I follow the google web page about the VIM3L fastboot step.
After Try ALL DAY…
It always not response during the super.img.
Although I use the USB port on the back of the computer motherboard for power and even replace the 3 adapter. It’s still not work.
I’ve never seen this happen in other development board.
update the new super.img fastboot result.
It sill random no response.
I found the reason.
Fastboot’s continuous writing will cause the chipset temperature to rise.
If the temperature of the chipset exceeds 40 degrees,fastboot will crash.
I put the board in the fridge while I use fastboot now.
