the fix works on all phones that are rooted

I hope it can help you:

In my rooted Morotola Razr D3 (XT920) firmware 2_32D_2009 (Brasil) it´s not possible to enter MTK Engineering mode (Mobileuncle MTK Tools in play store), even it is a MediaTek MT6577 based phone. When I touch this option, the screen blinks and nothing happens.

What I did in my case, was change this two files below (root needed, folder /system/etc – you can use root explorer/built in text editor to change this config files)

file “conf.gps” , delete everything and put this:

NTP_SERVER=0.south-america.pool.ntp.org
NTP_SERVER=1.south-america.pool.ntp.org
NTP_SERVER=2.south-america.pool.ntp.org
NTP_SERVER=3.south-america.pool.ntp.org
NTP_SERVER=0.br.pool.ntp.org
NTP_SERVER=1.br.pool.ntp.org
NTP_SERVER=2.br.pool.ntp.org
NTP_SERVER=3.br.pool.ntp.org
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
SUPL_HOST=supl.google.com
SUPL_PORT=7276
SUPL_TLS_HOST=lbs.geo.t-mobile.com
SUPL_TLS_CERT=/etc/SuplRootCert
INTERMEDIATE_POS=1
ACCURACY_THRES=2500
DEFAULT_AGPS_ENABLE=TRUE
DEFAULT_USER_PLANE=FALSE

You can change the NTP servers to your country settings (go to http://www.pool.ntp.org/ and find it.

file “epo_conf.xml” – at the end of file, change to “yes”:

–>

Make sure the permissions for the two files (gps.conf and epo_conf.xml) is RW-R–R–, if it is not, change it. Reboot phone.

Go to play store and install app “GPS Status & Toolbox”, test the GPS outdoors. I hope it works to you, in my Razr D3, now, it takes less than 60 seconds to synchronize to satellites, before, could take more than 10 minutes.

I followed the instructions that work perfectly with the network on, but there’s no way the offline gps does not take the satellites. Do you have any idea?
Thank you very much.

well, i figured out that i needed to wait longer for the green dots, thx for your tutorial.
though i just tested it with tomtom and copilot (europe) and its not satisfying cause its inaccurate. (not working properly at all)
i dont have the option for a stable internet connection.

do you have any hints left?

Vincent on July 20, 2013 at 1:55 am.

Hello,

did you update the EPO Assistance? i mean download epo, then test the phone outside? does it lock in to your location with the aid of wifi?

How where you able to test the gps of your phone? did you use it outside, if you were able to connect via wifi, it might be that the phone has trouble finding satallite signals in your area.
could you test it in the best possible condition, clear skies, away from buildings?

vince

Other than that, the phones are pretty good.

Hi

Thanks for the useful info
I’ve managed to get GPS data but it is not accurate
I see myself many times off the main road although I’m on it.
May be it has something to do with the signal strength?
Any way to see my current signal strength? and maybe increase it?

Thanks

Hello Shlomi,

Unfortunately its a hard mod, so basically your going to open your phone and solder it to the gps antenna (RISKY AND COULD DAMAGE OTHER COMPONENTS). Somebody made a mod (i think it was french) on his UMI X1

If your phone is mtk procesor, it will never work, unless you use 3g(data conection).

Reply

Vincent on September 13, 2013 at 5:43 am.

Hello Bacha,

It does work for MTK phones, previous generation like the MT6577 (sophone i5) wherein the gps works fine. Indeed some phones have weaker gps antenna, some are not optimize for GPS and therefore needs updating or flashing and others get a lock but takes too long just like the HDC Galaxy S3 EX. Thus it is usually a case to case basis.

Bacha on September 13, 2013 at 1:03 pm.

I have had mtk6577 and 89, HDC phones, none of them had worked.

idk if they work on phones like gophones, jiayu and all that, but at least in HDC phones they won’t work

(i have flashed, reseted, etc etc)

Vincent on September 13, 2013 at 3:25 pm.

Hello bacha,

From experience and information from other users, HDC usually releases quite a lot of phones compared to other manufacturers. they are usually cheaper, the my first phone, the HDC Galaxy S3 EX (dual core version) has a very weak gps antenna, similar to UMI X1 (dual core also), i was able to get a lock but it took me 7 to 8 minutes and i have to be outdoors. Wifi or data support, no problem, the stock rom (i cannot get a lock or even google maps dont work). So, i change to a custom firmware and it worked but it takes 10 minutes which is forever and is also not very accurate to say the least. The Sophone i5 (which my sister has) it is an iphone clone, GPS was quick, even better than some original phones from samsung. lock within 1 to 2 minutes, it was also accurate. Thus, it usually depends on the manufacture. HDC is usually plague by gps problems, as with umi and star. Other phones that work fine include zopo, zte, lenovo, meizu, oppo, xiaomi, they have the same quality, although a bit more expensive than the other ones.
i will be making an extensive review of the iocean x7 Turbo version next week when it arrives.
hehe, this is quite long, thanks and i hope this helps

Best Regards,
Vince

Bacha on September 13, 2013 at 3:45 pm.

Thanks Vincent, i’ll check some phones u mention, then i will talk about those brands !.

Bacha on September 13, 2013 at 4:54 pm.

I have read several pages and youtube videos, and all says that gps won’t work, I think is a general problem in ALL MTK PHONES, next week 3 diferent MTK model arrive to my house, i’ll be posting if there is one that really work, if they don’t work, there would be 6 phones that i have bought and the GPS doesn’t work.
