Repartition Operation Failed Odin «5000+ FREE»

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 repartition operation failed odin

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 The Partition Information Table (PIT) tells Odin where

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? Find the Correct PIT File: Search online for

4. Using a PIT file from a different carrier/model

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).

Method 6: Bootloader Version Mismatch – Accept the Upgrade or Downgrade

If the error includes "SW REV CHECK FAIL" in the phone screen, your bootloader is newer than the firmware. Solution: You cannot downgrade. Download the newest firmware available for your model (check bootloader version on SamMobile). Flash that instead.

To check your current bootloader without booting: Enter Download Mode → look for "RP SWREV" or "B:5" (meaning version 5).

Part 2: Common Causes of the Failure

There are three primary reasons why this specific error occurs:

Method 1: The "PIT" File Fix (Most Common Solution)

If you are flashing a different firmware version (e.g., changing from a carrier firmware to an unlocked firmware), the partition layouts often differ. You need to map the partitions manually using a PIT file.

1. Find the Correct PIT File: Search online for the PIT file specific to your device model number (e.g., SM-G991B.pit). There are databases like SamMobile or FirmwareScience where these can be found.
2. Load the PIT File in Odin:
   • Open Odin.
   • Click the "PIT" tab (you may need to click "Options" or look for the tab depending on your Odin version).
   • Select the .pit file you downloaded.
3. Re-Flash:
   • Load your firmware files (BL, AP, CP, CSC).
   • Crucial: Ensure the "Re-Partition" checkbox is CHECKED in Odin options.
   • Click Start.

Note: Re-partitioning wipes the device completely. Ensure you have a backup if possible.
