Make sure to take the necessary steps to protect your data. Back up your device with BlackBerry Link or Sachesi. Be warned, databases may be shuffled around between some versions, so be prepared if the restore is unsuccessful.

Most of the time a leak will be provided as an autoloader. An autoloader is an .exe file, created with cap.exe, that loads an OS and/or radio to your device. Autoloaders delete user data on the device, so they are refered to as destructive upgrades. However, using an autoloader has less of a chance of problems being caused by pre-existing files.

Most of the time the autoloader will be published to mega.co.nz, Google Drive or Bitcasa, but mirrors start to appear shortly after the initial post. If you are experiencing problems with mega.co.nz, we recommend you install the Chrome or Firefox extension.

Once your file is downloaded (and, if necessary, extracted), you should have a 1-2 GB .exe file. For verification purposes, open a command line (cmd.exe) window in the folder that has the autoloader file. Type "

Once your device is backed up, plug in your device, close BlackBerry Link, take out your SD card (if present) and run the autoloader file. A command line window will appear saying "Connecting to Bootrom:". Your connected phone will restart after a moment, and the LED will turn green. DO NOT DISCONNECT THE PHONE. DO NOT PULL THE BATTERY. Doing so has the chance to softbrick your phone, and nobody wants that.

Once the LED is green, the command line will say "Uploading RAM Image" and will give details about the files contained within the autoloader. When the process is complete, the command line will close and your phone will boot.

A security wipe deletes everything on the device, including settings that the autoloader did not delete. This is evident if one sets a device password before using an autoloader, as the device password still is set after the autoloader installs a new OS.

With the security wipe completed, your phone will be ready for setup again. Set up your BlackBerry ID, WiFi networks, location services and license agreement, as usual. After completing the tutorials, you can either restore from a backup or continue without a backup.

In the event that there exist upgrade .bar files for an OS (generally if the OS has been released to a carrier), then they may be installed on top of the current OS with Sachesi. For more details, read the Install section of the Sachesi article.
