    This is what I did I have LG optimus m
    1. Make sure USB debugging is enabled
    2. Download USB driver and install on your computer
    3. Download 3020 prl or New Prl 3022 Credit goes to LockLady OR even newer PRL 3023 latest prl 3024
    4. Download and install qpst 2.7
    qpst 2.7
    5. Connect phone to computer
    6. Open device manager expand ports and make note of what com port your USB device is on
    [​IMG]
    7. Open up qpst configuration if com port is not shown select add port and enter com# (# being the one seen @ device manager)

    8. Select service programming (phone must be selected to continue)

    9. On the main menu setting tab click read from phone and will obtain phone info it will ask for ur spc
    [​IMG]
    10. Spc code can be obtained through cdma workshop or by using checkesnfree.com Get Spc
    11. Look for roam tab and there will be an option under preferred roaming to search for new prl locate it and select write it will ask for ur spc code again

    note I'm not responsible for bricking ur phone I've done this before and familiar with the software even though this quick tut should be noob friendly

    Is this safe? If it messes up can a nandroid restore fix everything?

    it does workwith optimus m
    you must have usb driver installed and enable usb debugging for it to work

    after i manually update to prl 3020 i did 228 update and it reverted back to 3019 so i redid the whole process and it worked

    where are u stuck?

    its safe as long as you follow steps provided and dont venture within qpst and start changing random things within the program

    im running stock so im unsure if nandroid restore will work in case u misread or fail to follow instructions

    again ive recreated the above steps couple times and had no problem everything worked smoothly

    if you do something to your programming a nand restore will not fix it, So as he says dont mess with anything other then what is listed.:D

    did you get the spc from the checkesnfree.com website?

    did you at any point change the spc for your phone?
    was the phone new when you got it.

    when you get your spc from the site maker sure its meid dec
    press far left left key this will get u into settings
    select about phone > status
    and look for meid dec
    when entering meid on site make sure metropcs option is selected

    when does it say session terminated?

    like new optimus said if phone was bought new spc should be same as checkesnfree.com but, if bought used there is a possibility previous owner changed it, most users change spc to all zeros but that may not be the case

    I did this last night and it was amazingly quick and easy. Literally took less than five minutes after I got the program downloaded. I was ripping my hair out trying to get LGNPST to work yesterday.

    I couldn't get that site to work yesterday, either. I downloaded MEID Converter for free from the market and I had no issues.
