Step-by-Step Guide

Step 1: Make sure you are trying to flash a CDMA phone.
CDMA stands for Code Division Multiple Access.
If you are uncertain whether your phone is CDMA or not, remove the battery and look for a removable subscriber identity module (SIM) card under the battery.
If there isn't a SIM card, you indeed have a CDMA phone that can be flashed.
GSM (Global System for Mobile Communications) phones can't be flashed (like AT&T and T-Mobile).
Metro, Sprint, Cricket, Boost, Verizon and many others are CDMA and thus can be flashed because they're not controlled by the SIM card. (Since Metro has merged with T-Mobile they have introduced phones with SIM cards so flashing may vary from phone to phone.) Your phone must also have a clean ESN (electronic serial number)
-- that is, it must never have been reported lost or stolen. -
Step 2: Get out your USB cord.
The same one you use to connect to your computer to download music and whatnot will be used with this process. , There are several easy-to-use flashing programs that make flashing easy, and some are even free to download.
Make sure the one you choose will work with your particular phone before attempting to flash.
Examples include Easyflasher.com, CDMA-ware.com, and Your cellular.
Search around before you risk damaging your phone with an inadequate or incompatible program. , You are changing your phone from your current carrier to something else.
The only stipulation is that it also must be a CDMA network.
Cricket, Page Plus, and Metro PCS are three popular options.
You can check the reception in your area for various carriers at Cellreception.com.Might as well before you make the leap! Certain programs are affiliated with larger networks, like Page Plus is with Verizon.You can get an hour's trial of Page Plus from their website. , Carefully read the instructions and follow them carefully.
After reading the instructions, you will be able to flash your phone within 15 or 20 minutes.
Because each phone's set up is a bit different, it's impossible to outline step-by-step guidelines here.
However, there are generally a few things you need to know that we'll try to cover. , If you're unsure whether your phone is up-to-date or not, it's fairly simple to get the latest online.
As long as you know your phone's model number or name, you'll be good to go.
If you don't, you can find that online, too.
Make sure you have all the drivers you need before you flash! Otherwise the process may not work.
Visit your phone company's website (e.g., Samsung) to do so. , The software will ask you what your original carrier was, what you're flashing to, and your phone's make and model.
It will also prompt you to choose between a "half flash" and a "full flash." A "half flash" is just talk and text, nothing else. , If you get into the program you're using to flash, you can "read" the phone, which will then give you all the information you need to continue with the process.
Or you can get into it beforehand.
The MEID and ESN can be found underneath your phone's battery.
The MEID will be 18 digits (starting with 2) if it's MEID Dec or 15 numbers and letters if its MEID Hex.
The ESN will be 8 numbers long and possibly labeled PESN., Your software should have an option to detect your phone, allowing it to be read.
If you do this, you don't have to worry about determining the COM port yourself
-- it should be able to figure that out for you.
If it is asking you your unlock code, for Verizon phones this is always six zeroes.
The lesser common, but still possible, options are six ones or six threes.
Certain phones may require you to mess with the PRL.
In the US, the code is *228 (for Verizon/MetroPCS/US Cellular) and ##873283# ("update," in case you didn't notice) for Sprint.
In Canada, it's *22803 for Telus Mobility.
If for some reason the COM Port is giving you guff, you can manually find what port it is in through your Device Manager. , Most software will have you select "write" and then ask you to confirm.
Once you select "yes," the phone will proceed to get flashed and automatically reboot when successful.
That's it! You're done.
Almost too easy, huh? , This is the term used for a "sudden death" of your phone.
It becomes virtually useless...unless you want to use it as a brick.
This risk still exists even when done by a professional.
The odds are lower than if you ask your geeky roommate to do it, sure, but it's still there. , However, if you go to a retailer and they do it for you (which is an option), your warranty may stay intact (depending on your circumstances, of course). , If you're flashing to Boost or Cricket, you shouldn't have a problem.
But flashing to a behemoth like Verizon could pose some issues
-- they approve of fewer "at-home" remedies such as this. , When you're working with a CDMA phone, whether it's flashed or not, you'll still be relying on CDMA technology.
If you live in the US and travel a lot, most phones in other countries are of the GSM variety (i.e., have a sim card).
The main benefits of flashing your phone are in saving money and supporting the littler guys.
All carriers within the US with the exception of AT&T and T-Mobile use CDMA technology.
Their numbers (ESN) are hard-wired and cannot be changed, unlike their GSM peers., You need to replicate your phone's ESN to do this, thus cloning it.
Having two phones with the same number is obviously fishy and is a crime that could lead to some hefty fines or more.If you are contemplating Straight Talk, see their website and talk to a professional beforehand. -

Step 4: Know what you want to flash your phone to.

Step 8: Know the basics.

Step 9: Know your MEID and ESN.

Step 10: Detect your phone.
-
Step 11: Choose "write."
-
Step 12: Know that "bricking" your phone is an option.
-
Step 13: Understand that any warranty you had will be voided.Makes logical sense -- you abandon your carrier
-
Step 14: they abandon you.
-
Step 15: Make sure your flashed-to carrier accepts foreign ESNs.
-
Step 16: Know that you're still using the same technology.
-
Step 17: Flashing your phone to Straight Talk is illegal.
