Re-partition Operation Failed. Odin ⟶ 〈PRO〉

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Corrupted Connection: Use of a poor-quality USB cable, a faulty USB port, or outdated Samsung USB drivers.

Outdated Odin Version: Older versions of Odin may not be compatible with newer Samsung device partitions.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.

Fix 6: Flash Stock Firmware Using Heimdall (Mac/Linux Alternative)

Sometimes Odin is the problem. Heimdall is an open-source cross-platform flashing tool that gives more verbose error reporting.

How to fix:

• Install Heimdall suite.
• Extract your firmware to .img files.
• Use: heimdall flash --RECOVERY recovery.img --SYSTEM system.img --CACHE cache.img --no-reboot

If Heimdall fails at the same point, it confirms a hardware/NAND issue. re-partition operation failed. odin

Fix 1: Uncheck "Re-Partition" in Odin

This is the #1 cause of the error. By default, Odin enables "Re-Partition" if it detects a PIT file in the same folder as the firmware. For standard stock firmware flashes, you do not need re-partitioning.

How to fix:

• Open Odin (version 3.13.1 or 3.14.4 recommended).
• Look at the Options tab.
• Uncheck the box labeled "Re-Partition".
• Ensure only "Auto Reboot" and "F. Reset Time" are checked.
• Flash again.

Note: Only check "Re-Partition" if you are explicitly flashing a PIT file to convert storage (e.g., changing from 64GB to 128GB layout, or after a full NAND corruption). For normal firmware updates, leave it unchecked.

Fix 2: Use the Correct CSC

If you are manually loading files into Odin (BL, AP, CP, CSC):

• Ensure you load the CSC file (usually named CSC_xxx.tar.md5).
• Do not load HOME_CSC_xxx.tar.md5 when attempting a Re-Partition.

Conclusion

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.

The error message "re-partition operation failed" in Odin typically occurs when the tool cannot correctly write the Partition Information Table (PIT) to your Samsung device. This often indicates a mismatch between the firmware and the device's partition layout, or a physical issue with the phone's NAND flash memory. Understanding the Error

When you flash firmware using Odin, the tool uses a PIT file—a "map" that tells the software where each segment of data (like system, boot, and recovery) should go. If the "Re-Partition" option is checked but no valid PIT file is provided, or if the provided PIT doesn't match your specific hardware model, Odin will halt the process to prevent permanent damage. Common Causes

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. The "Re-Partition operation failed" error in Odin typically

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.

: 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

: 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.
