So about 9 months ago, one of my AirPods 2 earbuds (the right one) stopped abruptly while listening to music. I've unpaired them with my phone and then it worked until a day later when it happened again. This time I've unpaired them from both my iPhone and MacBook, clicked "Forget this device", reseted the AirPods using the button on their case and then cleared them from my iCloud. After doing this I've let them outside the case to drain, case also opened to drain and then I charged everything up. After doing this, both AirPods worked for like some split seconds until the right one cut off again and no sound was heard after. So, I decided to do all those steps I did earlier.

Unfortunately, after doing this again, the Air Pods case flashes white for like 30 seconds - 1 minute, after which it turns to blinking green but without being paired to any of my devices or even being in my iCloud devices. My Macbook, Iphone or any other device doesn't recognise them.

When taking the right AirPod out of the case and leaving only the left one in, the gree blinking stops and it's only steady green, but again without being connected to something.

When taking the left AirPod out of the case and leaving only the right one in, the blinking color switches from green to red and it keeps on blinking until I put the left one in, but both the case and the Airpod are charged.

What is this behaviour and how can I fix it ? I don't have an Apple store in my country, only Apple Premium Resellers (iStyle) which are a bunch of morons that upcharge for everything.

Edit: by red color, I mean Amber/orange, they are not fake
