When you check this box and flash a firmware package containing a .pit file (Partition Information Table), you are telling Odin to redraw the map of your phone’s internal storage. It deletes the old partition table and writes a new one, effectively telling the phone: "This is where the operating system lives, this is where the cache lives, and this is where the user data lives."

Download a tool like and open the CSC_xxx file from your firmware package.

This article provides a deep dive into why this error happens and, more importantly, how to fix it in 2026. What Causes "Re-partition Operation Failed" in Odin?

The is one of the most frustrating roadblocks you can encounter when flashing official firmware or custom ROMs on a Samsung device. This error explicitly signals that the Odin flashing tool cannot map out or write to your device's internal storage layout. It essentially leaves your phone soft-bricked, often stuck in Download Mode or trapped in a boot loop. The device screen in Download Mode showed: When

Accidentally checking the "Re-Partition" box in Odin without providing a valid, matching .pit file, or using an unstable PIT file.

: Use a complete 4-file firmware package (BL, AP, CP, and CSC). Ensure the Samsung USB Drivers are up to date.

Re-partitioning is a low-level operation. If your USB cable is loose, the port is dirty, or the drivers on your Windows PC are conflicting, the transfer of the PIT file will be interrupted. Because the operation involves rewriting the partition table, any interruption causes Odin to abort the process immediately to prevent permanent bricking.

Odin is extremely sensitive to connection stability. A minor drop in data transfer can cause the re-partition command to fail.

| Practice | Reason | |----------|--------| | Never check “Re-Partition” manually unless you have a PIT file | Avoids accidental partition mismatch | | Always flash instead of CSC when upgrading | Prevents partition resize operations | | Before flashing custom ROM, backup PIT via Odin (PIT tab → Read PIT) | Enables recovery of original layout | | Avoid cross-region firmware (e.g., EUX on CHC) | Different region PIT may have different hidden partition sizes |
