Recovery options - when Slice will not boot
- 1 To reset working system/reset media library
- 2 If Slice boots all the way but then hangs or has corrupted text or library
- 3 If Slice boots to the 'Slice' or 'Kodi' screen and then hangs or halts with errors; or boot results in a flashing 'Kodi' logo
- 4 If Slice refuses to boot at all or shows errors immediately at startup
- 5 If the hard drive keeps 'disappearing'/becomes unmounted/media missing
To reset working system/reset media library
Goto: Setup -> OpenElec settings -> System -> Reset System Settings to defaults
This function deletes the /settings directory but does NOT wipe the recovery information or any media.
If Slice boots all the way but then hangs or has corrupted text or library
SSH into Slice - see Transferring media and networking guide#How to access Slice from another device
cd /storage rm -rf *.*

Remove power from Slice
Remove the dongle for the remote from its USB socket
Plug in a USB keyboard
Plug in power and press the <shift> key on the keyboard as it boots
Enter the recovery system - it should show a list of installed operating systems or simply <(Slice stable)>
Press and hold <Ctrl and Alt> and hit the <F2> key (Fn+F2 keys on Mac keyboards)

If Slice refuses to boot at all or shows errors immediately at startup
You will need to convert your Slice into a 'mass storage device' to access the eMMC drive. The Raspberry Pi team has published a page here which contains a Windows installer, as well as instructions if using Cygwin or Linux.
Note that if running Windows 8 or 10, the OS will not allow you to install unsigned drivers. The page here gives a temporary workaround to allow the eMMC drivers to be installed.
Download and run the program - this will install the eMMC drivers
Plug the USB cable into Slice and the computer
'Safely eject' the Slice hard drive in Windows
Plug the power adaptor into Slice (keep the USB connected)
Windows will find the eMMC drivers and (part)install
Goto Device Manager (use Windows search box if necessary)
The device (BCM2835) may have a yellow mark next to it
Right-click on device name
Click <Driver> tab
Click <Update Driver>
Select <Browse my computer>
Select <Let me pick from a list...>
Select <Device (BCM2835)>
Back out of Device Manager
In the Windows search box, type:
Run the program. After a few seconds the eMMC will pop up in Windows as a disk (USB mass storage device)
You will now be able to access the eMMC as an 'external' drive. Folders such as RECOVERY should be present on the disk.
Download a copy of NOOBS software from: http://updates.fiveninjas.com/slice/noobs.zip
Unzip it and copy the files onto the first partition (they should overwrite the files already there)
IMPORTANT - 'safely eject' the eMMC drive before unplugging!
Unplug the power cable from Slice
Disconnect the USB cable from Slice, then reconnect it (this reboots the hard drive)
Check Slice's hard drive (where media is stored) by right-clicking on its icon
Select <Tools> tab
Select <Check> button
Wait for checking procedure to finish
If errors found, select <Repair>
IMPORTANT - 'safely eject' the drive!
Remove the USB cable from Slice
Insert power into Slice
Press the Ninja button on remote (or Shift key on keyboard)
Select the Stable build
Follow the on-screen instructions
Slice should now boot up normally. NOTE - Slice will be back to its 'factory' state.
If the hard drive keeps 'disappearing'/becomes unmounted/media missing
Update to the latest 'stable build' - click here  for instructions.
Power down Slice.
Plug it into a pc using the USB cable WITHOUT the PSU connected. In Windows, check for and then repair any errors.
IMPORTANT - 'safely eject' the drive in Windows and then disconnect as usual.
ALWAYS 'safely eject' the drive after using in Windows;
ALWAYS <power down> the Slice before removing the PSU.
If the above does not work:
Repartition and reformat the drive using NTFS (if Windows). See here  for instructions.
