Description
Technical Field
The embodiment of the invention relates to a machine brushing technology, in particular to equipment to be brushed, a connector and a machine brushing system.
Background
The high pass 9008 mode is called Qualcomm HS-USB QDloader9008, is a download mode, and is an online mode of the bottom layer of the high pass platform. The 9008 download is a direct flash of all partitions in the system using the 9008 port of the highpass chip. The 9008 flush mode is more bottom-level, efficient, powerful, and does not require access to any partition of the system. So the application is very common.
Current devices that use high-pass chips typically enter 9008 mode by a combination of a power-on key and a +/-volume key. Due to the limitation of the structure and software, the technical scheme often has the problem that the flash mode cannot be quickly entered because the power-on key and the volume key are not unnecessarily combined for use.
