With Unisoc shifting to ARM’s TrustZone and hardware-backed secure elements, software-only tools like V4.1 are becoming obsolete. Newer Unisoc chips (T760, T820, T910) store IMEI in a one-time programmable (OTP) fuse. Once written at the factory, no software tool can change it.

What is Spreadtrum IMEI Tool V4.1?
It’s a third-party utility designed to rewrite, repair, or change the IMEI number on mobile devices powered by Spreadtrum (now Unisoc) processors. It’s often used when a phone loses its IMEI after a failed firmware flash, software corruption, or baseband damage.
Key Features (as advertised in modding communities):
Performance & Reliability:
Major Risks & Drawbacks:
Alternatives (legal & safer):
Final Verdict:
Avoid unless you are an experienced repair technician working on your own legacy device with documented IMEI loss — and you are fully aware of the legal and hardware risks.
