Where did you get your Update? From the Updater application?
Also are you using a SD that is formatted as internal storage?
Go over to this topic and download the newest version (1.5.4) of the Updater application.
You now need to install it on your tablet. The easiest way is to download it directly from the forum to your tablet and then open it via the File Manager on your tablet.
Then retry to install the update.
If the newer Updater doesn't help to fix your issue please go into your Downloads File and delete the OTA (Update File).
Then proceed to download it again with your Updater application.
These 2 points are the most likely solutions to your problem.
