I have an old apple watch that was stored for a long time, now it doesn’t turn on, it gets stuck in a beating apple logo when connected, support sais there is no solution but a paid replacement. I found on internet an iBUS cable that claims to be a way to enter DFU mode so you are able to apply a full restore from the OS image. Do you know if it is real and if it works?
Yes, the iBus tool is what you will need to enter into DFU mode.
