If you have tried all the above and continue to receive the error, the issue might be a hardware failure on the iPhone motherboard itself (e.g., faulty NAND memory), which prevents writing new data.

The error occurs when using 3uTools (a third-party iOS management utility) during firmware flashing, jailbreaking, or system recovery processes. iBEC (Intermediate Bootloader Ecosystem Chip) is a critical low-level bootloader component on Apple devices (specifically A5–A11 chips). Failure to write to iBEC typically halts the procedure, leaving the device in a recovery loop or DFU mode.
