It will not speed up your tablet, as it is just a storage device which is much slower than the internal storage.

The only two games I have had recently are Gamloft's GT Racing 2 Real Racing Experience and Asphalt 8.

GT Racing 2 runs very well on this tablet, but Asphalt 8 is slow and laggy.

I restored my two older tablets ROMs and flashed Magisk to test it.

Yesterday I Installed Asphalt 8, after not having on any of my tablets for 8 months or more. The newest version, released in December is even more bloated than the previous version I had and it just keeps getting worse.

I really don't play these game much, but really only use them as a real world benchmark vs using the AnTuTu benchmark utility.

By the way, Magisk was again updated today to V15.2 and after a couple of days is working very well on my two, older tablets.

If you ever decide to go the Magisk root, you must remove supersu with unsu.zip flashed in twrp, flash a copy of your original boot.img, before you flash the Magisk.zip. Then reboot and install Magisk Manager.

[MENTION=8126387]martyfender[/MENTION] i was really hopping by using a SD it would let me free up some of the internal storage and speed up the device some. As far as flashing Magisk I may do that in the future but not at the moment, the tablet is actually better speed wise. Iv done everything I know to do to this thing, my son is actually started using it now. I wanna thank you for all of your help and for answering my questions I really appreciate it.

One last thing, I would like to delete some of the bloat on his tablet, but I don't wanna delete anything important.

---------- Post added at 10:03 PM ---------- Previous post was at 10:00 PM ----------

I went into root explorer then system then app I deleted Basic day dreams. There are some more that I would like to get rid of. Do you have any suggestions?
[Miscellaneous Android Development] martyfender:
I have always used it as portable storage, because if you choose adoptable, you will have to permanently keep it in the device as it extends the internal storage.

I believe there are some apps that can't be moved also, if you use it as adoptable. Kind of like and adopted child, once you adopt, you can't easily get rid of it!

That is one of the reasons I use Apps2SD with portable storage.

If you start using Apps2SD and find that it works well for you, buy the pro version, it is only $2-3, as it has many great useful features not found in the free version like restoring broken apps to the external, etc.

https://xdaforums.com/android/apps-games/apps2sd-partition-sd-card-link-apps-to-t3122919

http://www.apps2sd.info/

Note, some of the FAQ's are outdated, you can no longer use Minitool in Windows to create the partitions properly for Android 6+ as it will not create the second, GUID metadata partition needed by Apps2SD. You can view those partitions in minitool, though. The standard Windows Explorer will only see your first, FAT 32 partition.

You must have put this ext SD card in your Window machine first to get a system volume information folder?

If you use Apps2SD, I would search the thread for

because I have seen people on that thread who have had problem moving app data file to external, the one I see all of the time is Whatsapp.

The only messenger app I have used is Telegram to correspond with the Lspeed author, for the Telegram Lspeed group and the Telegram Govtuner group.

I never moved it to the external.

In all fairness, I also have to point out the I have had problems in the past with Apps2SD on my 2 older tablets V1.1.1 and V1.2.0

After several weeks though, it is working flawlessly on my V2.1.5 and V3.0.4 tablets

On the V1.1.1 tablet the external card reader has apparently failed and may have had issues from the get go that gradually got worse to the recent (last week) point of total failure.

The V1.2.0 will sometimes lose the SD card mount after waking from doze and I have to eject it and reinsert it for it to mount.

I think in the newer versions of the tablet they may have fixed some bugs in the ROM and IFWI firmware. Of course, Nextbook has never released changelog or provided restore ROM downloads, let alone any real support. I emailed them weeks ago and they never responded.

By the way, in case you didn't know the tablet is manufactured in ShenZhen,China By Yifang Digital.

Efun is the US distributor.
[Miscellaneous Android Development] BigM69:
IV actually just awhile ago starting using apps2sd there is a lot to that app, I'm still trying to figure out how to move user apps, lol. I tried to move dolphin Browser and a few other user apps and it failed says insufficient storage, but I'm picking external when trying to move.
[Miscellaneous Android Development] martyfender:
I use Apps2SD's built in system app removal tool to remove system apps that cannot be uninstall the usual way.

I just did that yesterday on my 2 older, newly restored tablets.

A word of warning, you have to be really, really careful doing this because if you delete the wrong system apps you can make the tablet un-usable or even unbootable.

I only have removed Nook, Google Play Books Google Play Music, Google Play Movies and TV and VUDU. You can also remove language keyboards for languages you don't use.

Especially don't remove such things as google play, google play services and google services framework as Android and many apps need them for functionality.

I am being very conservative as I have majorly broken things in the past on my older Ares 8 tablet by trying to do what you are doing.

You can probably search xda and the web for a good guide.

In apps2SD you go to: link apps to sd card, let the app page load, press and hold on the app you want to remove, select uninstall. If you click on the three dot menu in the upper right you can choose multi select so you can choose several apps and once to delete. After deleting, you must reboot for the changes to take effect. there are several menu options in the upper right to show and hike by type such as all, user, system, etc.

Apps2Sd has many other great features such as an SD card speed testing app.

After using this app for 2-3 years, I finally bought the pro version of this great app, to support Vicky Bonick, the app author.

UPDATE 1/4/2018: have updated the OP with my newer, easier method to root this Device with either SuperSu in systemless Mode or Magisk, also a systemless root solution.

They will both patch your original boot.img so you no longer have to flash one of my modified boot.imgs. You still need the TWRP contained in those various archives I have on AFH (Android File Host), to backup and flash with.

I've also added a link at the end of the OP for my previous post about some apps that I find to be personally useful.

Quick question, i have Mode: NX16A8116K android 6.0, would using Linux make this easier? I am ready to call in a hit on B. Gates! :mad::mad::mad::mad:
[Miscellaneous Android Development] martyfender:
Easier in what way? you still have to use the terminal and enter adb and fastboot commands. I've done it both ways. I mostly boot into Linux Mint Mate and regularly use it in both adb and fastboot.

However, I initially had problems in choosing the correct fastboot package that contained all of the fastboot commands for our device. The top one listed in the software repository apparently does not. In Linux Mints software manager two are listed, one called Android-tools-fastboot and one called Fastboot. I had to use the second one.

For adb I chose Android-tools-adb.

What version of Linux are you using?

Under Linux you have to use the sudo command before the fastboot commands to run as root. For example:

sudo fastboot flash recovery Ares8A_recovery_twrp.img

Also you may

possibly

have to edit udev rules files to add entries for the Intel usb devices.

So no, it is not any easier on Linux vs Windows unless perhaps you are talking about getting the proper Intel drivers setup.

What kind of a problem are you having in Windows? I probably can help you.

Also, for future reference, please don't quote the whole OP.
[Miscellaneous Android Development] BluEyedHellion64:
well, windows 7 is just being a perverbial PAIN, as far as using ADB, i was actually considering putting Linux cinnamon on the my laptop, im guessing its just finding the right driver files, also

my tablet v3.04.MMB29M20170620.075926

model:NX16A8116K so what file for the twrp file would i have to use?, i already downloaded the 15 second Adb file listed on xda, i just need direction in getting the right recovery,, thank you so much in advance!

---------- Post added at 11:50 AM ---------- Previous post was at 11:39 AM ----------

Ok, thanks to you i found the file i needed for twrp!

---------- Post added at 12:28 PM ---------- Previous post was at 11:50 AM ----------

I hate being a pest, but do you recommend a stable ROM for this tablet? i enjoy playing Clash of Queens, but as it is this tablet has some serious lag issues, making game play tough and bp raising....i usually just like to root and de-bloat, but i think a more stream line ROM is needed ? Any thoughts? again, THANK YOU!!!
[Miscellaneous Android Development] martyfender:
You also need the Intel drivers I linked in the OP (Opening Page).

I only have one TWRP version for this tablet. They are the exact same in every file I host here. It sounds like you don't have the drivers setup properly. After you have installed the Intel drivers, you may need to go into the Windows device manager and confirm that the proper ones are chosen.

To confirm thatadb is working, when the tablet is booted into Android, from a Windows command prompt run as administrator:

adb devices

Your device should be listed

One of my tablets, for example is:

List of devices attached
YFGV0317037600 device

To confirm that fastboot is working, reboot the tablet into bootloader/fastboot mode then issue in the command prompt:

fastboot devices

Your device will be listed with a different number than above, for example, mine is:

CHTT011AC12A fastboot

You must have USB debugging enabled in developer options on the tablet and you must approve the security prompt that will pop up on your tablet when you enter the adb command the first time from your computer. Check the box on the lower left of that security dialog, also.

All of the above is explained in the OP.
[Miscellaneous Android Development] BluEyedHellion64:
Yes, i am downloading the twrp file as i type, think i can manage the ADB now, i just want all my files i need on my laptop...
[Miscellaneous Android Development] martyfender:
[MENTION=8842717]BluEyedHellion64[/MENTION] Even though adb should be installed system wide now, I still find it easiest to place the twrp file in the adb folder, which should be at C:\adb. Then in an empty spot in that folder, right shift click, choose open a command window here, to open the command prompt.

Supersu.zip or Magisk.zip, busybox.zip must be already copied to Your external SD or internal SD, so they can be navigated to and chosen, once booted into TWRP. Be sure to backup your original system, boot and recovery in TWRP first and I recommend then copying them to a backup location such as your computer or to an external drive, etc, before flashing root and busybox. Please let me know how it goes.
[Miscellaneous Android Development] BluEyedHellion64:
Yes, actually seen that in my researching this, and have it written down, my original problem was the adb was not creating a path and would not install at all, hence i had wrong file...! Dont think i will have this problem now.. thanks again!

See i recently tried to unlock my old HTC Desire because my beloved LG L2 beast died a sad death after 3 years of faithful service, God I miss that phone! Well, the HTC went the direction of a HARD wall, { poetic justice far as i was concerned, so my fiance fearing for his big screen bought me this tablet lmao (menopause and unlocking boot loaders really shouldn't mix) } Some things impressed me about it, price, screen res. the lag did not...Well i wont have a device i cant root, so here i am...:o:)
[Miscellaneous Android Development] martyfender:
I don't understand what you are saying about the path, unless you are referring to Environment Variables: System Variables: Path: C:\adb.

Did have to install them manually to C:\adb, the following files: adb.exe, AdbWinApi.dll, AdbWinUsbApi.dll and fastboot.exe?
[Miscellaneous Android Development] BluEyedHellion64:
that's the path i was talking about, beings i was using wrong files to begin with, the adb never installed, therefore no path in the environmental variable...

[Miscellaneous Android Development] BluEyedHellion64:

[Miscellaneous Android Development] martyfender:
My newest tablet is that same, V3.0.4, also and it does not have Android 6.0 on it, it has Android 6.0.1.

Did you read my updated instruction that I highlighted, big, in red, at the very top of the OP, stating updated intructions are at the bottom of my quick start guide link ?

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

To temp boot twrp, you have to boot the tablet into bootloader/fastboot mode, not from adb mode. When the tablet is booted normally, issue:

adb reboot bootloader

Hit the enter key on your computer.

Once booted into bootloader mode, where you see the green Android guy on his side, issue this in the command prompt to temp boot TWRP:

fastboot boot recovery Ares8A_recovery_twrp.img

Hit the enter key on your computer.

You should see a message that the image is being copied and was successful, on both the computer and at the bottom on the fastboot tablet screen.

Now in TWRP, first set the time zone and language in settings, then backup boot, system and recovery.

If you read my updated way to root this, you don't need to flash a modified boot.img to do it. You use the new, linked SuperSu systemless that I also linked in my new quick start guide at the bottom, to patch your boot.img.

I have not even released a modified boot.img for the V3.0.4 tablet, for this reason. If you mistakenly flash any of my other modified boot.imgs to this V3.0.4 tablet, you will loose sound and possibly wifi and bluetooth.
[Miscellaneous Android Development] martyfender:
I have revised my Quick Start Guide with updated information I left out concerning my new method to root this tablet, systemlessly, with your stock boot.img, instead of a modified one. See the bottom of the guide:

Once booted into bootloader mode where you see the green Android guy on his side, issue this in the command prompt:

ok, is there any info on rooting this device, i am greatly wanting to do a 1GB storage swap for RAM (swapping 1-2GB of the internal storage for 1-2 extra GB of RAM so that the RAM will match the 1.92GHz Intel processor
[Miscellaneous Android Development] martyfender:
What kind of apps do you run where you need that much ram? I think the device uses 400mb of zram like my original ares 8. The only memory intensive app I have on my newer device Is Gameloft's GT racing 2 Real racing and it runs fine with the default 400mbs of zram.

On my original ares 8 with android 5.1.1, I have the game moved to my 2nd ext4 partition, on my external SD card and it runs great from there. I used Apps2sd by Vicky Bonak. to do this. I also have a hispeed microsd card, also. And, of course, you need root to run the app, which I have on the old ares 8.

[Miscellaneous Android Development] martyfender:
Yes, I actually had real racing 3 installed on my original ares 8 and it ran slow on that device. that is why I have never tried it again. I have never tried a real swap file on it to know if you would benefit or not. Apps2sd has the ability to create a 3rd, swap partition that may be of benefit to you.

Root has not been released for this device for you to be able to benefit yet. Still a lot of things to work out for this to happen yet. Stay tuned.

[MENTION=2472806]vampirefo[/MENTION] I download a different adb and fastboot package from the Linux software update manager and now I see all of the commands that I see in windows for unlocking and unlockability.

One nice thing I noticed on both of the ares 8a's that I have now, is that the sound volume is considerably louder than the sound on the original ares 8 with the newest ported 5.1.1 rom.

I have greenify installed on all of them with additional permissions granted through adb on the two 8A's and I think maybe the battery life may be better with aggressive doze off in greenify's settings. Not 100% certain yet, though.
[Miscellaneous Android Development] martyfender:
Thanks to [MENTION=2472806]vampirefo[/MENTION] I have twrp and modified boot.imgs for both the old and newer ares 8a with activation required. I am waiting for his approval to be confirmed before I release it, though.

[Miscellaneous Android Development] TurnaboutSavage:
[MENTION=8126387]martyfender[/MENTION] So how would you get the root, would you just apply the update through the stock recovery and it would give you twrp?
[Miscellaneous Android Development] martyfender:
I have gotten approval to release this from the original author. It will take some time to prepare documentation for it and am waiting on approval for a developer account on android file host to serve the files.

The release will include a custom TWRP recovery, boot images modified by the author and updated by me to remove dm_verity and a system mode supersu.zip. There will be boot images for V1.1.1 of the tablet and V1.2.0 of the tablet. You will know if you have V1.2.0 of the tablet because it requires an activation code to be entered from your purchase receipt, the first time you boot the new device.

After flashing the custom recovery and boot image through fastboot, in bootloader mode, you would gain root access by flashing supersu.zip in twrp recovery.

I am only aware of 2 versions of this tablet. If there are any other versions, please let me know, because I could modify the boot.img of that device also, if provided.

What version do you have?

I have flashed both versions, to each device and they work on each, but if you use the wrong boot.img for the device, it will work but you will loose sound. I have tested several scenarios.
