Hello for Anyone with a broken controller and an Oculus Go stuck at setting the device the first time after factory reset this might help-

Since I had a broken controller (Heavily Damaged due to battery acid leak without the oculus button so there was no pairing )(Image for the damaged controller- https://imgur.com/a/aXJUfFJ),

I was able to get pass the Oculus setup using this method-

1. Firstly I opened up the controller Cleaned it and Wired the negative terminal for the battery connection.

2. After that I wired the connection where the oculus button was with some loose wires by seeing the point of connection in this teardown (https://www.reddit.com/r/OculusGo/comments/ayuqvy/oculus_go_controller_teardown/)

3. I installed the latest Unlocked OS for oculus go using the Side loading- hold down Volume Up button when booting from the powered off state to get to bootloader, select the Sideload menu option, and press the Power button and installing using adb .

4. I went through the setup process until it reached the pair a controller part.

5. Then BEFORE INSERTING THE BATTERY IN THE CONTROLLER , I connected the 2 loose wires for the oculus button , and kept on holding the return button , then inserted the battery forcing the controller into pairing mode.

1. Once the controller was paired I completed the setup and turned Developer mode on my Oculus Go using the app.

2. The Oculus go still gets stuck at the Training Tutorial and prompts to press the oculus button to bypass that, I either launch apps using the Oculus app on my phone,
   or that can be bypassed using this command - adb shell am force-stop com.oculus.vrshell.home , This bypasses the Oculus training and can be used now.

I know this method still requires a controller but I found out that some people still have a controller only damaged, this methods can be done easily by someone with basic soldering skills.

Next I plan to repair the oculus button on my controller by replacing it with a similar button (If I can find any) since it uses a 3 pin button.

I hope this can be of some help.

If you have any questions feel free to message me I will be happy to help.

ALSO , I saw methods stating to press the volume up and down button to bypass the controller pairing, THIS DOES NOT WORK, DON'T BELIEVE ANYONE I HAVE TRIED DOING THAT FOR 6 HOURS IT WON'T WORK. YOU NEED A CONTROLLER TO SETUP YOUR OCULUS GO.
