Repartition Operation Failed Odin -
Flashing a SM-G950F with a SM-G950U1 PIT file will trigger an immediate "Repartition operation failed" because the partition sizes differ (e.g., different modem partitions for CDMA vs GSM).
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.
Not all Odins handle repartitioning equally.
Try all three. Many users report that v3.10.7 bypasses the error where v3.14.4 fails.
The "Repartition operation failed" error in Odin looks like a catastrophe, but it is almost always a logical issue — a wrong checkbox, a mismatched PIT, or a driver glitch. Unless you hear a "click of death" from your phone (very rare), software solutions will prevail.
Start with Method 1 (uncheck Re-Partition), then escalate to Method 7 (Smart Switch). Between those two, 9 out of 10 users will see the green "PASS!" screen again.
If you have tried every method above and the error persists, post your Odin log and phone’s Download Mode screen (photo) on XDA-Developers or Reddit’s r/GalaxyNote series. Include your device model, current firmware version, and the attempted firmware. The community will likely spot the mismatch you have missed.
Remember: "Repartition operation failed" is not a death sentence. It’s just Samsung’s way of saying: "Stop. You are trying to restructure my memory incorrectly. Fix your files." repartition operation failed odin
Good luck, and may your Odin logs always end with PASS!
Troubleshooting "Re-Partition Operation Failed" in Odin Getting a "Re-Partition operation failed" error in Odin can be stressful, as it often suggests your Samsung device's partition table is corrupted or inaccessible. This usually happens when you try to flash firmware with the "Re-Partition" option checked but haven't provided the necessary PIT (Partition Information Table) Why Is This Error Happening? Missing PIT File:
You checked "Re-Partition" in the Options tab but didn't load a file in the PIT tab. Corrupted Firmware:
The firmware files you're using might be incomplete or the wrong version for your specific model. Connection Issues:
A bad USB cable or port can cause the write process to fail mid-way. Locked Bootloader:
Some Samsung devices (especially US Snapdragon models) have locked bootloaders that block re-partitioning. Hardware Failure:
In rare cases, this error points to a failing eMMC (internal storage) chip. How to Fix the Error 1. The "Quick Fix": Uncheck Re-Partition Most firmware updates do not require re-partitioning. tab in Odin. Re-Partition Try flashing your firmware (BL, AP, CP, and CSC) again. 2. The "Deep Fix": Use a PIT File
If your partition table is truly corrupted, you must manually provide the layout instructions via a PIT file. Download the correct PIT file Flashing a SM-G950F with a SM-G950U1 PIT file
specifically for your device model and storage capacity (e.g., SM-G973F 128GB). Using the wrong file can hard-brick your device. In Odin, go to the (usually a separate tab next to Options). Options tab Re-Partition Load your firmware files (BL, AP, CP, CSC) and click 3. Verify Hardware and Drivers Use the original cable:
Use a high-quality USB cable and a port directly on your motherboard (avoid USB hubs). Update Drivers: Ensure you have the latest Samsung USB Drivers installed on your PC. Try a different Odin version: Some older devices work better with Odin 3.13.1 or even older versions like 1.85. Summary Table: Error Scenarios
The "Re-Partition operation failed" error in Odin typically occurs when the tool attempts to rewrite the device's Partition Information Table (PIT) but cannot establish a stable connection or secure authorization to do so Core Causes of Failure Missing or Mismatched PIT File
: Odin often fails if the "Re-Partition" box is checked but no valid
(specific to your exact model and storage capacity) is provided. Secure Check Fail
: Modern Samsung devices with locked bootloaders may reject re-partition attempts as a security measure, resulting in a SECURE CHECK FAIL: (PIT) Firmware Downgrade
: Attempting to flash a firmware version with a lower binary level than what is currently on the device often triggers partition errors. Hardware Degradation
: In older devices, this error can indicate a failing NAND flash chip or EMMC health issues, where the storage can no longer be rewritten. Proven Solutions Avoid Manual Re-Partitioning Try all three
: In most standard flashing or rooting scenarios, the "Re-Partition" option should remain Flash Full Firmware (4-File)
: Instead of a single AP file, use the full firmware set (BL, AP, CP, and CSC) from reputable sources like . Using the file (rather than
) will trigger a clean wipe that often resolves partition table conflicts. Use a Correct PIT File
: If you must re-partition (e.g., due to a corrupted table), extract the PIT file from your firmware's CSC binary or download the exact one for your model. Add it under the in Odin while the "Re-Partition" option is enabled. Hardware Connection
: Ensure you are using an original Samsung USB cable and a rear USB port on your PC to prevent data transmission drops during the sensitive NAND write phase. Summary Table: Odin Flash Troubleshooting
This paper analyzes causes, detection methods, and recovery procedures for repartition operation failures in Odin-based storage systems. We categorize failure modes (software, hardware, metadata corruption, resource constraints), present diagnostic steps, propose automated and manual recovery workflows, and outline best practices to prevent recurrence. Practical examples and command sequences are provided for administrators.
There are three primary reasons why this specific error occurs:
Sometimes, Windows Defender or third-party antivirus software blocks Odin from writing partition tables, interpreting the action as malicious.
