Attempting to restore always fails (error 4013)
I disconnected every single sensor, only left battery and dock (USB) port sensors connected.
My device by default already always goes into "Recovery Mode". From there using iTunes or 3UTools, as soon as I select a firmware or backup and click on "Restore" system boots into "installing update/firmware mode", I see the spinning wheel for 2-3 seconds and then system boots back again into Recovery Mode and obviously no update gets installed and nothing works. What am I missing?
Is this a good question?
