we could simply use "Sqlite Editor" in Android OS, and we dont need PC at all

Nice guide!

Please add to the OP that using this method, the user disables A-GPS functionality, which means GPS lock will be slower.

Quote:

What is A-GPS?

GPS operation uses radio signals from satellites alone.
A-GPS additionally uses network resources to locate and use the satellites in poor signal conditions.
In very poor signal conditions, for example in a city, these signals may suffer multipath propagation where signals bounce off buildings, or be weakened by passing through atmospheric conditions, walls or tree cover. When first turned on in these conditions, some standalone GPS navigation devices may not be able to work out a position due to the fragmentary signal, rendering them unable to function until a clear signal can be received continuously for up to 12.5 minutes (the time needed to download the GPS almanac and ephemeris).

An Assisted GPS system can address these problems by using data available from a network.
Assistance falls into two categories:
1. Information used to more quickly acquire satellites
2. Calculation of position by the server using information from the GPS receiver

As an additional benefit, in some A-GPS device implementations, the amount of CPU and programming required for a GPS receiver is reduced by offloading most of the work onto the assistance server.

GPS, is slower on time to first fix. That is why many mobile phones combine A-GPS and other location services including Wi-Fi Positioning System and cell-site triangulation and sometimes a hybrid positioning system.

Yes, i wrote so !
The first fix is a little slower, about 10-15 seconds more, and Agps is totally disabled, but is not a problem, the gps chip work so well, it doesn't need data like other normal car gps

I have a Q. I've got a .58 rom (original SE), rooted.
In you first post you only mention .42 and .62.
Have you tried with a .58 rom?

Cheers

0.58 is not available on my country, but i don't see any reason why it shouldn't work . You have to modify a system file of android, not a Sony one, so should be the same.
Of course if you didn't experience the bug, don't try this guide
but i think 0.58 hasn't a bug fix, like all 4.xxxx builds

I have this bug. I believe all Xperias have this problem. I have been reading the thread on the SE talk forum, about the GPS bug. It was there I read about this fix
I will try it and then report whether it worked or not. It can take a few days, I'm sick atm.

I have tried with the method on 1st post and got a boot loop

---------- Post added at 05:41 PM ---------- Previous post was at 05:17 PM ----------

Ok so there's something wrong with your tuturial.
I have redone the process and when you paste the setting.db and it asks you to replace it, and you say yes, then the file disappears! But no fear, go back to your SD card, copy the file again and paste it again (this time it won't ask you to replace because no file is there!). Then go the permissions and change them accordingly.
Close program, reboot and it's done!

Well my trip only took 15 minutes but it did not go down a single time . In 20 seconds I had GPS lock so it was still pretty for a cold boot (and its rainy weather).
Although there is a minor issue, without the a-gps there is more lag between the map and your real position on the road.
