I am still on Android 4.3 and have previously rooted my device. Trying to connect on a Windows 8.1 PC.
Recently I did a factory reset and now I get errors when setting up - "Unfortunately, Setup Wizard has stopped" - after the device name.
I am trying to unroot my device and upgrade to 4.4.2 but I cannot get the device recognised in download mode (power + volume down + home).
I have tried different USB cables, different ports and different PCs and the only difference is that all but one USB port shows the "device descriptor request failed" error in device manager. On one port I can see it when powered on and connected, and it is recognised in Kies and Odin. As soon as I put it in download mode I get an error and the device won't start and I get the "This device cannot start. (Code 10)" error.
I have nothing I need to get off the device, so am happy to try anything to get the device recognised so I can re-flash some firmware!
Any help would be most appreciated...
