Wipe the BlackBerry with JL_CMDER or BBSAK. Then reinstall the OS.
See blackberryfaq.com for help wiping the device.
Get the OS from your carrier, let Desktop Manager install it, or get the latest OS for your model using the "latest OS" sticky post here on the forum for your model. Posted via BlackBerryForums.com Mobile
