What is Cell Phone Reprogramming or Flashing?
Flashing is the process of loading specific carrier files to a cell phone in order to have it work with another carrier.

Is Cellular Flashing Legal?
The answer is yes. In fact, the Library of Congress on July 26, 2010 added exemptions to its Digital Millennium Copyright Act (DMCA) covering cell phones. In part the exemptions state that users are permitted to unlock, or as some call it, jailbreak their phones and unlock firmware that ties a mobile phone to a particular wireless carrier. This law actually has been in effect in a loose form for a few years but was reaffirmed by the DMCA on July 26, 2010.

To Flash My Cell Phone What Is Required?
1. Flashing software (which you can purchase).
2. A USB cable for your phone (the same cable used to download music).

3. A computer with Windows 2000 or newer with a USB Port.
4. A CDMA cell phone (see The Networks section below).

Is It Difficult to Reprogram a Cell Phone?
There are a few good downloadable cellular flashing programs out there that will lead you through reprogramming your phone. If you are familiar with files and have moderate computer skills almost anyone and do it. To begin, look for a flashing program such as Your Cellular. I was able to flash my phone in 20 minutes with no experience. Once you have the software for your cell phone, unzip the files and look for the instructions or read-me docs and follow them carefully. This will give you a good overview of what you will be doing. You should be able to complete the flashing process in about fifteen to twenty minutes once setup. You will be flashing a CDMA phone to a CDMA carrier. See a description of the two major networks below.

The Networks
There are two key networks for cell phone carriers. They are GSM or (Global System for Mobile Communications). Examples are AT&T and T-Mobile. GSM phones have a SIM chip under the battery and cannot be flashed. The second network is called CDMA or Code Division Multiple Access. Examples are Metro, Sprint, Cricket, Boost, Verizon and many others. Cell phones on a CDMA network are not controlled by SIM cards and can be moved or flashed to a new carrier.

How Good Is The Service I Am Moving To?
You can check the quality of almost any carrier by going to Cell Reception. Here you can enter in your zip code and get scores for providers in your area along with comments from others using their service.

    “Flashing is the process of loading specific carrier files to a cell phone in order to have it work with another carrier.”

    Actually, Flashing is the process used to install, re-install or upgrade any device where the software resides on a chip(bile Phone, PDAs, PCs & Laptops,etc.). This is usually called Firmwareexcept for PCs & Laptops where it is labeled BIOS – because it refers to the fixed, usually rather small, programs and/or data structures that enable the device’s basic operation as well as implementing higher-level functions. Not to be confused with an OS or Operating System.

  • Brian aka Guppusmaximus

    *Oops* I meant “Mobile Phones” not “Bile Phones”. Though that would be pretty nasty if they had bile-powered phones…*ugh*

  • http://yourcellular.net/need_help.html Mike

    Yes technically you are correct but the article was written with the layman in mind.

  • Brian aka Guppusmaximus

    IMO, people are only “layman” when they haven’t learned what something is or how it works. So, with all due respect, you should present the information accurately so that people will learn it right the first time.

    Trust me, if that program you found doesn’t work for at least one time then that person will have to do some research to figure it out. Presenting accurate information will lessen the confusion, at least somewhat, down the road.

  • http://yourcellular.net/need_help.html Mike

    With all due respect, the information is accurate it is just not stated in the terms you would like.

    “Flashing is the process of loading specific carrier files to a cell phone in order to have it work with another carrier.”

    It’s got nothing to do with what I like. This information is incomplete and inaccurate.

  • http://www.411gatineau.com/outaouais/celulaire.php remonatrix

    Interesting,

    I did not know that this could be done. I will certainly have a try and see how it works out.

    “With all due respect, the information is accurate it is just not stated in the terms you would like.”

    Nice. And correct.

    “It’s got nothing to do with what I like. This information is incomplete and inaccurate.”

    Incomplete, yes. Inaccurate, no.

    I currently have a Boost Mobile Samsung Seek but would like a Verizon Samsung Fascinate. In order to flash the Fascinate would I have to keep the Seek? The seek is just a month old but I want the Fascinate and would like to sell the other one.

  • Mike

    You only need to keep the Seek if you are bound by a contract from Boost.

  • sherri

    can i flash a cricket phone to verizon or straight talk?

  • Mike

    You can not flash a phone to Straight Talk or any other prepaid service. Do do so you would need to clone the ESN ( electronic serial number ) and that is illegal in the U.S.

  • verdague76

    hi there any advice in how to get a real good flashing software with out to much Headache?

  • John

    The website that is listed here is kind of a scam. What they do is upload free software in to one place and then let you download it once you pay them. The software is free on the internet, but I will warn that many of the free versions are illegal to own as they are cracked. The main software used to flash phones is CDMA workshop and it is $99.99 to buy and own from cdmaware.com, but it is useless if you do not know what you are doing. I purchased it and had no clue what to do with it. There is other automated software out there that requires little to no experience to use. Sites such as http://www.remotesquad.com and will actually flash the phone for you if you are looking to have just one phone flashed. I have used them and while a little expensive, you get what you pay for. But rather you choose to have someone flash the phone for you, or do it yourself, just be aware that paying for programs is pretty useless without the knowledge on how to use them, and the site that the author is promoting here is selling free content.
    Just my 2 cents

  • Darknight

    This article is incorrect, inaccurate, and dangerous.

    The link to the software leads to a site that states that their product isn’t available yet, so how could you have used it, and your description of the process is incomplete without giving information as to where to possibly look for more indepth directions. With what you have posted here, and the links you have given, you have left your readers open to possible scams and hardware damage.

  • Levi

    Just an F.Y.I. to all those who think they’re gonna flash their phone to sprint and get service. NOPE! It’s against Sprint’s policies. Sprint will not hook up a flashed phone. The only possible way around this is if you got an “INSIDE FRIEND” with Sprint and that depends on their level of axcess

  • Laurasm

    I was told by the PrePayd no contract carrier that my Galaxy S11 (originally Sprint refurbished phone) purchased through a PrePaYd dealer and then switched to a Page Plus prepaid carrier, that my phone can not be used for any other carrier. I want to try Boost or Straight Talk prepaid service. Is this true? or am I being told this so I have to buy another phone? Page Plus data will not work on my Galaxy S11, that is why I need to change.

    • jimmy

      i’m a flasher for page plus, go back and have them change your prl, then it will work, i do them all the time,

      • Laurasm

        Thank you, I did what yo suggested and my phone works perfectly for the first time since I bought it. I found a dealer in Tucson; he said it was flashed with the wrong code and not every dealer knows there are two codes. I was blaming the Page Plus service and the phone since Feb. I did go back to the person that flashed it wrong a few times and he wanted me to pay another $50 to send it to a friend of his that was a “genius” at fixing phones. Sent from my iPad

        • JImmy

          please feel free to contact me at…daytonajamz@gmail.com …also model # won’t do much good for me, please contact me because there are too many variables to answer…. does it have a locked sim, is it a micro-sim, what carrier, is it a triband, is it currently locked with a carrier, how many alternative companies can you provision to, do you have a dead sim card to provision with, list goes on and on… i could easily suggest 2 programs, but in order to that we will have to enter private info here and i’m sure you don’t want it blasted on the web, so we can google talk, skype, yahoo chat, many ways , i’m afraid to say not a simple answer BUT…..i will guide you through it, or you can install team viewer and a few programs and specific software and i will run the provision myself, Always willing to help a M8, …..Jimmy

  • Randy Dorsey

    I have a samsung gs3 with sprint I was wondering how can I get it flashed to cricket, straight talk, or boost can someone help please

    • the guy

      if your already with sprint i would just stay with them because boost runs on the same towers as sprint so there for would not be any better service and probably worse all your prepaid phones throttle your data at about 1 GB of use where the big names like verizon and att dont have unlimited anymore so they cant throttle your data until you go over your plan on usage but after all that if you still want to take your S3 over to a prepaid you can find some one locally to do it im sure or if you wish to try it your self download one of two tools depending on how well you can use a computer and what type of OS your computer has for widows or OSX you can Odin and you will need to download the keis for your phone so that it will connect correctly to the software or if you use linux or know how to use the command line you wont need the keis just a program called heimdall but i only recommend any of these to someone who knows what they are doing or takes the time to learn otherwise take it to someone who does or you will brick your phone and it will be a very expinsive paper weight its worth the 60 dollars

  • mel

    i have a lg vx5500pp, courtesy of verizon prepaid, (don’t ever use them) their
    customer service instore is terrible, but if i read your article correctly, this phone can be flashed, think of switching, to att, but phone doesn’t have a usb port,
    so am i sol, or is there an alternate procedure?

    • Roberto

      You cannot use a Verizon phone with AT&T. They use different technology. CDMA vs GSM

      • the guy

        if the phone has a place for a sim card you could but it is a little more complicated than just flashing firmware onto a your phone most phones have both a cdma and a gsm radio in them anymore if you didnt cheap out for example the iphone can be used on either they are all the same when they leave the apple factory its the carrier that changes the firmware thats y it cost 700 to by one from apple but only 200 from verizon or att

  • lynda

    For everyone asking “Can I Do” try looking up your phone’s model to see what type it is. This article clearly states that flashing can be done on a CDMA phone. If you have a GMA, it uses a Sim Card. You should be able to replace the sim card to your new carrier if they accept your phone. READ PEOPLE!!! GOOGLE CAN BE YOUR FRIEND!

      You can’t. Verizon phones only work with page plus and metro pcs. If it has a sim card slot you can flash it to simple mobile and other companies like that. However, several programs are needed for that.

  • BMils

    Ok so I was told by a Verizon Rep that I could use my HTC Thunderbolt on the Verizon prepaid network only to find out later that I cant. I was wondering if it could be “flashed” to use on the 3G network? If so how? Or does this mean that Im out the money I paid for the phone because it does require a SIM card? I cant justify paying double the money for the same service I get using the prepaid method. (Yes, I am a cheapskate when it comes to some things like phones). Im not sure what to do and after speaking to another Rep they told me to “flash” the phone but find it online because the stores wont do it anymore.. Any suggestions?
