I just broke a Four wire connector in step Four or Five.. To replace the lcd wasnt a Big deal.. Now the MacBook runs again perfectly, just the Sdcard doesnt work.. i think because of the broken connector.. Thanks to IFixit to have my MacBook Pro back!,
Be careful to disconnect the different connectors!!
