Restoring app (QuickGPS) from Windows directory?

[Boinng]

During the hunt for a fix for the hopeless GPS in the new 6.1 Rom, I stupidly uninstalled QuickGPS, and now - since I've found no other fix and it's patently something that HTC need to sort out - I'd like to reinstall it, in the dim hope it will be useful again some day.

Although there are various QuickGPS cab files floating around, none of the ones I've found are the peculiar 6.1 version (marked "Version 1.0" but copyright 2008, and with a higher build number starting 220.821). The only ones I've managed to download from anywhere are the original versions from 6.0 Roms, which - while they don't work any worse than the newer one - aren't any better either, and may well prove to have some other problem under 6.1. They must have changed it for a reason right?

Now it turns out, from reading up elsewhere, that my QuickGPS is still there on the device, sort of - if I set File Explorer to "show all files" and browse the \Windows folder, QuickGPS.exe is there, and it's the right version - I can even run it and download data. But it's no longer an installed program, so doesn't run automatically, and (since I deleted it's registry entries before) it's not setup properly there either.

Without a CAB to re-install it properly, is there any way I can persuade my phone to accept it back as an installed application, short of a hard reset? Or, does anyone perchance have it as a CAB?

I do not know why people are using the newest QuickGPS. THe only difference the program has is cosmetic. THe only purpose of QuickGPS is to have your phone read the GPS signal quick if you are using AGPS. Hence why it needs to connect to the internet to work.

True GPS signal is one from the GPS receiver built into the phone. First are you using AGPS??? Secondly if not, I do not see the reason for having it on your phone unless your using AGPS.

Ok, firstly, there is no "cosmetic" difference between the different builds of QuickGPS, so I'm kind of doubting your authority there straight from the off. The lack of any obvious difference is exactly what makes me think there probably is a more significant change under the hood. Secondly I was using the latest QuickGPS because that's what came with the latest 6.1 ROM update (which I'm also using). It wasn't some crazy whim of mine; HTC put it there, presumably for a reason.

You're confusing QuickGPS with A-GPS; in the context of the Tytn II they're two different things. QuickGPS is an app which downloads ephemeris data when online (during Activesync sessions etc) for use later offline. In theory, the GPS should be able to use this data later to speed up fixes, since it already has the empheris data and doesn't need to download this from the satellite. At the point at which you're out and about using the GPS, no internet connection is needed, because QuickGPS has already stored the data locally. This worked well (for me at least) on the old 6.0 ROM, but is sadly broken in the 6.1 update (and no, reverting to the original QuickGPS doesn't fix it - the problem is most likely in the radio).

A-GPS is different, it's using live data from the network to help triangulate position and speed up the fix - meaning a live connection is needed whenever you use GPS. It's only active if you have it switched on in the registry, and AFAIK only certain networks support it - on HTC branded devices it's always switched off by default.

Is there really no way to reinstall an app, when all the files are apparently just sitting there?

in the first place.....how did you install the app? did you lose the cab file that you used to install it?

secondly.......how did you uninstall it, but not manage to remove the file

The only answer i know will work for sure is a hard reset. (Not the answer you were after I'm sure).

After messing with various quickgps cabs trying to fix this problem i managed to stop my gps switching on at all. (Didn't go near the Windows Intermediate Driver settings).

The only positive is it gave me the opportunity to try a new 6.1 rom (Dutty's Diamond) and i'm really happy with the rom but sadly we still have the quickgps issue.

For a test i compared to a friends Artemis and after a Quickgps update his tomtom had all the sats in view within a few seconds. My posh Vario 3 didn't have anything. :(

QuickGPS gets installed automatically after a hard reset - it's in ROM as one of HTC's customisations. The surprising thing is that I was able to uninstall it, through the remove programs screen.

The files are still there because, apparently, they never left - they just got hidden. "Show all files" in explorer reveals them though. What isn't there is an installation cab - just the app files themselves, doing nothing.

That said, since I ran one of those files it now *is* doing something, happilly - after I messed with the options it re-established it's registry settings and is now running again as a service in the background, surviving soft resets. I manually recreated the shortcut in "programs" and basically all is well again, although since the option to uninstall hasn't returned it presumably still considers itself uninstalled somehow...

About the cosmetic difference I was referring to the QuickGPS in the newest DIamond Roms that are being ported over. I appologize for not reading your first post more clearly. Sorry about that
