It seems that the update Show Box's authors made available most recently was broken. Head to Android's settings then click on Apps (if you can't see an Apps entry, click on the far right tab and then More or Advanced Settings first). Scroll down until you can see Show Box and click on it. If you see a button related to uninstalling updates, please click it.
If there isn't an option for that, click on Uninstall. Then open the ES File Explorer app, expand the Local menu situated on the left, and click on / Device. Now navigate to the System folder. If you can see a preinstall folder click on it. If not, e-mail us (
[email protected] ). Assuming you have just clicked on a preinstall folder, now look for com.tdo.showbox.SOMETHING.apk . If you can't see that, check for any file with Show Box in the title. Once found, click on it, and confirm you want to install it. If you're informed your security settings are too tight, click the Settings button, and allow installations from unknown sources.
After this, Show Box will be reinstalled, with a working version in place. When asked, deny the request to update.
This should keep you going until the authors release a fixed update.
