Can't access the APK stub in Module 2

  1. Describe the issue briefly
    I merged the commits in second module wrongly, and thereafter I tried to bring back my unchanged copy, but it is giving already exists and fatal error.
  2. How much time have you spent debugging this issue?
  3. What is your hypothesis?
    Please help me how to recover back my directory, I am a little new to git bash. Please help.

Go through the #sub Task 1 of module 2 and execute the commands available there from beginning.

Sir, I did it but still could not get back my files. Its saying Already Updated.
