Quadcopter Unstable/Unflyable

I've spend two days researching on what the issue is and a day trying to tune my ESCs and now I am at a loss, Please help.

Initially I had an issue with a single twitching motor. I solved it by re-soldering the connections and synchronizing the ESCs. Now that is fixed Another issue came about. Whenever I try to lift off the quadcopter keeps flipping, sometimes the motors are inconsistent and keep pulsating instead of steady power.

Here are the things I have confirmed multiple times.

1. soldering is good. (I'm not professional tho)
2. Motors and Props are spinning in proper direction.
3. ESCs are synchronized using Blheli
4. Using betaflight the controller was told that yaw is at 180 degrees. The USB port is facing west on a NAZE 32.

At this point I am at a loss as to what is going on. Please help.

My setup is
FC: NAZE 32
ESC: racester RS20A 4 in 1 ESC
Motors: DLFPV 2300KV brushless motor
Receiver: FlySky FS-i6B
 
There's an arrow on your board that shows orientation, it should be pointing forward. If not which way is it pointing?
 
I had the same problem a while back,
I checked everything & was all OK the only thing I didn't try was a board & gyro reset. It was the board reset that worked. So try what RENOV8R said to me.
Providing the rest of the setup is correct.
 
Did you match the esc firmware to what is on the configuration tab in betaflight or vice versa.
In other words if you are using multishot on the esc's, then apply that in the configuration tab. Top right corner.

I reset the board but it did not solve the issue, if anything it made it worse. How do I reset the Gyro? I tried looking through your old posts but was not able to find the one you're referencing.
 
Does the quad image in the setup tab move the same way you move the model?
Do the signals and movements in the receiver tab match your inputs?

I tried that and put Yaw at 0 in the software. It did not fix the issue. I though that it can face anyway as long as I tell it in the software. Since it is pointing towards the back I put yaw at 180 degrees. The arrow is on top which I think is the correct way.
 
So after extensive research I found that someone had similar issues due to how they ran the wiring. Something with the wiring was disturbing the gyroscope.

I have reorganized my wiring and it works fine now. No soldering was needed either.

Thank you all.
