How to Unlock Blackberrys

Unlocking 8XXX model BlackBerrys

Preface: This process only works on GSM model phones(At&t, T-Mobile). Do not attempt to do this to CDMA Phones (Verizon, Sprint). These Instructions must be followed in this exact order, with the correct versions of the software supplied in the Blackberry folder, otherwise this will not work.

Step 1.) Begin by installing the BlackBerry Desktop Manager. I have supplied version 4.7 It seems to work the best. The newest version of this software was not working correctly.

Step 2.) Install Microsoft’s .Net Framework. The unlocking program needs this to run. Odds are you already have it, but run the included file anyway to make sure.

Step 3.) You need to have the Blackberry Operating System Flashfile for the phone you intend to unlock Installed on your computer. This may not be necessary, And may be removed from future revisions of this guide. For the time being just run the included software for the phone you plan on unlocking. Versions 8100, 8110, and 8310 are included.

Step 4.) Install MFI Multiloader. It is in the MML Setup 1.1.8.3 Folder. Do not run it yet.

Step 5.) Navigate to the MFI multiloader install directory. It should be C:\MML . Next you want to go to the supplied Blackberry folder and open the MML Copy Files Folder. It will have a folder inside called MML. Copy and paste this folder to the c:\ directory. The root of the C drive. You will be overwriting some files so if it asks you if its ok, just click ok. We want to replace those files. If it doesn’t ask you, You did not do something right.

Step 6.) Open the MML Config File Folder, copy and paste Configuration.xml to C:\MML\Configuration. This enables you to use MFI Multiloader while still connected to the internet. Otherwise you will need to disable your internet connection, a real hassle.

Step 7.) Delete the vendor.xml file located in c:\program files\common files\research in motion\apploader

With those steps completed we can get to unlocking!

Step 8.) Make sure the Blackberry is not plugged into the computer. Double click on the MFI Multiloader icon on your desktop.

Step 9.) Make sure that your window looks like the one above. You need to tick the two boxes Full Erase, and Auto Start

Step 10.) Make sure the Blackberry device is turned on before you plug it into the computer. Plug it in and wait. The software will immediately begin to erase the OS of the phone. All you need to do is wait for the box to change from BUSY to PASS.

Step 11.) If it passed, the screen of the device should display a large 1 in the upper left hand corner. Disconnect the device and type S T A R T into the phone using the keypad. If entered correctly the screen should change and say “No Application Linked (Factory OS)”. This is Good.

Step 12.) Close MFI Multiloader and plug your phone back into the computer. Run The apploader from c:\Program Files\Common Files\Research in Motion\Apploader.exe and reinstall your OS. You are good to go now!
