[Asus Transformer TF700] sbdags:
You've just got so many errors I don't really know where to begin:

Examples:

This one is very common:

12-16 21:42:20.124 E/webcoreglue(3747): Should not happen: no rect-based-test nodes found

Which browser is this? Next Browser? I thought you were using stock?

12-16 21:36:20.714 E/InputDispatcher(546): channel '4153e2f8 com.jiubang.browser/com.jiubang.browser.main.BrowserActivity (server)' ~ Channel is unrecoverably broken and will be disposed!

If you want to run e2fsck do this:

Boot into TWRP

Go to advanced / mount and unmount data

go back to advanced / terminal just click ok on the browse folder bit (it doesn't matter) and type the following and hit enter

e2fsck -fvyD /dev/block/mmcblk0p8

A kill button will appear and disappear when it finishes. My guess is it will take a very long time to finish and you will have lots of errors. Bit let's see. You may want to plug it in.
