Update verizon PRI and Sprint AGPS

taidan · #1 (**permalink**) 07-22-2008, 05:46 PM

So unless your on sprint, basically your gps sucks. Two things they have is updated PRI and dling from an AGPS server. Is there any way to update the PRI for verizon without bricking? (maybe using a sprint PPST but doing something special to just keep the PRI)

And this is a long shot but do you guys think it is possible to dl GPS data from Sprint AGPS servers? maybe trick it some way?

thanks

you can try an updated prl for verizon and see if that helps. prl files are available here: http://www.corolada.com/prl/

I've been told it's very dangerous to use another carrier's prl file. I finally got locks in seconds this afternoon, after making a couple of changes. First, in the registry I changed the SUPL AGPS/ServerIP value from 95.207.101.126 to 172.25.8.100. With that change I noticed that I picked up more satellites, but still no lock. (I have an extra non-sprint vogue that I've been experimenting with so I was able to compare my xv6900 with the changes to the alltel without the changes). Then I added the files that I've attached in the .zip file to the Windows directory. Once the files are in \Windows, just click on 1_SP_AllowCertificateInstall.cpf and 3_SecurityOff.cpf. With 2_SdkCerts.cab, click on it and it will install itself. Soft reset. After that I had locks instantaneously on the device, whereas with the other that I hadn't made those changes, no locks. These files were posted on ppcgeeks shortly after the alltel upgrade, and worked to make the gps work. Obviously use at your discretion, but I've not had a problem.

If that works you shall be my hero since the GPS on Verizon phones right now is balls.

I'm curious - I'm not a techie and don't understan much of the jargon here. I have Verizon's xv6900 and have just used the kitchen along with most recent Sprint Rom and my xv6900 averages about 6 sat locks. Usually locks in around 30 seconds depending on clearness of sky. Even locks in my in home in certain areas pretty quick. Is this the GPS that sucks for Verizon. Maybe my expectations are lower, but I have always been able to get a lock with none of the registry tweaks you speak of. Are you getting comparable speed and just not happy that it isn't as fast as SPRINT or are you just getting no GPS service. Also I live in LA.

Maybe it has something to do with location, but no, I'm not talking about the situation you have. What is very frustrating is having a device that has gps capacity but not being ablt to get any locks, or it is terribly inconsistent that it makes the gps worthless.

Can you give the full path for hte SUPL AGPS/ServerIP in the reg edit?

Thanks!

this worked on the alltel vogue as well. Where I wasn't getting any locks, now getting between 5-7 in seconds on both the xv6900 and the alltel. Also had changed GPSMode (in HKLM/Software/HTC/SUPL AGPS) from 2 to 4.
