LIke @michaelkenward says, keep trying. tftp is time sensitive for several steps. I've seen several times when it was the 3rd/4th time when it worked for people
And you have to have tftp enabled on your computer. did you enable it?
I don't know how it suppose to work actually, being in reboot state means the router is not active to estiblish a connection to it so that you can install a new frameware
What I can see that the device has a hardware failure that can't work any more.

Reboot state? That's not solid amber. That's better described as "corrupted state".
The point of the various steps involved in TFTP is that does establish a connection between the laptop and the router. (Disconnect everything else from the router.) The trouble is that the connection may not last long for some reason. You have to get in there and do the TFTP stuff while there is a connection.
As @plemans suggests, a video is a good way of seeing how to go about things.
One thing that hasn't come up before is the faint chance that you can force the thing into recovery mode.
Press reset for 30 seconds
Keep pressing reset while removing power
Keep pressing reset for another 30 seconds while apply power
If that works the power LED may start blinking white and you may be able to use TFTP to write new firmware to the thing.
Remember to set the IP address on the laptop before you do any of this, and restore the default after you have finished messing around. Then the laptop will get its IP address from the router.
"Reboot state? That's not solid amber. That's better described as "corrupted state"." --> This is on the Manual of WifiExtender 3700 (Power Point in solid Amber means the extender is rebooting)

I can see the TFTP is a great way to manually install a new frameware to thw router but you need the router to be active to be able to connect to it and push the new changes.
As @plemans suggests, a video is a good way of seeing how to go about things. --> I watched the video already to do the steps but on the video, the router power led was blanking which means it was responding not solid amber as in my state

--> I tried that and it didn't succeed as well

--> I did that as well because I was following the steps on the video
I totally appreciate your suggestion and that you are trying to help me out but I am afraid nothing from the above help me fix the issue of my extender and I think I will buy another but I will choose a different brand
The problem is that we are trying to fix an extender, I made the mistake of reading where you posted your message.
At the outset I should have advised you to put your problem in the appropriate section. This discussion shows why this is important. Different devices have different issues and ways of doing things.
This section is for Nighthawk WiFi Routers. The chances of success are higher if you take your problem to where it belongs:
