I apologize, for all those who could not undo and could not connect and put the firmware, I fell ill, but I'm feeling better, and one day later when I'm better I'll be able to write a letter to everyone and install the firmware. I beg you not to create panic. everything will be fine.
Whoever could not install the firmware, I ask you to wait 1-2 days, I'll personally install you.
once again a pardon of forgiveness for the delay.
Regards.
