Hi friends
I had also bought an stm32f405 "supposedly" with possible update, using it only with its charger and software provided, after 6 months of use (without ever antivirus or web) the cable is is blocked

all the LEDs light up, when I do a firmware restore (provided by the seller) it reaches 100% flashing then indicates that it is blocked.
So i tried other older firmware , more recent... still blocked It also has the 8 pin chip on the back of the PCB, in short i think the only solution would be to encourage the king Badrax to help us keep the cables up to date. another STM32F405 but for how long will it be used ?
