[RELEASE] Latest PRL (51190) For Verizon network using a Sprint PRI (w/Q&A)

I went ahead and extracted and updated the latest Verizon PRL (51190) for America's Choice II with EDVO so it runs with a Sprint Touch Pro on the Verizon network. I did note a few significant changes from the 51101 PRL & the 51143 PRL so it may be worth upgrading to.

Tested on a Sprint branded TP running Sprint PRI's 1.47_003 and 1.53_003 and running on the Verizon network on 12/21/08.

Q. Why would I want the latest Verizon PRL?
A. I provides the latest roaming information for the Verizon network. With the latest PRL the roaming triangle will be more indicative of true roaming notifications.

Q. What are the requirements for this PRL update?
A. You need a phone running on the Verizon CDMA America's Choice Network with a data plan. You also need a phone using a different PRI (Sprint tested, it may work with others, but I did not test) than Verizon's. If you have a Verizon phone running on a Verizon PRI then you will should NOT use this PRL, instead *228<SEND> option 2 should update the PRL for you automatically.

Q. How do I tell what PRI or PRL I have?
A. On the Touch Pro, select the Start menu then Settings. In settings select the System tab and run Device Information. On the Device information screen there will be Items indicating PRL and PRI versions. 1.46_002 is the stock Touch Pro Verizon PRI. 1.47_003 and 1.53_003 are known Sprint PRIs. There may be other ones out there and ones for other carriers, but at the time this was written this was my known subset and only ones I tested the PRL with. If your PRL is 51190 or newer then you do not need this update.

Q. How do I apply this PRL file to my Touch Pro with a non-Verizon PRI?
A. Follow the steps below. Note that a SOFT reboot is required at the end.

1. Unzip the PRL from the zip file and copy it to your device or storage card.
2. Dial **PRL<SEND> (**775<SEND>) on your phone.
3. Enter your MSL unlock code (should be 000000 or six zeros) in the password box and select OK from the left soft key.
4. Select the Update PRL item by tapping or clicking on it with the stylus. Once it it highlighted, select the right soft key labeled Menu and select Edit from the pop-up menu (you could also tap and hold on the item and select Edit from the pop-up menu).
5. Select the Browse button when the dialog appears, then select the 51190m PRL from the list when the list appears. If the file does not appear, make sure the storage card is inserted correctly and that the phone is not connected with the USB cable.
6. Select the OK left soft key.
7. Select the Menu right soft key then select OK from the pop-up menu
8. A dialog box will appear indicating the phone will reboot.
9. Enjoy the new PRL. You can go to Device Information (see question above) to verify the PRL is being used. It will read 51190 in the status screen, not 51190m.

Q. I thought I could use *228<SEND> to update my PRL automatically.
A. You can if you have a phone with a Verizon PRI. If you have a different PRI (non-Verizon) loaded on your phone then if you use *228<SEND> then the PRL that is downloaded will not be compatible with the PRI and the roaming indicator will always show.

Q. Why does this happen and why do I have to do this PRL update manually?
A. It has to do with the mapping of codes in the PRI and PRL. If you have a Verizon PRL and PRI then *228<SEND> will download a PRL compatible with the Verizon PRI. If the PRI is not Verizon's then the PRL file that it downloads will not be compatible with the PRI and PRL codes will not match. The attached PRL file has been modified so that the codes align with the codes the Sprint PRIs expect.

Q. How can I make *228<SEND> work again so that every time I use it the roaming triangle doesn't come back?
A. You will need to install a Verizon PRI on your phone. Check around this site for instructions on how to do that. This will make the PRLs downloaded from *228<SEND> compatible again. The downside is that the GPS on the phone will not work with the Verizon PRI until Verizon decides to unlock the GPS feature. Once this happens I'll most likely move back to a Verizon PRI.

Q. Will this work on a Verizon Touch Pro phone on the Verizon network.
A. As stated above, if you are using a Verizon PRI (if you have a Verizon phone and have not changed your PRI from Verizon's 1.46_002) then you will not need this PRL and applying it will most likely give you a roaming triangle even when you are not roaming. If you are using a Sprint PRI to get around the locked Verizon GPS issue (the current fix does use a Sprint PRI from what I can tell) then this update will work for you. I did notice that the newest Phase I GPS fix for the Verizon phone does appear to contain either this modified PRL or one that someone else modified. Either way, you can check your device properties to see the current PRL version and if it is older than 51190 before applying this update.

Q. I went ahead and applied this to my Verizon phone with a Verizon PRI by mistake now I have the roaming triangle all the time. How do I fix this?
A. Dial *228<SEND> and select option 2. This should update your PRL automatically to the latest Verizon version and the roaming triangle should now indicate correctly.

Q. Will this work for other phones with a Sprint PRI on the Verizon network?
A. Most likely but I did not test any scenarios other than the Touch Pro. Your mileage may vary.
