OTA non-inductive flashing method, flashing system and electronic equipment

The invention discloses an OTA non-inductive flashing method and system and electronic equipment, and the method comprises the steps: obtaining the transmission progress of a previous data transmission period according to a stored transmission progress flag bit in response to a data transmission request sent by an OTA terminal, and feeding back the transmission progress to the OTA terminal; the OTA terminal obtains target upgrading data from the OTA server based on the transmission progress, and synchronously sends a self-defined service request when receiving the target upgrading data; in response to a user-defined service request sent by the OTA terminal, executing backup area data clearing, and feeding back a service response to the OTA terminal so as to trigger synchronous transmission of the target upgrade data; and verifying the received target upgrade data, feeding back a data transmission response to the OTA terminal according to a verification result, and updating a transmission progress flag bit.
