Hello everyone, guys, help me restore Pico_Max, I messed up something with the firmware, now when connecting via USB the LEDs do not light up, and in the device manager it is seen as an incomprehensible device for which I cannot find drivers. Is there a chance to fix it and return Pico to the factory state and the ability to run firmware from MicroSD.

I think it is caused by you not installing the corresponding driver, please refer to our wiki .erasing -spi-nand-flash
and create SD card

No, my friend, that's not the issue, and I installed the driver. I have a second Pico_Max and it always blinks the LED when power is supplied, but the faulty one doesn't blink. And it doesn't boot from a working micro sd with a working system, which boots normally on the third-party Pico_Max

Hello, LED does not flash means that it has not entered the kernel loading stage, if you can boot the system in another SD card can not make this problem Pico_Max start may be hardware damage, PC can also identify Rockusb Device Description bootrom and DDR is able to run normally, if there is a serial debugging tool, then provide a bit after inserting SD card after power-on printed content, you can easily find out where the problem is

We provide an image on the network disk at https://wiki.luckfox.com/Luckfox-Pico/Download/ , where you can also perform flashing and testing.
