I want to flash a metropcs phone to cricket


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

Have a lg vx1000s that was verizon flashed to cricket. It has been hooked up through cricket previously, however i spent 12 hours trying to hook it up yesterday, finally got far enough that they took my cc...


Try *22804 it seems to work for verizon phones that are failing on *288 more often than not.

However if your phone was fully flashed you may need to have it reprogrammed since these phones need to be programmed to your number, without this most likely you will only get talk and text.

I HAVE A SAMSUNG CRICKET SLIDER SCH R 450 AND I CAN NOT GET IT OUT OF SILENT MODE ACTIVATED I TRIED ALL SETTINGS AND EVEN REMOVED BATTERY I AM FRUSTRATED THANKS PAT


Consult your users' manual that came with the phone. Look for information regarding a "Master Reset". Any information *not* stored on your SIM card or in other card memory WILL BE RESET and LOST. This includes any settings you may have made to include the mistaken setting of silent mode.

If asked for a master reset pass-code, common Cricket/Nokia codes read like luggage combinations...

Try "0000" or "1234".
If it asks for a 5 digit, put in 12345.
If it asks for a PUC, call Cricket 1-800 service hot-line from LANDLINE with the cell phone in hand and operating properly.

Make sure that your battery is fully charged before starting the master reset sequence! Good luck. :D

actually, it is not possible to download ringtones to a Rant from Myxer. You have to use a phone uploader with ringtones from your computer and send yourself a "jump code". Unfortunately, Cricket does not offer this option.
