It's up to date, these errors arrive after the installation indicates "success", ignore them.I updated to this via twrp v7.0. All appeared ok (flashing bar progressed to full) except towards the end of the install, some partitions could not be mounted and listed in red but I couldn't remember exactly which partitions. Then screen came back to the twrp UI. Then i went ahead to reboot to system then it prompted me "No OS was installed. Proceed to reboot?". I went ahead and reboot.
The About Phone in Settings is now showing 14.0.10.0, the latest stable rom
So did i install it successfully?
