[MENTION=8473566]SgtWhoop[/MENTION] What version of the tablet do you have? go to settings about tablet and scroll to the bottom: build number. It is the first few numbers for example: V1.2.0.

Did you flash my files corresponding to your version? If you flashed the wrong version, that could cause that problem.
[Miscellaneous Android Development] SgtWhoop:
Thanks but I've figured it out, almost bricked it but flashed the wrong version of items but all good now! Great guide! Thanks!
[Miscellaneous Android Development] martyfender:
That is good to hear. What version do you have and what was the wrong version you flashed, just out of curiosity?
[Miscellaneous Android Development] martyfender:
The upload for versions 1.1.1 and 1.2.0 has been replaced with version numbers in the boot.img for clarity and a newer version of supersu system mode.

Hi I want to root my Ares 8A v1.0.8.
[Miscellaneous Android Development] martyfender:
[MENTION=8479483]Shiboshi[/MENTION] The twrp will work on it but my modified boot.imgs are for newer versions of the tablet. If you follow my directions in the OP (opening page) to unlock your bootloader and temp boot twrp, you can backup the boot.img, system and recovery to an external sd card. Don't backup data in twrp, because data has to be deleted to create a new, unencrypted one after the new boot.img is flashed. So if you have any important files in data, copy them to your computer through mtp, to back them up first.

Zip the backed up boot.img, which will be named: boot.emmc.win (

not

the boot.emmc.win.md5) and upload it to a file sharing site or google drive and provide me with a sharable link to download it. I can modify it and then share a link with you. Does the 1.0.8 version also have android 6.0.1 on it, or is it 6.0?

Of course, you must have the proper drivers, fastboot and adb working on your computer and bootloader unlocked, as outlined in the op, to do the above. I know the twrp I have should work because the author of it created it based on a 1.0.8 tablet version. He just never released his boot.img to the public.
[Miscellaneous Android Development] Shiboshi:
Thanks for the quick reply. My Android is 6.0.1. It is my first time Rooting. Just for trying I already did the method in OP(I know bad idea). Now my WiFi is not working. I will try to do what you ask me. Thanks
[Miscellaneous Android Development] martyfender:
Your wifi is not working because you flashed a newer boot.img. The system and boot.img must be the same version, or you will loose wifi and sound and maybe bluetooth.

I hope you backed up your original boot.img in twrp before you did this. That is the one I need to modify for it to work with your tablet.

I don't, as of yet, have a 1.0.8, original boot.img. So that is why I hope you backed the original up first. The newer one you flashed will do me no good as it is for a newer tablet.

Let me know if you have a copy of the original or not and I can modify it for you if you do have it.
[Miscellaneous Android Development] Shiboshi:
Don't have it.
[Miscellaneous Android Development] martyfender:
The OP clearly stated to make a twrp backup of boot, recovery and system before you proceeded. Unless someone provides a 1.0.8 boot.img for me to modify, I can't do anything.

I have a 1.2.0 twrp backup rom listed in the op, you could try. I can't confirm that it works with the 1.0.8 tablet, but it should. I have a 1.1.1 tablet, and I am running the 1.2.0 on it. If you do decide to try it, do a backup in twrp of your current rom boot, system and recovery to your external sd card, before proceeding.

You must unzip it and copy it to the twrp folder on your external sd card with the proper folder hierarchy, for it to work. Several previous posts outline the folder structure. If the backup is not in the proper folder structure, it won't be visible in twrp when you choose restore from the twrp menu.
[Miscellaneous Android Development] Shiboshi:
The only thing I saved was all my games ROMs. If I find the v1.0.8 I'll let you know. Thanks for your help.
[Miscellaneous Android Development] martyfender:
I've only seen one other 1.0.8 user and he gave up on the tablet because he couldn't get adb and fastboot to work in windows 10, so he never provided me with a boot.img. I would try the 1.2.0 backup rom. A link is posted in the OP.

Problems with Activation Code - DiSa

Good day friends and thanks for uploads this files to flash our tablets, I have a Nextbook Ares 8a released on March 2017, I was successfully flashed the 1.2.0 version of boot to try it, my problem is that my tablet request for an "activation code" on first time boot. I don´t know whats the trouble about it, can you help me to resolve it please. I have the twrp recovery installed to install any backup of any tablet that have a firmware version that don´t request for an activate code.

Thanks in advance.
[Miscellaneous Android Development] martyfender:
The activation code is on your receipt. Also linked some posts back is a website you can get the code by entering the disa code from the sticker on the box to get it. So you flashed the boot.img only? Did you use the fastboot commands to delete userdata and cache as outlined in the OP?

Is it a 1.2.0 tablet? If it was released in March, it may be a newer version than 1.2.0. My 1.2.0 rom has a release date of February. I have the boot.img for 2.1.1 and 2.1.5 tablet versions, linked in the OP.
[Miscellaneous Android Development] Djvvb1:
Problems with Activation Code - DiSa

Yes, the trouble is that I don´t have the receipt or invoice to see this code, I never save the invoices or receipt....The version of tablet have before install the 1.2.0 was a 2.1.1,

Thanks for repply.
[Miscellaneous Android Development] martyfender:
Then why didn't you flash the 2.1.1 boot.img?, or do you mean you flashed the whole 1.2.0 backup rom?

I don't also understand why you didn't activate it on first boot before flashing any of my files. The disa code is on the box. Also, did you flash twrp permanently or did you temp boot it?
[Miscellaneous Android Development] Djvvb1:
Problems with Activation Code - DiSa

Yes sir, i flashed the whole 1.2.0 Backup trought twrp recovery, but It still request for the activation code. :(

Thanks for fast repply
[Miscellaneous Android Development] martyfender:
Also, I am not sure if the 1.2.0 rom works properly on a 2.1.1 tablet. I don't have a newer tablet to test it on. I do know though, that the 2.1.1 rom doesn't work properly on my 1.1.1 tablet. it looses sound and wifi has problems.
[Miscellaneous Android Development] Djvvb1:
I was never able to enter the system, when I turn on at first time the tablet it request for the code but I don´t have the receipt, in the box have the DiSa number but when i try retrieve the activation code at www.getyourcode.com it says "The activation code you have requested cannot be displayed at this time."

I was flashed permanently the twrp.
[Miscellaneous Android Development] martyfender:
It states that it displays codes only for items purchased. Did you boot into fastboot and format userdata and cache as outlined in the OP?

When I disabled by ad blocker and entered the disa code example they have on their site, it brings up an activation code. That code could be tied to your original rom though, I'm not sure. The disa number is supposed to be on the back of the product also. I'm not sure about the nextbook though as I returned the 1.2.0 tablet I had.
[Miscellaneous Android Development] Djvvb1:
Problems with Activation Code - DiSa

Yes sir, the tablet let me able to make this.. fastboot flashing unlock - fastboot flash boot Ares8A_120_boot.img - fastboot format userdata -

fastboot format cache.

Ohhh so if Nextbook tied to your the original rom tablets, we can try flash my tablet with your original rom to after flash it insert the code that the code you uses to disable the lock.......what do you think about it??
[Miscellaneous Android Development] martyfender:
I don't understand your English.

You should be able to enter the code on the activation screen of the tablet.

I don't have the code for my rom. I returned the 1.2.0. I've never had to enter any code on my 1.1.1 tablet or with the current 1.2.0 rom. I only had to enter the activation code on the 1.2.0 tablet I returned. I did not save the code.

I believe the activation is hardware or firmware based. I'm not sure. And I really don't understand why you didn't activate it when you first got it. It clearly shows on the box that it requires activation on first use. That should have been done first thing.

Did you do a backup of your original roms boot.img and system in twrp as outlined in the OP? That is the rom you should be using on that device and your activation code should work on that rom.

As far as unlocking the bootloader, that is something entirely different and you should only have to do that once.

As far as getting the activation code, I had to disable my ad blocker in firefox, ublock origin. In chrome I had to disable scriptsafe, ublock origin and privacy badger. Disable any ad blockers you have and restart the browser.
[Miscellaneous Android Development] Djvvb1:
Problems with Activation Code - DiSa

I never had this code because I bought the tablet on Ebay, I have the box with the DiSa number but the page does not let me see the activation code, I have the Original ROM thanks to the twrp backup that you says in the OP, I thought this would work, I think it must worked without the code after flash another Rom versión.

Thanks for repply
[Miscellaneous Android Development] martyfender:
I edited my post above about disabling ad blockers. What browser are you using and what ad blockers do you have? ad block plus, ublock origin, no script, script safe, privacy badger or other? It worked in both browsers when I disabled all of them, both in firefox and chrome. I tested with the disa number they have on the site because I don't have the real one anymore.

I tested several times and sometimes it doesn't work. It worked for me again when I closed the page and opened a new one again. And are you doing it on a computer or another device? I did it from a desktop computer.

If you bought it on ebay they should have given you an activation code, unless they are stolen. Seems fishy to me. Walmart, where I work, is the only retailer I know of that sells them and, maybe Amazon.

If activation is hardware or firmware based, as I suspect, no, flashing a different rom would not bypass activation.
[Miscellaneous Android Development] Djvvb1:
I have Google Chrome with Adblock Plus and I'm on my Windows 7 PC, I think the trouble is that the maybe this tablet is a stolen device :( , I'm afraid I got ripped off!! :(
[Miscellaneous Android Development] martyfender:
Disable adblock plus and restart your browser. then open a new page then enter the website. Or try firefox without any addons installed. Also disable any host file add blockers is you don't have the windows default ones.
[Miscellaneous Android Development] Djvvb1:
Problems with Activation Code - DiSa

I tried it:

Disable adblock an restart the browser - No way - the same msg "he activation code you have requested cannot be displayed at this time. "

I was install the Mozilla Firefox - No way - the same msg "he activation code you have requested cannot be displayed at this time. "

I tried on microsoft Internet explorer 11 - the same msg "he activation code you have requested cannot be displayed at this time. "

[MENTION=8484641]Djvvb1[/MENTION] a user uploaded a twrp backup of the 2.1.1 to me. I haven't posted it yet because I had asked him to upload a supersu systemless patched boot.img to me because I have no way to patch sepolicy in the boot.img. When one flashes supersu in systemless mode it patches the boot.imgs sepolicy to be permissive. I had also asked for this from the 2.1.5 tablet owner, but no, they were quick to upload their original boot.imgs and once they got what they wanted they have not helped me.

I can see why vampirefo gave up on helping people with this tablet and the original ares 8. Once they get what they want they can't even honor a simple request. My unpatched sepolicy, boot.img works if one uses systemless supersu.

The original 1.1.1 and 1.2.0 boot.img I uploaded have sepolicy patched because they were patched by vampirefo with the same tools he used to build twrp. He wants nothing else to do with helping with this tablet, as he put it, rather bluntly today.

And I can't blame him because there are many ungrateful users out there.

I may quit supporting it myself.

If you are able to get detailed instructions on how to do this from [MENTION=6751620]HERPDERP202[/MENTION] I recommend you have your original rom on the device, ie. system and the 2.1.1 modified boot.img and use the official, latest, supersu systemless installer: https://download.chainfire.eu/1122/SuperSU/SR3-SuperSU-v2.82-SR3-20170813133244.zip?retrieve_file=1

If you get it to work, please let me know. I need a supersu systemless, patched boot.img, if you can back up the patched, boot.img in twrp and provide a link to download it on a file sharing site or google drive. Just .zip it first. It is a reasonably small file for the boot.img, only.

Is this where you got your tablet?

https://www.ebay.com/sch/items/?_nkw=Nextbook+ares+8a&_sacat=&_ex_kw=&_mPrRngCbx=1&_udlo=&_udhi=&_sop=12&_fpos=&_fspt=1&_sadis=&LH_CAds=&rmvSB=true

If so, the little you saved, certainly wasn't worth the hassle of trying to get it activated. What did you pay for it?

The official, nextbookusa site only lists Walmart as a retailer to buy it. I wonder where the sellers on ebay get them? From the back of a truck in Shenzhen 518108, P.R. China, where they are manufactured by Yifang Digital? They should have given activation codes on your ebay purchase receipt, if they were legitimate, I would think. If they were used that may be a different story, but used ones, in most cased would already be activated.

I have never bought anything on ebay but I know bad computer memory is sold all of the time there as well as counterfeit sd cards with fake capacities etc. I was careful when I got my samsung evo card and it has been an outstanding performer in speed and reliability. I buy only from legitimate retailers.

Sorry, I am raving, but I get angry when sellers can get away with this crap. That is one of the many reasons I don't do ebay. Even counterfeit microsd cards have been sold on Amazon, as well as sub-standard computer memory.

Thanks

Problems with Activation Code - DiSa

I understood that the real reason that He could resolve this trouble is Uninstalling the Setup Wizard but I have some questions,

He says

1. I went into recovery and used adb sideload to edit default.prop to enable adb

I ask.... Whats sideload???

What i need to change on default.prop to enable adb??

2.Then after that i went into the system and comfirmed the rsa key and adb to launch the settings to log in google so then i went into play store using adb to uninstall setup wizard...

I ask ...How he could in to the system??

What's is the "rsa key"

How he could launch the settings to login google

How he could in to playstore using adb to uninstall the setup wizard???

Thanks
[Miscellaneous Android Development] martyfender:
You will have to ask him, I don't know either, as I have never done any of those things.
[Miscellaneous Android Development] martyfender:
[MENTION=8484641]Djvvb1[/MENTION] I believe changing these in default properties:

ro.secure=1 to:

ro.secure=0

and:

ro.adb.secure=1 to:

ro.adb.secure=0

but I would ask him.

I am not sure how he did because any modification to the default properties are overwritten early in boot. The boot.img ramdisk contains a default property that is loaded at boot, overwriting any changes you make on the device default property file. My modified boot.imgs have this modified:

ro.secure=0 instead of 1, but not ro.adb.secure=0 it has a value of 1.

Were you, by chance emailed a purchase receipt that could have the activation number on it, or a website that showed a purchase receipt? I have run out of things to try to fix this. Can you return it and order one from walmart.com? Is that available in your country? I am in the United States.

[Miscellaneous Android Development] dednotebook:
Nextbook version 1.1.0

My build is 1.1.0, How do I get build 1.1.1 or 1.1.2

Savage.exe sent me

Thanks
[Miscellaneous Android Development] martyfender:
When you go to settings, about tablet, the build number is V1.1.0? If so, I believe my 1.2.0 twrp backup in the OP should work. Keep in mind this will delete all of your userdata, so back up anything important to your computer and in temp twrp create a backup of boot, recovery and system to an external sd card, before flashing this. If it is for certain 1.1.0, that is one I wasn't aware of.

Then permanently flash twrp and restore this backup once twrp is flashed permanently. The files must be unzipped in the proper twrp folder structure: TWRP/BACKUPS/NX16A116K/2017-07-10-23-29-03_V1.2.0MMB29M20170216.211208/ to your external sd card or internal.
[Miscellaneous Android Development] dednotebook:
I will try it sometime this week. It is build 1.1.0 android version 6.0.1 , i am just trying to get rid of the encryption - too slow for my liking. Thanks for the help
[Miscellaneous Android Development] martyfender:
Actually i must have been tired when i read this there is no 1 1 1 or 1 1.2 you have the same 1.1.0 tablet i have so follow directions in the op and be sure you use the 1.1.0 boot. Img. Formatting userdata and cache must be done in fastboot per my directions to disable encryption. You could also flash 1.20 also, if you want.
[Miscellaneous Android Development] dednotebook:
Awesome, you rock thanks for the help!
[Miscellaneous Android Development] dednotebook:
A couple of questions, is the recovery img ever used? or is that to put it back to normal? I am a n00b when it comes to tablet flashing, what's the difference between 1.1 and 1.2? Is there any clearer instructions on backing up the phone? also, do you have that link to disable encryption? Thanks again for all the help
[Miscellaneous Android Development] martyfender:
No, I have never used the original since twrp is so much better. yes, it is to restore the original, only. There are no apparent differences between the two. The original 1.2 tablet and newer requires an activation code from the purchase receipt. It is only an antitheft measure. I bought that additional tablet, pulled the rom and reflashed the original recovery and returned it. When 1.2.0 is flashed on the 1.1.1 tablet it does not require activation. I suspect the activation is built into the Intel firmware built into the newer tablets. You should be able to find info on using twrp with a search, my guess is even with photos or youtube videos. It is pretty simple and straight forward.

Boot into it. Go to settings and set time zone and other setting. Hit the backup button, choose storage to save to, check boot, system, recovery if this is your first backup. Don't check data as it needs to be deleted the recreate a fresh, unencrypted data partition after formatting it in fastboot (userdata and cache).

Here is a link that has a screenshot of the main screen:

https://en.wikipedia.org/wiki/TWRP

Just read my directions thoroughly posted in the OP (Opening Page)

Setting up the drivers, fastboot and adb seems to be the biggest problem for many users. Read my directions on how to test if it is set up properly or you won't be able to proceed with the bootloader unlocking, backup and flashing steps.
[Miscellaneous Android Development] dednotebook:
I have read a lot on the rooting but I have a question again, what do we edit to remove encryption?

You said:

"the tablet will be re-encrypted upon boot, without encryption option removed from the bootloader."

I am not sure what to do at this point, any help would be much appreciated -- I am almost at r00t Thanks again marty
[Miscellaneous Android Development] martyfender:
Flashing my modified boot.img disables encryption. The fastboot commands delete the userdata and cache:

fastboot format userdata
fastboot format cache

The above commands deletes the old, encrypted, data partition.

After data is deleted with the above commands and the tablet is rebooted with my modified boot.img, a new, unencrypted data partition is created on booting up. After deleting userdata and cache, the first boot will take some time. When I redid my tablet last week this first boot took about ~5-6 minutes. That is how long you will see the Nextbook boot animation before the tablet boots into the android setup screen. it is not in a bootloop. You must then setup android again.

Adb commands are run when android is normally booted.

Fastboot commands are run when when booted into bootloader mode (fastboot mode).

Also, here is a link to my quick start guide:

https://xdaforums.com/showpost.php?p=72970060&postcount=82

For clarification, temp booting twrp is only to backup your original boot.img, stock recovery and system.

After doing this, I recommend permanently flashing the twrp image.

In supersu settings check: Enable su during boot, Trust system user, Enable pro, relaunch supersu app, enable full content in logging. I also enable: clear logs after to never.

In android settings, security, I enable unknown sources.

In settings, accounts, setup your Google account. I have never set up a credit card. I download free apps.

In play store settings, I disable auto update of apps, as I prefer to have the choice of whether to update or not. For example I have a couple of apps where an older versions works better for me.

I also recommend doing a full twrp backup of boot.img, system and data after flashing my boot.img, supersu and setting up android. I would suggest doing this before downloading any apps from the playstore.

Here is also a link to a twrp flashable busybox I recommend over versions on the play store:
