FlashFire v0.33 Update Brings Ability to Backup and Restore via ADB over WiFi

FlashFire v0.33 Update Brings Ability to Backup and Restore via ADB over WiFi

FlashFire, for the uninitiated, is the work of XDA Recognized Developer Chainfire, a man who needs no introduction to an Android enthusiast. FlashFire is the successor of Mobile Odin, an application that aids in flashing Android devices on-the-go.

The latest update to FlashFire has brought the ability to backup and restore your phone partitions through ADB. These are full backups of your device, but you do have the ability to choose which parts of your phone you want to back up. As an added bonus, the backup and restore options also works wirelessly through ADB over Wi-Fi. However, Chainfire notes that the backups are created and wrapped in a ZIP file in a specific order, which means that you cannot zip existing backed up partitions created on your phone and restore them through adb.

Along with this, FlashFire is also changing a few things related to how it handles Adopted Storage on newer Android versions. To note, FlashFire will always treat your Internal Storage as Internal Storage, and your Adopted Storage as Adopted Storage; this works like this even if you have migrated or swapped the two on your device.

There are a host of other changes too. Some of the notable ones include better startup performance for users with many backups, improvements to back key behaviour in-app, improvements in display of progress information, support for additional partition types and more. The full changelog can be viewed below:


  • Add support for backing up to and restoring from ADB, through USB or Wi-Fi (special ZIP format)
  • Completely reworked progress code, more info is shown in more places now (current file, speed, progress)
  • Improved back key handling
