Possible Fix

After trying OEM ROMS, Cooked ROMS and radios the following got my GPS lock times to winmo 6.0 days.

Please try @ your own risk!

Flashed ROM

RUU_Kaiser_HTC_WWE_3.28.405.0_radio_sign_25.83.40.02_1.65.17.56_Ship

Flashed RADIO

NEON_Radio_Only_1.58.25.17_CustomRUU

GPS Cold Start more than 2 minutes

Install: Schaps_QuickGPS_1_00_17201933_00_WWE.CAB

Download: http://www.badongo.com/file/10273579

Restart Device

Uninstall Quick QPS

Restart Device

Install: HTCQuickGPS 1_00_919717_01.cab

Download: http://www.badongo.com/file/10273599

Restart Device

Now cold lock under 15 seconds and warm under 10 seconds

And yes I tested this configuration for over 2 days (and about 15 soft resets) and the lock times are constant inside my house. When I flash the radio only (without installing QuickGPS) the fast lock times are intermittent and sometimes it takes about 3 minutes for a cold lock.

BTW I was playing with L26 V9 (Hard SPL 3.56/Radio 1.58.25.17) and my GPS lock times were under 30 seconds and consistent so props to Leo.

If you are up to it give it shot and let me know whether the above help your lock times.

I've been using the same radio for about a day now. It works well with gps and has a nice battery life.
[Tilt, TyTN II, MDA Vario III General] sebbes:
So at the end,

would the steps to remove clean the QuickGPS bits be the only necessary steps to get GPS working as fast as with WM6.0, that's something I'll investigate with official ROM + Radio
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
Would that be the one in your sig or the one in the post you're referring to?:confused: Would you say GPS performance is on par with how it was originally under WM 6.0, better or worse than then? What sort of times are you getting to achieve a fix? I'm putting together a letter to HTC management here (their tech support dept rep is claiming I'm the only one who's reported this problem so they won't escalate it) and given how this company performs (or doesn't), I think a ready-made solution offered to them on a plate would stand the most chance of being adopted.
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
Improvement!

Having noticed in another thread that HTC have sneaked out a slightly newer WM 6.1 build (for HTC branded kaisers) which has a newer Radio, I gave it a shot.

As per the subject, there's a definite improvement in GPS (and it seems phone reception also). It's now bearable to use and I got regular hot fixes in about 5 seconds from the GPS turning on but cold fixes are still slow at about 45 sec to 1 min in the same locations. It used to be about 30 sec for a cold fix under WM 6.0, if that. At least I can go back to using Tomtom again though :)
[Tilt, TyTN II, MDA Vario III General] Foxhunter123:
Don't know if it has already been written but a solution that seems to work is to turn off assisted GPS in Kaiser Tweak...
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
I've never had this installed in the first place (its a HTC original device not an OEM/Carrier provided one).
[Tilt, TyTN II, MDA Vario III General] Boinng:
Hallelulah!

Great minds think alike, I saw the same mention of that new radio and tried it myself, using the radio only upgrade helpfully posted here (http://xdaforums.com/showpost.php?p=2376592&postcount=13 - you need HardSPL installed first to do this, but it has the massive benefit of leaving your current ROM, applications and data all in place with no need of a hard reset).

A few soft resets later and I'm seeing a marked improvement, walking down the street I can get a cold fix in 1-2 minutes, as opposed to the 10 it was routinely taking before, and I can even get a fix in a minute or two sat at my desk (top floor, big windows, but it still foxed the previous radio completely).

At a pinch the old 6.0 rom/radio was still a little better, but this will most certainly do :)
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
Even easier if it's a HTC standard device, the latest ROM from their website (a single exe file inside a zip archive with a pdf manual) can be run without a problem over the top of the previous WM 6.1 upgrade a few weeks ago. Of course if hardSPL has been installed and things have been modified I imagine it'd refuse to run. While it's a definite improvement, it's clearly not as good as they are capable of with regards to GPS - we both agree on that so I think it's important to keep the pressure on HTC to come up with a solution. I expect upgrades to make some (or all) functions better on a device. I do not expect any to be worse. It was clearly the driver in the radio code all along that was causing the problem for those who doubted this was the case and got sidetracked with Quickgps :p
[Tilt, TyTN II, MDA Vario III General] Boinng:
So running the official update just replaced the radio, without overwriting the rest of the ROM and losing your data? If I'd known that, I'd have used it myself - I previously had the HTC SPL installed anyway so my device was "HTC standard" as far as any update was concerned.

I went the non-standard radio only route simply because I thought I'd lose my data otherwise.

Actually with hardSPL any update will run :) It's purpose is to override the security of the standard HTC SPL which prevents any non-standard update (such as an unnofficial radio extract).

I'd still say that was a slightly simplistic view - we don't know anything about these drivers, or what exactly has changed in the radio - just like we still don't know why the old radio worked perfectly for some people, and not for us. You're now dismissing QuickGPS as a factor, but how do we know this new radio hasn't merely restored some missing interface between the data collected by QuickGPS, and the GPS itself? The simple answer is, we don't! I'm not even convinced the QuickGPS data is being used even now, it may simply be that the radio performance is improved enough to compensate.
[Tilt, TyTN II, MDA Vario III General] Farsquidge:
OK, done Boston MA, LA Calif, SF Calif, Las Vegas and flying out tomoz to UK.

With the latest HTC WM 6.1 my phone has been totally ****!! here in the US... I have to dial people at least twice to get a connection, GPS takes an Fín AGE to get a WARM lock (forget cold, I had to leave it on the windowsill for 45 mins!) and for some reason, Activesync causes freezes to the phone completely, text input and sometimes total lock-up by Activesync. Not only that, when I start having input problems such as typing errors and touch screen problems, when I check the previously shut down Activesync, it has MYSTERIOUSLY restarted!!!

What is going on with the US network??? MS and Homeland security auto checks on phones???

Will check UK next week folks!! :o:o:o

BTW, as stated before.. works totally fine in UAE!!!
[Tilt, TyTN II, MDA Vario III General] Boinng:
Obviously since mine is a Vodafone branded unit (originally) I needed HardSPL back in October just to get on the original HTC ROM, and my warranty has been void ever since! I actually had to replace the original version of HardSPL with the new HTC SPL from the 6.1 ROM to get 6.1 working properly, since it had some incompatibilty (resulting in lots of freezing) but since then a new HardSPL has been developed based on that same new HTC version, and that's what I'm using now. The ability to just flash radios without the full blown ROM is a godsend, since I'm completely happy with the existing 6.1 ROM aside from the the GPS issue, and pretty much have my phone and all my apps just how I want them. I'm also sick to death of having to re-set everything up again, after going through a cycle of hard-resets with that 6.1 SPL problem.

I guess at the end of the day all this hunting for the GPS issue is guesswork, whether we call it a driver issue or not, only HTC really know the answers. I still have a hunch that something's broken with QuickGPS - not necessarily the software itself, but the relationship between the data it collects and the GPS itself - but I don't know that for definite, and I can't tell if it's still the case now or not - all I know is it's performing consistently better for me now in all my tests, so it's a thumbs up from me. There may still be more improvement to be had, but given how well the phone is performing as a whole now, I might just retire at this point, take my chips and leave. As a Vodafone customer (with no warranty anyway) HTC aren't ever going to listen to me anyway :)
[Tilt, TyTN II, MDA Vario III General] cool_scorpion:
So what is this new rom version

Hi - what is the version of this new rom ? can u post the figures ? On the UAE site, I got this one posted recently: RUU_Kaiser_HTC_WWE_3.28.405.0_radio_sign_25.83.40.02_1.65.17.56_Ship.exe
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
Just the Radio has changed from a few weeks ago

The most recent version from the HTC eClub here in the UK is RUU_Kaiser_HTC_WWE_3.28.405.0_radio_sign_25.83.40.02_1.65.17.56_Ship.zip but a few weeks ago when they first released a WM 6.1 update it was RUU_Kaiser_HTC_WWE_3.28.405.0_radio_sign_25.83.40.02_1.65.16.25_Ship.zip ie only the Radio has changed and the ROM stays the same. When I downloaded the latest file, that was the only one I saw there so I get the impression they realised the earlier version had a problem and replaced it. I just wish they'd owned up to it and sent out another email advising of the updated update rather than sneaking it through!

I also wish their tech support people were more informed because I complained to one of them about GPS functionality (or lack of) running the earlier radio version and this was after they'd released the update - he never asked whether I'd installed the very latest updated update and it does make a difference.
[Tilt, TyTN II, MDA Vario III General] pjwilkin:
I think this needs to be uploaded to the FAQ and FTP site as they currently have only the 1.65.16.25 version of this ROM

Some of unfortunate re-badged phone people dont have direct access to the HTC website to download this (I tried the usual registering tweaks and it think I have french/italian .. but not English phone)

I gave up on t-mobile releasing it ages ago .. after all they have to relese the Vario IV soon
[Tilt, TyTN II, MDA Vario III General] Foxhunter123:
Why those xxx!!!!!XXXX!!!!! HTC!!!!!

You're absolutely right!

My radio from the first 6.1 update is:1.65.16.25 but the "new" from the exact same day as the one I got is: 1.65.17.56.

Come to think of it this might be the famous drop that makes the cup run over!!!

HTC just has the worst customerservice ever! If it hadn't been from this nice site I don't dare think of all those problems I would've had to put up with!

Just one question now...

If I take a backup with Sprite of my 6.1 device - install the "new" 6.1 update will I then be able to restore my backup without losing the new radioversion?

(By the way is there a way to just install the new radioversion without erasing everything...?)
[Tilt, TyTN II, MDA Vario III General] invasion13:
hi,

i did again the french htc rom official wm 6.1 upgrade(with radio 1.65.17.56)

ps: they didnt amend the released date ! just changed the radio version without any notice for those who previously downloaded the 6.1 rom, that the radio version had changed!

i did first a backup with sprite(not the L.E, i had upgraded to the full 6.2 one)

and i had been able to retore all my infos(except i hadnt been able to tick the "database" restore with a the same time some settings(where you find the categories you set or your pim soft(i use PI 8.x) ) i chose the last one because database(i think) they could be restored with an Outlook synchro(contacts and appointements).

ps2: you could make a "pimbackup"(with that freeware) of them prior to the restore in order to retrieve them and avoid a "long" synchro .

No feedback yet for my new radio version.(did last night)

regards
[Tilt, TyTN II, MDA Vario III General] Karolis:
Woohoo! Using radio 1.65.17.56 solved the GPS problem! QuickGPS data does not seem to be used anyway, but I get cold fix in under a minute.

Three out of three tries, cold start, cloudy skies, different parts of Carlisle, UK.
[Tilt, TyTN II, MDA Vario III General] Farsquidge:
Now in UK and whereas not as bad as USA but still bad cold lock and various hangs in other applications especially messaging. Activesync still starting on its own after shutdown.

Saw the latest posts in this thread about HTC's radio release ****-up and updated ROM.

All smooth and Activesync does not auto-start.

Methinks someone had forgotton to replace a TEST radio rom with the final public release version at HTC and hoped to slip it out later without his boss knowing. :rolleyes:
[Tilt, TyTN II, MDA Vario III General] massie:
I confirm the bug, also using 1.65.17.56 or other radio or other quick gps programs.

Any solution now?
[Tilt, TyTN II, MDA Vario III General] mikegadd:
6.1 GPS

I have now installed the official orange 6.1 rom update and matched to hard spl 3.28 as recomended on this forum, GPS lock is quick but does vary from program to program,

McGuider is the fastest.

TomTom faster than TomTom 6
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
Time to hurry up and wait but report it to HTC or your hardware provider

I'm using this Radio as well and I understand your concerns. I was at HTCs UK Technical base in Milton Keynes last Friday and was advised to keep an eye on HTC e-Club. It was also suggested to me that I manually update QuickGPS at least every 3 days as the latest data stored here helps somewhat to get a quicker fix. Ultimately I believe the solution will lie with a new Radio version but while the person I spoke with wouldn't acknowledge a QuickGPS fault, there may be some changes with this program as well. The staff there were very polite, friendly and keen to be helpful - quite a different feeling to their Bournemouth Call Centre in my experience :)
[Tilt, TyTN II, MDA Vario III General] massie:
I have the same radio.

I hope they fix it. A new radio ?

But it seem the gps doesn't read the data. QuickGPS stores a file named xtra.bin (38 kb) in /windows and /temp. In the registry there is the correct area code. I update the file every day ...

Why ? Do you think there is something wrong in the xtra.bin file ?
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
They clearly know about it. That could go a long way towards fixing the long cold fix times and unstable signal reception. They need to get their best people onto it though (or contract a team who do know what they're doing from outside the company to come up with a solution). There have been quite a few radio versions since WM 6.1 for the TyTN II came out and so far nothing comes close to offering the same level of GPS performance as my device under WM 6.0 had. An 'update' which breaks a very important area of functionality is a very poor reflection on the company that releases it, almost as scandalous as not including graphics drivers which properly utilise the available, ready-to-go graphics hardware :mad:

Well it seems to me that a recommendation to download the updates every three days minimum when the QuickGPS design says they should last 7 days max indicates a problem somewhere. Even a bug within QuickGPS wouldn't account for things like the wild signal reception fluctuations that I'm getting even when stationary and the very laggy performance when starting off (it takes much longer than when originally supplied to recognise the device has started moving for example). So irrespective of whether QuickGPS is broken or not using the data properly/at all (or whether the data itself is correct), the Radio code which includes GPS hardware related driver functionality will be the most important part to fix.

I read somewhere else at XDA Dev that a different file about 47kb should be automatically downloaded and to be honest I'm more interested in what they can come up with for a Radio fix for the above reasons. Even the best QuickGPS functioning in the world won't solve the above problems. Perhaps someone who understands more about QuickGPS can comment on that part.
[Tilt, TyTN II, MDA Vario III General] massie:
I try it (downloaded with another program), about 50 kb. Then you have to change the name, but no result, so it doesn't work.

Thanks

I had the same, very slow, GPS lock on my XDA Stellar after upgrading to the O2 stock WM6.1 ROM. TomTom7 would easily take 2 mins to get a lock from a cold start.

I had installed KaiserTweak and used the same settings I used previously on WM6.0 which included enabling Assisted GPS.

I've since disabled Assisted GPS and soft reset, and now my cold start GPS lock is approx 10-15 seconds...
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
Are you in the UK and what radio and SPL comes with the stock O2 XDA Stellar WM 6.1 ROM? How stable are your Tomtom reception bars? How much lag is there between starting off moving and Tomtom registering movement/speed? These are all issues I'm having problems with now (as well as long satellite lock times).
[Tilt, TyTN II, MDA Vario III General] p.dixon0:
Hi there!

I actually timed the lock as I left work today - 8 seconds from it switching the GPS on! I'd used it this morning so I suppose that classes as a warm start.

My system info is:

ROM version: 3.29.206.0 WWE

ROM date: 05/09/08

Radio version: 1.65.16.25

Protocol version: 25.83.40.02H

I hope that helps!
[Tilt, TyTN II, MDA Vario III General] Foxhunter123:
Hmm I was just wondering... When you say that you turn on your GPS - how do you do that? is it 8 secs from when you press the TomTom button in HTC Home or what program do you use...? ;-)
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
It takes my HTC supplied Tomtom 6.032 Navigator about 19 seconds from tapping its icon (from the start menu, I've disabled it from showing in HTC Home) until it starts waiting for a GPS lock so that 8 seconds must be the time spent "Waiting for a valid GPS signal" if it's for the same software and Western Europe map. I consider that an acceptable point to start timing things because other factors will influence how quickly the software will get to the stage where it initialises the GPS hardware.

Certainly differs considerably to my experience with that radio version on my TyTN II here in the UK. No word on the other problems that I've mentioned such as very laggy performance with movement/speed only being registered well after moving off and wild fluctuations of the signal reception bars even when stationary under a clear sky. These weren't problems at all under WM 6.0.
[Tilt, TyTN II, MDA Vario III General] p.dixon0:
Hi guys

Yes, that's correct, the 8 secs is from TomTom waiting for a valid GPS signal.

Everytime I've ran it since disabling Assisted GPS in Kaiser Tweak, it's started this quickly. Even if the GPS hasn't been used since a soft reset, so it's not just warm startup's that are affected.

I'm using the UK and Ireland Map (as that had the latest version number)and I usually get full 5 bar reception in the car. My car is fairly old so doesn't have any fancy stuff on the windscreen like heating / rain sensing / UV protection which can dull the reception. I'm using TomTom 7.450 as extracted by one of the guys on XDA-Developers (thanks!). TT7 has GPS configuration that allows selection of internal GPS over the normal NMEA selection that I had to use on TT6. Having said that, it makes no difference if I select internal GPS or the NMEA one. I must just be very lucky?

The display seems to move fine too, certainly no slower than TT6 running on the old O2 WM6 ROM. To be honest, TT has always ran quite smoothly for me on my Kaiser, no slower than on my old XDA Mini S (Wizard).

I try to run as little as possible in the background on my phone, I use Pocket Mechanic to defrag my memory card and SKTools to free RAM. I have also installed the HTC GPS tool that can be found on XDA-Developers (I can't remember who extracted it, but thanks!) but this seems to just be a testing tool rather than for any configuration purposes.

I'll try and take a video from my Wizard of the GPS lock time and show how it runs if that's any help to you?
[Tilt, TyTN II, MDA Vario III General] p.dixon0:
OK, so I've just tested TT7 again on my way to the local supermarket this morning.

After a cold start (after soft reset) - 30 secs to GPS lock

Starting up after coming out of the supermarket - 8 secs to GPS lock

It appears to register movement of the car quite quickly, just less than a second after actually moving off - about the same as TT6 on my old Wizard with bluetooth GPS, and same as my Kaiser with TT6.

I get between 4 and 5 bars on the GPS signal strength most of the time too.

I do notice that it can lag a little while going around roundabouts, junctions etc. but this is the same behavior I've always experienced with TomTom, even dedicated TomTom Sat Navs.
[Tilt, TyTN II, MDA Vario III General] sys50000:
Best GPS fix for me

I also was not satisfied with the GPS performance of the Kaiser's original WM 6.1 roms. Long fix times. Sometimes 5 minutes and never inside the house. So, after reading this thread I also decided to experiment a bit and the best combination for me is:

ROM: 3.29.404 NLD

Radio: 1.71.09.01

Protocol: 25.75.40.02.eMo

HardSPL: 3.29

I am astound by the difference. Fixes always within a minute. The satelite signals are not necessarilly stronger, but it sometimes has a fix already if GPStest has all satelites still in the red. It is also the first time that I have seen a fix inside the house. A little bit jumpy, but a fix for sure. I also have the impression (I can't know that for sure) that this combination uses the Quickfix data really. Even after a cold start I can see the satelites in red almost immidiately spread over the sky.

I have tested this a couple of days now and I am really satisfied with it. I think that this is how GPS on the Kaiser should be working. An I have (until now) noticed no problems with Wifi, camera, GPRS, or what so ever.

Succes.

'edit'

Used HTC GPS Tool (thanks ashmont) to measure fix times.

Cold start: fix in one minute

Warm start: fix almost instantly

I also tried the registry setting GPSmode on 1, but that did not improve a thing. Instead it looked like the position become inaccurate.
[Tilt, TyTN II, MDA Vario III General] Spartan2x:
Maybe this was already addresses in this thread, but its 12 pages.

The started said he was running a stock 6.1 ROM

Now to my knowledge HTC has not yet released a OFFICIAL FINAL 6.1 Rom.

So if he has a pre-release then perhaps its the fact that its a pre-release rom?

I've been waiting for HTC to come out with a 6.1 update because I'm not very tech savy when it comes to ROM's so I like to see it supported my the maker.(really really want threaded text messages and the new PIE!)
[Tilt, TyTN II, MDA Vario III General] ashmont:
I managed to get an improvement

I installed the radio that several people were praising ie 1.65.17.56 and disabled Assisted GPS. After doing this I managed to get a fix after soft reset in just over a minute. This was done in beautiful UK summer weather (ie overcast) both inside near a window and outside. I can typically get a fix on warm start in a few seconds (outside) or at worst 30 seconds inside if the signal is not very good. I even managed to get a fix while up in the loft with no window in sight (I just couldn't resist trying).

However, I can confirm that that when using HTC GPS Tool, there are initially no satellites displayed when attempting a fix after soft reset. This may mean that QuickGPS data is not being used. Having said that, I have no problem updating emphemeris information with QuickGPS and the xtra.bin file is created in the temp + windows directories each time. Also, I have my location set to GB in the register settings - I am with T-Mobile in London, UK.

However I am happy with the results described above and they seem more or less as good as before I upgraded to WM6.1 (L26 v 12).
