@stephen dumma Clear Kodi's data, don't worry about an entire factory reset.
If you have the original T8 or T8-S device: Go to the launcher's homescreen. Click the Settings icon (normally one or two cogs). Click the "Other" tab. Click the More Settings button. Select the Apps entry. Scroll down to Kodi (or DBMC (DroidBOX Media Centre) or SPMC, whichever you installed Titanium into and click on it. Select Force Stop if not greyed out and confirm. Select Clear Data and confirm.
If a T8-S Plus v1, T8-S Plus v2, T8 Mini device: Go to the launcher's homescreen. Click the Settings icon (normally one or two cogs). Select the Apps entry. Scroll across to Kodi (or DBMC (DroidBOX Media Centre) or SPMC, whichever you installed Titanium into) and click on it. Select Force Stop if not greyed out and confirm. Select Clear Data and confirm.
It might be worth checking if the Wizard you're using requires a certain version of Kodi (16,17 Jarvis,Krypton). If it does, once the data has been cleared, open the app and click on the System Info entry, under the System menu. If you have a T8 or T8-S, Kodi 16.1 and DBMC 16.3.0 are the latest compatible versions. If the Wizard requires 17/Krypton, switch to a different build/wizard.
