– disconnect all other connectors (USB, PS/2, SW Power, Reset SW, P Led +/-), – remove the CPU cooler (you will need thermal paste later), – disconnect the power supply from the PC, – open the computer case, take a picture of the connections so you do not get lost later when you will have to reconnect everything. Each configuration presenting its own problems, its own flaws. This guide is for use in case of last resort, at your own risk. It is indicated on the forums that the black has a voltage too strong and can burn the motherboard, it’s false at least I did not see anything problematic in my case (desktop motherboard). There is no difference except the voltage of the black which can be more powerful, from 3.3V to 5V against 3.3V for the blue version. There are two versions of the mini SPI program: one black (the one I used, see image below), one blue. It will cost you between 5 and 25 dollars depending on whether you buy it from USA or from China of course with minimum 2 days transport time for USA and 1 month for China. It will save you between 100 and 800 dollars, ie the price of an old motherboard, or a recent computer if you prefer to buy everything. This hardware is the same used by the producers of motherboards, be it MSI, Asus, Asrock, Gigabyte … to unlock the cards when they are out of service, provided that they have not had a short circuit and that they did not burn.
