Change of dob on my birth certificate

Consult a lawyer in India (Andhra or Telangana) Produce both the certificates i.e. hospital & SSC and file a petition for declaration for date of birth in civil courts. The court order is imporant at everywhere.

You need to check the hospital records where you born if its possible and you got record send it to municipal office for correction

Actually you don't need to change your DOB at all. The USCIS doesn't care what your other certificates including SSC, aadhaar or even passport say. They only care for the municipality certificate. So just include the municipality birth certificate and use the same DOB in the GC application. You'll be fine. By the way courts don't change your DOB on record at the municipality simply because you put another date on all the other records. You've been using the wrong DOB all along like many Indians. At least now start using the true one. You'll be just fine. Otherwise it'll be hard for you to get social security benefits when you apply for your citizenship and become a citizen along with other problems.
