issue, I can give you the beta which is damn near the final for 1.2. You may be one of the few that have a glitch with a particular variable.
[HTC Inspire 4G] crypted:
Glad you like it. I'll have v1.2 ready in the near future.
[HTC Inspire 4G] suprtrukr425:
Thank you for this. I am running CM 7.1 RC, and this made a whole world of difference. Before I could hardly get a lock. Right after flashing this, I got a lock almost instantly.
[HTC Inspire 4G] :
Didn't work for me :(. But to be fair, my phone has never been able to get a lock \, even after a few minutes. So no difference here.
[HTC Inspire 4G] crypted:
Again, some devices have problems that software just can't overcome. But let's not get too down just yet. I just sent you a privmsg with two test builds. Try it and report back.

[HTC Inspire 4G] bigdog533:
when i was in recovery it said there was no files in the patch. is it something im doing wrong and if so what?
[HTC Inspire 4G] crypted:
Did you follow the steps? And, is the ZIP on your sd-card?

In Recovery, you first have to mount /system/. Then, you install the ZIP from the sd-card. Select the ZIP and then do the YES to install. ;)

If the patch isn't working when you do those steps, you probably didn't download it all of the way. Delete the file and re-download it. Sometimes it's easier to just transfer it from your PC via USB cable.
[HTC Inspire 4G] bigdog533:
Ill re-download and try it again thanks for the quick reply

Man you freaking rock!!! It takes less than five seconds to get a lock good looking out on this patch.

Another testimonial.

I am running the latest CM7 nightly and with this patch it really does get GPS lock much quicker.

Thanks a bunch
[HTC Inspire 4G] crypted:
Good!!! That was my only ambition. Just wait until the v1.2. I have it finalized, but I'm waiting on a couple more testers to respond with their results.

I'm kinda thinking ahead to v1.3 already, too. I want to give people who haven't had luck with GPS the best run for their money...wait I don't get paid! :eek:
[HTC Inspire 4G] ajdrausal:
What is the Change log for 1.2?
[HTC Inspire 4G] crypted:
I really don't keep track...just kidding. Man, that would make this pointless.

There will be five changes (4 new variables, 1 tweak) in the North America version and six changes in the Worldwide version (4 new variables, 1 tweak, 1 removal). I'm ignoring new NTP server pools from my count because those are just extra backups.

I'm still having problems with my GPS, can't get a single lock.

I've tried different ROMs, kernels, radios and RIL's. I've used this patch with different combinations of all of these and still no lock.

This seems to be new, I can remember it locking on last week. But now, outside in the sun, case off, this patch flashed, still nothing.

So I'm guessing it's hardware and I'm S.O.L., thanks for the work on this patch anyhow.
[HTC Inspire 4G] crypted:
Use a full wipe script and flash a ROM with known gps support. I'd use arhd or unity. Try the patch again.
[HTC Inspire 4G] bigt305:
Well each time I flash a ROM, I wipe Davlik, format System, Data, then Cache. Then wipe all user data/factory reset. I'm using RCMix (obviously), and the GPS was working fine before. I tried the new Android Revolution and no GPS lock either, so I'm fairly sure it isn't the ROMs.

Haven't tried a wipe script however.
[HTC Inspire 4G] crypted:
Try the full wipe that I use: http://dl.dropbox.com/u/15057375/mero01-xda/Wipe/FULL-WIPE-1.3.zip

Just so we're clear for other reading the thread, your GPS stopped functioning prior to trying this patch. You tried it as an attempt to get your GPS operational once again...

If you're somewhat brave and the phone's out of warranty, check out my second post on the thread. There are known hardware issues on some DHD and Inspire 4G phones. If you have some sturdy hands, that fix worked for someone else with a hardware problem who tried my patch before determining it to be so.
[HTC Inspire 4G] bigt305:
Yep I'm one step ahead of you. That was the culprit, some dust on the contacts. Thanks for the assistance, and for posting that vid.
[HTC Inspire 4G] thoffland:
I'll just add that I've been using this patch for a couple days and it's been great for quick gps locks! Thank you.

[HTC Inspire 4G] crypted:
Glad to hear it's been beneficial for you two. I'll get v1.2 up later today if I feel everyone deserves it!!!!!! Just kidding, it's on my list and should be done by 8pm CDT.
[HTC Inspire 4G] crypted:
v1.2 is here!

Finally! Version 1.2 has arrived for your GPS-seeking pleasure. There were a few changes to the GPS configuration. I added a few variables and tweaked one.

Also, the alternate "world" version has a variable removed. The removed variable caused false GPS readings on older DHD devices. Any Inspire 4G or DesireHD user can use any of the three versions available for download as a v1.2 release.

I have some ideas for the next version and will get started on it in the next few days after I read feedback from this release.

Don't forget to click the "Thanks" button, to rate the thread with 5 stars, and to send a Paypal donation if you're feeling all gitty from GPS satisfaction. :D
[HTC Inspire 4G] RampageRR:
What do you recommend for people in the US? The US specific one or worldwide? Does it matter?
[HTC Inspire 4G] crypted:
Personally I use the worldwide version. It's just a difference in ntp pools. Should be the exact same plus or minus meaningless nano seconds.

The idea of different versions stemmed from two things when people were making GPS patches.

1. Devices don't work well with some variables especially if it's an older device, so easy to remove if based on certain regions.

2. There is a thought that timing is everything. So, for fear of a few seconds lost from NTP servers, people started using regional NTP servers. That should be a non-starter even on slower Edge networks.

---------- Post added at 07:11 PM ---------- Previous post was at 06:52 PM ----------

All, if you downloaded before 7:07pm CDT, redo the worldwide patches if you're having an issue. The alternate patch was served for both versions. Sorry. I have it fixed on the server.

Sent from A Van Down By The River!
[HTC Inspire 4G] crypted:
I wonder if it's kind of a pseudo speed boost. In all reality, they should be the same. What could happen is you were kicked a problematic NTP server via its response the first time the NTP pool served you a server IP. And the second time, you were served a different IP which was responding to NTP requests normally.

Several planned enhancements for v1.3. I'm making a roadmap for up to v1.5. The reason I don't do it all at once is because I would like to do chunks at a time and ensure we all keep stability and performance. If I did all of my plans at once, it could prove a hellacious time to diagnose problems that particular users might hve.
