I copy the Ares8A_recovery_twrp.img in the folder where the adb and fastboot exe files are. I shift, right click on an empty place in that folder and choose: open a command prompt here. Once the command window opens, when Android is booted normally type:

adb devices

hit enter.

A security dialog should pop up in the tablet that you have to check a box then approve. You probably did not notice that dialog box pop up on the tablet and that is why it gave a device unauthorized message. Also you must have USB debugging re-enabled in developer options.

Your device serial number should show up.

The same goes when in bootloader/fastboot mode.

Type:

fastboot devices

hit enter, and your device should be listed, with a different fastboot, serial number.

As far as SuperSu goes You can copy it through mtp from your computer to a folder on the internal SD card and flash it in twrp from there. My V1.1.1 tablets card reader has failed so I have to do it that way.

I have a folder on the Internal SD named downloads where I put it and any other file I need such as the BusyBox.zip, SuperSu.zip, an older version of jrummy's root check app, SeLinux Switch, Mixplorer a copy of my original boot.img if I need to reflash it before again flashing Supersu systemless, etc.

I you are installing any downloaded apps other than from the Play Store you must go into settings: Security and enable the option to install from unknown sources.

Also there may be a way to flash SuperSu.zip from the computer, but I have never tried to do it that way to even look into if it is possible, or not.
[Miscellaneous Android Development] BigM69:
I hope this is the right twrp download

Ares 8A v2. 1.1 modified boot images

Unsigned-v211.img.zip
[Miscellaneous Android Development] martyfender:
The:

fastboot format userdata
fastboot format cache

will wipe even the contents of the internal SD card.

To preserve the internal SD card contents, just choose factory reset in twrp. Hit the wiped button and swipe to factory reset. This will wipe your data so a new, clean, unencrypted data partition can be created at boot without wiping your Internal SD card and hence, your downloads.
[Miscellaneous Android Development] martyfender:
Yes, the TWRP is the same in all versions. I don't have the necessary skills to build it my self and this one version that [MENTION=2472806]vampirefo[/MENTION] created from a V1.0.8, has worked with all versions of the tablet, so far.

Ok, so there is no need for the service fastboot commands right?

---------- Post added at 05:39 PM ---------- Previous post was at 05:36 PM ----------

After I download the twrp zip do I unzip? I know where to put it, I just need to know if I gotta rename the zip and put .img at the end. Also after I unzipped the size is 12.5 mb sound right?

---------- Post added at 06:00 PM ---------- Previous post was at 05:39 PM ----------

Sorry for asking so many questions. After I downloaded the twrp file it's showing the icon as a zip but there is no .zip at the end of the file name after downloading just .img but the file icon is a compressed file.
[Miscellaneous Android Development] martyfender:
You need fastboot to temp boot twrp with:

fastboot boot Ares8A_recovery_twrp.img

click backup, to backup your original factory rom, uncheck data as it will no longer be able to be restored. Now back it up.

Now to install TWRP permanently:

fastboot flash recovery Ares8A_recovery_twrp.img

From fastboot use the volume down button to select recovery then hit the power button to reboot to the permanent TWRP and choose wipe and swipe to factory reset.

Still in TWRP, click install, choose internal storage, (should be already if you don't have and external SD) choose the SR5-SuperSU-v2.82-SR5-20171001224502.zip, flash it and watch for the successful boot.img backup and patching.

Go back, use the down volume if it won't go back to the main twrp menu, click install, choose the Busybox-1.27.2-YDS-X86.zip, flash it. Now click the button to delete the dalvik cache and cache.

Now reboot, first boot will take a very, very long time as it has to create a new, unencrypted data partition. My last flash took 7.5 minutes where I saw the android boot animation before it rebooted to the android setup screen.

I have to get ready for work. I may be able to respond during my two breaks or dinner, but I will not be back home at my desktop until ~11:30PM EST.

This file you are having me download. . . its bigger than the ammount of storage my tablet has. My tablet only has 10GB of storage. Are you sure this is the right one for my tablet? Also is there a rooted 3.0.4 rom for it? cus i would like to have it rooted for the obvious reason being its so darn slow.
[Miscellaneous Android Development] BigM69:

After I flashed twrp perm do I keep read only or do I just only swipe to allow mods?

I had to reboot without installing SU and BB. When I was in twrp I looked for the zips and they weren't there. Twrp sees internal storage but isn't showing my zips. Im not sure why, I did format data and cache using twrp, should I have wiped data factory reset, then rebooted n set up device then boot back into twrp and flash the zips?
[Miscellaneous Android Development] martyfender:
When the tablet is booted normally and connected to your pc, you should see listed:

Intel Android adb composite device, I believe. See one of my recent posts for exact wording, az I am not at my pc. When botted. Into vbootloader/fastboot mode, you should se in thebdevice manager: Intel bootloader interface. Again a few posts. Back I listed it exactl fof windows. Did you download and install the Intel drivers linked in the OP? The OP has bettef info in setting up the drivers. Yours aren't setup properly.

[Miscellaneous Android Development] martyfender:
Is it possible you erased those files.?

This pages links or somewhat confusing and lack alot of info, but may help:

https://twrp.me/FAQ/

When connected to the computer with mtp, I open internal, create a download folder if it doesn't already exist, and copy files such as supersu.zip, busybox.zip, etc. Then when I boot o twrp, I hit the install button, select storage, and choose Internal storage, choose sdcard, or up a level if needed to see all of the folders in internal, choose Download, where I originally copied the files, then select the supersu.zip, to flash it, busybox.zip, etc. Of, course, I have simplified the file names in my example. Then swipe to flash.

I believe I have seen the files unavailable when I chose the wrong option, or wiped them from the device. That is one of the reasons I recommended choosing the twrp option to factory reset vs. delete data, because I have a feeling that choosing data may have wiped those files. Sorry, my memory is not so good. I do remember that when booted into fastboot, instead of twrp and choosing: fastboot format userdata and fastboot format cache, will wipe the internal folders, including your twrp backup, if stored there, instead of to an external SD card. I strongly recommend you get an external SD card to backup to and once you backup, copy it to your computer, as I lost by virgin V1.1.1 backup, back in July, due to an unexpected Ext. SD card corruption issue, caused by a third party reboot program that was not compatible with Android 6.

I have recommendef the factory reset option vs the fastboot commands becauce you have no ext, SD card. I do this with my V1.1.1 tablet, because the Ext. SD has apparently failed. I am currently using it to test new things, such as recent versions of Magisk, and betas, etc.

.
[Miscellaneous Android Development] martyfender:
The file is 3.1 Gbs on my Linux system. That is not that big. If it also had data it would be over 6 Gbs. No, I don't have a pre-rooted version, sorry. It should be the same version that your tablet came with, based on the info you provided me with.

Keep in mind that you will gain some space after userdata and cache is deleted.

You must do this for a fresh, unencrypted, data partition to be created. Hence my instructions in the OP to have a good backup of your userdata, if you need it before you proceed. You can use mtp to copy backup files to your computer, or use other means.

If you don't have enough space, that is an indication that you filled up the data partition with apps and files which will need to be backed up if you want to save them. That is clearly stated in the OP.
[Miscellaneous Android Development] BigM69:
So is this what I'm supposed to do??

If I perform a data factory reset in twrp will my stuff show up in downloads?

So I have unlocked the bootloader before I removed encryption.........i done it the way it says in OP.
[Miscellaneous Android Development] NyTR0S:
Well I was downloading the zip through my PC and I thought it was over 10GB I'm not home atm but ill CHECKx2 the file again
[Miscellaneous Android Development] BigM69:
The files I need are in my downloads folder in internal TWRP, but when I reboot to twrp and go to sdcard it's not showing up internal storage says (0)mb.

When I go to wipe screen after I click formate data then my internal storage says

Internal storage (10546mb)

I then do a backup in twrp once the backup is complete what do I do? I also formated user data and formated cache then rebooted and still couldn't see my internal storage. Do I need a physical SD card to be able to complete this?
[Miscellaneous Android Development] NyTR0S:
If it did not work I think and ADB push might work so try doing that instead of moving them when in the operating system
[Miscellaneous Android Development] BigM69:
YES FINALLY FIXED IT!

I'm in the process of doing a backup before I go any further. Now when I boot into twrp I can see all my downloaded files which are SR5 v2. 82-12242017 and busy box as soon as the backup is completed I'm going to flash superSU then busy box.

Also would be nice to change the DPI for its really hard for my son to see the small writing. So far I have installed nova launcher, greeny, Lspeed but don't know really how to use it, and kernel auditor.
[Miscellaneous Android Development] martyfender:
I had told you not to format userdata and cache so you would not delete the internal sd card, since you

don't

have an external SD card like most users get for the files and backups.

That is why I said only to factory reset in twrp, which will preserve the internal SD. And the flashing files, such as SuperSU, Busybox, etc are not put into the TWRP folder on the internal SD card, I create a folder at the root of the Internal SD called Download. I used that name because Android creates one with that name, vs what It is call on a Windows or Linux machine: Downloads. I don't believe the name makes a difference, though.

The actual TWRP backup files, on the other hand, will not show up in TWRP when you choose restore, if they are not kept in the exact folder naming structure as created on your device; examples:

/TWRP/Backups/NX16A8116K/2014-12-31--19-20-36_V3.0.4.MMB29M.20170620.075926

/TWRP/BACKUPS/NX16A8116K/2017-12-01--23-51-18_V2.1.5.MMB29M.20170327.212634

I am able to do all of this on my original, V1.1.1, where the external SD card reader has failed, using only the internal SD card storage.

I do recommend getting a good quality Micro SD card of at least 32GBs, such as the Sandisk Extreme Plus or a Samsung EVO. They are high speed reliable cards. We sell both of these at my Walmart, although stocks are low of the Sandisk Extremes, right now.

I've had trouble with at least two Sandisk Ultra Plus cards, so I don't recommend them. This tablet is supposed to be able to use up to a 128Gb card.

I definitely would not depend on an External SD though, as your only backup.

I have files backed up to my PC through mtp and stored in the cloud on GDrive, AFH and One Drive for my photos, as I was a professional photographer in the past.

I also needed a reliable, hi speed card because I use and app called Apps2sd, where a 2nd ext partition is created to move apps from your internal storage to your external to save internal space.

I don't uses it for most apps and never system apps, but for large games, which I rarely ever play.
[Miscellaneous Android Development] BigM69:
I already fixed it..

I'm just looking for a way to change the DPI so it'll stick, when I used DPI changers from gplay it would let me change it but it won't stick. Also I would love it if you would share your kernel settings and Lspeed settings with me so I can speed up his tablet.

Thanks!
[Miscellaneous Android Development] NyTR0S:
So I just have to ask is there no root available for my specific version of this tablet?
[Miscellaneous Android Development] martyfender:
Yes, if you root it yourself, you don't need a modified boot.img anymore if you flash the official, SR5-SuperSU-v2.82-SR5-20171001224502.zip which is systemless and it will patch your original boot.img. You need to flash it in TWRP. See my many, many previous posts for more info. Some info in the op is needs to be revised. I have to go to work.
[Miscellaneous Android Development] NyTR0S:
So you mean to tell me that all this time I could have just flashed Superuser and it would have worked? If that's the case then I really really hope that that one image that that one person sent me works

I'm not sure either I have to leave for work, or I would do a google search. Try playstore build property editors, look at the jrummy one first. also. It may require a patched boot.img to do it, also.

Yes, I own v1.1.1, v1. 2.0, v2. 1.5 and v3. 0.4 and I have done that now on every version.

Last night I flashed Magisk 15.5.to my v1. 1.1 tablet to test if it looses root for me like older versions did for me in the summer. So far, so good.

If you already have supersu, you have to remove it first by flashing unsu. Zip., reflash your original boot.Img, delete dalvik cache and cache, then flash Magisk. Finally install the Magisk Manager.

Is there a way I can contact you on either Skype or Discord so I can do this live because I have no idea where to find all the things necessary I'm not saying right at this moment but like within the next few hours or so

I have one of the backup images for the 3.0.4 tablet one of you guys sent me and I have I think the proper Superuser. Zip so all I need to figure out is how to use magisk that's why I'm wondering if I can talk to one of you guys live on either Discord or Skype.

I know I may be asking feudin too many questions but this is like the first time actually rooting my phone the way it was explained on this thread I come from kingroot where it's easy to root the phone but somebody told me that kingroot is garbage and to actually root the phone by and doing it this way but like I said before I completely ruin my tablet. As of right now I am using the 2.0.4 image but I like I said have no sound on either the speaker or headset so I'm hoping the 3.0.4 back up one of you guys sent me works completely but I want to talk to somebody live there Skype or Discord so I can actually figure out how to do this

[Miscellaneous Android Development] martyfender:
I think it is I suspected. In a root file explore you will see a file called default.prop. There is a line in it: ro.sf.lcd_density=160. It would appear that one can edit it to change the property. The problem is that it will be reset every time you reboot. In the boot.img there is a ramdisk where the default.prop is loaded at boot and it will replace the one in the system. The boot.img can be unpacked and the default.prop can be edited and repacked with changed properties. I unpacked my boot.imgs in the past and edited the default.prop, the fstab to remove encryption, the fstab.NXM882CAP_ES to remove dm_verity and the init.rc to make SeLinux permissive. Then I repacked them. I can do this for DPI also. but if it can be done in the build.prop file, I believe it would overide the default.prop. I will have to investigate this though.
