- | + | or you can reflash whole firmware (Windows) or restore just initfs part (Linux). Both initfs restoration steps are a bit risky and can cause data loss if something goes wrong so it may be good idea to simply live with the message until you decide to upgrade to next firmware or want to reflash whole device anyway. It does not slow down device booting or do any other harm. | |
