A forced downloading device and a method for entering a forced downloading mode

Abstract

The invention discloses a forced downloading device and a method for entering a forced downloading mode. The forced downloading device comprises an electrode and a forced downloading switch. The electrode comprises a positive electrode, a data positive electrode, a data negative electrode and a negative electrode; The two ends of the forced downloading switch are connected with the positive electrode and the negative electrode of the data respectively, and the forced downloading switch controls the positive electrode and the negative electrode of the data to be short-circuited, so that the intelligent terminal enters a forced downloading mode. Under the condition that the intelligent terminal is not disassembled, the forced downloading switch is used for controlling whether the positive electrode and the negative electrode of the data are short-circuited or not, so that the intelligent terminal enters a forced downloading mode, the intelligent terminal can be prevented from being damaged, the intelligent terminal can rapidly enter the forced downloading mode, time and cost are saved, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of data transmission, in particular to a forced download device and a method for entering a forced download mode. Background technique [0002] With the continuous development of science and technology, smart terminals developed based on the Qualcomm platform have increasingly become an indispensable part of people's lives. Due to the inevitable failure and incompatibility of smart terminals in the process of research and development and use. At present, the scope of use of smart terminals is becoming wider and wider and more and more users are using them. Therefore, how to minimize the processing workload for the problems of smart terminals has become one of the aspects that smart terminal manufacturers pay attention to. one. [0003] Whether it is a faulty machine that occurs during the research and development process of the manufacturer, or a faulty machine that is repaired by the user through after-sa...

AI Technical Summary

Problems solved by technology

[0003] Whether it is a faulty machine that occurs during the research and development process of the manufacturer, or a faulty machine that is repaired by the user through after-sales service, among these faulty smart terminals, there are a certain number of faulty machines that can be solved by upgrading the system program or downloading specific software. Most of the machines cannot be turned on normally or download software. If technicians or maintenance personnel want to upgrade the system program or download software for these machines, they must make the faulty smart terminal enter the forced download mode.

[0004] For the current smart terminal products, the manufacturer does not have an interface to enter the forced download mode in the state of the whole machine out of security considerations when designing. To enter this forced download mode, the technician must first short-circuit the smart terminal. Corresponding test points on the terminal board

[0005] However, these test points exist inside the smart terminal and cannot be directly accessed by users. At present, smart terminals are generally designed to be thin, and a lot of glue is inevitably used to replace the original buckles and screws. It is very difficult to disassemble the whole machine

At the same time, the dismantling process often causes damage to the casing or parts, which not only wastes time but also causes increased costs and user dissatisfaction.
