I think I've explained correctly upto my knowledge.
Recently I recalibrated my battery since one of the Hex installers update messed up my battery life. it's only recommended when you see a sudden drop in the battery like from 20 % to 15 % or 90 % to 75% like that. Even though I didn't have such a serious draining issue I went forward and recalibrated the battery.
>you have to completely drain the battery ( turn of automatically) try to restart again until it won't turn on.
>plug into the charger and charger fully( for m30s it takes around 3 hours )
>unplug your charger and you can see 100 % on the screen and enter the code you mentioned above and hit 🆗
