Прошивка nand без пайки Antminer L3+, D3, A3

Needed: NEEDLE, SD-card 16-2 GB.

If the L3 + board does not fully start, all 4 blue LEDs do not light up (of course, if the internal nand stick is not dead at all).
If the board does not boot or sew with a factory restore L3 + SD-card from Bitmain. We read the exact instructions after the purchase.
In case of failure, no claims will be accepted, go for it at your own peril and risk.
