Flash or Flashing--Technically, flashing refers to the overwriting or re-writing of the phone's firmware. There are many phones which can be flashed to cricket with all features working. On most CDMA phones, programming the phone can be done "over the air" by dialing a special code, usually *228 or some variation. Colloquially speaking, flashing can also loosely mean making a phone from one carrier work on another carrier. The easy way to tell the difference is that if your phone does NOT take a SIM card, then it is probably CDMA.

To flash a phone to cricket you will be overwriting th phones firmware. The firmware is software in the phone that doesn't change when you turn it off, and it cannot be deleted unless it is overwritten, hence flashed. It requires specific files called prl files.PRL or PRL File--Short for Preferred Roaming List--A small text file containing instructions for how a phone connects to a specific network's radio towers It is usually loaded by connecting the phone to a computer to overwrite its data. There are a few tools used such as a pst PST--Short for Phone Service Tool or Tools--Special software used by phone manufacturers to program their phones. And also a monster file - -"Monster File"/"Monster Pack", ROM, or "Kitchen"--System software that is needed to flash a phone.

In almost all case you will need to access the phones service programming menu- - -Service Programming Menu--A special menu typically hidden from the primary User Interface that allows for "deep programming" of a phone.You will also need access to msl and spc codes specific to the device you are flashing.MSL/SPC--Special six-digit codes needed to access service programming features on the phone. Access to the service programming menu can be disabled in a phone's firmware.

Depending on your phone, it may require extra steps to unlock or get WAP and MMS working. That is why you need the msl/spc codes to allow deep programming to unlock these features. Not all phones will be capable to access wap or send and receive mms.

Ringtones generally have to be prepaid using a flex bucket. It is best to download ringtones before you flash your phone to cricket since they have a limited selection of ringtones and wallpapers.There are cases were flashed phones will not be able to download ringtones directly from cricket.

The details outlined above will not only work with cricket but you can also flash phones to metro pcs using the information provided above. It is best to do all your research before purchasing your phone to ensure that the cell phone you are interested in can be flashed to cricket or metro PCs

There are three programming/service menus I know of. To access all of these, you dial the number and hit send. Some you need to put in a second code afterward:

Programming Menu:
##PROGRAM11000
(hit send)
Enter: 000000

LG Service Menu:
##LGSERVICEMENU
(hit send)
Enter: 000000

Test Menu:
##SERVICE
(hit send)

Be CAREFUL, you can brick your phone with some of these options (i.e. kill it).

just type 00000000,this is the default lockcode for samsung.
