Exclamation AGPS Patch Wildfire S 3.1 & 2.2 | GET BACK TO RAPID GPS LOCK, CAN LOCK ONTO MORE SATS

AGPS PATCH

REVIEW THE WHOLE THREAD BEFORE POSTING QUESTIONS.

List of officially supported devices is at the bottom of this post.

Use this if you're having GPS issues (unreliability, no functionality, etc.)

This patch provides a worldwide solution to GPS issue for multiple devices. Using a general ROM without this has resulted in 10+ minutes of GPS delay. Also, GPS lock kept being lost. By using this patch, most people experience a GPS lock within 10 seconds (2 - 20 seconds range can be expected). Typically, a device using this patch will lock onto 7 - 9 satellites. Users have reported up to 11 satellites being locked at once. Without this patch, the average satellite count is 4.

HOWTO INSTALL: (Remember to make a backup. See Notes section for what this patch does.)

Method 1:
1. Download the "ADB Push Installer". This contains all versions for the latest build and old v1.3 versions.
2. Extract the files into a specific folder.
3. Plug your device into the computer and get it ready for adb pushing. Nothing out of the ordinary required.
4. Open the batch file called "ADB Installation Script - RUN THIS" if you use Windows. Otherwise, run the Linux SH script if you use Linux.
5. Select the version you want from the list.
6. Follow the prompts to reboot. You're done.
4. Review the NOTES section.

Method 2:
1. Download the patch
2. Copy all file(s)* into /etc/ of the system (not sd-card) using ES File Explorer, Root Explorer, or some other form. You must have SYSTEM set to Mounted and Root enabled. Check your explorer app's SETTINGS to do this.
**Files will be: gps.conf & SUPLROOTCERT -OR- only gps.conf for NO-SSL builds.**
3. Reboot the device
4. Review the NOTES section.
*Files are located in the /system/ folder of the ZIP. Do not copy the other directories or folders.

Method 3 (easiest if you use a compatible version of CWR or CWM)*:
1. Download the patch
2. Boot into CWR (Clockwork Recovery)
3. Mount /system/ partition (on the main menu, select the "Mounts and storage" option, then "mount /system")
4. Flash the patch (on the main menu, select "Install zip from sdcard," then "choose zip from sdcard," and find the zip and select it)
If you receive "(Status 0) Installation aborted" this Method will not work for you. Use one of the other methods.
5. Reboot the device
6. Review the NOTES section.
*This was built for and works on Inspire 4G and DesireHD versions of Clockwork Recovery. The Google CWM Flashable Build has binaries known to work with CWM on the X8. It may work on other devices. Please message me your success if you try and flash with recovery version and phone model as part of the message.


Downloads:
SEE THE NOTES SECTION (PARTICULARLY NOTES 1,2, & 3) FOR ALL SORTS OF INFORMATION AND FACTS ABOUT THIS PATCH, WHAT EACH BUILD IS FOR, VERSION DIFFERENCES, AND KNOWN ISSUES WITH SOLUTIONS.

Recommended Builds (pick either):

Rules For Posting Questions:
  1. Read the Notes Section first. I will refuse to answer questions that can be answered by some reading. If it is based upon something in the Notes Section, REFER TO THE NOTE when asking.
  2. Answer the following questions: What ROM you are using?, What kernel are you using?, What GPS apps you have installed?, Where is your general location?, Are you using a case?, Has your GPS worked fine before?, Does it work fine with some apps and not others?, What else happened around the time your GPS stopped working? -AND- Have you reviewed the Notes Section?
  3. DO NOT criticize the user of custom third-party NTP pools and xtra.bin data as dangerous. You obviously HAVE NOT read the Notes section OR reviewed the concurrent branch 2.x to discover it offers the standard NTP pool and Qualcomm-based xtra.bin server.
  4. Don't indulge yourself in ignornat posts. Provide information that may be relevant to helping. Simply stating "this stopped working" or "I can't get it to work" helps nothing and only annoys other readers AND those who may be willing to help you just will not do it.


NOTES Section:
  1. This patch will work with virtually all Qualcomm, Android phones and has been reported to work with other chipsets as well. That means hundreds of devices could see a benefit to GPS performance from this patch.
  2. This patch has various objectives to ensure stability and efficacy with GPS. Locally, the patch will replace your /system/etc/gps.conf and your /system/etc/suplrootcert if you have this file. You can compare the difference in what you have to this one to get an idea of all the changes. V3.1, onward, contains section descriptions for variables in use. Most notably, starting with v3.1 the aGPS Patch uses my own central NTP DNS pool and my own central xtra.bin server by default. The xtra.bin does have fallback servers should mine fail. But, that is very, VERY much an unlikely scenario. These two imperatives allow for better stability and speed by providing top-rated NTP servers and prime-routed network access to transmit the xtra.bin to your phone.
  3. I recommend the GOOGLE BUILD of all trunks. However, you can use any build with any phone. You may have good luck with specific builds that do not fit your phone or carrier criteria. If you're curious, test it and see.
  4. This works with ANY ROM unless the ROM has aGPS and/or GPS disabled in the code. This happens with CMx nightlies and some betas! I cannot fix this, neither can you.
  5. Remember, this has to be reflashed when you update or change ROMs.
  6. Short patch history: The 1.x trunk only flashed a modified gps.conf file which relied solely on Qualcomm and NTP.ORG. Starting with 2.x, a gps.conf and a matching SUPLROOTCERT file for SUPL server authentication is included. The 3.x trunk offers the same as v2.x but adds better sourcing for NTP data and for the xtra.bin file; it utilizes my own server to do so.
  7. Why toss out SSL?Whether or not you have a current SUPL certificate is questionable. Some have expired. Some will expire soon. Either way, the servers may provide SSL access without proper certificates depending upon configuration. That aside, I have found that SSL and secure communications over data networks slows the response times. I see no reason to use SSL for location information. If someone has a logger to obtain your location, SSL will not assist in stopping it. The bad app will continue to obtain your information by "stealing" it and you have more problems than a simple SSL-SUPL communications leak.
  8. NO-SSL Builds will not have a SUPLROOTCERT because these builds do not use SSL. The SUPLROOTCERT is a certificate used for authentication of SSL connections. There is no need for this file for the GPS at this point.
  9. IF you have issues with v2.x or v3.x, your ROM might require more variables. Try the old worldwide v1.3 version in this instance.
  10. IF you still are facing issues, it might be that your GPS hardware is very much outdated. Try any "Alternate" build to see if this helps.
  11. CMx ROM users may not experience benefits from this patch. However, we have had good reports from CM users with one negative one. Remember to do all of the steps when flashing and the following notes are important too!
  12. Reports indicate that this patch DOES WORK with the next iteration of Android, Jelly Bean. This patch has worked from Android 2.2 (Froyo) up through Android 4.1 (Jelly Bean). Therefore, it works with all iterations on the market. I will remove support as soon as it is confirmed to NOT work with a new version of Android.
  13. Reports show that certain ROM's including some CM builds require a modification in the build.prop. You need to change "ro.ril.def.agps.mode = 2" or "ro.ril.def.agps.mode = 0" to be "ro.ril.def.agps.mode = 1" in order for aGPS to properly function. Only do this IF YOU ARE HAVING PROBLEMS after attempting the standard patch.
  14. Your phone "learns" about the individual GPS satellites. This is part of the aGPS design. Don't be surprised if the first time you use GPS Status that it takes 20+ seconds to "lock".
  15. I have read a lot that indicates that it is best to let your GPS run using any application for a while to "learn" aGPS information. I let GPS Status run for about 10 minutes (it has an option to disable the screen timeout, which I do) each "first time" to learn. I say each because I test a lot of tweaks and fully reset/delete GPS cached information to start retesting.
  16. Remember, this has to be reflashed when you update or change ROMs. Each ROM will have its own gps.conf, normally not suited to all devices.
  17. I use GPS Status to test my signal strength. It isn't 100% accurate, but it gives a very good sense of how the GPS is performing.
  18. If you're wondering why GPS is slow on certain apps? Or, you show up as on a street when you're 6 meters away from it? Well, those apps process GPS data differently which is out of anyone's control except the app developer. Certain apps will force your location to a street until you pass the app error threshold. Food for thought.
  19. DO NOT USE ANY OTHER GPS FIXING APPS with this patch. If you do, and you still have problems, I cannot help you. A number of these Apps will overwrite what my patch does dynamically.
  20. Variables are described starting in v3.0. Open up gps.conf in a text editor to read about what variable sections are for. It isn't in-depth, but should be enough to help you get a general understanding.
  21. Still having weak GPS reception? Take your case off. Cases have been known to affect signal, though some argue against it. Personally, I get 3 more sat's when I remove my case.
  22. There is a reported variable that can cause some GPS units not to work as well as it should with this patch. This is very odd as it's hit-and-miss and only seems to cause problems on less than 10% of handsets. This doesn't mean it screws up anything! It's possibly an older piece of GPS hardware incompatible with this variable. Have no fear, v1.2 will remove this variable for the worldwide version. This issue is more prone to occur in DHD.
  23. Tried taking the battery out for 30 seconds? Some have reported that their phone required the battery to be removed. First, power off the device. Second, remove the battery for 30 seconds. Third, put it back in and give it a try. I cannot explain this except for possible cache clearing.
  24. Some Inspire 4G and DHD devices have hardware problems. There is a known problem that the spring connectors to the GPS antenna sometimes are out of place or quit touching. http://forum.xda-developers.com/show....php?t=1101066 provides a video on self-repair.
  25. An error in flashing this patch means that this method will not work for you. Use one of the other methods for flashing this patch. Don't ask why or for a fix. There are hundreds of variations of recovery systems and update binaries. I do not have the time or desire to support them all. This is why I describe other install methods. Reference error: E:Error in /sdcard/android apps/agps.patch.google.build.nossl.v3.1.zip (Status 0) Installation aborted.
  26. Location is way off? Like, not near you at all? This means your GPS is not actually being used. Try the following to resolve it: Goto Settings -> Locations and disable ALL options. Reboot into recovery. Clear Cache and Dalvik Cache. Reboot normally. Go back to Settings -> Locations and only enable GPS. Reboot once more and try your GPS again. If this didn't work, did you read all of the Notes such as the one about the battery or RIL?
  27. Donations: If you wonder why I asked for donations, it's simple. Users of v3.x are gaining extra, noticeable benefit over v2.x. This comes at a cost to someone. I pay the bills to provide a reliable data setup to transmit the xtra.bin data file and to provide the top NTP SERVERS in one DNS pool. To help keep this going, I just ask for the user to consider a donation. Nothing more, nothing less. Thank you for your consideration.

Thanks Section
While this has gone a long distance since its inception, I want to still send thanks to Angeldeath for permitting me to take his early work and start tweaking it for HTC Inspire 4G users. This inevitably led to what we have here today.
Thank you to all those who joined and participate in the testing community. Without their help, I couldn't get enough data to know how well this works on different devices and in various regions of this planet we call Earth.
Thank you eagleeyetom, husky69, and tamagotono for their work in building an ADB pushing environment for Windows and for Linux respectively.


If you are happy with the patch and find this thread useful, please consider pressing the "Thanks" button on any of my posts on this thread. You may also consider rating this thread with five stars if you're satisfied. You may do so just below "Search This Thread" on the right-side at the top of this post. Donations are appreciated (See last NOTE)

Currently: this is a tentative supporting thread for my aGPS patch. Assuming more report success, I will start officially supporting this device.

Please let me know your success rates. Thus far, a few people have sent me messages and emails stating that this patch works great on this device.

As such, I'm thinking it would be good to provide this officially for this device.

This has been used on over 40 devices successfully. I don't offer official support for all devices. Rather, I offer official support once users convince me to do so for that particular device. That happened here.

Statistically, here is part of my post from mid-December on all official threads:
Quote:
So, let me give you a general update directed to those 3.x trunk users:
  1. 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.
  2. 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.
  3. My server has served up over 500,000 xtra.bin files to users like you on XDA since v3.1 was released.
  4. 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.
Enjoy!

Dude i have question about the Patch

1st i already done this on my Wildfire S : http://forum.xda-developers.com/show....php?t=1239713

Im with the Latest Stock EU 2.3.5 ROM and i must to tell you
that after i donte this gps.conf file now when u turn on my GPS even from cold start i need 2 to 5 seconds to Lock the Satelites

But i saw just your pach now and wondering to try it too.

So what does the patch do exactly?

And can you tell me witch one to install i mean will be better for me and my stock ROM?

Thank you in advance!

P.S Now im cheking what is writen inside your gps.conf file if you need i can give you mine i don`t know do is posible the GPS to lock for 1 seconds but im sure that my gps.config work because im using GPS all the time and befor to edit it i waiting 3 times more for satelites. this is why im interesting in your pach too
HTC ONE A.k.a (M7) S-OFF, Rooted, Unlocked
Android Base 4.4.2 KitKat ARHD 51

Good question. First, that user used my work as a base for his article. I spoke with him on that because no credit was given. Apparently, someone else gave him my work and my explanations to be a basis and didn't inform him that it was verbatim something I said.

However, my patch does more than what is discussed there especially if you choose the 3.x trunk. The reliance on NTP.ORG is not the most prudent choice. So, I created my own centrally controlled DNS pool for NTP servers that have proven to be reliable across cellular networks. NTP.ORG pools thousands of servers that do not always have the best networking transmissions. This causes issues to phones who are served that NTP server by NTP.ORG.

Next, v3.x uses my own centrally maintained xtra.bin file. My server and its mirrors have proven to provide users with that data file much faster than Qualcomm servers. Further, we use a series of scripts to ensure that we are serving the most reliable file. Sometimes, Qualcomm files aren't reliable enough for our tastes. We replace it with a custom file when Qualcomm falls below a minimal reliance threshold.

Literally, a large number of ROM developers bake this into their ROMs on already supported devices. From that, thousands of users operate with this patch daily. My servers are sending xtra.bin files and NTP server information constantly.

I always recommend the "Google Build" to all users. Most ROM dev's use the 3.1 Google Build in their ROM's at this time. Other builds are available for those who want Network specific options.

The alternate build is for those who have an old Qualcomm GPS chipset that cannot handle particular data processing. This resolves that problem.

My GPS is working good but I'll test this tomorrow out of curiosity.

I stumbled upon your thread a couple of weeks ago and posted a link to it in a GPS thread for wildfire s, just never got round to trying it.

Thanks.

Let me know how it goes. I'm looking forward to supporting more devices officially. Right now, I'm on target to do official support for 7 more devices including this one if all goes well.

OKay thank you i already install Patch 3 Google you recomend will chek and will see how its working and will write a coment here



TEST: I install the Google one that you recomend And i test it outsite from cold Start what i mean is just restart the device and RUN the GPS after 6-7 Seconds IS done and what i saw i have Locked 11 Satelites this is alot i think.
So this is when i run the GPS for 1st time after sistem rebot
After this if i run it again there is not time to lock the satelites i mean the satelites are lock for 1-2 seconds almost imideately after run the GPS

So im guessing your pach is working Because the result is cool and 11 Satelites is serious

How fast received data is "expiring" ? I'm asking this because my phone rarely has internet connectivity while using gps (mobile internet disabled).

The xtra.bin data files upon creation are valid for 24 hours. The least amount of time from my server (v3.x uses it) is 23 hours if you download it right before rebuilds.
