Unlock blackberry 8830 with MML

I bought a blackberry 8830, which one I dreamed for a long time, few days ago. But I got some problems in using this new cell phone. The most serious problem is that the 8830 was contract with Verizon, a US mobile communication network provider and I can’t access in China. After many hard trials, finally, I get a perfect solution to unlock my blackberry with MML for free.

I now want to share my experience on unlocking blackberry with peoples who want to use a locked blackberry. You should know, this free solution can not have effect on any model but some special models. As far as I know, MML can not unlock blcakberry 8820, 8900, 9500 and 9530. This unlocking progress can be splited into four steps. First is download softwares and install them into your computer. The second step is restoring blackberry. The third one is using MFI to unlock cell phone. Certainly, you need to install a new OS on your device.

1. Download softwares and intall them.

There are three applications you must use in unlocking a phone. They are BlackBerry Desktop Manager, .NET framework2.0 and MML. Some times, you may also need to download a few dll files.

Desktop Manager can be accesed at their official website. Go to download page here.

.NET Framework2.0 is a free soft by Microsft. Go to download page here.

I packed two MML files for you to choose:

A simplified edition for just 8100, 8110, 8120, 8200, 8300, 8310,8320, 8350, 8700, 8707, 8800, 8830 and 9530. Click here.

A complete MML file for most model. Click here.

Or you may need some dll files. Get them here.

If you find any problem in downloading files, contact me by leave a comment. I can send you one by email.

2. Restore blackberry

Use loader file to renew your phone to Factory OS. By click file name by specific model under HHFiles folder. For example, if you want to unlock a 8830, double click loader 8830.bat. You will continue with the third step when you see “No Application Linked” on the screen.

3. Unlock cell phone with MML

Please disconnect your network before you starting this step. You will see some error in runing MFI when you connet network. Follow this tips:

1. Copy all files to C: directory.

2. Open folder ‘bin’ and double click register.bat.

3. Double click bulding.bat

4. Run MML.exe

Uncheck Auto start.Click start and wait. About ten minutes later, you’ll see a big “1” on your phone screen and a “PASS” on MFI. When you see these, it’s to say, your blackberry is successfully unlocked.

4. Reinstall a OS

Do you still remember I suggest you download Desktop Manager? Use this to reinstall a new OS one your phone and all things get done.

Frequentlly appeared problems and solutions:

1. Cannot create CFP instance. Please ensure the BBCFPCOM driver is registered

You can download the simplified MML edition and run the buding.bat. Or you can do it yourself by input these code in Command Prompt Only:

regsvr32 c:\mml\bin\BBCFPCOM.dll
regsvr32 c:\mml\bin\GRSNVLibCOM.dll
regsvr32 c:\mml\bin\RIMRadioCOM.dll

2. NV library failed to load PRL file. Cannot find PRL-14672-001 on the server

Also I added all these files into the simplified MML edition.

3. Can not find ceutil.dll or rapi.dll in your system

Download them here. I packed the two dll files.

If you get problem during unlocking. You may check :

For anybody has problem to unlock by this method, it is because the new BDManager. You need to copy the file BbDevMgr.exe from c:\mml\bin to C:\Program Files\Common Files\Research In Motion\USB Drivers to replace the original one. Now, the unlock works like a charm…….
