Most blackberry phones are locked to certain networks and this makes it impossible to use them on other networks or with a different SIM card. You can have a blackberry phone bought from Verizon Wireless in the US but might want to save yourself that high roaming cost on your visit to UK but you definitely can’t use it with other carriers like Vodafone or AT & T. Unlocking your blackberry phones gives you the freedom to use your phone with all network carriers in any country, changing your SIM cards at will without being bond to a contract. Apart from this, unlocked phones are much more valuable in the phone market, you can visit Ebay just to see exactly what I’m talking about.
The steps given in this post on how to unlock your blackberry phone isn’t a simple process, but it’s not that hard either. I did it with a Blackberry 8120 so why can’t you? Before you proceed, you can call your network carrier and request for the unlock code but I’m not so sure they’ll give you if it’s a phone bought on contract. You’ve got to find a way to unlock it yourself and you need the following tools to get this done:
You’ve gotten all the softwares, right? Now lets get started! Please note that you’re doing this at your own risk and I’m not responsible for any damage that might arise from this process. You might lose your warranty if you continue…so think about it. If the you follow the process carefully, you should be smiling at the end though when your blackberry phone is unlocked.
Now here are the first things you must do before starting the unlock process:
A. Make sure your Blackberry’s battery is charged to at least 50%
B. Make sure you do full data back-up before doing anything. You don’t actually need this if it’s a new phone.
C. Remove your SIM card, turn off radio, turn off Bluetooth, turn off Wifi or any
connection on BlackBerry.
D. Install Blackberry Desktop Manager
E. Install Blackberry OS (be sure the Blackberry operating system you’re installing corresponds to the phone model!)
F. Install MFL Mutiloader setup.
G. Extract all the parts of MFI Multiloader and copy to C:\MML, replacing the content of the existing conetent in the MML folder there.
H. Go to C:\Program Files\Common Files\Research in Motion\Apploader and delete vendor.xml
I. Disconnect your computer from the internet.
Be sure you performed each of the 9 steps above without omitting one, OK? Now, let’s proceed.
1. Go to the desktop and run MFI Multiloader.
2. Make sure Logging and Database is off.
3. Now connect your Blackberry phone through USB and hit the start button on MFI Multiloader
4. Wait till it shows PASS
5. Your BlackBerry will should show 1 on the screen
6. Disconnect your BlackBerry from PC and close MFI Multiloader.
7. Type START on your phone.
After finishing this operation, your phone can show you message like “error 507″ or “no application linked”…don’t worry, it’s “normal”. Your phone is unlocked now, but you’ll need to reinstall the OS and set it up.
8. Open Blackberry Desktop Manager, connect your phone and click on Application Loader
9. Select “Add/Remove Applications”
10. Choose applications and extras, and click Next
11. Wait until Blackberry Desktop Manager finishes the whole operation. It might take up to twenty minutes or more.
Please note that you’re doing this at your own risk and I won’t be held responsible for any damage you cause to your phone but if you’ve got a problem with the process, I’ll help if I can, only if I can. By the way, some issues can arise after this:
* Device can’t connect on MFI Multiloader.
-Copy BbDevMgr.exe from the C:\MML\bin\, and overwrite same one in the location C:\Program Files\Common Files\Research In Motion\USB Drivers\
* MFI Multiloader shows FAIL.
- You can get this message if your MFI Multiloader version is older. Download newest, and just repeat process. Also be sure you disconnect fro the internet before doing it.
