Problems solved by technology

[0008] Among them, cracking the kernel code usually takes several weeks, which takes a long time, which in turn prolongs the cycle of transplanting ROM
Moreover, the work of cracking the kernel code is usually done by a fourth party, resulting in an uncontrollable progress of the process, making it impossible to predict the deadline for porting the ROM

Embodiment Construction

[0035] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0036] This embodiment performs ROM transplantation for the disassembled code of the mobile terminal, and the process takes several hours. Compared with the solution described in the background art that takes several weeks, the transplantation efficiency is greatly improved. Moreover, the transplanted object in this embodiment is the difference between the disassembled codes of the ROM to be transplanted and the original ROM, which simplifies the transplanted content and further improves the transplanted efficiency.

[0037] see figure 2 , the main method flow of transplanting ROM in the present embodiment is as follows:

[0038] Step 201: Obtain the kernel code o...

Abstract

The invention discloses a method and a device for transplanting a read-only memory (ROM) and is applicable to improvement of the transplanting efficiency of the ROM. The method comprises the following steps of: acquiring kernel codes of a mobile terminal; disassembling the kernel codes of the mobile terminal, and thus obtaining disassembling codes of the mobile terminal; transplanting different parts of the disassembling codes of the ROM to be transplanted and an original ROM to the disassembling codes of the mobile terminal, wherein the kernel codes of the original ROM and the mobile terminal are in the same system type; and assembling the transplanted disassembling codes of the mobile terminal. The invention also discloses the device for implementing the method.

Description

technical field [0001] The invention relates to the field of computer and embedded technology, in particular to a method and device for transplanting a ROM. Background technique [0002] With the development of communication technologies, mobile terminals have become one of the main communication tools for people. Moreover, with the improvement of the hardware performance of the mobile terminal, various value-added services added to the mobile terminal are becoming more and more abundant. Among them, the value-added service is usually developed by a third party other than the mobile terminal. Then the third party needs to transplant the developed ROM (Read Only Memory, read-only register) related to the value-added service to the mobile terminal system. [0003] Currently, the third-party ROM porting process is as follows, see figure 1 Shown: [0004] Step 101: Obtain the kernel code of the mobile terminal. [0005] Step 102: Crack the kernel code to obtain the original...
