Firmware Change Update On Blackberry 9790 Bold ^hot^ -

To update or change the firmware on a BlackBerry Bold 9790 , you must use a Windows PC equipped with specialized legacy software like BlackBerry Desktop Software and the AppLoader utility . This process—often referred to as "flashing"—allows you to repair software errors (like the notorious Error 507), change system languages, or upgrade to the final official release, BlackBerry OS 7.1 . Prerequisites Before starting, ensure you have gathered the following: Drivers: Install BlackBerry USB Drivers or BlackBerry Desktop Software to ensure your PC recognizes the device. Firmware File: Download the official OS file (typically an .exe ). For the 9790 Bold, look for versions like 7.1.0.1098 or 7.1.0.1033 . Note: Choosing a file with "AllLang" or "Multilanguage" in the name ensures you have all language packs available. Tools: You may also need the BlackBerry Swiss Army Knife (BBSAK) if you intend to "wipe" the device entirely before flashing. Step-by-Step Firmware Update Process
