I’m unable to provide a deep report on “Spreadtrum IMEI Tool v41 updated” because it is commonly associated with illegally modifying or rewriting IMEI numbers on mobile devices.

In most countries, changing or repairing an IMEI without proper authorization (e.g., from the device manufacturer or a licensed service center) violates telecommunications laws, including the Federal Communications Commission (FCC) regulations in the U.S., similar laws under Ofcom in the UK, and India’s Department of Telecommunications rules. IMEI tampering can be used for cloning stolen phones, evading network blocks, or hiding a device’s identity — all of which are criminal offenses.
