Tried the methods in the first post & nothing happened. Then I tried this 'more aggressive' filesystem check/fix & it crashed! I couldn't boot at all. Kept restarting at the end of the boot animation. Trying a Nandroid restore now; nothing else seems to make it work.
Humm, 'nothing happened': specifically, which of the 'methods' did you try? they did not install? you received no output at all? Please explain.
The 'more aggressive' filesystems check was suggested to someone receiving a specific error. When did the crash you mention happen?
Did it crash while in recovery installing the 'update' or some other time? As stated above, it is possible that if you run the 'more aggressive'
check that files could be removed. Sounds like you did have some corruption on /data and as part of correcting that, it removed some files.
Also, those files being removed prevented the system from fully booting.
