Even though the Samsung Galaxy S7 is magnificently powerful enough, still it is always a good idea to use unlocked device as it allows to use the device’s in best possible manner. And while we do try to achieve such access on our devices, sometimes it happens that we ended up having a bricked device that is no longer able to start properly.

Either it would get stuck between boot-loop or stuck a boot screen or in worst case it won’t be turned on. And with Android devices such incidences are becoming very common. As soon the issue is related with apps and operating system, it could be repaired using stock firmware and via performing resets over the device.
