Polaris GPS problem after upgrade...

[d4rkkn16ht]

I've searched the forum but I can't find any similar problem for Polaris.

I recently upgrade my Polaris into WM6.1 official ROM.
Everything looks fine until a few days ago my Garmin,Google Map & QuickGPS start working improperly.

All of my GPS software can't find any GPS device.
It just blank,no satellite signal at all,even after a few hours.
I've tried many GPS tools to analyze but all useless.

I've tried to recover from my Sprite backups but even the first backup with working GPS state can't solve the problem.

So I decided to Hard Reset.

It worked,but not for long...
The same problem occurs so I try to analyze the cause.

The cause is invalid program behavior :

WM Error Reporting
CE-Star
...and some other software built for older WM


The BIG Question is....why & how?
Why some other older software works why some other not.
Why newer software can also cause this ??
How to solve this problems ??

I hope someone here can help me solve this problem :)

You have problem because old software is not compatible with WM 6.1

I'm sorry to tell you that you did not search well, because all kinds of trouble with 6.1 are described in this thread:

My search keyword is "GPS problem" & I can't find anything related with Polaris...
...and even that thread only mention GPS not work well or slow.
My problem is GPS not working at all after a few days of use & after installing several apps (new & old).
(CE-Star & WM Error Reporting is a new apps)

BTW,it never happen when I use my old ROM which is the official WM6.0 ROM
I've installed many old software (for 2002,2003,WM5) & I never get any problem with my old ROM.

Only about a week I use the new ROM (official WM6.1 ROM) I get this problem (GPS inactive).

one more symptoms is sometimes my GPS LED signal turned on by itself right after soft reset.
That's why I assume it is WM6.1 BUG...

Any other solution...please ?

This is not due to WM 6.1 - it never happens to me.
However, I don't know what is cause of your problem. Are you sure that there is no hardware error?

I'm sure of it.
The GPS is fine if I install nothing except GPS software (garmin & google map).

When I forgot to disable the WM Error Reporting & once it report an error....the GPS stops working.
That's why I disable WM Error Reporting.

So, if there is only Garmin soft & Google maps there is no GPS error?
Then this could be a software conflict.

I'm afraid that you have to do installation of other software you use one by one, on try-untill-it-fails scheme. Start with software which is most important to you... i.e. Total Commander, Skype, S2U2...

How can a software conflict caused a Hardware malfunction...
That's why I call it WM6.1 Bug.
Software (non driver) conflict must not caused hardware malfunction.

I've done that 5 times already (5 times hard reset)...& is going to be 6
I'm tired of doing that.
I can't restore my backup bcoz the problem is persisting.

I hope anyone of you can help me with another solution :)

Hi,

have you tried to look at the data coming from the GPS hardware, for example with the HTC GPS Tool (http://forum.xda-developers.com/showthread.php?t=360477)

You will be able to see better what's happening than using nav or mapping software.

BTW the GPS hardware in my Orbit 2 works *much* more reliably than the same hardware in my Ignito/Diamond and IMO makes the Orbit 2 an all round better machine, I conclude that the problems with the Diamond are due to a poorly implemented antenna.

@Bodisson, have you returned your Polaris to WM6.0? I rashly upgraded to 6.1 and I'm suspicious that it's causing some problems, e.g. with biotouch freezing etc. I'd be interested to discuss :)

As I said on my first post :

.............
I've tried many GPS tools to analyze but all useless.
.............

...and that include HTC GPS Tool, some other GPS tools.
The result is a blank data, not even a weak signal.

Usually when my GPS works,at least it shows weak signal in Garmin (when not in open space & of course no fix).
But when it's "dead" (like just now....6th time already & just Hard reset to make it work again) no signal at all & google map even tell me that I don't have any GPS attached.

O.K. - Then how about GPS Cycle Computer (http://forum.xda-developers.com/showthread.php?t=424423) which can use its own custom internal DLL to bypass the winmo DLL.

I guess if that doesn't work then maybe your internal antenna has come adrift (do you have an external antenna to try) or the hardware is faulty?

EDIT: "I've tried many GPS tools to analyze but all useless" You haven't told us which tools you tried, they aren't useless, you *may* have a hardware fault!

I'll try that...thanx ;)
BTW,i said "it was useless" becoz it can't solve my problem...all stated the same : no GPS signal & even no GPS at all.

about the tools....sorry...my bad...:p
I've tried at least 2 tools & 3 GPS apps.

Tools : HTC GPS Tool & GPS Toggle.
Apps : Garmin XT,Google Maps & Palringo (locator).

About hardware fault...everytime I hard reset it work.
...so I don't think it's hardware fault.

and also Quick GPS always reporting connection error when the GPS stop working.
I've tested the connection & there is no problem with the connection.
I also tried connecting it with a DSL connection & still connection error.

This error never happen when my GPS work.

At last I think I know what cause it & how to prevent it happening.

After some experiments & analysis, I can conclude it that the cause is Registry Bug.
Everytime I Install many new software & didn't give them enough time to load the registry the same problem happened.

To prevent that from happening I install the other software 1 by 1 & give them time to load the registry properly about 30 sec - 3 minutes & the problem is FIXED :)

There is likely no problem when the software I installed did no registry changes (at least according to my experiments).

[Bodisson]

As I wrote in post #6 - software conflict. ;)

BTW, QuickGPS does nothing with GPS hardware - it just updates satelite data. It's error is regarding connectivity to internet!

But, I'm glad that all is working now.

As I mentioned before,the problem only occurred when I install many apps all at once (which i usually did :p )
The registry entries of all apps were queuing on the memory before all can be loaded & that caused the problem (GPS down).

All the apps I mentioned before causing the problem because it did a lot of registry modifications (but I don't know with WM Error Reporting).
As I installed more & more apps with many registry modification, without waiting for the registry to load, the problem occurred.

Now I can install all apps perfectly (1 by 1 with delay about 30 sec - 3 min every installation) ;)

About QuickGPS...
I know that it's only download the GPS data & has no connection with the Hardware.
...but it help me realize that QuickGPS is also accessing registry.
When many new registry queuing to be loaded,QuickGPS can't access the registry properly & prevent it to update the data.

Thanx for replying anyway ;)
