Flashing Partition Images

The Flash Image tool in Fastboot allows you to write raw .img image files to any partition on the target device (equivalent to running fastboot flash <partition> <file.img>).

How to Flash an Image

  1. Connect the target device in Fastboot mode via USB OTG.
  2. Tap the Fastboot tab in Dioxamine.
  3. Select the Actions sub-tab.
  4. Tap the Flash Image tile.
  5. Tap Choose Image File.
  6. Your host phone’s file picker will open. Select your .img file (e.g. boot.img, recovery.img, magisk_patched.img, init_boot.img).
  7. Dioxamine will inspect the filename and auto-populate the partition name in a confirmation dialog (e.g. selecting boot.img auto-fills boot).
  8. Review or edit the target partition name:
    • For kernels on Android 13+: init_boot or boot
    • For recovery: recovery or vendor_boot
    • For system images: system
  9. Tap Flash.

Live Progress Tracking

While flashing, Dioxamine displays:

  • Circular progress indicator showing the active flashing operation.
  • Percentage bar (0% to 100%).
  • Byte counter (e.g. 48 MB / 64 MB).
  • Completion Card: Displays a green checkmark upon success, or an error message if the partition is write-protected or invalid.

Warning

Flashing incorrect images to critical partitions can cause your device to fail to boot. Always verify that the image matches your exact device model and processor before flashing.
