XV6800 Searches Endlessly for Tower with anything but the stock radio ROM
 
SOLVED! SEE MY POST NEAR END OF THREAD!

Hi All,

I have seen other reports of this problem, but never any solutions.
I have an XV6800 that I purchased as a backup phone to my touch pro. When I got the touch pro it felt so flimsy that I really did not think it would last. So I am now confident in it and decided to get out the 6800 and put it on eBay. So I decided to play with it a bit before putting it up for sale.

If I flash any other radio than what is in the Verizon stock ROMS, upon reboot, the phone will perform an endless search for the Verizon towers. I can force it to connect by dialing *22801 which gets me a U.S. Cellular error message. As soon as I hang up I get a Verizon lock and full EVDO signal. From that point forward, the phone works great! It gets GPS locks in under 10 seconds!! If I could figure out this problem I would be 50/50 on considering moving to the 6800 over the TP. Pandora and streaming audio work flawlessly on the 6800 and it feels like a real phone. There is still no VGA Pandora app that actually works properly... And Audio on the TP has a lot of clicks and pops....

So as I have said, I have seen others report about this issue, but never seen a solution or the OP ever come back saying it was resolved. So I bring up the issue again to see if anyone has any unposted insight into this problem.

If you get a us cellular message then likely you dont have a verizon prl on the phone. What number is your prl under device info?

Well,
I have flashed back to stock again to check all the numbers and settings.
Phone works perfectly.
In the stock configuration:
PRL: 51638
PRI: 1.35_002
Radio: 1.30.60
ROM:2.09.605.8
MSID: Area code and phone number
MDN: Area Code and phone number
A Key: Blank

I am now going to unlock, upgrade radio and flash and see what I get..
EDIT:
OK, upgraded Radio and flashed custom ROM:
PRL: 51638
PRI: 2.03_002
Radio: 3.35.04
ROM: 3.08.666.1
MSID: Area code and phone number
MDN: Area Code and phone number
A Key: Blank

So everything is the same but Radio, PRI and ROM...

He had a nongps rom on before the unlock and custom rom. So how does it work now?

Well,

Like I said, it works great after I make the initial *22801 call which connects to a USC tower (I guess) and then gets Verizon as soon as I hang up.. It works great. GPS so fast it spins my head, but it endlessly searches for a Verizon signal after every reboot...

If I just dial *228 while it says no service, I just get repeated dropped call notices...
I do not get it...

Where did you get your custom rom and radio?

I used the PPC kitchen to make the ROM. I used Verizon as the carrier. The radio is the one from this GAMEDIC thread:

No ideas. Did you install the correct carrier cab?

Found the solution!

Code:
You need to do the following:

phone app, dial *22803 or *22802 (whichever one gets you a signal) and hit phone hang-up when you get a signal and it says it's starting to program. Now that you have a signal do the next step.

phone app, dial ##778
select "EDIT" and enter the 000000 unlock code
select "VIEW INFO" and select "M.IP Settings"

Edit MIP_MODE and change to something else, then go back and change it again back to "Mobile IP Preferred".

Do the smae for MIP reg retried, retry timeout and pre-registration timeout.

Change all the values, ok, then change them again back to the original setting.

Settings are: Mob IP Pref, 2 retries, 1750ms retry timeout, 0 pre-reg timeout.

When you're all done save and exit - soft-resets your phone.

You should be good after this.

Good luck!
I just changed the 1750ms timeout to 2000ms and it fixed it....
