Repartition | Operation Failed Odin

Scenario: Repartition failed with metadata showing new partition P3 but /dev/sdb has no corresponding partition.

  • Check /dev/sdb with parted; recreate partition with exact start/end from metadata if missing:
  • partprobe /dev/sdb; odinctl metadata verify
  • fsck -n /dev/odin/P3; mount read-only; validate contents
  • Remove maintenance mode, bring into service, monitor.

    • Odins versions 3.12 and above sometimes enable Re-Partition by mistake if they detect a PIT file.
    Solution:

    If the firmware was correct for your phone, this solves the problem 50% of the time.

    Newer Samsung devices use dynamic partitions or have hidden system/vendor partitions. Flashing an old firmware over a new bootloader — or vice versa — can confuse the partition scheme.

    If you are reading this, you have likely been staring at a red or blue progress bar in Odin that suddenly stopped, followed by a dreaded message in the log box: "Repartition operation failed." repartition operation failed odin

    You might have tried to unbrick your Samsung Galaxy device, downgrade Android, or fix a bootloop. Instead, you are now stuck with a phone displaying "An error has occurred while updating the device software," and a computer screen full of error codes.

    This is one of the most frustrating errors in Samsung firmware flashing. But don't panic. In 80% of cases, the "Repartition operation failed" error is reversible, and your device is not permanently bricked.

    This article will explain exactly what this error means, why it happens, and provide you with 7 proven solutions to fix it.

    If you are flashing the exact same firmware version or an update (not a downgrade or region change), you should not be repartitioning at all. Check /dev/sdb with parted; recreate partition with exact

    When Odin flashes firmware, it doesn’t just copy files — it can also rewrite the partition table (PIT file), defining where system, cache, user data, and other partitions live on the eMMC storage. The repartition operation fails when Odin cannot correctly rewrite this table.

    In plain English: Odin tried to change the map of your phone’s internal storage, but the phone rejected the new map.
