3. tips

Do not use the "Format All + Download" option when flash firmware with MTK SP flash tool.

when the wire flashing process is interrupted, the machine may enter a fake dead state, and the mtk spflashtool does not recognize the port. The machine needs to be completely powered off or powerless before it can be reset.
