I downloaded SDcard (EXT4), which is 8MB. When unzip it to .img file it is 125MB.

I upload this file to MV1000’s via uboot. Pls note mv1000 uboot LED status is a little different. But when press and hold for several seconds, power and wifi led light up and it enters uboot failsafe mode.

The file upload in around 20 seconds. Just wait. It flashes and reboot very quickly.

LAN and WAN works normally.
