(1) Install the drivers for your device.
(2) Connect to CDMA workshop and read SPC (LG method), then write to 000000.
(3) Write the PRL of your choice.
(4) Write your MDN and MIN
If everything was done properly you will now have Talk and Text, these settings should stick
without any problem. But if something weird happens just do it again.
For the PRL I suggest trying chrisngrod’s new Cricket/Sprint Hybrid PRL, since reportedly you
may be able to use talk and text in areas where flashed phones normally do not pick up. This
PRL must be written with QPST, as of yet it doesn’t work with CDMA workshop.
2. Obtaining Root and Flashing Custom Recovery
If you know what are you doing, or don’t want to bother with custom ROM’s you can skip this part.
If you decide not to use the Cricket ROM by Error420 you will need to install the Indulge’s MMS.apk,
push telephony.db, and possibly adjust the APNs.
Now we can flash a custom recovery in order to install the [Only registered and activated users can see links. ]
