Mystic Miko's way works
Im a MetroPCS rep. and i did the master reset then took the battery out the phone, after that the phone will need to be reprogrammed...you will lose your contacts but will be able to use the phone when forgetting the unlock code.

I bought mine from someone and i did this code and yes the phone has to be reprogramed but it erased everything including the number there.
Just so you know that metro pcs charges $15 to Activate and $15 to retore the phone so if you did retored it to the message you get is reprograming needed donnot pay the 15 their ask you fo cleaning the phone as i was told there.
You did it already just pay for activation.
Because when you buy the Samsung SCH-r450 for the first time that is exactly what you will see on the screen before they program the phone. Please dont get fooled into paying more money than you have too.

I hope this helps you guys out.
Thanks!

If your phone is blocked. Take it to your nearest network providers outlet, to get it unblocked.

If your sim card is blocked. Go to your network providers website, where you can obtain the puk code to unblock the sim card.

    The Samsung SCH-R450 is not a GSM phone and does not use it a SIM chip...
    This particular phone is on a CDMA type network,,,, wich does not use SIM chip technology

    Flashing a phone... or in the case of most GSM phones... is what is done when you want to unlock it... unlocking is removing a chunk of code that says... " i can only be used on this providers network!".... or yes ... you can flash the phone with the original info or even lock it to a different network.
    The codes up above are general codes used by service technicians to find out various different debugging information and to perform tasks... such as... a master reset.... which resets the phone back to brand-new out-of-the-box factory settings... with all the memory erased.... all contacts, pictures, texts, mails, everything.
    This same thing as I mentioned above... can be done by flashing the firmware. the biggest major difference is.... when flashing a phone... you can change firmware versions.... and in most cases this is the only way you can downgrade your firmware to a previous version. BUT BEWARE.... if something goes wrong while flashing... you can "brick" your device....

    ****they also flash CDMA phones in some cases to unlock them. **** general codes for most samsung techs

    ***just some things i realized weren't very accurate a lil too late :P

I need drivers for a sch-r450 need cdma drivers


Go to samsung website. The R450 have no driver. but download the drivers for any of their phones.
www.samsung.com
download center
prodecut category
mobile phones
metro pcs
sch a610
software
try that driver,if it does not work, then keep downloading drivers until one works, but this driver worked for me and my other friends.

Windows Vista have the drivers needed. But Windows xXP does not.

Also if the phone is not working with your memory card. move everything on your card to your computer and make a file for it. Then reformat your memory card from your phone. Then transfer back your files. Now my music and pictures are showing up.
