Can I use CWM recovery made for KitKat in Lollipop?
I had a similar issue in the past, it could be that Lollipop is preventing the recovery from root access, it is disabled by default.

Go to settings -> developer options -> root access. Enable the option for apps &amp; adb.

If you can't see the developer options go to settings -> about phone. Then tap on the build number section 10 times (it works as a hidden button)
