Wow, the picture says you're moving at 36 mph 750 meters UNDER sea level: either you live inside a submarine, or MTK GPS is pretty unreliable isn't it?:laugh:

Btw, I tried the procedure on a firend's phone and it worked almost good, it didn't fix at all before but now even if it fixes, loses GPS signal very often, requiring 3 to 15 minutes to have GPS back!
I also tried Engineer functions with test and reset operations, but GPS is always unreliable (1 hour trrip it lost GPS for more than half an hour, making navigation imposssible!)
I think the GPS hardware is really unstable and/or buggy. Any idea?

shantam · Jan 21, 2013

Yeah the hardware is really crap
And i was undersea and was sleeping there...

What's the point of having fast lock when precision suck?
:banghead:
Bumping accuracy threshold from zero to 3000 likely report hyper sonic speed way off sea level

My MTK Phone

Same frustrating GPS issues here.

Hi my MTK phone from china has a file under something like gps-profiles-config. should I delete this and replace it with yours? or do i just paste it along with that one?

Engineer code MKT6577 phone

Hi I found a code for the engineer mode.
Here you can also change the settings for the GPS and test it.
Looks like my GPS is not working because it doesn't show any satelites.

The code is *#*#3646633#*#*

You have to use the phone dialer.

Hope this wil help to find a sollution for the GPS problem.

Jan,

He guy I have a Vowney V5 MT6589 phone, its working pretty well, except my GPS which isn't working, I tried another method but it didn't work, would this guide work for MT6589 phones?

Ezio i95 - mtk6589

Hi guys
I was having issues and tried multiple solutions including the one posted here in this forum. I believe it helped me the most, because it resurrected a non working GPS. However it was still taking 3-5 minutes to get a lock. I came across the following video post and after applying it the lock time is sub one minute... which is great. I thought I'd share it here

Basically the answer is to delete/ rename the mtkgps.dat file from data/misc and then recreate it with the mobile uncle tools .apk which can be got from the play store.
The youtube video makes it easy.

Of course your phone needs to be rooted as well. I can take no responsibility for what happens if you try it. But it's worked for me.
Also as said before, This only worked in conjunction with the fix discussed here in this forum.

The Real GPS Fix

To all members with GPS not getting a fix on the satellites with the V1277 (6577) in a reasonable time I have the answer and it does not require anything but a screw driver and cleaning fluid.
No rooting is required or messing about with the gps config.
Firstly remove the back cover.
There are 4 screws holding the housing remove them and unclip the rear housing .
Take anti static precautions i.e ground yourself.
Use alcohol or another circuit board cleaner and clean all the contacts on both the main body of the phone and housing, Job done.
Before I did this I could not even get a fix on the gps satellites outside , I can get a fix in the living room.
I think the problem lies with the production environment of these phone not being as clean as the major manufacturers dirt and oxides in the air, I use to work as a debug engineer on mobile phones at Motorola, well at least its came in handy.

Probably a fix for most china based phones

This method does not work on my device. I start wondering if there a gps antenna in my phone, maybe they cut cost and remove the antenna :laugh:
