Blackberry 9720 Device Software Download Better [2021] File
Since BlackBerry officially ended legacy services for the 7.1 OS on January 4, 2022, the original download site is no longer available. To update or "flash" your BlackBerry 9720, you must use archived files and desktop tools. 1. Essential Software & Drivers
Step-by-step: Download and install device software
- Install BlackBerry Desktop Software (or BlackBerry Link) on your PC.
- Connect your BlackBerry 9720 to the PC with a USB cable.
- Open BlackBerry Desktop Software / Link and allow the computer to recognize the device.
- In the software, choose “Update” or “Reload” device software. If the app offers to check for an update, accept.
- If you have a downloaded .IPD or .BAR file (carrier-specific firmware), use the Desktop tool’s “Load” or “Reload” option and point it to the file. Follow on-screen prompts.
- Wait for the process to complete — do not disconnect the phone until finished. The phone may reboot multiple times.
- After installation, verify settings, restore your backup, and re-check network connectivity and apps.
- Do not use the phone's built-in updater.
- Do find OS 7.1.0.1842 on archival forums.
- Do delete
vendor.xml. - Do install via
Loader.exeand wipe first. - Do disable compression for speed.
- Check File Integrity: Use checksums (MD5) if provided by the source to ensure the file is not corrupted. A single byte error in a
.codfile will cause an “Invalid COD” error during installation. - Prefer OTA (Over-the-Air) Hosting: While sideloading via USB works, downloading directly on the device via a hosted
.jadfile is often cleaner. Users can upload their verified apps to a personal Dropbox or a small web server and visit the link in the BlackBerry browser. The 9720’s browser is ancient, so ensure the file link is direct (ending in.jad) and the server uses basic HTTP, not HTTPS (as TLS 1.2 support is limited). - Clean Up Before Downloading: The 9720 has limited internal flash storage. Before downloading a new OS update or large app, delete unused apps, clear the browser cache, and move all media to an SD card. A device with less than 20 MB of free memory will fail most download and installation attempts.
