Question

Electronics

For music, the receiver is cheap, it costs a standard password, there is an incident of unauthorized connection.
Can you really change the password?

Answer 1

Disassemble, determine the model of the microcontroller, find a programmer for it, read the firmware, carry out reverse engineering and find where the password is, change it, fill it back with a programmer.
A couple of months is quite realistic for you.
