GPS Problems: finally the solution

Hi all,

Here I want to tell my experience with HD Desire GPS to help all those who were (like me) desperate.

The way to solve exists ! Read to the end to know how.

I bought my HD Desire in January 2011 (from Euronics in Rome - Italy) and after one week of use the problems began with the GPS.

It did not fix more ... but above all there were more than 1 or 2 visible satellites ... even in open sky, in good conditions, even outside for 30 minutes.

The phone was obviously still immaculate (without root and with the original ROM and RADIO) then I went back to the shop where I bought ... and using GPS-Status the seller has found that actually did not work.

Very kindly he changed my on the flight the phone ... I installed GPS-Status on the new phone just replaced and now everything works fine (fix in less than 10sec and 7 / 8 satellites visible).

I came at home and for 2/3 days it worked wonders but soon it began again with the same GPS problems.

No more fix and at maximum 2/3 satellites visible. :o

Building on the fact that the phone had been replaced and ... GPS Status actually had made a fix in less than 10 seconds ... (When I had replaced) ... I said, Sure ... is certainly a software problem and not an hardware one ... because the phone is a new one.

So I did a factory reset ... reset all settings as the original ... and retried. Nothing. :o

The GPS was dead for the second time in two weeks.

Then, I began a careful search on various forums (both Italian and international).

I've tried everything ... really everything ... but nothing. It does not work ! :mad:

Tried GPS-Status (A-GPS Reset, Download), then fasterfix (it.pool.ntp.org) then I started to change ROM (root, S-Off and ENF S-Off), then I tried all possible Radio and RIL in all combinations. Sometimes happen that the fix was very fast and this gave me the illusion (temporary) of having finally found the solution. However, on time (sometimes even after a few minutes) the problem returns back!

I also tried to clean the contacts of the GPS as shown in this video on youTube(h**p:/*w*wdotyoutubedotcom/watch?v=7qm_z65LA8k).

At the end ... after 4 months of trying all... I sent back in warranty the phone to the HTC service (S-ON and leave to unroot because it was under warranty).

After 10 days of impatient waiting, HTC gave me back the phone and say that the GPS was faulty and had been replaced.

I redid a restore using Titanium Backup Pro ... restoring back all in the exact same conditions I had when the GPS was not working.

Now everything works wonderfully !!! :D:D:D

Im using the original ROM (RUU 2.36.405.8), original Radio (12.54.60.25U_26.09.04.11_M2) and the original Kernel (2.6.35.10-g0956377).

Fix in 10/20 sec (everytime), with at least 7 / 8 satellites (tested for several days now).

Moral of the story ... There are lots of HTC Desire HD phones (probably the first stock) that today are still in the form of stocks and inventories in some shopping malls / shops with the GPS module that is broken !!! (it works for a few days and then no longer works).

The only way is to send back your phone in warranty and ensure that GPS module is replaced (having first restored with all unroot and S-OFF as otherwise the warranty does not apply).

Believe me ... if you have tried everything ... this is the only way!

Now I'm an happy HTC Desire HD owner (with Gingerbread) with a GPS which is a splinter.

Im currently using Navigator, Google Maps, CoPilot and everything works great !

I hope this post may help and comfort those who are desperate and can not run the GPS on the Desire HD. :cool:

Greetings to all.

Andrea.
