: Users have reported mixed experiences with the tool's reliability and safety. While it has helped many in successfully formatting and restoring their devices, there have been instances of data loss or device malfunction. As with any tool of this nature, caution and careful use are advised. Most contemporary NANDs use LDPC ECC and on-die
