  1. Fix confirmed on Freelander I10S MTK6577 based Android in Europe. Before patch very weak signal, and takes 15 minutes to get a lock or longer. (or no fix at all)

    With method 2 and then 1, the phone finds GPS in under a minute. Good quality fix. Even indoor. Like a charm.

    Rooting method used: v18.

    Great how-to nice work!

  2. GPS does not work on my HDC Galaxy S3 i9300 EX- MTK6577 either. Rooting worked perfect. But when using the m44 toolbox (according to the above Methode 1: section 3. Find location based service and click) there is a menu entry *Location* but no entry *LocationBasedService*. And there is no such screen as depicted in section 4 (GPS Pls click on…). Did I miss something or did I install a wrong version of the m44 toolbox (I used the download link stated under above Method 2)?

    When trying above Method 2 I copied gps.conf to /system/etc. There was no such file before, so I did not have to overwrite but just to paste it. After restarting the phone GPS was still not functional. Although the free app *GPS tool* shows up to 10 satellites (but shows it as unused), google maps or other apps cannot find my position via GPS.

    Any hint would be helpful.

  3. Hi, I cant get GPS to work, when using m44 toolbox there is NO location based services option, and when i click YGPS it says ” JE, Can not find some packages. Please report to RD Thx” I have HDC S3 pro ultimate thin

  5. Hi guys,

    I have a note 2 mtk 6577 android phone.
    I used both of the 2 steps but are still not able to see gps fix.
    android 4.1.1 is installed and later i rooted the phone.

    Somebody experiencing the same problems?
    Is there any custom rom to install so the gps function could ever work?

    Thanks for the advice in advance.


  6. Hi Vince,

    Sorry for the late reply, I still aren’t able to find out what is the exactly phone brand.
    Do you know some good app for it?

    I only know sure that is has the same body as orriginal and same battery size and capacity.


  7. We have one HDC H9500 plus phone
    The gps have poor connect or nothing connect

    Can you explain the procedure to enable the GPS functionality.
    I read that need root , can you sendme the link with the instructions

    Thanks in advance

    1. hello xavier,

      unfortunately, i havent found any custom ROM for the phone, anyway, the phone is still pretty new so, ROMS may be released soon

      best regards,

  8. I test this procedure with some gps.conf files

    I test the m44 tool box = “Mobileuncle Tools” and *#*#3646633#*#*

    The gps still not work

    Says “Buscando GPS” or “Searching GPS”

    1. hello xavi,

      the procedure doesnt work 100 percent all the time,
      usually another procedure is to flash your phone to a custom firmware or update your firmware with gps fix

      best regards,

  9. Hi everyone,
    I am from Sydney Australia. I have an ALPS N9500. The GPS is not working can’t even locate me when I use Google Maps.
    I tried to do step 2. When I tried to copy gps.conf into system/etc, an error comes up and says “com.estrongs.fs.FileSystemException: Permission Denied”
    I used Power GPS Search in the MK44 tool and it did help locate me when I use Google Maps, but I still cannot use Navigation. All satellite dots are still red when doing step 1.
    Any help would be appreciated.

    1. hello alvin,

      you may try the following 1. go to settings/location services/a-gps/turn on all about gps or update the epo through wifi – then try using gps test (without wifi) if you get a satellite fix, just make sure you are outside to get much faster satellite connection.
      2. If that doesnt work, then you may try to find flashing the phone to another ROM, update or fix for GPS, you may refer to this link, Btw do you know how to flash your phone?

      Best Regards,

  10. Hi from France,
    I bought a Goophone X7 from Fastcardtech, and I can’t use GPS, no fix, nos satellits.
    I tried a lot of gps.conf, and the two methods of this thread, but still not working.
    All the other applications works well, Web,Wifi,Phone,SMS,MMS.

    Thank you for your help


    1. hello,

      sorry for your problem, gps has always been a problem for china phones because they usually use a-gps (network base gps, use of wifi)
      for network location fix. as of now, there is still no rom fix for the phone, but stay tune, it will be available soon. Or you may update the epo on your location services, try that first.

      best regards,

  11. Hi Vince, thanks for your help, but I wasn’t able to follow settings/ location services/a-gps, don’t know where to update the EPO either… I will try to follow the instructions on flashing another ROM from the link you gave. I might have to fix the camera after flashing, but the only instruction there is to use SP MDT to fix camera… I’ll do more reading 🙂
    Also I did the rooting, but the SuperUser app did not appear, is that normal?
    Thanks again,

  12. Hi,
    I have the ALPS GT-N7102 phone, and have problems with GPS fix.

    I have downloaded the m44 tollbox, and when turning the GPS “on” and goig to the “view” tab, after > 15min I can see 9 red dots for the satellites but none become green or yellow, as the phone/GPS only acknowledges their existence without receiving the location data itself.

    I have turned on the A-GPS and the EPO data is updated, still – no luck to get any navigation software to get satellite fix and run correctly.

    I do hope to find a solution for this…

    BTW, I thought of buying an external bluetooth GPS receiver and try to use it, but I am not sure if it will work… doesn’t anyone of you have an experience with this?
    Of course I will be more than happy to have the GPS receiver fix!


  13. Hello
    I can’t get passed step 2:

    2. Pls click line 2: engineer model for MTK.

    I have NO ‘engineer model for MTK’

    I only have ‘Engineer Mode (Android)’

  14. Hello,

    For those of you that have a feiteng h9500 and can´t have a gps fix look at this;

    The way i´ve done it:

    Entered in engineer mode with *#*#3646633#*#* then went to “location” selectioned “YGPS”, then “AGPS restart” then “Full”.
    Then left it at open sky for 20/30mn until it get a fix, most of sattelites appeared green.
    Left the engineer mode “back key”, entered google maps and voilá gps fix on the spot.
    Done it with original rom, rooted and cwm installed.

    Thanks to this guy: Publicado por Gus



  15. at least on my hcd N9500 with mtk6589 the gps doesn’t work, it will only work with data, but not with out it.

    if u want a phone with a strong gps antena, DON’T get mtk phones (at least for now)

    Everything else on the phone, works great.

    1. Hello Poncho,

      Its not on the CPU that’s the problem, unfortunately, the gps of china phones are not particularly a priority when it is made. Because GPS is seldom use in China, GPS are not properly configured. From my experience, UMI and HDC brands have this problems as well as Star, either weak GPS or non working at all and needs an firmware update in order to fix. For example, my HDC Galaxy S3 EX (Dual COre version) which was my first phone, by the way is the same with Star B92M (rebranded) has a very weak gps takes 7 to 8 minutes to lock in without wifi or data support. I’ve also heard that somebody who made a hardware modification (adding external GPS antenna to his UMI X1 and it works like a charm. BUT, other more expensive and popular brands like that of Lenovo, Huawei, Meizu, Oppo (find 5), ZTE (their GPS work Just fine), GPS problems are on a case to case basis especially on clones.

      Hope this helps

      Best Regards,

  16. Hi Vincent,

    You´re right on your last comment, with data connection (wi-fi or 3g) gps lock on is much faster. When i go into engineer mode on my feiteng if i have wi-fi disabled it says “SI-Req request failed due to no network”, when i enable wi-fi it starts communicating. A friend of mine has a sony xperia z, he always has 3g on, when i saw the specs on the phone it says agps on the gps caracteristics, so its right to assume that the sony gps only lock on with data connection?
    You´ve also referred to a firmware update to improve gps, can i find it on the net the firmware update for the feiteng h9500?

    i have a problem with my new FAEA F2 and its GPS.

    GPS is not working at all. I used method described above, but without success.
    I updated GPS fix data, but i see only “Searching”. So in Uncle tools (and in all other app with GPS) i can see only red satellite position, no one is green, no one is “catch”.

    Can anybody help me?

    1. Hello Fazlay,

      Its good news that your GPS worked,

      2. in order to get rid of the preinstalled Chinese Applications, you need to root the phone to be able to do this.
      3. may i know what tts means?
      4. You can install an application if your default weather app is not working or is in Chinese
      5. Have u tried uncle tools on mobile uncle tools?

  22. Hi hun, i tried downloading m44 tools but i didnt find them on google play but i have mobile uncle tools but when i go to engineer mode i only have engineer mode (android)
    Is there a way to still make the gps works? i downloaded the epo file. Btw my phone is samsung s4 clone (Alps gt-i9500) mt6572

  23. Thanks Cris CTS,

    I just bought Lenovo A390 (Mediatek MT6577)

    I was unable to fix the GPS. Rooted the phone and tried everything but nothing worked.

    But when I changed gps.conf & epo_conf.xml as suggested by you and rebooted the phone, now I am getting the fix even with No Data connection.

    Thanks for your great help.

    I used NTP SERVER: for my country India

  24. I could get a lock on my n9006 galaxy note 3 clone but would lose lock constantly and made sat navigation useless. I tried all the above fixes EPO/AGPS, mobileuncle and nothing worked. WHAT DID WORK is placing my left index finger on the rear top left of the casing whilst the phone was in GPS Test. Upon doing that the GPS sprang was registering a 30% gain on the previous reception. Having a bit of bacofoil rolled up and sticking out of the top left of the case did the same trick. I believe all the aboves fixes do are allow the phone to know where the satellites are but that ALL the MTK phones are furnished with a defective rubbish cheap GPS antenna. All the chineses sites pushing the aboves fixes are doing so just to try and stem the mass return of their phones. Mine is heading back to the retailer as we speak.

    1. HEllo Paul,

      thank you for your advice and guide, it really helps. Anyway, mtk actually have good gps performance, its just other china phones have poor gps antenna placement or reception. I have used mt6589, mt6582, mt6589T, not on HDC but on phones sold in my country, and their GPS works fine. HDC, UMI, Jiayu had this common problem last year and i think there is a guide from a french user (UMI X1) who modded an external antenna and GPS works fine or even better. Especially with clones, this problem is prevalent, Although on the new mt6592, most of the problems have been fixed.

      Best Regards,

  31. Hi, I have a brand new Vernee Thor smartphone running Android 6.0, and I found out that my GPS is not accurate at all. When standing in one place outside I can see the dot on google maps move around my position, sometimes nearly 50 meters away from my real position. When I go walking and record my position, and then check the route, it seems not to follow the path I walked and sometimes it shows all kinds of ZIG-ZAG patterns.
    Would the method described above fix this problem on this phone? Thank you in advance for your answer.
