I decided to take the leap and try it on the Nexus and it worked. I have horrible sprint coverage at work and can't even get 3g, but you cannot force the phone to roam to a nearby Verizon tower. Now after this method I have full bars, 3G and 1.9 MB download speeds.
As always I'm not liable for anything that could happen to your phone or Contract. If you want to switch back just follow step 2 with a sprint PRL or use "Update PRL" in about phone if its included with your ROM. (Flash back to stock if not)
I can't find the previous thread as it was so long ago but here is exactly what I did.
1) Get Any Cut from the Google play store.
2) Put the PRL you want to use on the root of your Internal Storage and rename the file to Test.prl *Make sure you unzip the prl and put it on the root of your internal storage. Ex. Take 00001.prl out of the zip file and rename it test.prl. (Some people have noted that TEST must be capitalized, it isn't for me but if it fixed it for those users there's no harm in trying.
3) Create a new shortcut in Any Cut, Click Activity, scroll down and select PRL Write.
4) Go to your home screen with the shortcut on it and click it. After a few seconds your phone will restart.
5) Check your PRL version in About phone and it should reflect the change. Note: it may take a minute to update.
I'm in awe that this worked so easily and the first time as many of you know changing a PRL is usually not for the faint of heart. So I'm still a bit skeptical but "Not Roam control" also says I'm on the Verizon Network. If you try this please post back with your results. Also please make sure you know your coverage on Sprint vs. Verizon in your area. You won't notice any difference if your sprint coverage for your area is better than Verizon. In Ohio ( My area anyway) Sprint coverage is terrible, but Verizon is amazing.
I use 00001.prl and 00002.prl which are modified Verizon prls that will not return the roaming indication.
Users have also noted that the Rom and Kernel Versions may cause some issues with the Write PRL in Anycut. I'm using Black ICE 34.70 and Francos Kernel Milestone 3 and don't have any issues.
I have made a nice little shortcut system using Tasker. Since I dont have the "Update PRL" on my rom. All I need to do is change home screens click whichever PRL I want to run then hit Write PRL and phone reboots with the correct PRL.
Create two folders on the root of your internal Storage, one called Sprint, one called Verizon (Or whatever you want that describes your PRL).
Inside those folders drop the respective PRL files already renamed "test.prl".
Using Tasker or any other app that supports deleting/coping files, create a new Task Called "SprintPRL".
Add two Actions, the first is a Delete File, File location is /sdcard/test.prl
Second Action, Copy File From Sprint/test.prl To /sdcard
Now do the same thing for your second PRL changing the Copy file From location to point to the second location.
Now you have two tasks that will delete the file on your Internal Storage and copy the PRL you want in its place.
Using this method has some nice perks as you can set Tasker up to fire off when you are in a certain area you know you have bad sprint coverage. I'm going to do some research today to see if I can trigger the PRL update activity from Tasker and make it completely hands free.
I have used some NFC Tags and NFC Task Launcher to Fire off these but I still have to manually click the update PRL shortcut with Anycut. Once I solve that problem I'll post it here as well.
Enjoy Guys n Gals!
