You must have an OS installed on your 9550 which includes Russian.
You need to find and install to your PC an OS file with "all languages" in the filename.
Device operating system releases are "released" by specific carriers once they have certified and trained their support techs, but still, you are able to load to any carrier's same model by following the instructions below.
See the link below for the download, and follow these simple installation instructions.
First locate your carrier and the OS file you wish to use.
Do a backup of your device first, using Desktop Manager > Backup. Close Desktop Manager upon completion.
1. Download the OS file to the PC then install it to the PC by running (double clicking) the file you downloaded.
2. Go to c:\program files\common files\research in motion\apploader and delete the file named "vendor.xml." (You might have another Vendor.xml file hiding on your computer. Open Windows Explorer and under the Organize button (on Windows 7, there are similar tools for Vista and XP) click on "Folder and search options." Under the View tab, make sure that your computer is set to show hidden folders and files. Once you've done this, search your C:\ drive for "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.
Note: Some users might worry they will void their device warranty by loading an OS from another carrier. There is really nothing to worry about. Please read more information on that here: http://www.port3101.org/power-users/296-blackberry
