USB downloader device for Samsung smart phone

This device is used to easily open the download mode of any Samsung smart phone. It is easy to make at your home. You can visit my YouTube channel for more details.

Always you should mind resistance value should have around 302 - 303 k ohm.

Here I have used 270 & 33 k ohm resistors

At first join two resistors then join them with 2nd & 4th pin of mini USB port. Then insert into any Samsung android phone

* This device is only for SAMSUNG smart phones only , it couldn't work in other company phones.

After inserting it you will see downloading mode will come.
