What are you talking about ? I didn't say you had to launch anything from your smartphone. Delete all the connections from your 3ds,start tethering with your phone, connect both your laptop and your 3ds to the mobile hotspot, start the cfw, use wireless Network watcher to get your console ip, then modify the run.bat and execute it (from your pc of course)
Oh! I thought you meant to run the .bat file from the folder with the required files from smartphone. I'm totally new to this 3DS hacking stuff. I'm sorry for the confusion. Thanks!
