others from using their app for dynamic debugging. After several rounds of dynamic debugging experiments, it was found that the Android application would call the function pthread_create to create the thread to reverse debug. Therefore, directly in the function java_com_yaotong_crackme_mainactivity_securitycheck at the breakpoint implementation of the method can not be directly achieved. Therefore, in order to prevent the anti-debugging of the app, the code of the program is modified. , locate

address, R5 is the kernel file of the beginning of the address. Check to see if the address is conflicting. The R5 equals R2 so that the decompress kernel address is after the 64K stack. (9) the function Decompress_kernel () that calls the file misc.c, extracts the kernel at the end of the cache (R2 address). At this point the Register values change as follows: R0 is the size of the kernel after decompression R4 is the address when kernel is executed R5 is the starting address for kernel after

...... A Vy = v2 ...... B is determined by virtual disconnection. If there is no current flowing through the input end of the Op Amplifier, R1, R2, and R3 can be considered as series connections. The current through each resistor is the same, and the current I = (VX-Vy) /R2 ...... C: Vo1-Vo2 = I * (R1 + r2 + R3) = (VX-Vy) (R1 + r2 + R3)/R2 ...... D. It is determined by virtual disconnection that the current flowing through R6 is equal to the current flowing through
