Help/Support IDA/GDB issue code inject crash ,help
Curtain replied to Curtain's topic in Help & Support
I think the problem has been solved. Registers can only be modified when debugging, and can not be made into a patch switch. -

@@DiDA please locked -
let me see e ... 0xA99C0 CMP R0, R10 //compare R10 with R0 0xA99C4 BLE 0xA99E8 //branch to 0xA99E8 if it is less than or equal to if R10 less or eq R0,then branch to 0xA99E8.. so why you wrote 0xA99F8 is it wrong ?

Help/Support IDA/GDB issue code inject crash ,help
Curtain replied to Curtain's topic in Help & Support
yes,i think so because i learned code inject tut from DIDA/airmax etc they always found offset /funtion/data then done such as : offset:0xaddress STR R4, [R6,#0x98] ----------->STR R7, [R6,#0x98] tweak like this:writeData(0xoffset, 0xhex) because once run ,app will crash ___________________________________________________ if i want to change register value,(set $r4=0xhex or set $r4=$r7) which is my offset and hex for make a patcher. i am so sorry for pool english. -

Curtain replied to Curtain's topic in Help & Support
i set $r4=0x99999 only whether "$r4=0x999" or "$r4=$r7" how converted to just like [0xoffset,0xhex] in this way ,make a patcher. -
