View Full Version : GPS has died

Hi, I'm hoping someone can help me with this. I've got a UK T-Mobile Vario III.

I've updated my ROM and radio a couple of times and have now discovered that my GPS isn't working. To try to fix this, I've reverted to old ROMs and radios but nothing seems to get the GPS going again. When I load up the GPS Tool and click open, no messages appear in the window at all. I seem to recall that when my GPS was working, messages would appear as soon as I clicked open, even if I was indoors and there was no chance of a signal getting through.

Radios I've tried are: 1.27.12.11 (my original radio), 1.27.12.17 and 1.27.12.32.

So it seems as if the GPS hardware is dead at the moment. Can someone suggest something that I can do to fix this?

Many thanks in advance!

I had a hiccup with the GPS lately. I installed and ran "GPSTest" and it helped sort things out for me

It may take 3-30 minutes to get a HDOP score (as mentioned in the linked post), but at least you'll know your GPS receiver is functioning properly.

Thanks for your replies. Something is definitely wrong as when I run GPS Test, it scans the com ports numerous times and then gives up and tells me the GPS is off. This is so annoying!

Download Franson GPSGate. It will force start the GPS. You can start & end sessions with it at will pretty much. It's also great because it allows you to use many GPS programs at once.

If you can't find it PM me & I'll upload for you. It's free to use in standard mode w/o internet tracking, server connections, etc...

I think there must be something more fundamental wrong. I've installed GPSGate and when I selected "wired or in built GPS", it is unable to find anything. It looks as if I'm going to have to get this repaired unless anyone has any other ideas...

Have you tried running uickgps to give the gps a kick start?

Yes, I've tried QuickGPS but no joy. But because GPSGate can't even detect the hardware, I think it's more of a problem than just not being able to get a fix. It's almost as if the driver or something isn't working.

You may want to check all the registry entries for the GPS. There is a link at the bottom of the Wiki that lays them out for you.

Having done hard resets and also reflashed the ROM, I don't think it can be a registry problem. Pretty sure it must be a hardware problem so it looks as if I'm going to have to get it repaired :-(

Clutching at straws here but could it be down to the fact that I flashed Schapp's WM 6.1 to the phone? I notice that a number of official 6.1 builds require a newer radio so perhaps flashing Schapps changed something else and now (even though I've gone back to 6.0) GPS will only work with one of the newer radios?

Exactly same problem here. I flashed Schapps 6.1 ROM and the GPS is DEAD. I'm thinking about sending it in for service.

Anybody has any ideas?

the only solution i was able to find is to flash to schaps 6.1 rom. the gps now works fine. i guess once u flash to 6.1 ur gps will only work with 6.1....this should be a sticky

Strange that yours works with 6.1 as the other posts all seem to have the same problem with the GPS completely dead. Sounds as if the 6.1 flashes to a part of the ROM that the 6.0 ROMs don't flash to. Surely must be reversible, I'll post a message in the Schaps 6.1 thread. Fingers crossed...!

Omaralt, you da man. Worked perfectly. Even my miomap works this time with schaps 6.1 rom (which it previously didn't). Thanks a lot.

I don't think that this is true - I flashed several WM6.1 roms (and their radios), ending up with Sleuths, but after a while I noticed that it took considerably longer to get a GPS fix.

I returned to Duttys v4 with radio 1..27.12.32 and GPS is working fine and gets a fix as fast as before.

I don't know what the original problem was but in general I found it took longer to get a fix for all WM6.1 roms.

Dutty seems to have a 'team' of great beta testers helping him with his roms and I'm sure that one of them will notice this with his current private beta roms. If so then expect a fix soon.

its not about taking time, when i open up any of the gps programs (gps fix, etc), it doesnt even find the gps! it scans all the com ports, and when it gets to com4 the gps light comes on, but then it scans the other com ports and then tells me no gps found. if i put teh settigns on com4 it'll spend a few mins "looking for gps device" and then say gps off. by upgrading back to 6.1 it works now...

Try a other RADIO ROM

I think it has all to do with the RADIO ROM....

When you downgrade from WM6.1 you must downgrade your radio too to a 1.12 version. Hopefully people are remembering to do this. I've been switching between WM6.0 and WM6.1 a lot lately w/o GPS related issues but I have made a version of WM6.0 that also includes radio flash to do this.

Radio didn't make a difference for me when I downgraded to 6.0. I even tried flashing original AT&T ROM, and the GPS still wouldn't work. The only solution was to flash back to 6.1.

I flashed Schap's 6.1 which didn't require a newer radio and since flashing back to 6.0, I've flashed 12.11, 12.17 and 12.32 to no avail. I also flashed back the HTC shipping ROM which included 12.11 again with no joy. I'll try flashing back 6.1 but I think I first noticed the lack of GPS while using 6.1 and I'm pretty sure I hard reset and it still didn't come back. Perhaps mine went long before - I hadn't tried the GPS in a while.

Hurray! Getting interesting now. I reflashed Schap's 6.1 and the GPS still didn't work. I've now flashed Sleuth's 6.1 which includs the updated radio and the GPS test tool found the GPS immediately. Will now try downgrading to the shipped HTC 6.0 ROM which includes the downgraded radio just to see if the GPS carries on working. All very strange!

Downgrading to the HTC 6.0 + 1.27.12.11 retained the GPS.

So in summary:
If, having upgraded to Schap's 6.1, you lose your GPS, then to get it back, upgrade to Sleuth's 6.1 + radio. You can then downgrade to a 6.0 build but remember you also need to downgrade the radio.

Phew!

hey i finally got it working on dutty's 6.0 roms again. with 6.1 installed, you have to downgrade the radio and then flash the 6.0 rom. gps is working again :)

when i tried to downgrade the rom to 6.0 and then downgrade the radio, the gps didnt work
