BlackBerry Tips: 2 Ways to Install a Theme or App from the JAD File


There are a few ways you can install a BlackBerry theme from a JAD file and we’ll present two: a free and paid version. Ideally, someone has hosted the COD and JAD files and provided you a link to the JAD so you can download OTA. Often times you’ll find a theme that is exported by a developer as a bunch of COD files and a single JAD. All you need to know is that the JAD points to all the COD files and tells the BlackBerry how to install the theme. If you have ever tried to load these files through the Desktop Manager, you’ve found that it doesn’t support this sort of side loading. Here are two ways in which you can download these files to your device:

BlackBerry Master Control Program (free)

BlackBerry Master Control Program (MCP) is a power tool that allows you to easily load/save/erase any module you want, take screenshots of your device, turn the radio on or off, synchronize the time on your device to your PC, reset to factory settings (remove IT policies), perform a handheld wipe, optimize (in real time) or install any BlackBerry OS. To install a theme from a JAD file, simply load the JAD file in the JAD/COD file section, and load them to your device with a single click. MCP also lets you create JAD and or ALX files. This is helpful for loading themes by the Desktop Manager, or letting you load the JAD to the device to be installed as per below.

Filescout by emacberry (free version and $5.99 after)

FileScout is a robust file explorer for BlackBerry. In addition to its ability to browse the file system, you can create directories, copy, move, rename and most importantly (for this purpose) you can zip and unzip files. When you download the COD and JAD files, you can zip them from your PC and email them to yourself, transfer them by Bluetooth or by USB, and save them to the memory card. FileScout will let you move these after having downloaded them, and unzip them to a folder on the memory card. After that, you can just click on the JAD file (usually the smallest in size), and install directly from the BlackBerry memory card.

Before your purchase, download the 14 day trial version. This is especially helpful if downloading the theme is a one-time deal.
