That's exactly what you want. You've put it into the mode it needs to be in. Now install the drivers and open up QPST.

Well....I'm ashamed to admit it but I bricked my Pre shortly after doing this mod. Was messing around with the CPU Scalers.

Got it into USB mode, ran WebOS Doctor, upgraded back to 1.2.1, and checked my changes. They stuck, so I'd say from first hand experience that you're good to go.

That's not to say that Palm can't change these from within the OS. You can change your SCI, for instance, so it's possible that a future update could reset them.

Now the command "mpt 0d" is shutting the novacom.
As a result the data port is dead on the phone.

I can make calls , but no internet.
I did disable and enable dev mode just to see if there is anything that gets flushed out.
Nope.

I did noticed the novacom module die in the device manager of my windows after the "mpt 0d" command.

I have to tell you , I have preware install virtual keyboard.

Apart from Preware and Filecoaster the phone has no hacks ( Tethering , LED glow .... etc).

You're where you need to be, and sounds like you've even installed the drivers. Launch QPST and add the comm ports.

[gbp]

Yup I did install the drivers , but I don't see a SURF6800-65 port.
That is exactly my problem.
I am stuck right there.
I am using QTSP 2.7 version 264.

[Ebag333]

Did you add the ports?

A screenshot of what you see in QPST may help.

[gbp]

okay finally reinstalled the QTSP .
(I have to uninstall first).

Sweet , just did the changes.
Soft reset is in progress.

[Ebag333]

So did it work?

[gbp]

Yup, it did , thanks.

As you said , we need a standalone app to test the GPS with airplane mode on.

No you don't. Go into dialer and dial ##GPS#, you can see it refresh without any cell service. I didn't try it in airplane before the tweak though...

Besides, we already have standalone GPS apps like findMycar and others.

Does this mean that someone like TomTom can write a webOS version of their navigation softare, have the map data (which can be a couple gigs) stored on the /media/interal/ drive (USB drive) and you'll be able to use TomTom's software in, for example, Europe, where you have no CDMA signal (and in some situations, no WIFI)??

You think Palm and Sprint will allow this sort of thing for Sprint customers like me who travel to europe and at least want GPS navigation?

I have no doubt it'd be allowed. The question is whether TomTom or Garmin or any of those companies would bother with it. Let's face it, with the free Sprint Navigation on the device, there aren't going to be too many people willing to pay for a GPS program. That, combined with the much lower install base for now, means that it probably wouldn't be all that profitable for them. Maybe when GSM webOS devices get released you'll get your wish though.

You could say this about the standalone GPS devices too. How many people buy the software opposed to getting a hardware unit? I don't have numbers, but I'd imagine it'd be a lot. As long as there's a market, and all other things being equal, there's a decent chance this would happen.

So is it even possible to brick your phone even while using QPST to mess with things? I mean, worst case it sounds like all you will have to do is run WebOSDoctor and you can get your phone up and running. Is this correct? So far I have not seen one case of someone truly bricking their phone.

Yes, you can. Just because WebOS (and the Doctor) CAN make changes to things QPST controls, doesn't mean it DOES. If you overwrite a setting that WebOSDoctor doesn't mess with, you could be screwed.

I have not had good luck with this tweak so far. I consistently receive "Current location cannot be found" message when I try to launch a map in Sprint Nav. It fails to acquire my location more often than not. When it does acquire the satellite, it is quick. This happens at many locations. I'm thinking about removing the tweak.

WebOSDoctor does not effect the settings done by QPST currently (at least not that I've seen).

Most of the QPST settings can be fixed by re-provisioning your phone, but not all of them can.

webOS can change settings traditionally only changed by QPST (such as the SCI), but many of the settings are not touched. I haven't actually tried to brick my phone, mind you, but I'm sure that you could render it inoperable. It's certainly feasible to mess it up enough that webOS works fine, but you cannot make calls out on it.

Try unchecking the AFLT and GPS/AFLT Hybrid modes.

I haven't had any issues with Sprint Nav at all, but I don't use it nearly as often as Google Maps.

Gracias, Jefe.

Great stuff. I'll try this soon.
I'm curious if there's been any changes in battery usage with GPS on.
Just contemplating why Sprint would have chosen not to enable this
in the first place.

Good question.

I would imagine since the acquisition is faster that there should be a slight increase in battery life, but I doubt it's much. (If the GPS only needs to run 5 seconds instead of 30+ seconds to find you, that's gotta save batter life, right? )

I noticed a big jump in battery life, but I did this, adjusted the SCI, and had webOS 2.0 hit all right around the same time. I don't use GPS tons, so I'm pretty sure that wasn't a factor (I'm chalking most of it up to 2.0, with a good portion due to the SCI).
