[MENTION=2472806]vampirefo[/MENTION] this might be of limited interest to you...the previous post is the second I've seen with folks saying they're tablet has come with 5.1. I have yet to see any of these in the wild.

I contacted Nextbook months ago when they changed the device's webpage to list Android 5.1, but they claimed there was no update, but that they'd be releasing new models later in the year. I'm wondering if these new Nextbooks might actually have different hardware since both of the guys who say their tabs came with 5.1 have struggled to decrypt, etc.
[Miscellaneous Android Development] vampirefo:
I can't say for sure, haven't seen them, my guess the partitions and bootloaders are different.

I wouldn't recommend using the boot.img from 5.0 on 5.1.

The hardware might also be different, the partitions, boot.img and bootloader would most likely be different.
[Miscellaneous Android Development] codyw1996:
I'm pretty sure the stock recovery has been updated. On my tablet it mentioned that the version release was dated sometime in may of 2016. I don't remember exactly what it was, because now i'm locked out of the recovery.

Also, I googled that "the command is not allowed in this device state" error, and from the posts i've read, that seems to indicate that the bootloader is locked, but apparently the tablet that came with android 5.0 did not have a locked bootloader. Well, all I know for sure is that my tablet is bricked now.
[Miscellaneous Android Development] vampirefo:
I can't help you, My rooted method was made for 5.0, if I had 5.1 I could probably find a method to root it as well, but I don't have one.
[Miscellaneous Android Development] codyw1996:
If you live in the U.S. I could just ship this one to you. You can only access the bootloader though, so I don't know how useful it would be to you.
[Miscellaneous Android Development] vampirefo:
It still should be under warranty, you can send it to nextbook for a replacement.

If you had it less than 14 days return it to Walmart for a replacement.
[Miscellaneous Android Development] codyw1996:
I didn't think to keep the box, or the receipt.

I'll probably just buy a replacement motherboard on Ebay. Luckily these things are really easy to service.

The back comes right off, and the battery isn't soldered to the board.

Hopefully I can get one with Lollipop 5.0 installed.
[Miscellaneous Android Development] vampirefo:
Yeah, you can buy the 5.0 tablet on eBay rather cheap.
[Miscellaneous Android Development] vampirefo:
I am interested in the tablet you have, I may be able to fix it if you send it to me.
[Miscellaneous Android Development] codyw1996:
Tablet possibly unbricked.

Ok, I have some good news. I figured out why the ./trigger 4 command wasn't working. I had to first unlock the bootloader by running

./fastboot oem unlock

Duh, I feel stupid. Anyway, I am now in tethered TWRP, and I will update this post if I manage to unbrick my tablet.

UPDATE

Yeah, I can now boot back into android. It just warns me every time I boot that the system has been modified.
[Miscellaneous Android Development] vampirefo:
Make a backup of 5.1 and upload it, would be nice to have.

Only backup system and boot.img for sharing, data is your personal info don't share it.
[Miscellaneous Android Development] codyw1996:
Ok, I think I flashed your boot.img, so i'm not even sure if you want that.

I'll just share system.

---------- Post added 4th August 2016 at 12:16 AM ---------- Previous post was 3rd August 2016 at 11:55 PM ----------

Ok, so I made a backup of the stock android 5.1.1 system partition. I didn't do it in .img form, so I hope that doesn't matter.

I'll upload it to my Dropbox in zip form soon, and i'll update this post after it's ready.

I went ahead and flashed that I708Q rom which is working perfectly. Thanks for that Vamp.

Ok, here's the link to the backup, https://www.androidfilehost.com/?fid=24665509702140041
[Miscellaneous Android Development] vampirefo:
Thanks, did a quick test on it last night, The 5.1 hardware is different than the 5.0 version.
[Miscellaneous Android Development] codyw1996:
How exactly do they differ?
[Miscellaneous Android Development] social-design-concepts:
Back up of esp and droidboit.img be nice too
[Miscellaneous Android Development] vampirefo:
Sound, camera, partitions. The 5.1 rom can be ported to 5.0, same as I port Iview rom swapping out files, but it doesn't appear to be as good as iview rom.
[Miscellaneous Android Development] zerozed99:
I'm surprised Nextbook is even bothering to keep releasing the Ares 8 with Lollipop since Android 6 is the baseline standard at this point--would have made more sense for them to spec out a new device with Marshmallow instead of sourcing different components for the Ares 8 and having to invest resources into 5.1 for the altered version. I'm surprised there's much of a market for an Android 5.X device still--even if there is, it'll be diminishing sooner than later and they'll be left with unsold product.
[Miscellaneous Android Development] MODZ4FUN420:
I am doing this on windows. i put adb reboot bootloader then i put in fastboot boot boot.img and in the command prompt it stays at waiting for device. What am i doing wrong? What are the proper commands for each step i need then? Need some help. Been stuck at this point for hours now and this is my 2nd attempt this month. Thanks ahead of time for the help and i will hit the thanks button for al the help.
[Miscellaneous Android Development] Startrek852:
Did you install the proper drivers?
[Miscellaneous Android Development] MODZ4FUN420:
i'm guessing not. i must need fastboot driver or some thing.?. What drivers are needed? Can you link me please?
[Miscellaneous Android Development] Startrek852:
You need these drivers: https://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices
[Miscellaneous Android Development] MODZ4FUN420:
I am rooted. Thanks!!
[Miscellaneous Android Development] Startrek852:
You're welcome.
[Miscellaneous Android Development] jley22:
Ok. I've tried just about everything I can find for this. I am trying to run this method from debian. I have installed the android-tools-adb and android-tools-fastboot, I have setup permissions in udev for 99-android.rules and 51-android.rules, I am fully able to use adb commands, and adb devices shows my device ID. Fastboot however is a total no-go. No matter what I do, it will not recognize the device. fastboot devices returns nothing. I've done sudo, and logged in to root and tried it there. Same result, nothing. Any other commands it just sits and waits on the device. I can see it connected in "lsusb", but fastboot can't see it. Any insight?
[Miscellaneous Android Development] Startrek852:
Try using vampirefo's fastboot binary.
[Miscellaneous Android Development] jley22:
I forgot to mention, I am using his binary.
[Miscellaneous Android Development] Startrek852:
In that case, I have no idea.
[Miscellaneous Android Development] jley22:
I may just be dumb. I apparently wasn't using his binary, because now that I try it is saying it can't execute the binary file due to an Exec format error. I read a little on this and it looks like the reason is my OS I guess? So I'm setting up a virtual box on another linux distro and I'll do it from there.

EDIT:

Yep I'm dumb. I was using debian on ARM architecture. Ran a VM with linux mint 64 and 32 libs, fastboot is fully functional. Thanks for the nudge [MENTION=6622051]Startrek852[/MENTION] !

EDIT 2!:

So, I've attempted to root like 5 different times. FOllowed the guide to the T. I have twrp no problem, but supersu isn't installing. It installs fine within twrp, then I get back into android and no root. Even checked with a root checker.

FINAL EDIT!:

As it turns out, the recovery prompted by doing ./trigger 4 allowed proper installation of supersu. All is well in the land of Nextbook. Thanks!
[Miscellaneous Android Development] michaelc5047:
For what it's worth, I did not get mine fully rooted until I got the newest SuperSU 2.76 Stable. But it's working like a dream! Thanks.
[Miscellaneous Android Development] Tuzuriro:

[Miscellaneous Android Development] Startrek852:
Did you format /data and /cache?
[Miscellaneous Android Development] Tuzuriro:
Unfortunate no, i didn't format anything before doing the rooting process. :(

ps: any one have backup the stock boot.img please share it to me badly need.

hi guys any one who can help me? how can i reflash this to stock rom?
[Miscellaneous Android Development] Tuzuriro:

Stock image NXA8LTE116

Does anyone have a stock image or a dump for the Ares 8 that has Verizon LTE built in? The model is NXA8LTE116
[Miscellaneous Android Development] Tuzuriro:
hi sir, can you give me the unmodified boot image that you use in rooting process that you have provided in the first page. because my tab can boot with that boot image but i can't use my tab because every thing get freezes. thx
[Miscellaneous Android Development] tamcdonald:
Hi Guys. I used this method to root/decrypt my Ares 11. Everything seemed to go smoothly and I got booted back into Android. The only problem is now the touch screen is useless. It repsonds very erratically and registers several touches at once in places I'm not touching it. Has anyone seen or heard of this issue or know of a fix for it? Thanks
[Miscellaneous Android Development] vampirefo:
You can't use the ares 8 boot.img on ares 11 the tough screen is different.

You need to flash ares 11 boot.img.
[Miscellaneous Android Development] tamcdonald:
Do you know where I might find that?
[Miscellaneous Android Development] vampirefo:
The ares 11 thread.
[Miscellaneous Android Development] BobC4012:
Thanks for this

Thanks for all your posts and helpful information. I have a Nextbook 8, but not sure if I will try rooting it. It does act weird with the SD card, sometimes it knows it there, but other times it doesn't. Even when it knows its there, it will drop it. Apps that will save other apps to the SD card know one is there and go through the motions, but nothing gets saved. I should have returned it for another one, but didn't realize I had only 2 weeks for returns. Again, just wanted to thank you for what you have done.
[Miscellaneous Android Development] JCDinPGH:
missing remove_encryption.zip

I just won this tablet and am looking to root and install TWRP on it. Anyone have a link to the remove_encryption.zip file? The files in this thread did not include it.
[Miscellaneous Android Development] JCDinPGH:
Somehow I managed to corrupt the ROM. I can still get into the boot loader and also TWRP but it won't boot normally. I found that someone else had made a TWRP backup of a stock ROM but for whatever reason, when trying to restore it to my tablet, TWRP says it ran successfully (in 4 seconds which seems very unlikely), but it really changed nothing. I let it sit over night just in case I wasn't waiting long enough. No luck. I tried formatting from within TWRP also. What's odd is that even though TWRP seems to boot correctly, not all of the functions seem to work 100%. I tried 3 different versions of TWRP (2.8.70,3.0.0.0 and 3.0.2.0). The only thing that seems to work consistently are commands (adb,fastboot) when in the bootloader.

So my question is, is there a way to return to stock ROM from the boot loader?
[Miscellaneous Android Development] vampirefo:
My guess the problems you are running in to, is this method is for Ares 8, 5.0, you most likely had Ares 8, 5.1.

I don't have Ares 8, 5.1, and don't provide any support for it.
[Miscellaneous Android Development] Tuzuriro:
We have the same problem, but i was able to recover by Ares Tab running on android 5.1.1. i just used this TWRP backup rom https://onedrive.live.com/?authkey=...!931&parId=19085CD12562E567!925&action=locate that is android 5.0 but it running fine on my ares. i hope somebody upload the Ares 8 rom android 5.1.1

Question on Ares 8

Hey guys and gals,

I am about to purchase the EXACT tablet that was mentioned earlier in the thread. It is the exact tablet this thread is about

Ares 8 with 5.0

I have a simple question I plan on rooting this tablet ASAP. I have rooted numerous phones before but always had a PC at ny disposal.. Currently I HAVE NO COMPUTER..

CAN I ROOT MY NEXTBOOK ARES 8, INSTALL CUSTOM RECOVERY, AND CUSTOM ROM WITHOUT A COMPUTER??

And remove encryption of course...

With no computer??

Please let me know, thanks..

-GotR00t?
[Miscellaneous Android Development] zerozed99:
No. You need a computer to achieve root using the method [MENTION=2472806]vampirefo[/MENTION] created. You might try something like King Root but I doubt that would work.
[Miscellaneous Android Development] Startrek852:
No, you cannot root this tablet without a computer.
[Miscellaneous Android Development] greatbal:
So how is your experience with rooted, unencrypted 5.0 compared to stock 5.1? Any feedback with regards to memory leak if it's noticeable?

I have an Ares 5.1, and I would like to have it rooted. I don't mind downgrading to 5.0 as long as the memory leak is not that big of a problem. Any feedback would be appreciated. Thanks.
[Miscellaneous Android Development] vampirefo:
Don't downgrade to 5.0, that's not a good ideal stay with what you have.
[Miscellaneous Android Development] greatbal:
Thanks. Can i use the procedure on OP to just install twrp and root my device and keep my Android 5.1? If I don't format system, will this work?
[Miscellaneous Android Development] vampirefo:
This method is for 5.0 not 5.1 do as you like, it's your tablet.
[Miscellaneous Android Development] greatbal:
Yes I know. I've read the original post 10 times before joining the thread. but apparently some people with 5.1 did it but downgraded to 5.0 by using a 5.0 TWRP backup. If you noticed, I just quoted that someone, and asked him because I was interested to know about his experience. I also have a 5.1 but is interested in rooting, and doesn't really mind downgrading to 5.0 as long as I get root and TWRP.

Thank you for this thread and your efforts.
[Miscellaneous Android Development] Tuzuriro:
Can you please give me the boot.img of your rom i want to upgrade to 5.1. don't downgrade it really bad experience it hangging a lot not like 5.1 running smooth. just backup your boot.img via twrp and please upload it.
[Miscellaneous Android Development] vampirefo:
Regardless of their experience, downgrading 5.1 to 5.0 is a bad ideal, and one you will regret.

Anyway good luck to you, I have other projects to work on.
[Miscellaneous Android Development] vampirefo:
Hopefully he can help you. Perhaps you can help him and others with 5.1 not to mess up their tablet's by downgrading to 5.0.
[Miscellaneous Android Development] Startrek852:
It probably will work, as long as you run "fastboot oem unlock" before doing anything else, and you DON'T flash the boot.img or the remove_encryption.zip.
[Miscellaneous Android Development] Tuzuriro:
Yes that's right it will work, cuz i flash twrp and when i entered recovery it will not go through due to error cause by oem locked. before i figured out the fastboot oem unlock i already flash the boot.img of 5.0 cuz i think the causes of error is the boot.img but found out the real cause is oem is locked.
[Miscellaneous Android Development] greatbal:
Ok. Thank you for the info. I will think twice before doing it, and think another 2 more. And prepare a backup plan before diving in, just in case something goes wrong. Based on feedback, I guess unrooted 5.1 is a lot smoother than rooted and unencrypted 5.0, so i really have to weigh what is more important to me, i.e., being rooted or having a more solid performance. :P
[Miscellaneous Android Development] zerozed99:
If your tablet already has 5.1 then it is incredibly stupid to attempt a downgrade. All the info in this thread is for a different version of the tablet. People have bricked their tablets by doing what you're considering. When the dev tells you not to try it you're well advised to listen.
[Miscellaneous Android Development] greatbal:
Ok. Finally my Nextbook Ares 8 arrived. used it for more than 3 hours straight just to drain the battery. Bought it for PHP2,850 or roughly USD55. I used four other Android tablets in the past and I must say, this is the best tablet I've used for it's price. Mine is running Android 5.1. Most reviews I've read are running 5.0. Too bad. Nextbook released a new batch with 5.1 and it's running pretty well. They should have released a 5.1 rom update and posted it on their website for those who are still running 5.0. Tsk....

Antutu score is 49T+. Damn! Nice cheap tablet!

To drain the battery, I connected it to my HDTV via hdmi. Connected an airmouse via OTG. Played some youtube videos for more than an hour. Then Connected a BT Gamepad and played some games. Working pretty well. I must say that this tablet has found its place beside my TV for movies, videos and games. hehe :P

Yes camera is crap. Internal speakers crap. But sound via headset and thru hdmi is ok. And really nice screen for it's price.

Will post original 5.1 boot.img for those want it tomorrow. and Will root this tomorrow. :P And will post a TRWP 5.1 backup, and hope it can be of any use to the others.

Has anybody discovered a mod to increase the speaker sound? Anybody installed xposed framework?
[Miscellaneous Android Development] greatbal:
ok. Ready to make the plunge and try to root my Ares 8 with 5.1

Steps I will take:

1) I will be using Windows. Will install adb/fastboot intel drivers

2) enabled developer options / adb debugging under settings

3) adb reboot bootloader

4) fastboot oem unlock

5) fastboot flash recovery twrp_recovery.img

6) reboot to recovery

7) backup original boot.img in twrp

8) install supersu in twrp

9) Don't install modified boot.img on OP

10) Don't Wipe System!

11) Reboot

I hope all goes well...
[Miscellaneous Android Development] greatbal:
1) Success

2) Success

3) Success

4) Success

5) Success

6) Success

7) Success

8 ) Success

9) ok.

10) ok

11) Reboot - Bootloop! :(

Any help would be highly appreciated...
[Miscellaneous Android Development] vampirefo:
Start your own thread for Ares 8 5.1

Your posts has nothing to due with this thread which is rooting Ares 8 5.0.
[Miscellaneous Android Development] greatbal:
was able to fix it by modifying my stock boot.img and was able to boot normally. Thank you for this thread and your efforts. Thanks!

Sorry for flooding your thread. There's no other thread re 5.1, and there are people with 5.1 who are coming over here. So, I was thinking to post here so maybe I could help the others with what I was doing. Again sorry... This is my last post here...

My solution posted here (for those interested): Nextbook Ares 8 Stock 5.1.1 Rom modified boot.img; Rooted and Unencrypted TWRP Backup

I also posted a port of the Remix OS 2.0 for Nextbook Ares 8 NXA8QC116. If anyone is interested to try and play with.

Seems like the new android 5.1 update locks the bootloader. How can I unlock it?
[Miscellaneous Android Development] zerozed99:
What "new" 5.1 update?
[Miscellaneous Android Development] Startrek852:
There's a new version of this tablet that comes with 5.1 and a locked bootloader.

---------- Post added at 04:22 PM ---------- Previous post was at 04:04 PM ----------

Boot into the bootloader and run fastboot oem unlock.
[Miscellaneous Android Development] zixxorb:
Well I was using my tablet this morning fine. Turned screen off and left it alone for a couple hours. Went to use it again and its stuck in a boot loop. I have access to adb but cant even boot into twrp. If it helps, I was using vampire's custom rom. Any help would be appreciated.

---------- Post added at 03:12 AM ---------- Previous post was at 02:49 AM ----------

Nvm. Got it to boot when unplugged it from my computer. No idea what happened
[Miscellaneous Android Development] nannycrick:
Hi Vampirefo, it's nannycrick!

I just picked up this tablet, and I'm trying to root it using Windows 7 x86, running in test mode with driver signing disabled, and ADB installed. (I have other rooted devices).

Followed your instructions, and ADB just sits & waits for device....

What step did I miss?!?

Sent by my rooted HTC Desire 626s running Nightbreed MM rom.
[Miscellaneous Android Development] nannycrick:
Okay. Drivers from that link are for Samsung and I already have Kies3 installed.

Is there ANY working root for us Windows users?
[Miscellaneous Android Development] nannycrick:
Root efforts update....

Success..and this is how for Windows 7 users....

1. Download everything from OP, and download/install PDAnet for Windows. (have your tablet plugged in , pc hooked up to the network before install) When the installer asks what device maker it is, choose Other.

2. After install, reboot your pc.

3. Then put your tablet into bootloader mode, unhooked to the pc.

4. Move boot.ing, twrp.recovery.img into ADB folder that you placed into root of C:\ drive on your Windows pc.

5. Click Start/Run button in lower left corner to open search box.

6. Type in cmd. Windows CMD icon will appear. Right click it, and Run As Administrator.

6. Type in...cd C:\ (then the name of your adb folder), and hit enter.

7. Plug in tablet. Wait until driver installs.

8. Type in adb fastboot, and hit enter.

9. For boot.img flash...type in..

[fastboot flash boot boot.img.]

Boot image will run, then tablet will say okay.

10. For recovery flash..type in...

[fastboot flash recovery twrp.recovery.img.]

recovery will flash, then say okay.

11. Disconnect tablet and follow directions in OP to reboot into recovery.

12. Unzip the remove_encryption.zip download, and place contents on root of sd card.

13. Install latest version of SuperSU.zip. version 2.79 is newest stable version.

14. Make first backup and save to micro sdcard.

15. Reboot system, and install Busybox.

16. Reboot, and enjoy!

My thanks to vampirefo, and all the contributers, especially the guy who shared his results with PDAnet!

Sorry I don't remember his name. I did so much surfing on the net with this, I forgot which forums I've logged in to!

My HTC phone wasn't this much trouble!!
[Miscellaneous Android Development] nannycrick:
Okay. Root is successful. Recovery installed correctly BUT.....TWRP 3.0.2 is reporting error 255 when I try to flash a zip. (Error 255 is internal storage fail.)

Is twrp recovery failing to flash to system?
[Miscellaneous Android Development] nannycrick:
TWRP issue....update..

Fixed the error, (wouldn't flash anything, wouldn't make a backup)

by flashing the twrp recovery 2.8.7.0 from the OP boot & recovery download link. It works. Did my backup, flashed Xposed v87-sdk21-x86.zip and, ViperAtmos+Beats 5.5 from Guitar Hero, and Walkman player from Ibanez!

Also got AdAway running too!

Now if I could fix the sucky WiFi issue, life would be perfect!

As an added note...my HTC phone had the same problem with TWRP 3.0. went back to 2.8.7.0 and the issue went away. Running a custom deodex 6.0 rom in my phone, and still run TWRP 2.8.7.0 without problem!

I guess 3.0 still needs work?!
[Miscellaneous Android Development] zefie:
Do you have "ft3x17.h"? Because I couldn't find it anywhere.

Edit: Nevermind, got touch working with the zenphone2 drivers. That was tricky. ACPI doesnt define it so you have to manually do so in platform data. Thats the short description. I'm about 90% through on this custom open source kernel. once I get it a bit more where I want it to be, I will post a git repo.
