Bricked Prime during update last night HELP!!

[Michael de Estrada]

Have you tried reformating the internal storage ? Simultaneously hold down C F O then On, and the calculator will boot into its utility setup mode. Select option 4. FLS Utility, then 3. Format Disk C. When done, back out and select 9. Reset, and the calculator will reboot into its normal mode.

This might not help, but the only harm will be the loss of all your programs and data.
