Default OS: 8820 (Multilanguage)

* Download Software

BlackBerry Handheld Software v4.5.0.304 (Multilanguage)

Package Version:
Consisting of:

* Applications:
* Software Platform:
* File name: 8820M_PBr4.5.0_rel304_PL2.7.0.108_A4.5.0.181_COSMO TE.exe
* File size: 92.55MB

Note: The Software Platform and Applications version numbers can be found under Options-About screen on the handheld.

* Download Software:

This download is work on ANY carrier's 8820 model BB. (Not 8800 or 8830)

1. Download the above OS file to the PC then install it to the PC by running (double clicking) the file you downloaded. (Vista users be sure to right click on the .exe file and select "Run As Adminstrator.")
2. Go to c:\program files\common files\research in motion\apploader and delete the file named "vendor.xml."
3. Plug in BB and double click on "Loader.exe." It's located in the same place as the above vendor.xml file.

The process takes about 45 minutes to an hour depending on how much data you have to backup and restore during the process. Once it's done loading the new OS it will reboot (it may do this twice during the entire process.) You will see a white screen with an hourglass for up to 20 minutes at a time while the DM says "waiting for initialization."
If, for some reason, you end up with a white screen with small icons and the number 507, simply connect to the PC again and run Loader.exe again and it should load the OS to the device.

Previous OS version here:

Default Neither Loader or DM will recognize the device

I've tried to follow the instructions here, but neither Loader or DM will recognize the device is attached, and there fore won't load the OS.

Any suggestions?
