You are right, the facebook thing is odd. In the TWRP image you posted it is there, right were it should be. But in the pad after I installed the image that file is missing. I did not enable MD5 which may mean it was just a fluke, a bad read or transfer and it got ignored. Well, if anyone else has the problem you can always just disable it and use the market to install the latest version anyways. As far as the sound, the original firmware sound through the speaker was poor anyways, This ROM is not much worse. I see nothing to fix there, really. I have a hunch a variable is set different between the two, likely nothing more than that. But if you want I will poke around in the files between the two ROMs and see if I can spot the difference causing it.

Well since we're pretty much able to run i708Q roms on this tablet (with a few edits), is there cyanogen for the i708Q that we might be able to use for this tablet?
[Miscellaneous Android Development] Longstreet:
I've tried flashing vampirefo's TWRP backup and failed each time.

Rooted the tablet using the steps in the OP. Haven't changed anything until this morning. I dl'd the backup and tried to flash using the normal steps (TWRP backup, factory wipe, install zip) and get nada. I was using an earlier version of TWRP so updated to vampirefo's 3.0 and still get "Failed". The message reads

"Could not find 'META-INF/com/google/android/update-binary in the zip file.

Error installing zip file '/sdcard/Download/ares8_5.1_twrp_backup.zip"

I know I must be missing something simple here but can't figure out what it must be. Any ideas or directions?

Shoot, this is the post I meant to reference.

If I understand this correctly, I should be able to flash the backup zip just as if flashing a rom, yes?
[Miscellaneous Android Development] Rls4ever12:
You have to extract it then put it in your twrp backups folder
[Miscellaneous Android Development] Longstreet:
Aaaand that did it. I knew it was something simple. Thank you!

Still had a little confusion before I was successful. I unzipped the backup, copied to TWRP backup folder, rebooted. It didn't appear in the backup folder at all. If I went to Advanced>File Manager I could see it, but of course couldn't do anything with it. I then realized that I didn't see my previous stock backup either. Which was made with TWRP 2.8.7.0.

So rebooted into recovery to start fresh, made a backup with 3.0 which created a folder that 3.0 could read. Moved vampirefo's unzipped backup and voila!

Really like this rom. A few little quirks but nothing major, and it seems a lot snappier than previously.
[Miscellaneous Android Development] freddy999:
Wait until you bench the performance and compare to the stock ROM. It turns a $79.00 toy into a real powerhouse. I have run it since the hour it was posted and have had no real problems not already known with the ROM at all. And it looks like all of those minor cleanups are under control and will be fixed up shortly. If Nextbook had any sense they would reverse engineer it, duplicate it and offer upgrades!

Not that anybody might care but I tried installing Remix 2.0 rom by MOJO. It requires TWRP 2.8.2.0, can't use newer version apparently. I flashed old TRWP over the newer one and it all went to crap from there. She's a nolonger a bootin'. Power on goes directly to recovery. Except recovery is useless because adb will nolonger see the device and no option to flash.

I get the EFILinux kernel error and it says e: no media found

Any suggestions?
[Miscellaneous Android Development] vampirefo:
Never heard of Remix, you would need to report your problems where ever you got the ROM from not here.
[Miscellaneous Android Development] social-design-concepts:
I'm not even sure how you could post anything on any Android forum over the past two months and never heard of remixOS, either way the port of the ROM they're referring to isn't even for an Intel SoC, I'm waiting until the latest version comes out on the March 1st before finishing up my port / installer of it for Intel Android Tablets.
[Miscellaneous Android Development] vampirefo:
It's rather simple, I pay no attention to something that doesn't concern me, what device do I have that Remix works on?

Why do I need Remix? Why would I even both searching for it? So until this user posted it I never heard of it.

And according to your post it's not for Intel, so it's completely useless to me.
[Miscellaneous Android Development] social-design-concepts:
what device do I have that Remix works on : your pc

Why do I need Remix : True Multi Window / Tablet UI.

Why would I even both searching for it : you don't have to it's on every android sites front page.

according to your post it's not for Intel : the port that user is referring to but it is available for x86

Oh and sorry wasn't trying to be rude i meant it as it's been covered so much i didn't see how you couldn't of heard of it.
[Miscellaneous Android Development] vampirefo:
Well you can help him and anyone else interested in Remix, I have no interest in Remix.

[Miscellaneous Android Development] vampirefo:
Ever notice how much space Intel devices wastes?

I resized my partitions, I was surprised at the amount of waste.

I reduced cache by 800 MB, system by 500 MB added all to data, now data is 12.1 GB.
[Miscellaneous Android Development] Startrek852:
That's pretty amazing. How did you partition them?
[Miscellaneous Android Development] Startrek852:
[MENTION=7011825]Rls4ever12[/MENTION] I've got a test version of the sound fix ready for you to test. It's attached, just flash in TWRP. MAKE SURE TO MAKE A NANDROID BACKUP FIRST!!!

[Miscellaneous Android Development] vampirefo:
What? My ROM?
[Miscellaneous Android Development] vampirefo:
You have to wipe entire device, then change partition sizes to the size you want each partition.

There is probably another 300 to 400 MB, I could move forward to data. I just don't understand why Intel devices waste so much space.

No other device I have owned gives cache and system almost 2 GB more space than they could ever use.

The partition that is always installing stuff is data, the system and cache never really grow much.
[Miscellaneous Android Development] Startrek852:

Not sure what error I got should have jotted it down I know but my laptop is down so I have to be careful now with no way to Un brick it.
[Miscellaneous Android Development] zerozed99:
I've never understood why re-partitioning on Android was such a pain in the ass. Linux has had great partitioning tools for ages; you'd think that somebody could do something like QtParted for Android. I haven't bothered with partitioning Android for ages--the last time I did it was on my Asus TF-101 (which, BTW, is 5 years old and running Marshmallow). My recollection is that re-partitioning on Android is not for the feint of heart.
[Miscellaneous Android Development] freddy999:
I bricked one tablet (a wintec filemate x4) doing exactly that and to this day it remains a brick. But it was obsolete anyways so no real loss. Do not trust the marketplace programs that claim to have it all worked out. :)
[Miscellaneous Android Development] Startrek852:
There is a parted binary for android.
[Miscellaneous Android Development] vampirefo:
Partitioning the tablet from my Linux takes a minute or less, I would think same time or close to it via windows.

It's done via scripts in fastboot, the main file used is called partition.tbl, in this file you set your partition location, name and size, I only change size name and location remains the same.

How I partition my tablet, first set my tablet up how I want it check system size, use twrp to backup data, system, boot.

reboot into bootloader, edit partition.tbl to what I want it to be, then use my partition script, it uses fastboot commands and tablet's built in partitioning tool to do all the work, a minute or less real time.

now once script is done you are still at bootloader, select boot to recovery, in recovery restore your backup, reboot that's it.

I will upload files for those that want to try it, I will include my modified partition.tbl plus stock one, if you don't like my size you can return to stock, if you decide to use stock ares 8 rom, you will need to partition again using stock partition.tbl.

You all are welcome to choose your own size, you may want your partitions different size then mine or stocks.

[Miscellaneous Android Development] zerozed99:
I re-partitoned, and like an idiot I forgot to do my nandroid on an ext-SD...so the re-partioning wiped my nandroid. My stupidity aside, the .bat file worked great on Windows 10. One thing I've noticed--and this seems very odd--my battery life seems to have improved somewhat significantly since the re-partition. I know that doesn't make any sense, but before I partitioned the tablet would drain badly overnight. Now it's holding a charge fairly well. I can think of no reason why the partition size would affect the battery.
[Miscellaneous Android Development] freddy999:
I've noticed the last ROM, for some reason does the deep sleep thing correctly using the stock lock screen (it could be the difference was the previous version could not use the stock screen.....) and the power use when not in use is very minimal. And I see the same without any repartitioning. It is the ROM itself, not the partition.
[Miscellaneous Android Development] zerozed99:
I never use a lock-screen, but what you're saying about the deep-sleep makes sense. The stock Nextbook rom definitely had trouble "waking up." That was one of the things that always confused me about the tablet--when I'd look at the demo models at Wal-Mart, they would always appear real snappy. Of course they were plugged in 24-7 so maybe that helped? Regardless, the iView rom has completely fixed whatever it was .
[Miscellaneous Android Development] freddy999:
The stock ROM has a major problem in that when it "wakes" it is locked in to the lowest processor speed. I had installed a CPU governor to overcome that. (no frills CPU control from the playstore) Of course you had to be rooted for that to work and I find it is not a bad idea on the new Rom either. On occasion, I found the i708q ROM to do the same thing but that might be due to apps trying to take control and not the ROM itself. But if you use a third party control and set it for ondemand and noop and all of those wakeup issues are forever solved.

Can someone give me a step by step of what i'm supposed to do to root my nextbook 8?

I'm in windows 7, i started abd and put remove_encryption.zip, SuperSU246.zip on my msd card.

then i did adb reboot bootloader and held volume down which put me into fastboot mode.

What do i do next?

I tried going into recovery mode and doing the option "Apply update from external storage" and hit remove_encryption.zip but i get:

-- Install /storage/sdcard1/remove_encryption.zip ...

Finding update package...

Opening update package...

Verifying update package...

E:footer is wrong

E:signature verification failed

installation aborted
[Miscellaneous Android Development] Startrek852:
fastboot flash recovery twrp_recovery.img then boot to recovery and flash remove_encryption.zip and SuperSU246.zip. Make sure you backup your data first, because the remove_encryption.zip formats /data.
[Miscellaneous Android Development] shogunreaper:
i tried doing that

G:\android-sdk-windows\platform-tools> fastboot flash recovery twrp_recovery.img

error: cannot load 'twrp_recovery.img'

also how do i backup? I can only access my files via MTP so i can't see all the folders on the device.
[Miscellaneous Android Development] Startrek852:
Put TWRP in the platform-tools folder, then execute the command. Flash the SuperSU246.zip first, use Titanium Backup to backup all your apps to your Micro SD card, copy your /sdcard contents to your Micro SD Card, then flash remove_encryption.zip. But before you restore everything, I would recommend flashing the 5.1 ROM that vampirefo ported. Here's a link: http://xdaforums.com/android/development/ares8-5-1-rom-i708q-t3320040/
[Miscellaneous Android Development] shogunreaper:
nvm okay.
[Miscellaneous Android Development] Startrek852:
Do TWRP first. Sorry for being confusing.
[Miscellaneous Android Development] shogunreaper:
okay i'm in twrp

by flash you mean hit the "install" button and then go to the supersu zip right?
[Miscellaneous Android Development] Startrek852:
Yes. I can't help with anything else for an hour because I'm busy.
[Miscellaneous Android Development] shogunreaper:
oh okay sorry for bothering you.

but you said i need to backup the data folder... but i looked at it in the filemanager in twrp and its empty (or are the files hidden?)

also doesn't supersu require root? Am i already rooted?
[Miscellaneous Android Development] Startrek852:
OK, I'm back. No, I didn't say backup the /data folder, I said to use Titanium Backup to backup all your apps to your Micro SD card, then copy your /sdcard contents to your Micro SD Card. And if you flashed the SuperSU ZIP, then you are already rooted.
[Miscellaneous Android Development] shogunreaper:
okay, so what does removing encryption do?
[Miscellaneous Android Development] Startrek852:
Removing encryption speeds up the tablet by a lot, and then if you flash the ROM I posted a link to, It speeds the tablet up even more. It turns the tablet into a powerhouse.
[Miscellaneous Android Development] shogunreaper:
alright thanks for your help. I'm fine with it just being rooted right now, i might do that later though.
[Miscellaneous Android Development] Startrek852:
OK then, you're welcome.
[Miscellaneous Android Development] zerozed99:
Your tablet is still going to run for crap if you stay on the Nextbook 5.0 ROM. If you really want to get the tablet up to snuff, I highly recommend you re-partition it and then flash Vampirefo's Batville rom, which is based on the Iview Suprapad. This rom is based on Android 5.1.1. and doesn't have the memory leak that the Nextbook's Android 5.0 rom does. It is VERY fast. The only drawback to the rom is that the speaker volume is a bit lower. If you don't use rely on the built-in speaker this is the absolute best way to go.

[Miscellaneous Android Development] Startrek852:
I disagree. My friend ran the stock Nextbook 5.0 ROM for over a month and never experienced any lag whatsoever.
[Miscellaneous Android Development] shogunreaper:
well honestly right now i'm only using it to read manga, and i'm coming off a kindle fire (first gen)

whats this memory leak? I've seen people talk about it but i haven't noticed anything wrong, ram usually hovers around 500mb in use.
[Miscellaneous Android Development] freddy999:
What happens is the memory does not get properly released and eventually you have to re-boot the tab to get anything to run. You get crashes and such and things work poorly. The i708q Rom fixes all of that. As far as it being worth it, it is the difference of night and day. The tab as it was built was snappy, which is why I bought it. But it is markedly better with the i708q ROM. Even the bench tests come way, way up and there is no lag at all. What you are doing is taking a $78.00 tablet and refining it ti be much more like a $300-$400 tablet. The video writes and thus, the animations are smoother. Files open more quickly, and overall the performance is much better. It IS worth the time and effort. In addition by rooting it and removing the encryption you get the benefit of TWRP recovery which allows you to fix anything that might get borked up from your own backup. I have a tab at home dead because I have no way to restore it. And it can happen innocently, as that one did. A poorly written app made to increase available memory played with the root allocation table. Not a good plan and a $200.00 device that is not even a good paperweight. As you can tell I am very pleased with the results of this effort and I think you will be too, if you give it a test drive.

This minute I am running it on the original partition scheme and I am equally as pleased. I will likely re partition it when I find a bit of time just to gain the storage space but for a test drive of even just normal operation the original partition scheme runs just fine. It is just a bit wasteful! The only change I made was to delete bootanimation.zip because I did not like the non-animated boot. The default ANDROID comes up with a bit of fade to know it is running.
[Miscellaneous Android Development] Masterchief2017:
when I did the benchmark with the tablet stock I got a single core score around 300 and the multi core around 700 once I rooted, removed encryption, and flashed the iview ROM my single core went to 700 and multi core went to 2000.

On a side note I got my tablet off eBay for $50
[Miscellaneous Android Development] freddy999:
Actutu is about 4 times and quadrant (such as it is), about 8 times. I am quite impressed.
[Miscellaneous Android Development] zerozed99:
The memory leak is sort of like freddy described. It is present in all Android 5.0 devices, but was fixed with subsequent Android updates. Nextbook has never released a single update for our tab so we're stuck with the memory leak unless we root and use this rom. Everything about the new rom is faster. The benchmarks (e.g. Antutu) are astronomically higher. I wouldn't say it turns a $78 tablet into a $300 one, but it certainly makes it a fast, responsive tablet. The difference in speed is night & day.

If you're happy with the way the tablet is running then I wouldn't worry about it. If you do decide to re-partition and load the new rom, just plan on wiping and re-installing everything. The batville rom is free of bloatware, and by repartitioning you free up even more space on your tablet that you can use as well. The only thing you lose is the speaker volume and given time, somebody will probably figure that out (there is no problem with listening with headphones or via bluetooth).

"This is the most updated rom, includes camera and rotation fix.

To install place on sdcard boot into twrp and install like a normal rom or zip file, doesn't contain root, you can flash chainfire su to get root.

Twrp may seem like it's not doing anything but it is installing rom, once rom is installed you will see a button saying reboot to system, first boot takes a while.

I always start fresh and factory reset, it may or may not be needed you can try either way.

I can't find a solution to the sound being low, so it will remain that way unless someone else finds a solution and fixes it."

After several failed tries and almost "bricked" once, my rooting my nxa8qc116 tablet was successful! I chose not to do encryption as that is where I almost bricked my tablet.

Thank you for all your hard work! Your efforts and the efforts of all those at XDA have been instrumental to us that are at the very beginning to appreciate what can be done with Androids. Started with just learning how to allow permission to download other apks onto my old Kindle, to one-click-root my old Nextbook 7, and now actually used adb/fastoot to root my Nextbook 8! Fantastic! Thanks!
