Yes I did it cause the other on from e/ was not evn working to.
Should I start from 0 again?
I have uninstall the adb fastboot now again. And now I try to open from the file platform-tools the adb and adb devices and it says that bash : /usr/bin/ad no such file or directory
I have just found how to do it :
1.Extract the zip of the adb/fastboot in home
2.write in terminal :
cd platform-tools
sudo install adb /usr/bin/adb
sudo install fastboot /usr/bin/fastboot
And you will be able to use the last update of adb/fastboot tools
