Use GParted to expand the partition to use your entire SD Card. You will need at lease an 8GB card. The image is 4.7GB.

This is done for you now.
Just make sure your uEnv.txt looks like this after writing the IMG to the SD card but before you remove it from your computer.

console=ttyS0,115200n8
selinux=permissive
optargs=enforcing=0 cma=384M no_console_suspend
kernel_filename=kernel
initrd_filename=ramdisk.img
hardware=sun50iw1p1

# Uncomment to enable LCD screen
fdt_filename_prefix=pine64/sun50i-a64-lcd-

For those of you that don’t know how to write this IMG to an SD card…
You will need SD Formatter and Win32 Disk Imager.
win32diskimager
SD Formatter
Using SD formatter- Format your SD card with Option Format Size Adjustment enabled
Using win32diskimager – Write the IMG to the SD card
After the IMG hsa been written to the SD card, Open the SD card and edit the uEnv.txt to look like the section above. Insert the card in your Pine64 and power up. Make sure you are using a 5V 2A or larger power supply.

This is for the NXA116QC164. Not the 264 model. The 264 model has firmware updated to 6.0 on the nextbookusa.com site. Proceed at your own risk.

I bought an Ares 11 from Walmart and found out in short order that even though this tablet has good specs it is slow and with Android 5.1 installed it has a memory leak causing instability. After a bit of research I found that we can get root access, install a better recovery, downgrade to Android 5.0, and remove the encryption. After doing this, my tablet is much more responsive and stable. This also works for the Ares 8. Just use ares-8-boot.img instead of boot_noencrypt.img. everything else is the same.

This is just a more consolidated version of the information from HERE.

If you choose to continue following this tutorial, you acknowledge that performing these tasks may cause your tablet not to boot properly and that is your responsibility, not mine. All data on the tablet will be erased. You should backup anything you do not want to lose. With that being said, I have done this on two NextBook Ares 11’s without issue. So as long as you follow the instructions you should be fine.
