6/8/09 FIRMWARE UPDATE: Verizon GPS Unlocked

[n8mack33]

I was wondering if this would have anything to do with messing up my data connection? I am using Scott's 3rd rom and the gps fix and everything was fine until I roadtripped to San Diego and I am not getting EVDO down here at all (eventhough I am in spots where I know I should be getting EVDO). EVDO was working in Nor Cal. Any ideas? I could really use help since ICS is unusable ATM. Thanks.

I see on your ROM screen caps that you show greater than 200MB of ram, which indicates you are using a Sprint TP on VZW. That could be the difference, that allows you to use aGPS.

Could tht be the case? Because I have never got a lock like that with the TP. I was getting that with a few ROMs when I had the Vogue.

Batter is mute issue like you guessed.

No reason not to. I have it and can tell you that I am alot more consistant locking than what most state running my ROM. I have yet to do the CAB that GC posted though. Im going to try that now and see if it gets better. I tried it on his ROM and the results were the same as my ROM. Anywhere from 15 to 75 seconds. Thats the exact same speed VZ Nav uses.

I'm getting locks pretty quickly. I think the data connection status is important. I use VZW wireless sync & when I set it to push every 30 minutes vs. constant sync the data connection turns itself off intermittently.

Not an empirical test but when I set data connection to always on I get a pretty quick lock on GPS even after a soft-reset or if I haven't used GPS for hours....again I haven't fully tested this.

This may be why some users lock quickly & other don't?

GC - does AGPS force a data connection when it needs it?

Okay...I'm a noob & a COMPLETE moron... and this stuff is quite a learning curve... I really got to learn how to read.

I did the AGPS hack but I forgot to uncheck & re-check all the little gray squares. i.e. I have not been using AGPS all this time!!

So this thing locks without AGPS in 30 seconds outdoors & bout a minute - 90 seconds indoors - yes that's right indoors - no agps. This shows me HTC has an excellent GPS radio in this beast.


So I did it right now - from soft reset - 8-12 seconds to lock. Tested three times after 3 soft resets.

My hats off to E-Rice, Scrosler, Bored & GC - you guys are freakin' geniuses.

One thing I'm curious about is what happens if say, your phone is off...or at least your GPS is off and you move to a location that's maybe 5-10+ miles from your previous location. Do you get a quick lock then?

I think, at least with my standalone car GPS that I always got a pretty quick lock if I was in the same place as the last time I turned it on and not that much time had p*****.

I wonder if GPS units use the last know position to help it try to find where the satellites are.

So a nice test would be to turn off the GPS, go to another location and then see how fast you get a lock.

Johnny, I REALLY hate to admit this...But yes I did the same thing as you..After reading this post I figured I would just try and see if it made a difference..And sure enough it did..I guess I also need to read a little better and follow directions! I'm a guy what can I can?! lol I just got a lock inside in less than 30 seconds!

Well, I can't seem to figure out why my gps isn't working!

I started out with scrosler's ROM and attempted to do this fix but it didn't work... I didn't mess with it too much so I just went over to gc's ROM and decided I would try everything over again.. here's what I did:

1) ran bored's cab
2) executed ppst.exe
3) did QPST hacks (Display and aGps tab)
4) installed gc's agps cab (which is apparently not needed after using carrier cab)
5) ensured location was set to ON

still no locks... google times out

any words of wisdom?

same here! i did the fix right and everything. cannot get a fix on Live or Google or HTC GPS software...
at one point it took almost 3 minutes and i got a lock, but then it never worked again.

using VZW stock rom.

i've hard reset 3 times and each time *228 first then installing the necessary files...

Install PPST 1.46 and go thru the normal steps with PPST.exe. Then once you are rebooted apply the fix again. During that time go ahead and attempt to remove the old copy when you are prompted to. It will fail but don't worry. Continue on with the new install. Don't program via *228. The PRL within the fix is the newest one that can be aquired via *228. Please follow these exact directions to see if you get the same results I do when I get issues. Just to clearify, I get issues because I'm still messing with this fix for an update. Your's very well may be for an intirely different reason.

Once you've done all of that. Use HTC GPS Tool to verify the GPS is working. I've had various issues connecting when I continously mess. My fail safe is to always revert and then reapply the fix.

By the way, a hard reset isn't necessary. Mine will work again everytime without going thru that.

well, the hard reset did help. i did the *228 and the verizon network appeared on the today screen b/c it was empty before the activation (weird, but it worked). i did everything again step by step and after restarting and i went outside for 3 minutes, got a gps lock (FINNALLLY!!) and now everything seems to work indoors and outdoors. the initial lock still takes under a minute.

i also discovered a way to tether my laptop to the phone and use the TP as a modem wherever i go w/o the additional $15 a month fee....woohoo!
