[MENTION=1795879]Vortell[/MENTION] Sorry, I rarely ever checked this thread. The TWRP I have linked on Android File Host is the same and as far as I know, will work with all versions of the tablet with the Intel Processor. Stick with a version 1.XX of the rom, since yours is version 1.01.

An ARM version of the tablet was also released, which I do not own and my TWRP, of course, will not work with it. If yours is not Intel, then it is not compatible with any of my files.

I have been using the latest Canary and unofficial builds testing Magisk since version 15. 1 out of my five devices have failed. I run the latest Canary on 2 of them and an even more cutting edge, unofficial build on two of them. Magisk works great on these devices, I would never go back SuperSu.

Because I am using cutting edge builds, bugs do pop up from time to time. I do report them if they are in the Canary builds, to topjohnwu, but I never report bugs in unofficial builds as he does not want this.

I still have my 4 Nextbook Ares 8A's and update them frequently, but I have really moved on to the Onn 8 as it is so much better in almost every way.
[Miscellaneous Android Development] Vortell:
Yeah I saw you over in the onn forum, the thing it lacks it's HDMI out. I know about chrome cast and miracast/wifi display but they don't work very well. My 8a is lagging write bad but I assume it's due to the demo nature and super early os version. I have backed up can upload the twrp save off version 1.0.1 if you want it. It's a shame it's only 32 bit build though. This thing would probably be faster then onn if they had made it 64 bit and maybe give it 2gb of ram. Ran isn't as important as bus speeds and fully using each cycle of the CPU. It would probably run better in Windows. If I can get this thing not to be so laggy I want to try to install native x86 libraries so real Linux programs can run. I have a couple links some where for it. At least to try it.

I can't get any of the other kennels working on it. It's a shame since it tends to overheat and become useless. Might try to cut processor to 1.33 GHz like it should be and cut off the processors burst mode.
[Miscellaneous Android Development] Jutness:
I have a v 1.0.8

Id love to give the data you need and be able to jailbreak this device considering it is a very slow tablet and sucks up all its battery fairly quickly as well and wanted to jailbreak for fixes
[Miscellaneous Android Development] Vortell:
It's ready to get root it's just my tablet has demo software on it and it works more like an alpha build rather then production ready build. If I restrict CPU to 1.4 GHz using kernel manger it helps. Since my worst issues were over heating based.
[Miscellaneous Android Development] Jutness:
V1.0.8

I also noticed the rear cam when stationary for a long time likes to auto focus back and forth on nothing as if i had zoomed in or out probably just a software glitch with the camra app and i also have noticed the power flux as well like its trying to conserve battery

Anyways as for your comment about the overheat maybe i can try to do so but in the mean time if you can pm me we can work out a where i can send you the file
[Miscellaneous Android Development] slipk487:
Can't seem to get magisk modules to install. Magisk manager from twrp shows there installed but nothing shows up in magisk after booted to android.
[Miscellaneous Android Development] martyfender:
[MENTION=3930886]slipk487[/MENTION]

Newer versions of Magisk broke this. You have to use an older version of Magisk. I can't recall if it is 20.1 or 20.2, since I have been using Canary builds. It was commits after Dec 8th that caused this.

https://github.com/topjohnwu/Magisk/issues/2182
[Miscellaneous Android Development] Vortell:
I haven't been able to get the newer os versions on my 8a. You every run into an issue like that?
[Miscellaneous Android Development] trev1lov3:
Hi. Have one of these but build version 2.1.1 I've been reading but admittedly hadnt read through all 78 pages yet but I didn't see in your updated op that you had one that might work with this build? I'd love to make better use of this thing and root it if possible *** sorry just got to page twenty
[Miscellaneous Android Development] martyfender:
What do you mean by newer os versions? All Intel versions of this tablet have Android 6.0.1. There are no newer versions that I am aware of.
[Miscellaneous Android Development] martyfender:
I updated the OP to help get you prepared for the future release of the necessary files.

So get ready for an exciting adventure, if this is your first attempt at rooting an android device. If not, please be patient, because this tutorial is for the newcomer to the domain of android rooting.
[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] So how do I go into recovery mode?
[Miscellaneous Android Development] martyfender:
See post #5 on how to boot into stock recovery. Warning, don't try to flash unsigned install zips through this, it will fail. I think usually you can only flash vendor update files through this. As far as I know, Nextbook has never released any.

You will need to wait for me to release the TWRP recovery to be able to flash zips such as supersu.zip, busybox.zip and others. And of course, I am still waiting to get a developer account on AFH before I can upload the files. If I don't get their confirmation email in a reasonable amount of time, I may temporarily post the files on my Google Drive.
[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] Ok, I can't wait for this great tablet to be rooted! :laugh: :laugh: :laugh:
[Miscellaneous Android Development] martyfender:
FILES ARE NOW UP ON ANDROID FILE HOST. SEE THE LINK IN THE OP, TO DOWNLOAD THEM.

Please post here for successes and if you have any problems.

I strongly advise you to read my instruction in the OP (opening post), to avoid any complications with drivers, adb and fastboot.

I assume no responsibility if you brick your device in the process of using these files. You are responsible for that.

I will, however, try to provide support when ever possible, just don't expect an instant response as I do have a job and life outside of XDA.
[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] Where is the link, I'm so excited for rooting!
[Miscellaneous Android Development] martyfender:
In the OP (opening post). Make sure you have read the instructions in the OP and are all setup before attempting this.

Please give me feedback on how it goes.

Thanks
[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] so what does the "older" and "newer" boot.img refer to. Old is v1.1.1 and newer is v1.2.0?
[Miscellaneous Android Development] martyfender:
That information is in the instructions in the OP, however:

Yes, the old is for the 1.1.1 version of the tablet that doesn't require activation on startup. The newer is for the 1.2.0 version of the tablet that requires an activation code from your purchase receipt the first time you boot the device.
[Miscellaneous Android Development] martyfender:
I updated the OP with a new download link. The files are now live on Android File Host.
[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] Thank you you're a lifesaver, along with anyone else who helped!
[Miscellaneous Android Development] martyfender:
Have you successful flashed the boot.img, twrp.img and supersu.zip with no problems?
[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] The intel drivers and system wide adb links aren't working
[Miscellaneous Android Development] martyfender:
I will check and update:

https://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices

https://xdaforums.com/showthread.php?t=2588979

I tested these both and they work, so I will have to check the OP to see what is going on.
[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] Thanks man, these links do work!
[Miscellaneous Android Development] martyfender:
It is fixed in the OP, now. Thanks for bringing it to my attention so fast. I copied and pasted when editing and somehow did it wrong.
[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] in adb, whenever I put in "fastboot boot Ares8A_recovery_twrp.img" it always says cannot load '...' No such file or directory. I don't know where the twrp file is and it also says "error: cannot determine image filename for 'Ares8A_Old_boot.img'
[Miscellaneous Android Development] martyfender:
Forgive me, I uploaded the wrong zip. I am re-uploading to to android file host as I type.

Here it is, corrected:

[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] I clicked the link and it said "no folders, no files".

Edit: Nevermind, I didn't look correctly.
[Miscellaneous Android Development] Vortell:
I'm on 1.0.1 firmware can't get any of the other ones to work. Maybe I messed up the data deletes.... It maybe since mine a demo model it just will not work. I'm not sure.
[Miscellaneous Android Development] shaun279:
Just out of curiosity, what's your IFWI version? Can be found in "About Tablet" in settings or booting into bootloader menu.

If the demo model has the same hardware as the official models, you could in theory flash official firmware to it. I haven't touched my intel Nextbook 8A in a while but what I recall so far is I'm able to dual boot into it and have complete access to all of the partitions.

Also If you want to check what audio chipset your Intel Nextbook 8A has without opening the back cover, boot into TWRP, mount system, then file manager.

Go into the directory "/system/etc/parameter-framework/Structure/Audio" and you'll see a .xml beginning with either "Everest" or "Realtek". In my case I have "Realtek5651Subsystem.xml" which tells me I have a Realtek audio chipset. You can do the same on system images that OP uploaded too to make sure it's compatible with your device.
[Miscellaneous Android Development] Vortell:
Ifwi version is M882_JJ.015. Dual boot it as in Linux? Or windows? I am not sure about bit system. I have read many Intel based tablets can be modified with correct Intel firmware software. I have root so umm i just looked audio subsystem up with mixplorer. It's Realtek5651.
[Miscellaneous Android Development] shaun279:
I managed to boot into Ubuntu from micro sd card but had a whole bunch of issues so I only used it as a utility to repartition the storage to get me some extra gigs and unbrick the device from screwing around.
[Miscellaneous Android Development] Vortell:
Do you remember what versions worked best in yours? On Current os it is kind of a turd. Especially considering the processor. It hangs and gets the warning message is taking a long time works you like to end the process message.
[Miscellaneous Android Development] shaun279:
Ubuntu on this device is pretty much broken. Touchsceeen doesn't work and is super slow. I wasn't able to run any other distro. If you still would like to boot into Ubuntu anyway and play around with the system, lookup "Linuxium isorespin.sh intel atom". I never tried windows, probably even worse I would imagine.

You can try debloating your system with Link2SD. It's a powerful app and can easily brick your device so make a backup first and research what the app does before you disable it and you should be good. Went from about 30 apps to 10 apps and noticed some improvement. Note that you only have 1 gig of RAM so you'll have to keep yourself from having too many processes running. In developer settings all the way down, you can configure apps to never run in background.
[Miscellaneous Android Development] Vortell:
I know all about removing apps and limiting background apps. I even limited the processor to 1.44ghz so it wouldn't overheat and turn the screen brightness down. I mean it seems like your saying even then you have issues. It's a shame I have a Asus a1-850 running an Intel processor with 1gb of ram and it doesn't show down like this. It's even one generation earlier processor. It isn't running a 64 bit os though, never checked this one. I guess Nextbook os was build shotty. I have also had a Windows in tablet that only had 1gb it's team on the same older processor. It ran fine but had several limited application selection that would run on it. I assume this had got efi then since you got Linux to run. That's neat but pointless if it runs poorly. Guess I should have guessed Android 5.1+ -6.0 had issues even on arm. My s5 note 3 and note all had issues with it. Here I was hoping for a cheap decent tv box.
[Miscellaneous Android Development] shaun279:
Hmm I might actually try to run windows 10 and see how it goes

Update: With otg cable + keyboard, I booted into UEFI by pressing Escape, then Boot Selection, selected the micro sd card and booted straight to blue screen with error saying not enough memory. I don't have the 32 bit version .iso of windows 10 and my internet is super slow right now. Looks promising though

In UEFI there are some settings related to thermal stuff so maybe that could help but be highly cautious of changing anything. I had another nextbook, the only difference is it has a Everest audio chipset, changed one setting in UEFI and boom, complete brick now.
[Miscellaneous Android Development] Vortell:
Oh wow it's crazy it bricked that easy. It's hard believe it wouldn't boot back into uefi. I have read on intel tools for that. Many tablets don't have such easy to access uefi. I don't have 32 but Windows either but drivers are super important too. Of course it sounds like pretty well supported drivers considering it has realtek audio and Intel atom is has GPU built in. The display though might be an issue. I think all that would limit is touchscreen though.
[Miscellaneous Android Development] shaun279:
Been playing around with the UEFI settings while being cautious, so far no brick. I disabled HPET which was enabled by default in UEFI and immediantly noticed a huge increase in responsiveness. Give it a try and see how it works for you ;)

WARNING: CHANGING ANY OTHER SETTING MIGHT PERMENANTLY BRICK YOUR DEVICE, there is currently no way to reset the UEFI.

You'll need a keyboard and a OTG cable. Turn off your nextbook then hold the power button and spam the Escape button, doing both at the same time until you see the selection menu. Use the arrow keys to navigate and enter SCU. Go to Advanced tab, Chipset Configuration, then Miscellaneous Configuration. Set "HPET - HPET Support" to disabled then finally press F10 on your keyboard to save and exit.

[Miscellaneous Android Development] raz0r9111:
I work at a phone repair store, the customer left with the tablet, i got myself a broken backup of her tablet, supposedly it shows system error after a week or so but it boots up and everything, i might upload it myself in case it works on another tablet for someone else, if yours works perfectly it would be nice for anyone who might look for it in the future, if you are busy i'll do it myself, godspeed and thanks.

Here is a great busybox installer by YDS, just updated today to the latest version of busybox v1.27.1

https://xdaforums.com/android/software-hacking/tool-busybox-flashable-archs-t3348543

From the download link choose the x86 version and flash it from twrp.

To get it to flash properly, in the past in twrp hit the mount button in twrp an check system, then go back to the main menu in twrp and hit install and choose the busybox zip file to flash it.

He also has a link for a busybox cleaner the get rid of older versions. I prefer this over Stephen Stericson version. There is no bloat and advertising in it and he updates it on a regular basis to to newest, stable, busybox available.
[Miscellaneous Android Development] martyfender:
If you decide to flash twrp permanently, go into it's settings and choose your time zone and preferred language. From what I have seen these setting changes do not stick when booting from temp twrp, which makes sense.

I have tested both backup and restores and it works great.

I now have the version 1.2.0 version on my older, 1.1.1 tablet. There is no apparent difference in it, Just a different build ID. It Has the same kernel version, android version and the same apps, I believe.

My guess is that activation on the newer tablet is hardware based because I can see no signs of it on my older tablet. On the newer tablet there is a setting called disa reset which does not show up when the newer 1.2.0 rom is flashed to the older tablet.

The activation technology is from this company:

http://disa.sg/

I purchased the newer tablet where I work, Walmart and I will be returning it tomorrow.

We don't have many left which leads me to believe there possibly could be a newer version on the way or Walmart is discontinuing it. I'm not sure at this point. I don't work in electronics.

Anyone flashing this in linux (Linux Mint Mate), should know that not all fastboot binaries contain the flashing unlock command built in, as I found out. In the software manager, if you search for fastboot, there are three listed. The first one: Android-Tools-fastboot, which by the way, has a high rating, does not have the commands for unlocking built in.

The second: fastboot, does have the necessary commands, built in .

I also installed the third: golang-goget-ubuntu-touch-devices-dev, I'm not sure if it was needed, or not.

I have been testing Linux Mint Mate 18.1 running on a 28gb usb thumb drive. I is created as a persistent drive which allows reading and writing to it, like a normal hard drive install of Linux.

Despite being on a slower thumb drive it boots and runs much much faster than my Windows 7 home installed on my hard drive. I may eventually Install it to my hard drive. If anybody wants information on how to do this, let me know.
[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] I was able to flash the files, I now have an unlocked bootloader, modified boot image, SuperSU, and root installed. I did have an issue with twrp, I wasn't able to mount /data, so I couldn't backup all of my partitions, only half. If you could have me get twrp to mount /data then I would say this was a success.
[Miscellaneous Android Development] martyfender:
any previous data was encrypted so I don't think you will be able to mount it.

That is why I stated you need to backup any important data first, like through mtp connected to your computer. Or an app like titanium or helium. I'm not sure as I've never used any of them. For this to boot properly unencrypted you need to run the format userdata and cache to delete it and boot to a fresh setup screen, unencrypted. All userdata will be deleted. Time to leave for work.
[Miscellaneous Android Development] therune:
For some reason I ended up with non-functional WiFi after going through this process. Tried clearing cache again and running a factory reset but when I go into the WiFi menu it sits on "Turning Wi-Fi on..." and never finishes. Everything else seems to work, recovery and root both work.
[Miscellaneous Android Development] martyfender:
You have me stumped. I have both the are 8 and 8a and I have never experienced that before. This is a long shot, but boot into twrp, choose wipe, advanced wipe, select dalvik cache and cache and wipe them then reboot.

What is your build number, reported in settings, build number at the very bottom?

There are only 2 that I am aware of.

Please report back the result. Let me know what version you have and I may be able to upload a twrp backup to android file host. I am almost out of room on my ext sd card, but can back up to the computer to create space for a version with userdata deleted so I don't give out personal info.

let me know.

Did you do twrp backups you can go to?
[Miscellaneous Android Development] TurnaboutSavage:
I have successfully gotten root access and installed busybox, as seen in these screenshots.
