Ok thx it worked, but I still can't root.Yes.
I have tried the solution here with flashing the bootinsecure.img and all but that didn't work. Now I have tried with CWM 220.127.116.11 and installing the newest supersu (v2.37) but when I boot I don't have root. Is this because I have tdb enabled? Lollipop is installed on system 1 so should work right?
When I reboot afterwards cwm does say root may be lost and ask if it should try fixing it or not, which doesn't seem normal to me...
It's finally working, thanks for the help
All I have to do now is find out how I change the menu button to show the recent app switcher. I've changed 139 MENU to 139 APP_SWITCH but all that did was break the power button
