[7/2/10 PRL 51926m/65144m] Verizon VOICE ONLY NETWORK Popup Modified PRL FIX

[CrossroadsTech]

After a month of discussion and testing on the Voice-only network pop-up thread, I'm creating a new thread just for my fix and to make it easy for users to see when I update my modified PRL. For more info and discussion about the problem itself, please visit this thread:

PRL FIX FOR VOICE-ONLY NETWORK POP-UP

Here is my fix for the annoying Voice-Only Network pop up message that plagues Verizon custom ROM users on the HTC Touch Pro 2 when they travel outside or lose Verizon Wireless native (owned and operated) coverage. This PRL is exactly the same as the current Verizon Nationwide Plan PRL except I have disabled the Enhanced Roaming Indicator (ERI) so no "Extended Network" or "Roaming" is displayed. I will keep it updated as new PRLs are released by Verizon.

Enjoy!

51926m - Current VZW PRL
65144m - Current VZW PRL (Hybrid)

Change Log

7/2/10 - Released Modified PRL 65144 (Hybrid PRL)
* Per user request, modified the Hybrid PRL that prefers former Alltel networks over Verizon legacy networks where the Alltel/Verizon network integration is not yet complete.

6/28/10 - Released Modified PRL 51926 (Legacy Verizon).
* Left the "Verizon Wireless" banner on Verizon "Home" systems to see if this will solve the problem with a user reported data application not working and increased compatability with new ROMs auto-provisioning feature.
* Set roaming indicator to off for all non-Verizon systems... no triangle.

2/15/10 - Released Modified PRL 51739 (Legacy Verizon).
* Decided to use legacy PRL instead of Alltel-Hybrid as Alltel networks are almost all completely integrated with Verizon.
* Set roaming triangle to flash when on Extended Network and solid when on Roaming (mostly International) network.

1/8/10 - Initial release of the Modified PRL Fix. Used (Alltel-Hybrid) PRL version 65084. Roaming indicator (triangle) is off for all SIDs.

How to install:

1. Download the current modified PRL and save it to your phones "\My Documents".
2. Dial ##775 and press Talk
3. "Please Enter Unlock Code" displays. Enter 000000 and press OK. (six zeros)
4. Press "Update PRL" and press Menu (right softkey). Select Edit.
5. Press Browse and select the current modified PRL. Press ok (top right).
6. Press Menu and select OK.
7. "Update the items?" displays. Press Yes. Press ok to reboot the phone.

The install is successful when you don't see the "Extended Network" banner on the top of the Today screen anymore when outside the Verizon-owned coverage area. I recommend keeping the modified PRL file on your phone in case you need to reload it back. (See FAQ Question #5 as to why.)

FAQ -- Updated 7/2/10

1. What is causing the Voice Only Network pop up message?

It's still unknown exactly why. It only shows up on Custom ROMs for Verizon users whenever the "Extended Network" ERI is displayed on the phone. "Extended Network" is displayed when you lose service or leave the Verizon owned and operated coverage area and are "free" roaming on another cellular provider (like US Cellular or Cellular South). This fix disables the roaming and extended network ERIs thus no more pop-up message.


2. What is the Enhanced Roaming Indicator (ERI)?

To simplify it, it is the fancy text that is displayed on the Today (main) screen that says "Verizon Wireless" or "Extended Network."

3. Can I get roaming charges from using this modified PRL?

This PRL is exactly the same as the official Verizon Nationwide PRL with the same version number except for the text on the Today screen. As long as you are on a current postpaid Nationwide plan, you should be fine. With that said, use at your own risk!


4. How do I get the original/official Verizon PRL back?

Easy, just call *228 and select option 2. The "Verizon Wireless" text will magically reappear after the phone reboots.


5. All of a sudden, "Extended Network" or the pop up returned. What happened?

Verizon's OTA programming system pushed you a new updated PRL. Don't panic. Follow the install instructions again and reinstall the modified PRL.


6. How often should I update the modified PRL?

Verizon lately has been releasing new PRLs at least monthly. I will try to post an updated modified PRL within a few days after a release. It is not a necessity that you have the latest PRL unless you are having voice and/or data coverage issues. With that said, I would recommend updating your modified PRL at least every quarter.
