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Corrupted Connection: Use of a poor-quality USB cable, a faulty USB port, or outdated Samsung USB drivers.
Outdated Odin Version: Older versions of Odin may not be compatible with newer Samsung device partitions.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.

There’s a special kind of dread that comes with seeing a red “FAIL!” box in Odin. You’re in the middle of reviving a bricked Samsung phone, and suddenly the log slaps you with the dreaded line:
“re-partition operation failed.”
The device disconnects. The progress bar freezes. Your heart sinks.
Don’t panic. This is a common Odin error, and in 90% of cases, your phone is not permanently bricked. More importantly, you didn’t break anything. You just told Odin to do something it shouldn’t have.
Let’s break down what this error actually means and how to fix it in three steps.
Odin is extremely sensitive to USB instability. A poor connection during the repartition command will trigger immediate failure. re-partition operation failed. odin
How to fix:
The "re-partition operation failed" error in Odin is intimidating, but in most cases, it is caused by a simple misconfiguration: forgetting to uncheck the Re-Partition box. Before assuming your phone is hard-bricked, work through the 12 fixes above. Start with unchecking Re-Partition, then move to cable and firmware verification.
If you reached Fix 12 without success, the device likely has a hardware-level NAND failure. At that point, professional repair or motherboard replacement is the only path forward.
For 95% of users, however, the solution is quick: uncheck the box, use a good USB 2.0 cable, and re-flash the correct firmware. Your Galaxy device will be back to life in minutes.

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-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 interruption that occurs when the software tries to modify the device's Partition Information Table (PIT) and fails
. This usually happens because the firmware files are mismatched, the PIT file is missing, or there is a hardware communication failure between the PC and the Samsung device. Core Causes of the Re-partition Failure Missing PIT File
: When the "Re-partition" option is checked in Odin, the program expects a specific
file to tell it exactly how to carve out the phone's internal storage. If you check this box but don't provide the file, the process will fail instantly. Firmware Mismatch
: Using firmware meant for a different model variant (e.g., trying to flash G991U firmware on a G991B device) often triggers a partition mismatch. Unstable Connection
: A faulty USB cable or port can interrupt the "Write" command at the exact moment Odin attempts to rewrite the partition table, leading to a "Complete(Write) operation failed" message. Locked Bootloader
: If OEM Unlocking is not enabled in Developer Options, the device may refuse to allow modifications to the partition structure as a security measure. Troubleshooting & Solutions 1. Disable the "Re-partition" Option
In most cases, you do not need to re-partition a device to flash standard firmware. Open Odin and go to the Re-partition
Retry flashing using the standard BL, AP, CP, and CSC files. Use the file if you want to keep data, or the file for a clean wipe. 2. Use a PIT File (The Direct Fix)
If your partition table is actually corrupted (often indicated by the phone being stuck in a "Download Mode" loop), you must provide the PIT file. Obtain the PIT
: You can extract this from a "4-file" (Binary Nature) firmware pack; it is often embedded in the file. Alternatively, search for your specific model's file on reputable forums like XDA Developers Load into Odin : Go to the in Odin, acknowledge the warning, and upload the file. Ensure the Re-partition box is now checked. 3. Refresh Hardware Connections
Communication errors are a leading cause of Odin "Write" failures. Change USB Ports
: Avoid USB 3.0 (blue) ports or front-panel case ports; use the USB 2.0 ports
on the back of the motherboard for the most stable power and data flow. Update Drivers : Reinstall the Samsung USB Drivers
to ensure the PC recognizes the device's interface correctly. Use the Original Cable If you are manually loading files into Odin
: Aftermarket cables often lack the shielding required for high-speed firmware flashing. 4. Version Compatibility
Using an outdated version of Odin with a newer Samsung device (like the S23 or S24 series) will frequently cause partition errors. Always use the latest version (e.g., Odin3 v3.14.4
) to ensure compatibility with newer storage technologies like UFS 3.1/4.0. Summary of Odin Tab Configurations Auto Reboot Reboots the phone automatically after a successful flash. F.

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.

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:
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.
If you are currently stuck, follow these steps to resolve the error:
Uncheck "Re-Partition": In the Odin "Options" tab, ensure the Re-Partition box is unchecked. Most standard updates do not require this.
Update Odin: Use the latest version (e.g., Odin v3.14.4 or newer) to ensure compatibility with modern Samsung partition structures like super.img. Conclusion The "Re-partition operation failed" error in Odin
Check Your Cable: Use an original Samsung USB cable and a high-speed USB 2.0/3.0 port directly on the motherboard.
Run as Administrator: Right-click the Odin executable and select Run as Administrator to ensure it has full access to system resources. 📂 Addressing Firmware Mismatches
Flashing the wrong files is the most common cause of this failure. 1. Match the Binary Version
You cannot downgrade to a lower binary version than what is currently on your phone.
Look for the S or U number in your firmware string (e.g., G973FXX**U3**ASG8). The digit following the "U" or "S" is the binary level.
Download the exact or higher binary version from reputable sources like SamFW. 2. Use the Correct PIT File
If you must re-partition (e.g., your partition table is corrupted), you need a PIT (Partition Information Table) file specific to your model.
For newer phones, the PIT file is often embedded within the CSC file (not the HOME_CSC).
If using a standalone PIT file, load it into the PIT tab in Odin. 3. Flash All Four Files
Instead of flashing a single file, use the full 4-file firmware set: BL: Bootloader AP: System/System Partition CP: Modem/Radio CSC: Regional customization (this will wipe your data). ⚠️ Potential Hardware Failure
If the error persists after trying different USB ports, cables, and correct firmware files, it may indicate a physical NAND (Internal Storage) failure.
This is common in older devices where the memory chip has reached its "read/write" limit.
If you see "NAND Write Start!!" followed immediately by "FAIL!", the motherboard likely needs professional repair or replacement. What version of Odin are you using? Can you copy and paste the Odin log text here? lt;ID:0/006> Re-Partition operation failed.
Re: Error by Flashing - Odin -
The "Re-Partition operation failed" error in Odin typically occurs when the tool attempts to modify the device's Partition Information Table (PIT) but cannot communicate correctly with the storage (NAND) or finds the table corrupted. It often happens because a user has checked the "Re-Partition" box without providing a matching PIT file, or because of hardware/connection instability. Common Causes
Missing PIT File: Checking "Re-Partition" in Odin settings without loading a .pit file in the "PIT" tab.
Hardware Connection: Unreliable USB cables (especially USB-C to USB-C) or front-panel USB ports on PCs often cause communication drops during critical partition operations.
Incompatible Firmware: Attempting to downgrade Android versions or using firmware with an older bootloader security level (Binary version) than what is currently on the device.
Corrupted PIT: The internal partition table on the phone is already damaged, preventing Odin from overwriting it.
Failing eMMC/UFS: In older devices, this can be a sign of physical NAND flash memory failure. Step-by-Step Solutions 1. Fix the Connection
Use a USB-A to USB-C Cable: Many users report that Samsung USB drivers perform better with a standard USB-A to USB-C cable plugged into a USB 2.0 port.
Rear Motherboard Ports: If using a desktop, plug the cable directly into the rear motherboard ports rather than the front case headers. 2. Use a Proper PIT File
If you must re-partition (e.g., to fix a boot loop or corrupted storage), you need the exact PIT file for your specific model and storage capacity.
Extract the PIT: PIT files are often found inside the CSC firmware file (not HOME_CSC). You can extract it using a tool like 7-Zip. Load into Odin: Open Odin and go to the PIT tab (ignore the warning popup). Load your specific .pit file.
In the Options tab, ensure Re-Partition, Auto Reboot, and F. Reset Time are checked. 3. Flash Full 4-File Firmware
Instead of flashing a single file, download the full "Service" firmware (BL, AP, CP, and CSC).
Use tools like SamFirm or Frija to download the latest firmware for your model.
Load all four files into their respective slots in Odin (BL, AP, CP, and CSC).
Crucial: If you use the CSC file (which wipes data), Odin may automatically handle partitioning. Do not manually check "Re-Partition" unless you are also loading a separate PIT file. 4. Update Drivers and Odin Ensure you have the latest Samsung USB Drivers installed.
Use a modern version of Odin (v3.13.1 or newer) for devices running Android 8.0 and above. Summary Table: When to Check "Re-Partition" Re-Partition Checkbox PIT File Required? Normal Update Fixing "Stuck at Logo" Changing Regions Rooting/Custom ROM No (usually)
