Title: The Dreaded "Re-Partition Operation Failed" in Odin: Causes, Fixes, and Prevention

For Samsung Galaxy device users, Odin is both a blessing and a curse. It is the official gateway to manually updating firmware, unbricking a soft-bricked phone, and installing custom binaries. However, it is also a source of anxiety. Few error messages induce panic quite like the bright red text: ":failed" or, more specifically, "Re-Partition operation failed."

If you are staring at this message, do not unplug your phone just yet. While serious, this error is often solvable with the right files and patience.

Here is an in-depth look at why this error happens and how you can fix it.

6) Step-by-step fix sequence (recommended order)

Reboot PC and device.
Install latest Samsung USB drivers; run Odin as Administrator.
Use original USB cable; plug into PC rear USB 2.0 port.
Confirm device model and download exact official firmware (matching model and region).
Extract firmware package; do NOT use any PIT unless required.
In Odin:
- Load files into their appropriate slots: BL, AP, CP, CSC (use HOME_CSC to preserve data or CSC to factory reset).
- Leave “Re-Partition” unchecked.
- Ensure “Auto Reboot” and “F. Reset Time” are checked.
Boot device to Download mode and connect. Odin should show a COM port.
Start flash. If it succeeds, device will reboot.
If Odin reports “re-partition operation failed. odin”:
- Disconnect and retry steps 3–8 with a different USB port/cable and different Odin version.
- Try using HOME_CSC vs CSC variants.
- Try flashing only AP (or single-file firmware) first.
If still failing and you were instructed to repartition (rare):

Obtain the exact PIT file for your model.
In Odin, load PIT and check “Re-Partition”. Proceed only if PIT is verified to match model.

If error persists after correct PIT and firmware, stop and seek service: likely hardware partition table corruption or bootloader lock that requires manufacturer service.

Step 6: Advanced Troubleshooting

If the above steps fail to resolve the issue, you may need to:

Perform a factory reset: This will erase all data on the device, so ensure you have a backup.
Use a different Odin version or a third-party tool: Some users have reported success with alternative tools like Heimdall or SP Flash Tool.

Conclusion

The "Re-partition operation failed" error in Odin can be a challenging issue to overcome, but it is not insurmountable. By understanding the causes of this error and following the troubleshooting steps outlined in this guide, you should be able to resolve the issue and successfully flash firmware on your Samsung device.

The "re-partition operation failed" error in Odin is a common issue that occurs when the software tries to reallocate the partition table on a Samsung device and fails. This often happens because the PIT (Partition Information Table) file is missing or the "Re-Partition" box is checked without the necessary files loaded. Here is how you can troubleshoot and fix this error: 1. Disable the Re-Partition Option

By default, the "Re-Partition" option in Odin's Options tab should be unchecked. If you accidentally checked it without a PIT file, the process will fail immediately.

Action: Go to the "Options" tab in Odin, uncheck "Re-Partition," and try flashing again using only the standard BL, AP, CP, and CSC files. 2. Use a PIT File

If your phone's partition table is corrupted (often indicated by an "Invalid PIT" or "PIT not found" error alongside the re-partition failure), you actually do need to re-partition. re-partition operation failed. odin

Action: You must obtain the correct .pit file for your exact model and region. In Odin, go to the PIT tab, upload the file, and ensure "Re-Partition" is checked this time.

Note: Using the wrong PIT file can permanently brick your device, so verify your model number (e.g., SM-G991B) carefully before proceeding. 3. Change USB Ports and Cables

Odin is extremely sensitive to connection stability. A minor drop in data transfer can cause the re-partition command to fail.

Action: Use the original Samsung USB cable if possible. Avoid using USB hubs; plug the cable directly into a USB 2.0 port on the back of your PC (motherboard ports) rather than front-panel ports. 4. Check Firmware Compatibility

Flashing the wrong firmware version or a build from a different region can cause partition mismatches.

Action: Ensure you are using the latest firmware from reliable sources like Sammobile or SamFw. Match your model number and "CSC" code exactly. 5. Update Odin Version

Older versions of Odin may not handle the partition tables of newer Samsung devices correctly.

Action: Download the latest version of Odin (currently v3.14.4 or higher is recommended for most modern devices) and run it as an Administrator.

Possible Reasons for Failure:

Insufficient Battery: Ensure your device has a sufficient charge. Some operations may fail if the battery is too low.
Corrupted Files: The files you're trying to use for the re-partition (like .pit, .tar.md5 files) might be corrupted. Download them again and verify their integrity.
Incorrect Files or Operations: Make sure you're using the correct files for your specific device model and that you're performing the correct operation. Incorrect operations or files can lead to failures.
USB Connection Issues: A faulty or unstable USB connection can interrupt the process. Try using a different USB port or cable.
Device Issues: Hardware problems with your device, such as a faulty storage, can cause re-partitioning to fail.
Odin Version: Using an outdated version of Odin might not support certain operations or may have bugs that have been fixed in later versions.

8) When to stop and get professional help

Multiple failed repartition attempts with correct firmware/PIT.
Device stuck in bootloop after partial flash.
Hardware-level errors (e.g., inability to enter Download mode reliably, repeated disconnects).
Carrier-locked or warranty-covered device—visit authorized service to avoid further damage.

What Does “re-partition operation failed” Actually Mean?

To understand the error, you need to understand the “Re-Partition” checkbox in Odin.

What it does: When checked, Odin tries to rewrite the PIT file (Partition Information Table). This is the map telling your phone where the system, cache, user data, and recovery partitions live.
Why it fails: Odin can’t find a valid PIT file to flash, OR the PIT file you provided doesn’t match your device’s hardware, OR (most common) you accidentally checked “Re-Partition” without supplying a PIT file at all.

The #1 cause: Forgetting to uncheck “Re-Partition” after a previous flash attempt. Odin sometimes leaves it enabled by default.

2) Safety checklist (do these before trying fixes)

Charge device to ≥50%.
Use the official firmware for your exact model (model number and region).
Backup important data (flashing/repartitioning can wipe it).
Use a Windows PC with administrative rights.
Download latest Samsung USB drivers.
Use the official/compatible Odin version (see step 6).

5.1 Precautionary Steps

Use original Samsung USB cable and a USB 2.0 port (not USB 3.0).
Run Odin as Administrator (Windows).
Disable antivirus and Samsung USB drivers’ “power saving”.
