I'm glad for you man
I never planed or thought about unrooting, it may be easy to do that.
you can see the code of the .cmd file by opening blackjack with 7-zip.
good to know
: because of NSIS limitations, the process starts with a timeout delay of 13 seconds for letting enough time to the exploit to run. Because psneuter can't kill adb by itself, it needs an external intervention. So, 13 secs after having launched blackjack, it will send a command to kill adb, whatever is happening. That's why daemon starts a second time right after the exploit.
So, if you have firewall/AV which detects an adb connexion for 127.0.0.1, allow it
. If it is done too late, you'll have to restart blackjack because of the delay !
