Abstract

The embodiment of the invention discloses a method and device for writing an IMEI (International Mobile Equipment Identity) and a mobile terminal, and is applied to the technical field of communications. The method comprises the steps of: setting a read-write mode of a target nonvolatile memory as a read-only mode; carrying out authentication on a coding tool; if passing the authentication, setting the read-write mode of the target nonvolatile memory as a writable mode; receiving an IMEI to be written and a coding instruction which are sent by the coding tool; and according to the coding instruction, writing the IMEI to be written into the target nonvolatile memory. Therefore, by setting the read-write mode of the target nonvolatile memory as the read-only mode and carrying out authentication on the third-party coding tool, a case that the IMEI is randomly tampered by an unauthorized third-party tool can be effectively prevented, so that a conflict caused if different mobile phones have the same IMEI is avoided, and the mobile phones can normally access the network of an operator to achieve a normal call function.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a method, a device and a mobile terminal for writing an international mobile equipment identification code. Background technique [0002] International Mobile Equipment Identity (IMEI, International Mobile Equipment Identity) is an electronic serial number consisting of 15 or 17 digits. Every mobile phone is given a unique IMEI code. The IMEI code can be used to query warranty or production information. [0003] In the prior art, whether it is a Qualcomm platform or a MediaTek (MTK, MediaTek) platform, the way IMEI is written into a mobile phone is open, so it is easy to be cracked, and the IMEI code can be tampered with at will through a third-party writing tool. If the mobile phone has the same IMEI code and the IMEI code verification is required in the registration operator's network, it will affect the mobile phone's access to the operator's network, which will affe...
