This is the more serious hardware-related cause. NAND flash memory has a finite lifespan. Over years of flashing, wiping, and writing, some physical sectors (blocks) can go bad. When Odin attempts to write the new partition table, it might be writing to a bad block. The phone tries to remap it, fails, and reports the error.
Believe it or not, a bad USB 3.0 port can cause partition communication errors. Switch to a on the back of your computer. Also, use the original Samsung cable —off-brand cables drop data packets. re-partition operation failed. odin
Firmware files are massive. A partial download or a corrupted extraction from a ZIP archive can leave the PIT or TAR files with bad sectors. If Odin tries to read the PIT file to calculate partition sizes and encounters a checksum error or corrupt data, it will abort the operation to prevent bricking the device—ironically, leaving it bricked anyway. This is the more serious hardware-related cause

For newer Samsung phones (S10 and later), always use or newer. Older versions of Odin cannot handle the compressed .lz4 file system used in modern Samsung firmware, which often triggers a generic partition failure.
Do not panic. This error is almost always recoverable. This article will dissect precisely what "re-partition operation failed" means, why it happens, and provide a step-by-step guide to fix it.
By default, Odin leaves this box for standard firmware updates (BL, AP, CP, CSC). Most guides tell you to never touch that box unless you are specifically repartitioning a device with a PIT file.
