This thread is for Nextbook Ares 8 5.1.1
I don't have this device yet, @Conan1201 has offered to send me one, once I get it, I can begin the process of dumping the tablet, pulling the firmware, root, then TWRP.
What I would like is everyone that has this tablet, to post their build.prop and boot.img for each version they have, I am trying to see what the pattern is that is causing some versions to lose sound yet others don't.
Anyway all posts related to Nextbook Ares 8 5.1.1, should be posted in this thread, helps to keep all related posts in one thread, right now 3 or 4 threads have people posting about Nextbook Ares 8 5.1.1, most of those threads have nothing to due with this tablet.
A lot of people are contacting me, after failed attempt of using @greatbal instructions or backup, I have nothing to due with @greatbal, I did read his thread yesterday downloaded the backup he provided, unpacked it, and see that is for an entirely different device, His backup manufacturer Logitech.
It should be, manufacturer Yifang.
Yifang version is nxm890bap
Logitech version is ebm890bap
They indeed two different tablets, one might be able to port one version to the other, but just trying to use one version over the other would cause problems.
Anyway @greatbal did let people know what version he had, and I believe if you had the same version @greatbal had, you would have been fine, the differences in the hardware/software isn't @greatbal fault.
Update 3-22-2017
I have received the tablet from @Conan1201.
Below is a part of the build.prop, an important part is the last line ro.build.flavor, that was the fix for sound on my tablet.
Ok, some back ground, I got the tablet today, I work out of town stay in a hotel, my wife brought me the tablet and a small Linux laptop.
Setup tablet, enable usb debugging, reboot to bootloader
adb reboot bootloader
Now unlock bootloader
fastboot oem unlock
the tablet is supposed to reboot into recovery and format itself, it didn't I gave it 3 or 4 minutes.
I manually reboot tablet.
Got boot screen up android down recovery
choosing down, I get boot image error, which means recovery partition is locked, due to oem unlock.
boot into bootloader
fastboot oem lock
now reboot recovery no problem.
so recovery partition is out.
This tablet can have a permanent TWRP recovery, only temp TWRP recovery for now, I pulled system, recovery.img, boot.img, fastboot.img,ESP.img.
I backed doored the device and in doing so lost sound, I was able to recovery sound by examining different boot.img and build.prop there is always a pattern just finding it sometimes is the *****.
The pattern ro.build.flavor
Update 3-23-2017
Ok, I put together a Linux / Windows package to let people backup their tablet, you should do this before you root device or anything else some people lost sound, restoring your backup made by this recovery will fix that.
Download tethered recovery package
You need to extract to use, set permission on files if needed.

Now that the bootloader has been replaced flashing permanent recovery is possible, I already have permanent recovery on mine.
You all need a few more steps, the first is above backing your tablet up.
Next you need to get familiar with Carliv Image Kitchen for Android - unpack/repack boot-recovery

Those backed up boot.img need to be modified, we will get into that later.

Ok, I put together a Linux / Windows package to let people backup their tablet, you should do this before you root device or anything else some people lost sound, restoring your backup made by this recovery will fix that.
Code:
This is for LInux
You need to already have your tablet setup with usb debugging enabled.
adb reboot bootloader
sudo ./fastboot oem unlock
sudo ./fastboot format userdata (note this is optional, you will lose everything on internal sdcard.)
sudo ./fastboot format cache
sudo ./fastboot.sh
on tablet volume down until you see RESTART BOOTLOADER
power
sudo ./trigger 4
wait for recovery to load will take several minutes.
do a backup to micro sdcard, don't backup data or cache as nothing is there, back up system recovery boot to micro sdcard
Code:
I am don't use windows much from memory the below should be correct, look over it if something needs to be changed let me know.
Note [user=4821597]@social-design-concepts[/user] has a complete windows version of tethering twrp, you still need my files to switch bootloader, once that is done you can then use [user=4821597]@social-design-concepts[/user] tool, or continue using below instructions.
This is for Windows
You need to already have your tablet setup with usb debugging enabled.
adb reboot bootloader
fastboot oem unlock
fastboot format userdata (note this is optional, you will lose everything on internal sdcard.)
fastboot format cache
fastboot flash ESP esp.img
fastboot flash fastboot droidboot.img
on tablet volume down until you see RESTART BOOTLOADER
power
Note if you are going to use [user=4821597]@social-design-concepts[/user] windows tool use it now, else continue with my instructions.
fastboot flash /tmp/recovery.zip recovery.zip
fastboot flash /tmp/recovery.launcher recovery.launcher
fastboot oem start_partitioning
fastboot flash /system/bin/logcat recovery.trigger.new
fastboot oem stop_partitioning
wait for recovery to load will take several minutes.
do a backup to micro sdcard, don't backup data or cache as nothing is there, back up system recovery boot to micro sdcard
Note [user=4821597]@social-design-concepts[/user] tool listed below, any question on his tool ask in below thread, I have no personal experience, but I know it has helped many windows users.
