"Possible root access lost" error in Clockwork Recovery

[thegadgeteur]

Flashed my friend's Nexus 7 (old model) with Clockwork and now whenever doing a full ROM backup, when you select reboot it warns that "root access may be lost". This has happened 6-7 times and each time everything has ended up being fine. Help?

You can try to download ROM Manager. See if there is an update for CWM. If there is, accept, let it flash, and reboot into recovery. When you reboot the system, it may prompt for the fix, scroll to it, and click yes.
