Hi.

ADD. MTsol reported he(she) flashed PRL with QPST without problem so you can use QPST if you have one.

Here's my second thread about PRL writing for our Optimus G with LGNPST.
I'm not sure if I can share the LGNPST here or not so just pm me if you need it.

You don't need root access for this but you MUST HAVE your OG's SPC.
Follow this http://xdaforums.com/showthread.php?t=2032431 thread and get SPC first.

You can always go back to original PRL by Updating PRL from your OG.
`System Settings -> System Updates -> Update PRL'



Let's get started.

1. Make sure your phone is Diag mode enabled. (you can find out how to from the link above.)

2. Open LGNPST.

3. Connect your OG to your PC as Charge Only mode.

4. You will see this screen, click PRL/ERI tab then check Write, NAM1, NAM2.

5. Load the PRL file you want to use. (You can find PRLs from here http://xdaforums.com/showthread.php?t=1880781
or google it and you can find PRLs easily.

6. Press start.

7. It will ask your SPC.

8. Just wait... Your OG will reboot by itself.

9. Done. :good:

P.S. If LGNPST pops up an error MSG, just reboot your OG once then press ok button.

P.S.S. Dang.. picture size is too big... I'm gonna make them smaller later....:cool:

Can you explain why you would want to do this? I can update my prl from the settings menu. In what circumstances would this be a useful process?

For instance, if you are on Sprint and you have awful 3G data, you can use a Verizon PRL and get much better 3G data.

Caveat is if you overdo it, Sprint can terminate your services/contract.

I have tried everything I can think of to change my PRL to Verizon's. I've followed and read through these threads and just can't get it to work.

I'm running ZVB with IAJB 1.1.0. I also tried it with Imperium 2.0.1 ##DIAG# is enabled and not locked. I've gotten my SPC, and lock code. I've changed the Com ports to the 2 options it gives me. I even tried a different Com port that wasn't being used. LGNPST just sits there doing nothing. I've tried reboots. Checking both NAMS, 1 NAM. USB debugging on and off.
Any ideas?

Have you tried qpst? That's what always works for me.

I'd prefer to use LGNPST, but that was going to be my last option. I have qpst installed now. I just haven't found any good instructions on how to use it for the LG. What instructions are you using?

Well, I got it using qpst, but what a pain in the as* to use! Lgnpst seems so much easier. I still would like to know how to do this using lgnpst.

if all you need is force roam to verizon network,
Here's another method. this works perfectly for me.

Dial 3845#*970#

Scroll down to the bottom and select IOT Hidden menu

Select CDMA Setting

Select CDMA Preference

Select Band Preference

Change value to Cell only

Change this value to Any if you wanna go back to Sprint network.

I used that to get my SBC and lock numbers, but it wouldn't write a PRL. It acted like it did, but on reboot.... Nothing.

Thanks guys. I spend a lot of time at our cabin in the mountains. And Sprint sold the tower we used to use to Verizon. I just need to have an alternative for people to get ahold of me. (Old parents and the kids)
Whether it be with the phone to change, or a simple computer program that doesn't require me to have to look it up to change. Thanks again.
PS. Growing older is not for the weak. ;)

Sprint got many calls about us losing service in that area and we were all told it was sold to Verizon and they had no plans to lease it from them. Unless they had more users for it.
So most people switched to Verizon and they all have great service. Those of us still on Sprint, our signal fades from 3g, to roaming, to nothing, all while standing in the same spot.

    Have you notice hand free activation coming up after reboot since flashing a prl?

    Sent from my LG-LS970 using xda premium

    Mine doesn't do auto update.
    Probably because I'm using unlocked bootloader on my phone?
