Solved! I had downloaded the image make available by @mefistos from this URL: MEGA ;next,I copied the image with the ‘dd if=/mnt/usb/mycloud.img of=/dev/sdx’ instruction…next I had made 40 seconds reset with the my cloud without power cable, after 40 seconds I connect the power cable press and hold reset.
The mycloud is come back with blue led and reachble from dashboard.
Next I had made complete factory reset to erase all data from mefisto’s image and clean the disk.
Thank you to all!
