Yes I tried this already. But it didn't work. Because all these tools want you to hold the c-button. But with c-button my phone/pc doesn't react. And with 2&5 it says the following things:

Code:
ChipID:C802,EMP protocol:0401
BOOTROM MODE DETECTED
can't get NET header
can't load ACCESS CPU preloader
Can't load ID loader !
