First go to the ZTE Warp forums and give aenoch thanks. I just used his tutorial and modified it for our Prevail. Also download the DFS Software in his original post. http://androidforums.com/warp-all-t...ur-msl-prl-not-cdma-workshop.html#post4474168 The DFS software is a free demo version, but it works perfectly fine, doesnt have a time-limit trial (like CDMA WS), and is much easier to navigate IMO.
If you are on CT Mod 3.75, you DO NOT need to change roms, the hidden menu has been put into CT Mod 3.75. Thanks Bloodawn!
As always make a backup in CWM. Youll really need to do this since you will more than likely need to change ROMs.
Download and flash Half Ass Rom. Make sure you do a wipe. http://androidforums.com/galaxy-pre...2-rom-gb-2-3-6-halfassrom-1-0-stock-ext4.html Thanks to Kouma for Half Ass Rom.
After flashed and booted up, go to the dialer and dial ##7678#, enter MSL, then select DM mode.
Connect phone to PC, and open DFS.
While the phone is in DM Mode, its good to make sure the screen stays on.
After the countdown screen, click on the "Ports" button (top left)
Then double click on SAMSUNG Android USB Diagnostic Serial Port
Close the DFS Port Manager Window.
In the SPC box (top left) enter your MSL number, then click the blue arrow next to SPC
In the Log, it should say DEVICE UNLOCKED
Click the "Programming" tab, then click the "NAM" tab
Backup PRL by clicking "Read" then "Save" (bottom right)
Click "Load" then navigate to a PRL saved on your PC
When you have selected a PRL you want, click on the red "Write" button.
In the Log, it should say OK.
Last step is to click the "Reset" button (top right). YOU MUST DO THIS FOR IT TO WORK!
Your phone will reboot, and you can check that it worked by going to Settings, About Phone, Status, and see that you are on the PRL you selected.
Make sure you go back into the dialer and ##7678#, MSL, and change your phone back out of DM mode.
Now you can go into CWM and restore your backup of the ROM you were on (make sure you wipe) and the PRL will stay changed.
I take no responsibility if you brick your phone, or anything bad that may happen, but everything should work fine if you follow instructions.
