This device uses MR3E module which needs to be replaced with an ESP. Besides the module, this process will require a heat gun, soldering tools and moderate soldering skill.

You need a size 2.0 triangle bit to open the case. The screws are under rubber stoppers, a fine screwdriver or needle pulls them out. In addition, the underside is clipped in.

Successfully opened you can remove the existing MR3E and replace with an ESP-12.
