    Default Samsung Prevail M820 Cricket flash...Help please

    So I have a Boost Samsung prevail M820 that I am trying to flash to Cricket. This phone is kind of irritating me. It seems like you have to do everything manually. I got the prl loaded thru CDMA ws but it won't let you write ANYTHING else. It says access denied. I found a page with all the ** commands but still no luck. When I go into the browser and enter the gateway ip address nothing happens. So stuck at talk and text at this point. Any help who be greatly appreciated...
    Hopeful up and coming flash guru Grateful for all the guidance along the way...

    There seems to be a lot of 'security' on this phone from Boost, they really do not want you to flash it easily. So you'll be hard pressed to do any of the programming through a PC.

    ANYWAYS.. here's what I did

    1. Plug in phone in debugging mode
    2. adb shell getprop ril.MSL
    3. ##8778# > USB Mode
    4. CDMA Workshop > Unlock with MSL, won't let you write SPC but that's ok
    5. CDMA Workshop > Write PRL
    6. Unplug phone
    7. ##SPC# > Edit > write MDN and MIN > Done

    On reboot the phone should be half flashed.

    Full flash programming would have to be done in ##DATA# then most likely normal Samsung Galaxy steps.

    this phone not answer on nv commands like other phones. But you can program it completely by using QPST EFS explorer.
    In nvm/num you can see a bunch ot txt files named as digits. It is nv items by numbers. If you know wich nv you want to
    edit - just copy it, edit and write back. when edit all - just reboot. Works in metro pcs voice/text/internet - i tested on my own number
