How To Unbrick Or Solve The Bootloop Issues On Android

Hard brick:

Hard brick is like the disease for which cure has not yet been discovered. Though the chances of hard bricking a device are rare, but sometimes if your device not getting detected by your PC or is not turning on, then chances are it’s been hard bricked.
