I've used Heimdall 1.4.0 on my mac to install CWM 188.8.131.52 (file name:
recovery-clockwork-184.108.40.206-n7100) on my Samsung Note 2 GT-N7100 with android 4.3, the installation went smooth with no issues.
I then booted in recovery mode (volume up, home, power) and installed the zip file containing superuser downloaded from the link on the google play.
I then booted my phone normally, and tried if it was rooted with root checker, installed via google play. It says it's not rooted.
the application superuser starts and gives no errors,
I've done the procedure several times, also installing supersu, and installing other versions of CWM but I always got the same result.
What could I possibly have done wrong? and how can I finally get to root my phone?
