How to resume firmware update if it stops or freezes before finishing for iOS
Please follow the below steps if the firmware update freezes or stops when partially completed.
Ensure you have the most recent version of the PAI app.
If you're on app version "2.0.15" or higher, fully close all open apps and re-open. The app should complete the firmware update from where it stopped.
If you've unpaired from phone or forgotten the app, open the app and add SLICE in the settings page. Select "SLICE has DFU" and the firmware will complete from where it stopped.
If further issues arise repeat from step 2.
