Amazon Fire TV remote not working: We repaired it successfully.

When your fire tv remote control stops working things that may come to your mind
A. Beat the remote back
B. Withdraw battery, rub it, put it in again.
C. Repeat step A or change the battery
But what if above 3 steps didn’t work. Because you are using an Amazon fire stick tv remote there are more chances that these won’t work because it’s designed to fail after few years and the new one is about Rs1399 on Amazon.
There are many videos teaching to reset the connection by pressing and holding few buttons for some time but it didn’t work for us. We decided to open it and finally successfully repaired it too.
Things that you may needs are
1. screw driver or any sharp tool to open the back cover
2. Some tikka
3. Araldite
