 **Solution:** 
 
 1. To automatically get into the flashing mode, you have to connect a **10 uF** capacitor between the **EN** and **GND** pins. This capacitor value could be lower (> 2.2 uF) if you don't have this part available. **EN <----||---- GND.** *(The capacitor can be electrolytic, ceramic, or tantalum. Using lower values like 2.2uF and 4.7 uF is also possible in most cases.)*
