I have a problem much like yours only that I deleted my SystemUI.apk and System Res and can't event load the Bootloop. So I talked to technician and ask if what's the best thing we can do about my problem and he said that the only sure way to resolve this is to get the Asus Memopad 8 Firmware.
Unfortunately, the Asus MemoPad 8 Firmware is still not available not until a couple more months. So I guess our only option is to wait until an official firmware for our tab and other support drivers are available for download online.
I'm still have problem..
