Re-partition: Operation Failed. Odin
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.
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.
Are you trying to fix a specific error like "PIT not found," or did this happen during a standard firmware update?
When the "Re-Partition operation failed" error occurs in Samsung Odin , it typically indicates that the software cannot find or access the device's Partition Information Table (PIT)
. This table tells the phone how to divide its internal storage into system, data, and cache sections. Common Causes & Solutions Missing PIT File
: If you have the "Re-Partition" box checked but haven't provided a file, the operation will fail. : Extract the file from the
binary of your firmware or download the specific PIT file for your device model and load it into the Corrupted Firmware Files
: Corrupt or incorrect firmware binaries often cause this crash. re-partition operation failed. odin
: Re-download the firmware from a reliable source and verify the MD5/SHA256 checksums to ensure file integrity. Physical Connection Issues
: A loose USB cable, a faulty port, or an outdated Odin version can disrupt the partition process.
: Use the original Samsung USB cable, try a different USB port (preferably on the back of a PC), and ensure you are using the latest version of Odin Locked Bootloader
: On many U.S. Samsung models (especially those with Snapdragon processors), the bootloader is permanently locked, preventing re-partitioning or flashing custom software. Step-by-Step Recovery Process Exit Download Mode : If stuck, force a restart by holding Volume Down + Power for about 7–10 seconds. Flash Without Re-Partition : Most standard firmware updates do
require re-partitioning. Try flashing again with the "Re-Partition" option Use Full Repair Firmware
: If the partition table is truly broken, look for "4-file" (BL, AP, CP, and CSC) repair firmware. Use the ) to perform a clean wipe and re-partition. : Messing with partitions is risky and can permanently brick your device . Always back up your data before attempting these steps. Are you trying to recover a bricked device or just performing a standard firmware update
The "Re-Partition operation failed" error in Odin is a critical signal that the software is unable to properly write the Partition Information Table (PIT) to your Samsung device. This often results in a "soft brick" where the phone is stuck in Download Mode. Common Causes
Incorrect PIT File: Using a PIT file that does not match your specific model and storage capacity.
Locked Bootloader: Attempting to re-partition or flash unauthorized files on a device with a locked bootloader.
Hardware Failure: In severe cases, this error indicates a dying eMMC (internal storage) chip that can no longer be written to.
Connection Issues: A faulty USB cable or port can interrupt the NAND write process. Troubleshooting Steps To resolve this error, follow these steps in order:
Switch USB Ports and Cables: Use an original Samsung USB cable and connect it to a direct motherboard port (not a hub).
Flash Full Stock Firmware (4-File): Download the correct firmware for your exact model number. Load all four files—BL, AP, CP, and CSC—into Odin. Using the full CSC file (not HOME_CSC) often contains the necessary PIT information to fix the partition.
Disable "Re-Partition": Ensure the "Re-Partition" box is unticked in Odin's options unless you have a standalone .pit file and a specific reason to use it.
Update Samsung Drivers: Ensure you have the latest Samsung USB Drivers installed on your PC.
Use the Latest Odin Version: Older versions of Odin may not support the partition structure of newer Samsung devices.

The "Re-Partition operation failed" error in Odin typically occurs when the software tries to modify the device's partition table but lacks the necessary instruction file (PIT) or the correct firmware files. Common Causes
Missing PIT File: The Re-Partition option was checked in Odin's settings, but no Partition Information Table (.pit) file was provided.
Incorrect Firmware: Flashing firmware meant for a different model or storage capacity (e.g., trying to flash 256GB firmware on a 128GB device).
Corrupted Connection: Use of a poor-quality USB cable, a faulty USB port, or outdated Samsung USB drivers.
Outdated Odin Version: Older versions of Odin may not be compatible with newer Samsung device partitions. How to Fix the Error
Uncheck Re-Partition: Unless you are explicitly trying to fix a corrupted partition table, uncheck the "Re-Partition" box in the Odin Options tab. Most standard firmware flashes do not require this.
Use the Correct PIT File: If re-partitioning is necessary, you must load the specific .pit file for your exact model and storage capacity into the PIT tab in Odin.
Flash Full Stock Firmware: Download the complete 4-file firmware (BL, AP, CP, and CSC) from reliable sources like SamMobile or SamFW. BL: Bootloader AP: System/Kernel CP: Modem/Radio CSC: Country/Region-specific settings
Try a Different USB Setup: Switch to an original Samsung USB cable and use a motherboard USB port (on the back of a PC) rather than a front panel or hub.
Run as Administrator: Right-click the Odin executable and select Run as Administrator to ensure it has the necessary system permissions.
Force Reboot to Download Mode: If stuck, hold Volume Down + Power (and Home/Bixby if applicable) to exit and then re-enter Download Mode before trying again.
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.
Why Did the Operation Fail?
The "Re-Partition operation failed" error usually stems from one of three specific scenarios:
Final Verdict
The “re-partition operation failed” error is terrifying to look at, but it’s almost always a checkbox mistake, not a hardware disaster. Why Did the Operation Fail
TL;DR – Go into Odin, uncheck “Re-Partition,” and flash again. You’ll probably be booting into Android within two minutes.

MEMORANDUM
TO: Central Systems Architecture / Chief Engineering Officer FROM: J. Sterling, Lead Systems Analyst DATE: October 14, 2024 SUBJECT: CRITICAL FAILURE: Re-partition operation failed. odin
1. Executive Summary
At approximately 03:14 hours UTC, the scheduled maintenance window for the primary archival cluster (Designation: ODIN) commenced with the objective of extending the primary storage partition (/dev/mapper/odin-vol0) to utilize newly provisioned NVMe blocks. The operation was intended to be a routine logical extension, facilitating the ingestion of the Q4 historical datasets.
The operation failed catastrophically.
The re-partitioning utility exited with a fatal error code (0x0000FATAL: INTEGRITY_MISMATCH), leaving the volume in a suspended and unreadable state. As of 05:00 hours, the ODIN cluster is offline, and all dependent services—including the Deep-Search Index and the Customer Heritage Vaults—are currently inaccessible.
2. Technical Chronology of Failure
The following is a reconstructed timeline based on the system logs retrieved from the buffer moments before the crash:
- 03:14:12 UTC: Initiation of
gdiskutility on primary drive/dev/sda. - 03:14:15 UTC: Verification of GPT header integrity. Status: OK.
- 03:14:20 UTC: Deletion of legacy partition table entries to accommodate new sector boundaries.
- 03:14:22 UTC: ANOMALY DETECTED. The system flagged a conflict in the Logical Volume Manager (LVM) metadata. The new partition size (32TB) exceeded the maximum trackable sectors defined in the legacy ODIN kernel driver.
- 03:14:24 UTC: The operation attempted to write the new GPT table.
- 03:15:01 UTC: FAILURE. The write operation hung for 37 seconds before the I/O controller threw a timeout exception. The error message logged was:
ERROR: Cannot write physical volume. Device 'odin-core' is busy or corrupt. - 03:15:03 UTC: The filesystem driver attempted to remount the volume to preserve data. This failed due to the corrupted partition table. The system entered kernel panic mode.
- 03:16:00 UTC: ODIN dropped offline.
3. Root Cause Analysis
Initial diagnostics suggest the failure was precipitated by a "Bit-Rot" scenario in the underlying filesystem structures. While the re-partition command was syntactically correct, the drive's firmware reported bad sectors at the precise boundary where the new partition was to be written.
It appears the diagnostic pre-flight checks did not adequately scan the physical health of the target sectors before attempting the metadata rewrite. When the utility attempted to force the write, it created a logical paradox: the partition table claimed the space existed, but the drive controller refused to acknowledge it. This corrupted the Master Boot Record (MBR) and the GPT backup header simultaneously.
We are currently dealing with a "Zombie Partition"—the drive spins, the light blinks, but the logical addressing is entirely scrambled.
4. Impact Assessment
The fallout from this failure is severe.
- Data Availability: 100% of the data residing on the ODIN logical volume is currently unreachable. We do not believe the data is "lost" in the sense of being overwritten, but it is currently invisible to the operating system.
- Service Disruption: All client-facing APIs requesting historical data are returning 503 Service Unavailable errors. The load balancer is attempting to reroute traffic to the backup cluster (Designation: THOR), but THOR is currently only 48% synchronized with ODIN, meaning roughly half of all requests for archival material will fail.
- Operational Risk: Any attempt to force a repair using
fsckortestdiskcarries a significant risk of irreversible data deletion
Step 2: Check and Prepare Device Storage
- Free up internal storage space by deleting unnecessary files, apps, or data.
- Ensure that the device has sufficient battery charge (at least 50%) before attempting to flash firmware.
Step 1: Uncheck “Re-Partition” (The Most Likely Fix)
- Open Odin.
- Look at the Options tab.
- UNCHECK the box next to “Re-Partition.”
- Ensure “Auto Reboot” and “F. Reset Time” are the only boxes checked.
- Load your stock firmware (BL, AP, CP, CSC) again and flash.
Result: This works for 70% of users. The error disappears instantly.
