I have a Sony A7ii Camera and recently I formatted a new memory card on my camera and the battery was around 40%. During the format process, the camera turned off and when I tried restarting it again, it won't show any firmware in the camera and would just flicker once with the live view display and then go black.
I have been trying to solve this problem and have no success till now. Please help out if any of you have any idea how to get this fixed.
