In Toyota website you have all instructions.

 Are you talking about Techstream? If yes, I tested on it and its working. Select Autel J2534 from TIS menu.

 Most of the OEM software you can download free. But even if you download the software from other website, you don't need to use crack. Use your username and password.

  the cracked tech stream version can not be used on line for flashing only for diagnostics and programming but you have to select your passthru by going to setup/vim select. sometimes this option is not available do to the software you used to crack the tech stream software which is not needed. to crack your tech stream simply go to c/program files/Toyota diagnostics/techstream/env/iT3 system scroll all the way down find available function, under that tis function =1 change it to tis function=0.  open your tech stream and your ready to go after that setting the passthru is available. go to programming and you will find your ecm/tcm and other modules calibration numbers before you buy a sub to make sure the flash will solve any issue. but again this cracked software can not be used on line to flash.pay the 55 dollars and their software is free.
