I read on another forum that the ICS update has been posted here as a zip file, but I haven't looked for it yet in the index. Those who have updated OTA and mentioned the GPS say it locks much paster now. One member said he locked 6 sats in just a few seconds.
[Acer Iconia A500] crypted:
So for those using OTA's or OTA bases, I might finally be marginalized completely! :o
[Acer Iconia A500] drharisis:
could anyone post the gps patch of new ossicial rom??
[Acer Iconia A500] crypted:
So you want someone to post some patch made by another person here? I'm confused.
[Acer Iconia A500] drharisis:
hehehe....I mean you crypted....please fix it....
[Acer Iconia A500] mknewman:
Best I can tell ICS broke GPS completely.
[Acer Iconia A500] crypted:
Sad to hear...

If you can private message me a link to a custom ZIP file containing all of /etc/gps/ and /data/gps along with the original gps.conf from /etc/ if there is one, I'll see what I can do.
[Acer Iconia A500] pacificwing:
You aren't, by chance, using Thor's rom are you? If so, try flexreaper or another one.

Thor's rom broke the GPS on my device too. I asked about it in their forums and his response was something along the lines of "it works on mine. you're on your own".

Anyway. Try another rom. It might work for you.
[Acer Iconia A500] mknewman:
I'm on the stock ICS OTA release with root and unlocked ROM.

I'll make up a zip for you.
[Acer Iconia A500] drharisis:
:( i WAS THINKING that quickgpsfix is solved on official release...Running flexreaper I had really quickgpsfix 3 weeks ago when I extracted a libs.so file ondata/gps(it was locking 8 sats on a few sec)..Unfortunately file expired and eventhough tested build1 or 2 I had never again a quick fix
[Acer Iconia A500] crypted:
Thanks. I'll try to make something beneficial if at all possible.
[Acer Iconia A500] maris__:
To my opinion, the reason for the time until sat fix is getting worse is just the fact that the lto.dat files that are packed with the diverse ROMs are outdated. So I guess the quickest soloution for this problem is to download the latest lto.dat file by our own. Following crypted and pacificwing's suggestions I am using the following two commands in the <hal> section of the gpsconfig.xml file:

ltoFileName="lto2.dat"

acLtoDir="/mnt/sdcard/Download/"

In my Opera browser I have bookmarked "gllto.glpals.com/30day/v2/latest/" (thanks to pacificwing for the link). If I know that I will use GPS, I am just downloading the actual version of lto2.dat; then I always have the same quick sat fix.

With best regards, maris
[Acer Iconia A500] crypted:
It's quite annoying that the system will not auto refresh the file like it's supposed to. Yay for Acer I guess...
[Acer Iconia A500] maris__:
Indeed. I guess it is something basic that prevents the Acer tablets form updating. No idea what.
[Acer Iconia A500] BakaNeko59:
It shouldn't be that difficult to use SManager to run a shell script that does the download for you, but my tab is on the fritz right now and I lost the work I was doing on that. I remember trying to use wget with the download address, however, and it didn't work...

I'll revisit it once I get my tab working again...
[Acer Iconia A500] crypted:
I do not believe wget is an available option. Try fetch or lynx instead. I don't know, though.

A script would be simple. You could use an update variable, or simply rm -rf the file and re-download it.
[Acer Iconia A500] drharisis:
could you help me??I have some answers..How i set these commands in the hal section??(opening with root explorer it says that is read only file...Also must I delete the other commands on thos section???Where I have to put the downloaded lto file???)
[Acer Iconia A500] drharisis:
I simply downloaded the file from the url you posted and set it to data/gps file and renamed to lto.dat....worked great....Its at least a temporary solution...until a patch which will autodownload the new file will be fixed..
[Acer Iconia A500] maris__:
Yes, this gives you the same result.

Best regards, maris

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.
[Acer Iconia A500] crypted:
Official support has is now available for more devices:

Samssung Galaxy S III (AT&T, Rogers, Bell, Telus)

Samsung Galaxy S III I9300, I9305

Asus Transformer TF300T

Motorola Droid X2

Samsung Galaxy S 4G

If you appreciate this growing work, always consider clicking the Thanks.

Remember that I pay monthly hosting fees for the space and bandwidth necessary to keep this patch working on the backend. So, please consider donating a few bucks if you're a user. All donations go directly to the patch provisioning and there is absolutely no overhead to benefit me.
[Acer Iconia A500] 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!
[Acer Iconia A500] crypted:
Not a problem. It's great to see people enjoying and benefiting from this work. Beta-testing for v2.0 begins tomorrow. Expect a release early next week.

I've been accused of working "voodoo" and running a farce in fixing GPS issues. But, you and the 99.999% of users show that such accusations are simply wrong... Maybe those couple of people should actually try it instead of saying it just won't work. ;)
[Acer Iconia A500] mistahd33:
Update on my testing.. it was slightly better this morning after leaving gps check all night, but its still bunnyhopping me down the road in nav programs, maximum refresh time seemed to be about 10 seconds... it gets a fix at the moment within about 3-4 minutes quite consistantly which isnt that bad, and can see plenty of satellites, its just the refresh time which is an issue for me.

I AM however having some wierd issue at the moment when my iconia has somehow unrooted itself and reflashing the rooted honeyvillian kernal did't fix the issue, I'm about to do a full wipe and start again..

What roms are people using where the gps is working well??? (preferably A501 compatible rom which allows me to use my 3g simcard slot.. thats the reason I've been using honeyvillian kernal v3.4).
[Acer Iconia A500] josinpaul:
I am using stock 3.1 rooted and with busybox. I can get lock on in under 12 second to a min of 3 to 4 sats. I am also using GPS status.
[Acer Iconia A500] crypted:
All: thanks for helping eachother. Please keep doing so. I do not have this device to recommend ROMs and kernels for.
[Acer Iconia A500] mistahd33:
in gps status, once locked there is a LAST FIX value.. can you tell me roughly the average number of seconds that this value increases by? the refresh rate of that value is the issue for me... I need to get it down to about 2 seconds consistantly... as I type this, (although I AM indoors) the average refresh rate is about 15-30 seconds, earlier today in the car it was down around 3-4 seconds and was nearly bearable.
[Acer Iconia A500] josinpaul:
One second in out doors, in my car it is 2 seconds to 3 sec.
[Acer Iconia A500] anubis13:
this didn't fix anything. my GPS is still garbage
[Acer Iconia A500] eersfanpilot:
CMR flash did not work for me either with the Zip.

I got this:

E:Error in /sdcard/worldwide1.3.zip

(Status 0)

Installation aborted

First test after moving the GPS.Config manually:

Upon starting GPS Status App within 10 seconds I saw 5 sat's

After 20 sec's I was getting a prelimanary Lat and Long off of 4 of the 5 sat's

Within 30 seconds I locked 3 of 5 and picked up sat's 6 and 7.

Within 2 min I turned the screen off and back on and all sat's dropped out but 6 came back with 4 locked in under 10 seconds.

I have a flight coming up on Sunday that will allow me to get a solid lock with Wifi first then move to GPS only. I will run the app during takeoff and see how high the locks hold.
[Acer Iconia A500] crypted:
Some suggested in this thread that it is heavily dependent on the ROM. One user stated that when his was plugged in and charging, he had no GPS at all. Local surroundings matters. If you're in a cement building, eh, probably going to have issues.

Could you elaborate on what you are running for a ROM, a kernel, and so forth? Maybe specify where you are testing and the environment surrounding you?

---------- Post added at 06:15 PM ---------- Previous post was at 06:14 PM ----------

Yeah, it appears that most Recovery setups for this device don't support the ZIP. I'll be interested to know how it goes. Do you consider the results you had thus far to be an improvement or is it worse?
[Acer Iconia A500] mistahd33:
omg then, sounds like a might have been sold a dud, typical.. I'll get my friend to test on his a500 on the rom im on.
[Acer Iconia A500] jjj666:
Have beening use this for a couple of days now, works better. My GPS usually locks in 15 seconds with about 8 to 10 SATs.

Thanks!
[Acer Iconia A500] eersfanpilot:
It is definitely an improvement over the GPS signals I was getting. I was also doing the testing indoors in my apt where before I would be lucky to get a lock on 2.

Thanks for all your work you put in trying to make this better. It seems to be paying off for most that use this patch.

This doesnt work in taboonay 2.1b for me. What could it be?
[Acer Iconia A500] crypted:
Check earlier thread posts. A couple of users talked about the ROMs they use and their good results. Also, indoors in cement buildings make it difficult. Any kind of case can cause bad results. Lastly, a user said he had bad results when it was plugged in and charging.

Poco a poco!!! ;)
[Acer Iconia A500] Luescoff:
I have also tested with taboonay 2.1 and it doesn't work as suggested. So I restored my stock file. But, thanks for a great work!
[Acer Iconia A500] crypted:
Some ROMs do not support aGPS because of deletions or incorrect variables in the code. This was an issue for CM7 nightlies for a while. So, just something to consider.

Thank you crypted. I applied this patch yesterday and it works. I have to make a little modification though, I deleted all ntp server except asia (I'm in indonesia) and deleted the line /data/xbin.

Using taboonay 2.1b with Thor 3.7
[Acer Iconia A500] crypted:
Nothing wrong with a little modification to suite your needs. ;)

I'm living in Vietnam so I could use your modified file as well, I guess? If so, could you please send it to me please :) I'm not good at IT so your help will be very appreciated ;) thanks in advance
[Acer Iconia A500] crypted:
I recommend using mine first. If it doesn't work that well, you can use his suggested change to the NTP servers in the gps.conf to reflect asia instead of global.

OMG, this thing rock :D First use and I had fix after maybe 5sec. Veery nice ;)

I use the 2.x google version.

I'm currently using yours :D I rarely have to use GPS, anyway :D Anyway, good work Crypted ;)
[Acer Iconia A500] sergeantosborne:
worked... not at first... I left it on all night and woke up and no sats were found... then I took it outside and it locked onto seven right away... now it works inside and out... the satellite signals are not as strong as that on my Galaxy phone but acceptable... finally! Thanks for the fix... this solves my biggest frustration with this device.
[Acer Iconia A500] shaun298:
My stock gps.conf file has 3 lines, Im in US. Tried the gps posted here, but went back to stock. It worked fine but I though the stock gps was faster and overall better for me. I had good gps to start with. And did clear gps for test.
[Acer Iconia A500] crypted:
Like I said at the top of the first post, it's for people who have problems. You're a lucky one by not having any real issues with your GPS unit. GPS has been one of the biggest setbacks for Android users with custom ROMs.
[Acer Iconia A500] AkiraBBQ:
Thx for the idea, but I think many entries and values in gps.conf are either bogus or invalid. For example the value "FQDN" is just a place holder for a full qualified domain name. An invalid host (like "FQDN") will only slow thing down when the system is trying to resolve it. Also supl.google.com does not response on port 3425.

The crucial lines which affect a-gps performance are:

NTP_SERVER=

XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin

XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin

XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin

XTRA_SERVER_4=http://xtra4.gpsonextra.net/xtra.bin

SUPL_HOST=supl.google.com

SUPL_PORT=7276

SUPL_SECURE_PORT=7275

NTP is the time server. A fast response NTP server will greatly help, try to use a server which is nearest to you, or just use the generic ones like europe.pool.ntp.org, asia.pool.ntp.org or north-america.pool.ntp.org . I am not sure if those ntp.org addresses have multicasts though. Two or three entries are already enough for failover.

IMHO, the gps on A500 are not as sensitive as many other android phones, and the compass is indeed pretty poor. The compass is prone to get interfered by nearby metal objects. GPS will have a hard to get a lock if the compass points to the wrong direction.
[Acer Iconia A500] crypted:
FQDN will be provided by libs. AT&T is where this matters. Hence, it is in the AT&T build.

You're citing a port that is not in use in the gps.conf I provide, so I don't know what you mean for Google.

Yes, lot's of fail-safes to make people feel more at ease. You would be surprised at the fear out there. You really don't need anything but pool.ntp.org as you'll get quick DNS and NTP responses no matter where it's coming from. The NTP protocol uses just a few bytes to send the time. Thus, NTP packets are small and fast. I'm building my own NTP pools for v3.x. Yay.

XTRA redundancy is not as important as it used to be. The xtra1 server is used in standard configurations on all Qualcomm devices. It is overloaded. I dropped it and started using their secondaries. This brought dramatic speed increases for downloading the aGPS data.

V2.1 uploading now. New install methods to make it even easier. Will post in a bit.
[Acer Iconia A500] crypted:
v2.1 is out

Everyone, the latest version is out. It's a minor update.

I put a changelog on the thread now. It's just above the Notes section.

Also, there is a new installation method. You can install via a batch script. It uses adb push behind the scenes to install whatever patch you select from the menu options.

Hi everyone, I'm in Taiwan and just got the Tab A500 few days ago! (this is my first Android based toy :D)

Really a newbie comes to the Android system... but decided to flash a custom ROM on the first day. (Thanks to all the talented people here!!!) after the custom ROMs, I found out that my GPS had problem on locking.

I have used method 2 trying to fix the GPS problem, but came out without any luck. Tried the 2.0 & 2.1 Google Specific / GPS.CONF only, Worldwide 1.3 & 1.2.

Currently with Lightspeed_1.0.5 [HC3.2] ROM, Could anyone help me? Thanks~
[Acer Iconia A500] crypted:
I don't have the device, so I can't get specific. Review the thread and see what ROM's others said they were using. ROM's matter at times.

Also, a user in China reported that he must unplug the device before GPS can work.

Cases/enclosures matter. Are you testing in an open area away from really tall buildings? Explain your environment.
[Acer Iconia A500] noeybou:
Thanks for the reply, before the custom ROM, i was able to get the GPS to lock on my balcony (i live on second floor). After flashed custom ROMs, I couldn't. So, I decided to take the A500 outside and try it out. Guess what, after about 6~7 mins. It finally locked on. The signal was weak though... Anyways, I'm gonna tried the patches here to see if it would be more stable or not. ;)
[Acer Iconia A500] crypted:
This patch should work just fine. I recommend the Google build. However, some ROM's have issues with GPS. The developers will comment out specific pieces of the code before compilation that are needed for aGPS to function. Usually it's done by accident. My patch cannot overcome ROM issues.
[Acer Iconia A500] crypted:
I have released v2.2. Changelog is updated. A new version is out for LG phones. It might work with others just fine as it is only a change in SUPL to LG servers.

Still working on v3.x I promise!

Thanks for the files,

the files have to be copied to the ETC or ETC/gps ?

Well, the patch works regardless. I don't have this device, so I can't see the directory. If someone could send me the file, private message me.
[Acer Iconia A500] rredlin:
I guess I am not doing as well as I thought, it seems that on a fresh reboot, gps locks quickly and google maps or nav works awesome, but after closing these programs, when I open them again, the gps does not launch, no little gps icon in the tray, nor will it lock, even after 2 hours!

I have tried removing the whole gps folder and extracting to etc/ and even making a new gps file and extracting the 2 files.

I kinda really need this work, any ideas?

Should I try the old world wide version?

thanks
[Acer Iconia A500] crypted:
Well it wouldn't be the GPS patch causing this. The patch replaced the gps.conf. You used it and successfully had a GPS lock and were able to use the programs as you described.

That signals something else causing it to screw up.

I wonder if you have a widget or a background app that tries to use GPS while those apps are running, isn't able to, and keeps a ghost process running...
[Acer Iconia A500] rredlin:
No Widgets, but I shall dig deeper to try and see whats running the background.
[Acer Iconia A500] crypted:
There are apps like Advanced Task Killer. Or in terminal, "ps aux".

As of right now im back to stock. Doesnt seem to do the same thing. After lock and useing maps or nav, then closed, it locks again just fine, just slow as hell :'(
[Acer Iconia A500] crypted:
With the patch applied to stock? Which patch version/build?
[Acer Iconia A500] rredlin:
not stock rom, sorry i put the stock gps conf back in the etc/gps. but yes it still did the same thing. after using the gps just fine on a fresh reboot, close it, then reopen only to find that it would not launch the gps, no icon and searching for gps for longer then 20 min.

I have tried this with the google 2.2 as per your suggestion, and also with the ATT as per my inconia is through ATT with 3g and wifi.
[Acer Iconia A500] crypted:
So there's a failure of both mine and stock gps? Try another ROM maybe...
