Repartition Operation — Failed Odin

The Partition Information Table (PIT) tells Odin where to write data. If this is missing or the "Re-partition" box is checked without a file provided, Odin panics. Bad Connection:

A loose USB cable, a dusty charging port, or using a USB 3.0/3.1 port (which Odin sometimes dislikes) can cause the data stream to drop. Wrong Firmware:

You might be trying to flash firmware meant for a different model variant (e.g., trying to put T-Mobile software on an international model). Locked Bootloader:

If "OEM Unlock" wasn't enabled or "Find My Mobile" (FRP) is active, the device will reject the re-partition command for security. How to fix it The "CS" File Trick:

Most modern Samsung firmware comes in a zip with five files (BL, AP, CP, CSC, and HOME_CSC). If you use the

file (not HOME_CSC), it often contains the necessary PIT information to automatically re-map the partitions. Swap Cables and Ports:

Use an original Samsung cable if possible. Switch from a USB 3.0 (blue) port to a USB 2.0 (black) port on your computer, as they are more stable for flashing. Run as Administrator:

Ensure Odin is running with full system permissions on Windows. Manual PIT Flash:

If the standard flash keeps failing, you may need to download the specific

file for your exact model and load it into the "PIT" tab in Odin.

This is a high-risk move that can hard-brick your phone if the file is wrong. When it’s bad news

If you have tried multiple cables, different versions of Odin, and the correct PIT file but still get the error, it often points to a hardware failure

of the internal NAND (flash memory) chip. If the chip has become "read-only" due to age or damage, it cannot be re-partitioned. Do you have the exact model number of the phone and the firmware version you're trying to flash? repartition operation failed odin

Fixing the "Repartition Operation Failed" Error in Odin: A Complete Guide

If you’ve ever tried to flash a custom ROM or restore your Samsung device to its factory firmware, you’ve likely encountered the "Repartition Operation Failed" error in Odin. This message is a major roadblock, often leaving your device stuck in a boot loop or on the "Emergency Recovery" screen.

The good news? It’s usually a software or configuration issue rather than a hardware death sentence. Here is everything you need to know to fix it. What Causes the "Repartition Operation Failed" Error?

Odin triggers this error when it attempts to change the partition structure of your phone’s internal storage but fails to gain the necessary permissions or access. Common culprits include:

Missing PIT File: The Partition Information Table (PIT) tells Odin exactly where each piece of data should go. If you check "Re-partition" without providing a PIT file, Odin fails.

Corrupted Firmware: The firmware files (BL, AP, CP, CSC) might be incomplete or mismatched for your specific model.

Faulty USB Connection: A loose cable or a USB 3.0/3.1 port (which Odin sometimes dislikes) can interrupt the process.

Locked Bootloader: If your "OEM Unlock" or "FRP Lock" is enabled, the device will reject any attempts to re-partition the storage. Phase 1: The Quick Fixes (Try These First)

Before diving into complex partitioning, rule out the simple hardware glitches:

Switch USB Ports: Use a USB 2.0 port if possible. USB 3.0 ports are known to cause communication "hiccups" with Odin.

Use the Original Cable: Samsung devices are notoriously picky about cables. Ensure you are using an OEM high-quality data cable.

Run Odin as Administrator: Right-click the Odin .exe and select "Run as Administrator" to ensure it has full system permissions. Phase 2: The PIT File Solution (The Real Fix) The Partition Information Table (PIT) tells Odin where

In 90% of cases, this error happens because you checked the "Re-partition" box in the Options tab but didn't provide a PIT file. How to fix it:

Extract the PIT file: Most modern Samsung firmware (the 4-file "binary" firmware) actually has the PIT file hidden inside the CSC file. Download your firmware and extract the zip.

Use a tool like 7-Zip to open the file starting with CSC_***.

Inside, look for a file ending in .pit and extract it to your desktop.

Load it into Odin: In Odin, go to the Pit tab (next to Options). A warning will pop up; click OK. Load your extracted .pit file here.

Flash Again: Go back to the Log/Options tab, ensure Auto Reboot, F. Reset Time, and Re-partition are checked. Load your BL, AP, CP, and CSC files as usual and hit Start. Phase 3: Disable FRP and OEM Lock

If the operation fails immediately, your phone’s security might be blocking the write command.

Boot your phone (if possible) and go to Settings > Developer Options. Ensure OEM Unlocking is toggled ON. Ensure USB Debugging is toggled ON.

If your phone is stuck on a screen saying "FRP Lock: ON," you must flash the exact same version of the official firmware that was previously on the device without checking "Re-partition." Phase 4: Use "CSC" Instead of "HOME_CSC"

When you download Samsung firmware, you often get two CSC files. HOME_CSC: Keeps your data but does not change partitions. CSC: Wipes your data and re-partitions the phone.

If you are getting the "Repartition Operation Failed" error while using HOME_CSC, switch to the CSC file. This will factory reset your device, but it is often necessary to clear the partition conflict. Summary Checklist

Odin Version: Use Odin v3.14.4 or newer for recent Samsung models. Understanding the Error When you flash a Samsung

Drivers: Ensure the latest Samsung USB Drivers are installed.

Firmware: Verify your model number (e.g., SM-G973F) matches the firmware exactly.

If you’ve tried a PIT file, a new cable, and the correct firmware and it still fails, the internal NAND flash memory may be physically damaged. However, for most users, simply matching the PIT file to the firmware solves the problem instantly.

Understanding the Error

When you flash a Samsung device, you are writing data to specific partitions on the internal storage (e.g., AP, BL, CP, CSC).

Repartitioning means changing the size or structure of these storage partitions.
The Fail: Odin throws this error when it tries to write to a partition that doesn't exist, is the wrong size, or when the "PIT" file (Partition Information Table) doesn't align with the firmware files.

Top Causes (From Most to Least Common)

8. Example Recovery Walkthrough (Concise)

Scenario: Repartition failed with metadata showing new partition P3 but /dev/sdb has no corresponding partition.

odinctl metadata export --file /root/odin-backup.json
odinctl operations list -> op-12345 (state: in-progress)
odinctl operations resume op-12345
- If resume fails, odinctl operations rollback op-12345
Check /dev/sdb with parted; recreate partition with exact start/end from metadata if missing:
- parted /dev/sdb mkpart primary 102400MiB 204800MiB
partprobe /dev/sdb; odinctl metadata verify
fsck -n /dev/odin/P3; mount read-only; validate contents
Remove maintenance mode, bring into service, monitor.

Method 4: Disable "Re-Partition" (Safe Mode Flash)

If you are flashing the exact same firmware version or an update (not a downgrade or region change), you should not be repartitioning at all.

Load your firmware files in Odin.
Go to the Options tab.
UNCHECK the box that says "Re-Partition".
Make sure F.Reset Time is checked and Auto Reboot is checked.
Click Start.

Repartition Operation Failed: Diagnosis and Recovery for Odin-Based Storage Systems

Part 2: The Immediate Symptoms

Before fixing the error, confirm you are seeing the correct one. In Odin’s message box (the bottom-left panel), you will see something like:

<ID:0/005> Set PIT file..
<ID:0/005> DO NOT TURN OFF TARGET!!
<ID:0/005> FAIL!
<ID:0/005> Repartition operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)

On your phone’s screen, you might see:

"SW REV. CHECK FAIL"
"SECURE CHECK FAIL : (PIT)"
A static "Download mode" screen with a red or blue line
"An error has occurred while updating the device software"

The phone is now in a soft brick state — it won't boot into Android, but Download Mode is still accessible.

5. Bad USB connection or faulty cable

Believe it or not, a simple CRC error during the PIT transmission can cause the phone to reject the repartition command. This is the easiest fix to attempt first.

5. Corrupted Firmware or USB/PC Issues

A bad download, wrong model firmware, unstable USB cable, or using USB 3.0 ports (prefer USB 2.0) can cause intermittent repartition failures.
