Re-partition Operation Failed. Odin May 2026

The “Re-Partition operation failed” error is almost always software-induced – not a hardware failure. In 95% of cases, it resolves by using the correct 4-file firmware with HOME_CSC or manually providing the matching PIT file. Only rare eMMC logical damage requires JTAG repair. Users should never ignore this error by force-flashing without re-partition – that leads to boot loops or I/O mount failures.

The "Re-partition operation failed" error in Odin typically occurs when the software attempts to rewrite the device's Partition Information Table (PIT) but encounters a mismatch or connection issue. This is most often caused by using incorrect firmware for your specific model or neglecting to include a necessary PIT file when the "Re-Partition" box is checked. Quick Fixes to Try First

Uncheck "Re-Partition": In most standard flashing scenarios (like rooting or basic updates), the "Re-Partition" option should remain unchecked. Try flashing again with this setting disabled.

Switch USB Ports and Cables: Odin is extremely sensitive to connection quality. Use an original Samsung USB cable and a port directly on the motherboard (avoid USB hubs).

Run as Administrator: Ensure you are running the Odin Tool with administrative privileges on your Windows PC. Detailed Troubleshooting Guide 1. Verify Firmware and Binary Version re-partition operation failed. odin

Flashing the wrong region or an older binary version will trigger partition errors.

Match Your Model: Ensure the firmware exactly matches your model number (e.g., SM-G991B). You can find your model in Download Mode or via tools like SamFW.

Check Binary Level: Samsung prevents downgrading to older binary versions. Ensure the "Bit" or "Binary" number in your new firmware is equal to or higher than what is currently on the device. 2. Manually Flash the PIT File

If your partition table is corrupted, you must manually provide the PIT file to "repair" the storage layout.

Odin is extremely sensitive to USB instability. A poor connection during the repartition command will trigger immediate failure.

How to fix:

Odin output log displayed the following error message:

“Complete(Write) operation failed.”
“Re-Partition operation failed.”
“All threads completed. (succeed 0 / failed 1)” “Complete(Write) operation failed

The device screen in Download Mode showed:

“Custom Binary (PIT) Blocked by OEM” or
“Re-Partition failed – Unsupported version”

Many users download firmware from third-party aggregators. If the firmware is for a different region or a different model number (even one letter off), the partition layout will be wrong.
