Upgrading Radio

[drowe]

This is a re-post of one I did on PPCGeeks. Haven't received an answer there yet.

I have a Verizon xv6900 that has the 2.31 unlocker on it. I have flashed to other 6.1 ROMs, but am currently running the stock Verizon one. When I flashed back to stock, I let the customizations run (I like the version of Opera that comes with it) and my gps is non-functional. I've fought Valhalla, all the "fixes" that seem to work only for specific users and am wondering if upgrading the radio will fix the GPS. I went back to the stock ROM because the bluetooth works with my Redfly. I would trade that for working gps in a custom ROM.

If I upgrade to the Bell ROM with radio 3.42.50,

1. Will I get the use of the gps back?
2. Will I need a new A-key?
3. Will this lock me into using only custom ROMs?
4. Can I flash back to stock Verizon and will it downgrade the radio and poison the gps again?

Thanks for any help. I've read ImCoKeMaN's threads about downgrading radios and am just a little nervous about messing with the radio rather than just with the ROM.

You should but there has been problems like that with the stock verizon rom. Try to flash the Radio (3.4....or higher) and make sure you have Cokemans Unlocker/Bootloader.
If that doesnt work, refer to this thread http://forum.xda-developers.com/showthread.php?t=462206

Hope you get the issue resolved. Good Luck!

1. Will I get the use of the gps back? Yes
2. Will I need a new A-key? Dont believe so
3. Will this lock me into using only custom ROMs? No
4. Can I flash back to stock Verizon and will it downgrade the radio and poison the gps again? Once you have it fully flashed you can always go back to stock (without downgrading radio) I think it is NOT good to DOWNGRADE the Radio. You dont have to change it back to flash to stock.

Thanks for the information! I have searched for weeks and couldn't find that link! One other thing, I'm in W-S, NC! Out of all the people here, who'd have thought a next door neighbor would have the answer!

Glad I was able to help. Seems like quite a few of us are in NC.

No luck.... When I ran the second half of the directions first, no satelites were found. I then tried doing the ppst portion like the directions asked and nothing happens. It kills the phone connection and requires a soft reset to get it back. I backed out of everthing at that point since I'm on call and can't be without the phone.

1. Will I get the use of the gps back?

Negative, letting the customizations run on the stock verizon rom is the culprit, that locked down your gps. You just have to search on how to fix it, I believe you need to change your PRI or your PRL to get gps back.. not positive which but I've seen the fix on here

2. Will I need a new A-key? Nope

3. Will this lock me into using only custom ROMs? Nope

4. Can I flash back to stock Verizon and will it downgrade the radio and poison the gps again?

Yes you can "downgrade" back to your verizon rom and radio as long as it is the verizon wm 6.1 rom because that still has a GPS radio. I have gone from the Bell 3.42.50 radio back to the Verizon 3.37.38 a couple times, as the .38 actually seems to have better reception in the location I am now than the .50

edit: If you do get your GPS working by finding a fix and decide to flash back to the stock verizon rom.....
DO NOT LET THE CUSTOMIZATIONS RUN (soft reset the phone before they start on the first boot)

I went from 3.37.78 to 3.42.50 and saw no difference at all. Didn't seem to hurt anything, but didn't seem to help anything either. YMMV......

[gogodj]

Thanks I updated to 3.42.50, didn't notice any change either

[theoneownz]

I have 3.37.78 and have had alot of dropped calls and missed text messages. I have to upgrade but have been lazy about it.

I have Verizon also and have successfully flash 9 different vouges

-2 (Insurance swaps) with the issue of GPS.
-3 (Friends) with the issue of GPS.

If your stuck and have a question just pm me. Ill be willing to guide you the correct way.

So, is there any way to get a stock Verizon Windows Mobile 6.1 ROM on my Vogue (avoiding poison customizations, etc.) and put on the Bell 3.42.50 radio? I'm using the 3.42.50 radio right now, and it ROCKS, but I'd like to go back to the standard Verizon software load, other than the radio firmware.

In the Kaiser world, there are RUUs that update the radio only. Do these exist for Vogue? This would seem to be the ticket...

Recently tackled this myself, due to the lack of a small SD card, I flashed the Bell ROM which includes radio: 3.42.50. Personally, NFSFAN's 6.5 (also works with his 6.1 build) suits me well, so I RUU'd that over top of the Bell ROM, the bell radio stuck, and both NFSFANs builds works well with that radio.

Official Bell ROM from HTC includes 3.42.50 radio: http://www.htc.com/us/SupportDownload.aspx?p_id=70&cat=2&dl_id=98

****If you want to keep the stock Verizon software (ROM, etc) take a look at this thread http://forum.xda-developers.com/showthread.php?t=415364 You can flash a stock Verizon ROM to your phone, and then, using a mSDcard flash the 3.42.50 radio.

Here is a link to the Official Verizon MR1 ROM
