Can't win 'em all. But, that indicates the patch wasn't bad. Rather, it's indicative of your internal clock being out of whack with some data transfer issues.
[Acer Iconia A500] Cactus42:
I didn't know that, makes perfect sense since I've been relying on the clock updating itself while travelling from the UK to Sweden, which it wasn't.

Edit -

I'm back home in the UK now, had a chance to play around. Now on Thor's latest ROM but with this patch it now takes a maximum of 30 seconds to lock, currently watching 5 out of 9 locked in GPS Status so big thankyou - now I just have to pluck up the courage to root my brand new Galaxy S 2 to fix the GPS on that :)
[Acer Iconia A500] jjdevega:
Wow! Thank you! This worked great on my Galaxy Tab 10.1 Wifi:D I used the Gps.config and immidiately locked on to 10 sats!
[Acer Iconia A500] crypted:
Good to know! I'd be willing to support that device if others would confirm that it works on it as well.
[Acer Iconia A500] rredlin:
Still not 100% for me.....

After a fresh boot this works fine, but after closing ether or any of the apps that use GPS and reopening, the GPS does not launch, and nothing that uses GPS will find my location.

Very puzzled as to what could be causing this.....
[Acer Iconia A500] crypted:
Really sounds like a ghost process. Is it plugged in or in a case?
[Acer Iconia A500] rredlin:
i have an all leather case, but have tried it with and with out. also plugged and unplugged.

I know that the compass is affected by metal, but don't see how that would prevent the GPS from turning on after I have successfully used it with G-MAPs then closed it, only to find it wont reopen until I reboot the TAB.
[Acer Iconia A500] crypted:
I'm really at a loss. And you have tried v1.3? What about the "alternate" builds?
[Acer Iconia A500] rredlin:
I will try 1.3 and report back later to night.
[Acer Iconia A500] crypted:
I know it's a pain, but I'm definitely curious if 1.3 and/or 1.3N (alternate) will fix it.

If it ends up being the alternate that works, I'd be shocked as that suggests the GPS unit inside the phone is a bit older and cannot support an intermediate positioning variable.
[Acer Iconia A500] rredlin:
ok well, i tried the 1.3n worldwide... after reboot it did lock, just took a lot longer. nav worked and google location worked, how ever after closing these apps, and then trying to reopen them the GPS would not launch nor lock or find me....

I put the 2.2 ATT one back for now.
[Acer Iconia A500] crypted:
If you're overly bored, flash an alternate version like "GPS.CONF only (alternate)" so that it disables that one pesky variable for some GPS units.
[Acer Iconia A500] rredlin:
well I've been racking my brain (very easy task) to figure this out, while using your 2.2 patch and GPS status or GPS test it works every time, and even after closing the apps they still work.

I also have locus maps, which also worked after many opens and closes, but after using google nav then closing it, nothing will launch the GPS... so right now i have uninstalled it with titanium back up and I will re install it new from the market, and continue testing...

Thanks for your helping me with this.

Ok so even with the new g-maps installed, its doing the same thing, I can open, use and close any app that uses GPS IE: latitude,gps statues, gps test, locus, but after I use google nav, then close it, nothing will launch the GPS until I reboot. Thats kinda wacked, I use the nav part of g-maps on my phone 4-5 times daily (i drive for my job) and wanted the TAB to replace that, due to the larger screen!

Last edit for tonight.... it seems that when I use the arrow at the bottom left of the tab, to exit g-nav it locks up the gps, but when I use the menu icon and select exit navacation, it still works! So my troubles are not with gps at all its the way this tab closes the app.
[Acer Iconia A500] crypted:
NEW VERSION(S) OUT!

v2.2 is updated. There were bad ZIP links for which I apologize for. Further, I added some new BUILDS. These builds can work on all phones no matter what your manufacturer is. However, some manufacturers provide SUPL data for their hardware. I'm helping you take advantage of multiple SUPL SERVER providers.

v3.0 is here! What does this mean for you?

I provide you with my very own xtra.bin file. This has led to some beta-testers having INSTANT locks. I can't promise that, but it works wonderfully for all testers except one person in China.

Guess what!

It costs me money to provide this.

Donations would be welcome to cover hosting fees should this work for you.

What's next for the 3.x trunk?

You should see v3.1 in a matters of weeks depending on reported success of v3.0. I intend to create my own NTP servers and NTP pools. This may cost a few dollars a month, but should be worth it for all of us.

Other flashing recoveries may be supported. Right now, I'm only providing for Clockwork Recovery. But, there are two other easy installation methods available aside from CWR in Method #3.

I've added more notes. Read them if you have issues before posting.

I've added more information to Method 2 installations.

Finally, click thanks on this POST if you truly enjoy and appreciate the work! ;)

So which patch works the best for a500?
[Acer Iconia A500] crypted:
It's all about preference, but I'm big on the Google Build for all devices.
[Acer Iconia A500] dongimin2:
TIL Optimus One is supported. Thanks!

Userbars - lol
[Acer Iconia A500] crypted:
I just added a new flashable ZIP to both current versions. Some users are reporting issues flashing with CWM on the X8.

Thanks eagleeyetom for your help as always!

I placed this update on all threads so others who may not have had flash success can try it out. Feel free to send me a private message with what recovery app and version you're using, the phone model involved, and whether flashing anything worked.

Method 1 seems to be the best bet for anyone without flashable abilities with these ZIPs. It's a quick adb push script...

v3.1 is still in the works I promise. As stated previously, it'll be a bit longer before I get it out to the public. I hope to have my beta testing community trying it out in a week or so.

Again, v3.0 has all gps.conf variables grouped into sections with small discussion on what they are for. I'll try and replicate this into the v2.2 ZIP files in the near future.
[Acer Iconia A500] DRTMI:
Used your ADB for 3.0 and it was quick. After I )of the fastest lock on my tab I have ever had, 10 sec lock with 7 sat's. This is the best one yet for me. Thanks.

A gun in the hand is better than a cop on the phone.
[Acer Iconia A500] donkuok:
I am new here and I have the similar issue to lock the GPS. Does the patch work on the 3.2 stock ROM? I just updated it with OTA 3.2.
[Acer Iconia A500] crypted:
If it's rooted or you can find a way to install it without full root...it will work.
[Acer Iconia A500] crypted:
Just thought I'd post an update. The Notes section has been revamped, added, and the Notes / Still Having Problems sections have been consolidated.

I considered adding checksums to the thread. But, I really don't see the need. If people prefer not to trust this, heck with 'em. They can pay $300 for a good standalone GPS unit.

3.1 is still on track.
[Acer Iconia A500] blcklab:
Wow. Running Thor's 14.2 with the 3.0 fix. Got 8 satellites fixed indoors in about 10 seconds. Why wouldn't Acer coopt this? Just amazing.
[Acer Iconia A500] crypted:
Thanks for the feedback. I'm sure at some point some manufacturer will gang rape my work, use it on their devices, and leave me out in the cold without a penny.

V3.1 is ready to throw up. I'm going to do so next week. Reason: I want to wait a bit longer and see if I get some more beta community feedback.
[Acer Iconia A500] pimpmaneaton:
Crypted, I would say it is more than suitable for release. Even though there has been only 3 comments from the team, I'm sure you are not going to have a complaint from anyone who uses 3.1.
[Acer Iconia A500] crypted:
Version 3.1 is released. If you didn't think it could get any faster, well you may be surprised. Beta-testers are swearing to instant locks. My magic tricks sure do pay off!

Pay off? Speaking of that... There have been 30,000 downloads of v3.0. My server has served over 100,000 xtra.bin downloads. And even though I stated that this costs me money to provide,

there's been zero donations

since v3.0 was released. A few bucks really can help defray the hosting and provisioning costs I incur to keep y'all running top notch. If each user gave $0.10, that would be worth a whole dediated server for a year. Just sayin'.

Devs: I request that you notate your threads with which version of my patch you're using. If you include v3.x, please note the cost to your user base. Send me a message if you're using the patch so I can keep track and keep you in the loop of any impending changes.

With that, let me know how well this performs for you. I'm interested whether users see an increase in performance over the amazing speed that v3.0 provided.
[Acer Iconia A500] bytemehard:
crypted,

Ive been following your work. Im running 3.2 stock rooted and flashed your latest Google Specific CWM Flashable 3.1 patch.

Ive rebooted several times because I thought maybe the fast locks were just chance occurrences. Looks like you have outdone yourself.....5-10 second locks every time on fresh restarts with 5,6 or more satellites(Indoors). Gonna try it out more tomorrow evening but so far it is fantastic.

Another thing....I use to have to run GPS Status first to get a lock then go to a navigation app.

With 3.1, I find that copilot, google maps, sygic will lock without the need to run gps status first....I might mention, thats with -use wireless networks- unchecked

Great Work, You deserve some honoraria

GPS lost of lock

Hi all,

I have an A501 with the Taboonay rom.

GPS seems to fix quickly, but, while the GPS status bar icon show that it is fix (not blinking), the GPS apps (copilot and Navigator) loose the location regularly, even outdoor and without moving.

Does anybody knows this issue ? Does this Patch can solve it?

Thanks.
[Acer Iconia A500] crypted:
Are you using it with a case? Which build/version are you using? Have you read through the notes and tried them all?

Notes 5, 12, 14, 15, and 16 may have some importance.
[Acer Iconia A500] sevice-computer:
Yes, I am using a light case (http://www.touslesprix.com/comparer/fiche250899.html), I will try witout.

I am on the Taboonay 2.2 Rom, based on Acer_A501_4.027.15_COM_GEN1 and vilain kernel 3.4 (probably the 3.7, I will check).

So I installed the 3.1 google agps patch with the same un asability.

Notes 5: I will Check

Notes 12: I don't use any 3rd party fix program, only COPILOT or Google Navigator

Notes 13: I checked the configuration of the Iconia with my Galaxy S2.

Notes 14: I will try without the case

Notes 15: I don't know what I have to do regarding this point, any halp please.

Notes 16: As it is an A501, I can not remove the battery
[Acer Iconia A500] crypted:
Cases really can have a profound effect on GPS signal loss and interference.
[Acer Iconia A500] af974:
Temporary sticky as per OP request.
[Acer Iconia A500] beartrap:
Donation gladly made. This has turned my GPS from a dead weight to something that actually works. I now get a fix outside in under 20 seconds and indoors in two minutes. Before, I never saw a satellite indoors and if I did get a fix outside it would take 2-3 minutes. It is nothing close to as good as my Photon that sees two times the number of satellites and fixes in a few seconds inside and out, but at least it is useable. Thank You!

Edit: You really should make this into a market app and charge for it to recoup your costs. It is money well spent.
[Acer Iconia A500] sevice-computer:
REgarding the Note 5, I checked my build.prop and didn't find any entry for the ro.ril.def.agps.conf: what is it for? Do I have to set it manualy (with value 1?)?

Thanks
[Acer Iconia A500] crypted:
What about the rest of your notes? Describe the situation entirely, too.

I don't own this device and can't fully walk through it all. But, other users can help if they see the whole picture.
[Acer Iconia A500] osmera:
Thank you for your work. I have my own configuration of gps.conf, so I checked your configuration to know what are your changes.

I don't see what are your changes, because in fact the only real change is that you use your own ntp server (ntp.derekgordon.com) instead of geografic specific ntp server (like europe.pool.ntp.org) and you provide the same xtra.bin file (for agps) again from your own server.

So I think that people who has quick connection to your server can benefit some few milisecond, but when your server is down they are screwed.

I don't want to sound disrespectful, but I don't really see what are the benefits of using your gps config over the one that is twenty times all over xda and internet
[Acer Iconia A500] crypted:
If you read documentation, you'd see that my servers are ONLY in the 3.x trunk. The 2.x trunk uses my tweaked gps.conf with the best public NTP pool and the fastest Qualcomm xtra.bin mirror available. Both trunks contain supl data for specific servers.

You may think this is just some "new" patch, but I first started providing it several months ago. Since then, there have been nearing 200,000 downloads. Being that my server is used for 3.x, I can say that it's quite popular as well with over 50,000 downloads and serving up nearly 300,000 xtra.bin files.

Further, a large share of the most popular Android ROM's on XDA have incorporated my patch into their packages. Variations exist in which version is in use, but that's up to the dev to update or choose to keep.

EDIT: No person has to use this patch and can choose to favor another. I saw the need to fix a problem I was having, and it turned out to be helpful to thousands of other fellow rooted Android users.

I am useing thor 's rom and 3.1 dont work to well . On factory rom it work much better..
[Acer Iconia A500] crypted:
There are some ROM's that are built without aGPS support properly enabled. I can't fix bad or accidental coding issues from the ROM itself. :o

I do believe some user looked into Thor issues on this thread some time ago.
[Acer Iconia A500] shin lucifer:
I was using Rooted 3.2 Stock, and my gps use to work fine but it took like more then a minute to lock Sat.

I tried Thor's Rom 14.2, its not only fast but the Sat lock is under 20 sec and 9sattelite locked, which i never can get with Stock rooted Rom. I am using Co Pilot as my Nav system.
[Acer Iconia A500] crypted:
And your Thor results are with this patch, correct?
[Acer Iconia A500] shin lucifer:
GPS is tweaked definitely. It stated it in Rom description. Just dont know which version sorry.
[Acer Iconia A500] civato:
Thor is using 2.... version i think.

@crypted, I'm using your v3.1 patch and for me it works fine . But for some reason the 2... version works better for some users of the rom I made.

Especially the apps that need location to work have problems with 3... version.

Anyway Supurb job and I'm using your patch in my rom.
[Acer Iconia A500] crypted:
I wanted to post a few things to the user community.

1. If you're a DEV and are using this in your ROM, please private message me your ROM thread and which version of this patch you're using. This will be useful with tracking, letting you know of updates for your ROM, and supporting users. If you know of this being used in a ROM, and you're not a DEV, you can report it to!

2. Version 3.1 is a great success. Today alone, the xtra.bin has been served 61,441 times to aGPS Patch users. The 3.1 files have been downloaded almost 10,000 times today as well.

3. Updates will continue to occur server-side for v3.1 and beyond. This means that barring any unforeseen issues, v3.1 will stick for some time without a predecessor. As you may have noticed, your xtra.bin and your NTP pool are through me! This means I can keep providing incoming data for you without needing to update the patch to achieve the same changes. Feel free to toss a penny in the pot.

4. Rate the thread! Some threads have been rated nicely. Others have been attacked with +1 ratings by users who failed to read instructions and/or seek help fixing their issues. This gives a bad impression to new users on XDA. I shouldn't be held accountable for hardware, ROM, or other software related issues out of the control of this patch.

5. Let everyone know of your success. If you're using this patch, let people know what ROM, RIL, Radio, and case you're utilizing. This will help greatly in supporting users who want to know what to use this patch with for best results. I only own one device I officially support, so it's hard helping those seeking assistance with those pieces of advice!

Thanks again for being supportive of this project. I'm glad that I could assist many of you with the same GPS issues I was facing. I literally decided not to buy a new GPS for my car after fixing this issue when my first version was release. :)
[Acer Iconia A500] RadFly:
Team,

I copied the gps.conf to ./system/etc instead of ./etc _

and did not save my old gps.conf file... Is this an issue? Anyone have the factory gps.conf file from ./system/etc from the 3.1 gen 2 load that they can send to me?

Thanks!
[Acer Iconia A500] crypted:
If no one has halped you, do a backup and reflash a stock ROM. Grab it, and reflash the ROM you prefer with data still intact. :)
[Acer Iconia A500] BBAHunter:
Please forgive my noobness question but I just wanted to see: I'm running the latest stock (rooted) os version 3.2, kernel 2.6.36.3+ and seem to be able to get sattellite lock in about 10-15 seconds, will this improve anything?
[Acer Iconia A500] crypted:
Honestly, it depends on your conditions not just software in use. Cases, housing, clouds, cities, skyscrapers, etc. It all is a factor.

The second line of the first post of this thread states this is for people with problems.

You can give it a try if you want to; but, back up your original gps.conf and suplrootcert found in your /etc/ folder. If it doesn't help, just copy those original files back into the /etc/ directory.
[Acer Iconia A500] sevice-computer:
Hi, Here are my feed back:

I tried all your recomendations (no case, outdoor, your last patch 3.1)

I launched GPS test and find that:

- the datas are well read by the app

- several SAt are seen, up to 10

- several are fix with a signal up to 42, but are losts du to a down signal under 35.

So, It looks like the quality of the reception is realy low.
[Acer Iconia A500] crypted:
I'd consider a different kernel or ROM. Review this thread to see what many are using successfully. If that doesn't get you going, I'd think hardware issues are a possibility.
[Acer Iconia A500] sevice-computer:
Thank you.

to the community: can you tell me wich ROM you are using with a good GPS reception with A501?
[Acer Iconia A500] crypted:
First, I want to with everyone a very happy holiday season. I will be sporadic with my responses to any questions or comments here on the aGPS Patch threads for the next three to four weeks.

Things to think about if you're having an issue:

Read all of the Notes Section commentary. I wrote that because so many people continually have the same or similar issue that can be easily resolved.

Remember that any GPS tools from Android Market CAN and usually DO overwrite this patch. Therefore, don't use any. The only thing I recommend if you're wanting to get stats is GPS Status, as referenced hundreds of times by yours truly.

If your getting a weak signal: remove the phone from a case and try again. Try a different ROM as CM users and ROMs derived from CM tend to show problems because of faulty ROM compilation, not this patch. Ensure your build.prop has the right variables. Go outside, try again. Lastly, delete the SUPL server section from the bottom of the gps.conf and try without that. Some models with some ROMs have issues with SUPL...outside of my control.

Post and wait for someone to respond. I'll do my best to get on the forum off and on over the holidays.

So, let me give you a general update directed to those 3.x trunk users:

My server has automatically generated an xtra.bin file for your GPS excitement 3,980 times since September 26th when the first beta went online to test it out. :eek:

My server attempts to build a new version every 30 minutes. Depending on what it can decypher from other xtra.bin sources, it provides a totally fresh xtra.bin approximately every 1.2 hours.

My server has served up over 500,000 xtra.bin files to users like you on XDA since v3.1 was released.

My server continues to provide a reliable NTP pool to v3.x users by directing your phones to a handful of RELIABLE and FAST-RESPONDING NTP servers around the world. This ensures you can travel and not have to switch NTP pools.

If you're a DEV and this is used in your ROM, please notify me via private message with a link to your ROM thread. This helps me track issues and keep you up-to-date with any new versions. We both win there!

Finally, if you use v3.x you should remember this isn't free to me. As all of the information above notes "My server...", I foot the bill to keep supplying this data. It's useful as hell to you and to me. :D

Consider donating a little to help offset server costs

AND

to help expand provisioning should enough donations come in. You can donate via Paypal by clicking the donate button next to my username on this or any of my posts. Every little bit helps. If you can't, I understand that as well. :o

Again, thanks everyone. Don't forget to click the Thanks button on my posts should you enjoy what I've got to say...like those amazing numbers cited above for 3.x users.

hey. great work. i donated some money to your efforts. thanks again for your contribution.
[Acer Iconia A500] crypted:
Thanks a lot. I'm glad you like the work and I intend to support it until we all have better hardware and/or software from newer Android and manufacturer iterations. :D

Many early adopters of beta ROM's are claiming this works 110% on Ice Cream Sandwich by the way. And, it appeared necessary for their devices to get functional aGPS support.
[Acer Iconia A500] Johnston212:
Glad to hear about this fix. Other recommendations for marketplace apps give me satellite detection, but not lock.

I'm still trying to get clarification on what patches I should use. Also, I don't know why, but I couldn't get the 1st Method to work. After finally getting the drivers installed, I could not get it to acknowledge the R/W status on my device. I took the Google patch files and pasted them into the specified folder via Root Explorer and no improvement. I did get some improvement when I tried out Fasterfix, but I still only get 2 detections and no lock, where as my Atrix has 7 detections and as many locks.

Any suggestions on what I might want to try? I would love to actually get the GPS on my Iconia to be somewhere near functional.
[Acer Iconia A500] crypted:
I would suggest reading the NOTEs and my post made a a week ago. Fasterix and other Marketplace apps INTERFERE with this patch and render it useless or nearly useless. The only APP I will say is allright to use is GPS Status as mentioned probably 30 times on this thread.
[Acer Iconia A500] Johnston212:
Crud, sorry about that. Normally I try to read through the topic first, but it's been a long week, sorry. I will go back through and re-read them. I normally only use either GPS Status or GPS Test.

Sorry again for my mistake, but thanks as well.
[Acer Iconia A500] crypted:
No worries. But stay away from Fasterfix for sure. It's really just useful on stock ROMs in my opinion. Try outside with GPS Status and a data connection of some sort.
[Acer Iconia A500] Johnston212:
Yeah, I keep it connected to my local wifi all the time, but I get over 2x the reception on my phone and it is sitting right on top of the screen
