Okay, finally home to try it !
So first problem (sorry ^^')
I do have adb on my android folder on my desktop but when I go to a terminal device I get
pc3:android hamzamechbal$ ./adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
So that's the good serial number but how do I get the online status ? Cause afterwards I get a error device is offline for the root steps...
Edit : I tried another adb file in the adb for mac guide and now instead of offline I get unauthorized -_-
Edit^2: Okay, I finally got the RSA authorization on the phone, so no more unauthorized problem. Back to the actual rooting.
Edit : Okay, so first step of pushing the file ok, then I type the second one (chmod 755), no response and when I try the third one I get
unable to open input and output for patching!
