Fixing GPS on THL W100 and MTK6589

It's noticed and proved that something is wrong about the GPS on the MTK6589 CPUs in general.
Some ROMs bring the fix for it, but even though if you test your GPS and it gives you a great margin of error (try it on your home! Go outside and test it!), or it takes too long to find a location, you should try this fix.

You'll need to get your phone rooted. (If your phone isn't rooted, follow this tutorial!)
 
- Turn off GPS;
- Download and Install "Root Explorer", "MobileUncle Tools" and "GPS Test" on Google Play Store;
- Open "Root Explorer" and go to the folder "data" or "data/misc";
- Delete file "mtkgps.dat";
- Reboot your phone;
- Get outside!
- Open "MobileUncle Tools";
- Go to "Engineer Mode";
- Go to "Engineer Mode (MTK)";
- Tap "Location", then "Location Based Service";
- Tap "AGPS" and make sure the "AGPS On/Off" is checked;
- Tap "EPO" and make sure the "Enable EPO" is checked;
- Turn on GPS in notification bar;
- Go back and tap "YGPS";
- Wait until get position lock (that will create a new "mtkgps.dat" file);
- Open "GPS Test". Now you should be position lock very quickly.
- You're DONE!

Now you can disable "AGPS" and "EPO" on "MobileUncle Tools", but it's OK if you keep it enabled, it'll lock position quicker.

Installing ClockworkMod Recovery on ThL W100

If you want to install a ROM, backup / restore your phone, you need this. It's ClockworkMod (CWM) Recovery.

To install it, you should do this:
(Again, I'm not responsible for anything that causes damages to your phone. Be sure that the store you bought the phone allows you to do this, without losing warranty.)

- Your phone needs to be rooted (follow this tutorial!);
- Go to Play Store;
- Download and Install "Mobileuncle Tools";
- Download the ClockworkMod Recovery for ThL W100 (mirror #1);
- Rename the file you've downloaded to "recovery.img";
- Move the file to your SD Card;
- Open up Mobileuncle Tools on your phone;
- Select "Recovery Update";
- Choose the file "recovery.img" you've moved to your SD card;
- You're DONE!

Now, your phone has a recovery software.
To access to the recovery, you can choose the option in Mobileuncle Tools "Into Recovery Mode", or if your phone is turned off, press the "Volume up" button with the "On/Off" button together.

It's recommended to each time you made changes to your phone (app install, etc) to keep a backup of your phone, just for safety reasons.
