    I have the same problem with a brand new juke phone. I took it into the store and they could not unlock it. They gave me a new phone in within another week the same thing happen again. There is something definitely wrong with this phone, its not the user.

To unlock it you have to use the las for numbers of the telephone number of the device. That is it and no other way around.

    If that does not work for you (guest's post), get a USB data cable for your phone (considering you have valuable info and what to retrieve it). It should cost around 5 bucks online. Once you get it, download from samsung's web site a program called Samsung PC Studio 3 (this only will provide the drivers so the phone can communicate with your computer). Once installed, restart the pc (do not connect the phone to the pc yet). Once the pc is ready, connect the phone to it and open the Samsung PC Stuudio Software. The OS will load the drivers for your phone. Now go to a webste called and download a software called BITPIM. Install it. Once it's installed, open it up. You have to manually configure the phone so Bitpim can see it. In Bitpim, click on "edit" then "settings". In "settings" look for the option "Phone Type" and choose "Other CDMA Phone". On the "Com Port" option, click "browse" and choose the one for your phone (if more than one appears, try one by one). Once you have it alright, click on "view" tab and check "filesystem". Once filesystem appears on Bitpim's main window with a "+" sign next to it, expand it and start surfing through your files. Good luck.

    P.S: Once I had that phone with Metro Pcs and I had to do that to retrieve ny daughter's birth pics.

Security code for Samsung SCH R400


I'm not sure if this will help but I would first try the last four digits of the phone number you saw in the phone. I would then try these , 1234, 0000 and the last four of your phone number.

Question: While activating with Metro did they instruct you to edit the NAm setting in the phone? If so,.. did you enter your phone number?

Question: You mentioned that there is a lock code. Do you see a lock code soon as you power the phone on? If so this is a user lock.
Or,.... do you see a lock code when attempting to edit the phone's NAM settings? This would be a subsidy lock.

Thank you
