YouTube Tutorial: https://www.youtube.com/watch?v=BF4_hnKgjFA by Hovatek.

It's easy, download ROM U89C (have the link on the official page, 51cube.com).

Antutu does not work for me.

When you download the official firmware, you will need:

1. Install the official drivers of your U89 tablet.

2. Flashing your U89 tablet with "SP Flash Tool" [Tutorial for SP Flash Tool here: https://www.youtube.com/watch?v=LzyYXAflmOk]

3. Once you have flashed the latest version of your U89 tablet, connect your tablet to fastboot. He does not know how? it's easy, install this:

https://adb.clockworkmod.com/ for ADB Drivers.

https://xdaforums.com/showthread.php?t=2588979 for ADB & Fastboot in your Windows.

4. Well, once you have installed everything, connect your flashed tablet to U89C (the latest version) to your computer. In Windows, press "Ctrl + R" and type "cmd", press ENTER and type in your "terminal":

- "adb devices"

Your tablet will ask for an authorization to connect to ADB, now type in your terminal:

- "adb reboot bootloader"

Great, now in fastboot let's flash the patched bootloader:

http://www118.zippyshare.com/pd/S2Nb2x4D/10563/boot.img

Write on your Windows terminal:

"fastboot oem unlock" and press ENTER, on the screen of your tablet you will see some words in English, do not follow the instructions as they are wrong. Actually, to unlock your "bootloader", you need to press the button on your tablet: "VOL-" (Volume down).

On your tablet you will see something like "unlock pass", and on your computer you should type "fastboot reboot". Now your tablet is going to erase completely.

Perfect, it only remains to flash the "boot.img", for it once you have loaded your tablet again, write on your PC again:

"adb devices" & "adb reboot bootloader", in fastboot proceed to flash your "boot.img":

"fastboot flash boot boot.img" *

*A tip: type "fastboot flash boot" and drag the boot.img file to the "terminal" CMD.

Perfect, now write "fastboot reboot". Your tablet is rooted, install the Magisk Manager APK and enjoy.

You can share this tutorial, improve it or do whatever you want with it. It is translated from Spanish to English with Google Translator.

Tell me where I found official drivers of your U89 tablet ?

Is the new U89C antutu still not working, and whether there is a play store? Currently I have the version u89_v1.0_20170911 with the play store, and is there any difference between these roms?

Can I do root on the old version without flashing?

I tried to rooting the tablet apart from uploading a new rom. Going in turn according to your description, I press vol - and I have the message "unlock failed". What is going on ?
[Device Reviews and Information] rafaelkaiz:
Hello malojk,

You can flash with old version. Try VOL+, in my tablet is VOL-.
[Device Reviews and Information] malojk:
I tried with vol + and nothing at all. Any suggestions?
[Device Reviews and Information] rafaelkaiz:
it's very strange. Does it happen to anyone else?

can it be because on your android, in "developer options", you do not have marked "OEM unlocking"?

http://upimg.org/image.php?di=7O7A
[Device Reviews and Information] malojk:
Okbi will tray. Thanks.

Is the new rom u89 c better? Tell me where else will I find the official driver for u89? I have windows 7 and when I try to run spflash tool, the BEX error pops up
[Device Reviews and Information] rafaelkaiz:
Yes. although it does not include the Google Play store. but I will write a tutorial to install Google Play store in our u89. the drivers are in one of the u89c firmware folders.:)
[Device Reviews and Information] malojk:
Managed to!

I made root. Now, where to download magisk manager? Is it from the Play store ??
[Device Reviews and Information] rafaelkaiz:
Here:

https://magiskmanage r.com/Magisk/MagiskManager-v5.6.1.apk :)
[Device Reviews and Information] malojk:
Ok, it works. Thanks!

I still have a request. You could check if your "AMPERE" application works for me, it is still "0". I would like to choose the right charger for it. I know that 5V 2A. But not every charger gives so much. Although it has theoretical 2A. Recently, I was charging about 6h this tablet. It's a bit long. And what is the charging time for you?
[Device Reviews and Information] malojk:
someone had such a problem after taking root after each tablet reset, system settings are changing - for example, time, volume settings .... ?
[Device Reviews and Information] rafaelkaiz:
I have this problem with time.

I have fixed that edited the build.propio file. I'd love to make a copy of my system.img and userdata.img, since I think I've improved the rom a bit. I have also deleted the Chinese applications.

---------- Post added at 08:28 PM ---------- Previous post was at 08:25 PM ----------

Ampere:0mA
[Device Reviews and Information] malojk:
Can you help me ?? step by step :)

and home button does not work too and play store can not download apk after reset ....
[Device Reviews and Information] rafaelkaiz:
Probably the first firmware is better for you.

http://51cube.com/services?_search=U89

Or you can search on how to edit the time zone in the build.prop. To install the play store correctly, install these apk:

https://www.apkmirror.com/apk/googl...e-account-manager-6-0-1-android-apk-download/

https://www.apkmirror.com/apk/googl...ervices-framework-6-0-1-android-apk-download/

Link2sd: https://www.apkmirror.com/apk/bulen...-release/link2sd-4-0-13-android-apk-download/

and very important, with the program "link2sd" convert the services of google, account manager and google play store in system applications.
[Device Reviews and Information] malojk:
Currently I have the version u89_v1.0_20170911. I did not upload a newer version. After unlocking the bootloader, a lot of problems appeared. Do not you also have a home button and a notepaper bar? and why play store does not want to download the application?
[Device Reviews and Information] rafaelkaiz:
[MENTION=5773922]malojk[/MENTION]

What boot.img to used? if it is the one I uploaded to zippyshare, it is the boot.img of the version u89c. I have no problems with the home button.
[Device Reviews and Information] malojk:
I used it with 89c but I did not flash rom. I have this version which I had at the beginning. I noticed that the problem appears after every resession. Then only the factory settings will be restored and the u89 will start up for the first time. And if I make a restart again, all the problems come back; the home button does not work, the play store does not want to download, the settings are not remembered. Can it be the fault of this boot file. Img of the version u89c? Does it matter?
[Device Reviews and Information] rafaelkaiz:
It is probable. think that this boot file is not for that firmware version. It has many problems, to me the U89C version is good for me. I just had problems with the time zone, and it's easy to fix by editing the build.prop
[Device Reviews and Information] malojk:
In the end it worked. With flashing to 89c and I have root and everything works. Now how do you edit build.prop and change the time zone? Can anyone help?
[Device Reviews and Information] rafaelkaiz:
Hello, I feel the delay. You can edit the build.prop with this application:

https://play.google.com/store/apps/details?id=com.jrummy.apps.build.prop.editor

the lines to edit are:

persist.sys.timezone=

Default is Asia/Shangai

be careful because it is a delicate file.
[Device Reviews and Information] malojk:
What I have to put Instead Asia/shangai? I need gmt +01:00 i live in Poland
[Device Reviews and Information] rafaelkaiz:
I use Europe/Madrid, you can use Europe/Warsaw
[Device Reviews and Information] malojk:
Thanks for the help! How much battery do you charge from 0 to 100%? Is there any information whether there will be an update to Android 7.0
[Device Reviews and Information] rafaelkaiz:
I think so, alldocube keeps the tablet updated. and there is some tablet with the SoC mt8173 running Android 7. I have not checked how long it takes me, maybe 2 or 3 hours.
[Device Reviews and Information] damati001:
Hello Guys!

What is the difference between U89 and Freer X9?I asked the cube website if i could use the U89 firmware for this freer x9, they answered no..i dont understand.
[Device Reviews and Information] rafaelkaiz:
Hello [MENTION=4173254]damati001[/MENTION],

There is no difference. Alldocube Freer X9 is really called "Cube U89".

I do not understand why they said no, but maybe that person did not know that Freer X9 is the commercial name, the name "beautiful". The factory name is cube u89, the latest version u89c.

I have changed the resolution, 2K seems excessive to me. some games work much better, including F1 2016 (at 2k it's not bad, but it's not stable on fps).

For change resolución:

wm size 1200x1920

Dpi:

wm density 246

Looks good :good:
[Device Reviews and Information] malojk:
Where does it change? Build. prop or somewhere else? could you do a screen with your settings? Thanks!
[Device Reviews and Information] rafaelkaiz:
In a terminal. You can try this, is safe. If you dont like, add this for default screen:

wm size 1600x2560

wm density 320
[Device Reviews and Information] malojk:
Are you use "Terminal Emulator for Android " or another?
[Device Reviews and Information] rafaelkaiz:
Termux is amazing :D
[Device Reviews and Information] malojk:
No command ”wm" found in termux. ... Any idea?
[Device Reviews and Information] rafaelkaiz:
Try:

su

And commands.
[Device Reviews and Information] malojk:
Thanks.

what resolution I can still use? What about 2048 x 1536? Will be ok too?
[Device Reviews and Information] rafaelkaiz:
I have not tried it. 1200x1920 looks great.

For testing resolution, try Screen Shift app.
[Device Reviews and Information] malojk:
What app are you use to check fps in games?

How do you think if the lower resolution affects battery life?
[Device Reviews and Information] rafaelkaiz:
I do not think it affects the battery too much. I do not use any app, but I feel that some games are lighter. :)

I wish there was a twrp recovery, I would love to see android oreo on this tablet.
[Device Reviews and Information] damati001:
My tablet recieved today. I put it on charger, and while it charging i pushed the volume - and power button together. The "green android figure" showed up and bit later faded out, then my tablet wont start the System just light black, and now completely freeze and i cant turn off...I tired to hold all buttons (power + volume - ;power + volume + ;more than 1 min) nothing happened my tablet just went little light (dark)..im very sad beacause this is brand new tablet i could not even try it. Any suggestion maybe? Thank You!
[Device Reviews and Information] malojk:
hold the power button ( only this button) for more than 8 seconds. it should be reset
[Device Reviews and Information] damati001:
After 1.5 hour the display went dark. I put it again on charge (my charger is Samsung Galaxy 2 travel charger original 5V 2A beacause i have Galaxy tab 2), but nothing happened the battery icon didnt show up now and i cant turn on the tablet. I could use this tablet maybe just for 1 min till the "android green figure" showed up. Seems like the table is dead omg..i purchased from gearbest 200 dollar :((((
[Device Reviews and Information] rafaelkaiz:
If the tablet is black, wait until the battery runs out. Try flashing the tablet with the sp flash tool. install the u89c firmware. Good luck.
[Device Reviews and Information] damati001:
Thank you! I flashed the u89c and now working. :o

Hello. Do you have a problem downloading large games from the Play Store application. I want to download, for example, Mortal Combat X and a few others, and at the very end the download error pops up. Do you have that? U89C software
[Device Reviews and Information] rafaelkaiz:
Playa store and google apks are in system? Try link2sd for fix it.
[Device Reviews and Information] malojk:
Play Store, google services, google servicess framework, google acount manager are in system.

I do not know why this is happening. I cleaned the application data, snoozed the account in play, reset and continue the same. It is paused at the very end. You can try to download Mortal Kombat X and try is everything okay?

I can not delete play store in Link2SD for anything. I have version 9.1.23-all. Maybe if I uploaded an older version to help ...
[Device Reviews and Information] damati001:
Hello! I tired, but same problem here too..
[Device Reviews and Information] malojk:
Ok, I'm not alone :) If you find a solution let me know please. I also try ...

Probably every big game will not install ... but why?
[Device Reviews and Information] rafaelkaiz:
Ok guys, install my apks and try.

https://drive.google.com/folderview?id=1nbAYiP9zvG3JrUTb9CChfCEqCDVBoqw7

F1 2016 and others big games work fine.
[Device Reviews and Information] rafaelkaiz:
Add ".apk" in all files.
[Device Reviews and Information] malojk:
I installed and the problem is still there. Please download UFC apk and tray. By the time it has been downloaded but it has not been installed yet ...
[Device Reviews and Information] rafaelkaiz:
I have ufc in my tablet, very strange.
[Device Reviews and Information] malojk:
And exactly do you have those versions of files installed that you shared?

damati001

And how you are. Have you removed the problem?
[Device Reviews and Information] rafaelkaiz:
Same files, is a back-up.
[Device Reviews and Information] malojk:
I noticed that, for example, the UFC gets to the end but when it starts to install, an error pops up and breaks the installation.

When I download Mortal combat X which has approximately 1400 Mb, the download stops at the end, at around 1000 Mb, differently.

Any suggestions on what to do about it?

Other applications and games with smaller volumes install without a problem.
[Device Reviews and Information] rafaelkaiz:
Try to delete your google account and add it again.

or try this: try installing UFC, and when downloading, cancel the download. reinstall it
[Device Reviews and Information] malojk:
I tried to delete the Google account and all the same time. I also tried to download -> break and repeat again as you wrote. No changes. :(
[Device Reviews and Information] damati001:
Hello!

I tired many times installing the mortal combat x, but same problem like you. Later I installed those programs that rafaelkaiz suggested them (with link2sd integrated to system) and in play store grant premission to sd card, later succesfully downloaded and installed mortal combat x. One question: do you have guys on the tablet screen original protective foil or tempered glass?
[Device Reviews and Information] malojk:
Ok it works. Thanks. It was for an SD card!

I have on screen protective foil
[Device Reviews and Information] rafaelkaiz:
I do not use anything, before it was a sheet, but it was a little dirty from use. I'm glad we solve the problems. It is a bit difficult since it does not have any community, it would be interesting to create a FAQ, tutorials, etc ... but for now, the solutions and tutorials are in this thread.
[Device Reviews and Information] malojk:
Does your wifi turn off in the "standby mode" or does it work all the time?
[Device Reviews and Information] rafaelkaiz:

I have the option "never" but the wifi does not turn off when the screen is locked ... :)
[Device Reviews and Information] rafaelkaiz:

[Device Reviews and Information] malojk:
Another problem. From two days, the tablet only charges to about 94%, when it comes to picking up the load goes forward when the sleep stops loading. Earlier, it was able to handle up to 100% without problems. The same charger all the time! What could be wrong?

update: with SP-Flash v5.1728.00 it worked!!

Need help to install the firmwares with SP-Flash Tool.

I downloaded the original and the U89C Firmware.

So I used another SP Flash Tool, I had already on my Computer, but it sad that the scatter-file is not working.
[Device Reviews and Information] MattBratt68:
Still waiting for a tutorial to install gapps or to get Google Playstore running on U89C Firmware.

Problem is, that no update and no new app gets downloaded.

I tried different methodes to get the Gapps without root on the tablet, but no version can download apps or updates.

It always say "Downloading..." but nothing happen. !?

Could you translate it to English? please
[Device Reviews and Information] rafaelkaiz:
Actually I only explain how to root (is the same as in previous versions, there is a tutorial on previous pages).

And how to flash the firmware with sp flash tools. I have left all the necessary downloads (firmware, drivers, etc.)

http://www.xiaobaipan.com/file-21907448.html This is twrp, I did not create it. but it is installed, although it does not work very well.
[Device Reviews and Information] MattBratt68:
I tested the "Android 7.0" Version, but it is only a 6.0 Version. Someone only costumised the name and the nougat logo.
[Device Reviews and Information] rafaelkaiz:
How can you say that. It has the updated API, and all Nougat news. It's something simple to review ... [MENTION=594188]MattBratt68[/MENTION]

Among all the improvements, the best known: possibility of using applications in multitasking. In addition I have reviewed this firmware in full, and it is a port of a mt8176 tablet.

By the way, use a new Kernel. I think you have to know about it, when you say something. :)
[Device Reviews and Information] MattBratt68:
I tried to install Gapps over an APK, but the App only allowed me to install Gapps for 6.0 or lower.

And it looks very similar to the Marshmellow Firmware

Perhaps you are right. And I hope you are right, but I still have problems to get a working Playstore on this tablet.
[Device Reviews and Information] rafaelkaiz:
To run the google play store ... you must move the google apk to the system folder.

that is, use Link2SD and convert google applications into "system applications"

Open gapps for example, will not work since we do not have twrp.

Try this apks:

[Device Reviews and Information] MattBratt68:
I already tried Link2SD, but I don't know where to put your files?!

And they have no ending. Do I have to add ".apk"?

I'm flashing Android devices a long time, but outside TWRP and Flashtool I'm lost.
[Device Reviews and Information] rafaelkaiz:
yes, you add ".apk" and install it on your system.

to use link2sd and convert an application to "system application" you need to be root.

[Device Reviews and Information] rafaelkaiz:
It's just luck. You have to do this:

Press VOL-, repeat the process and VOL +, VOL-, VOL +. and flash the boot.img, all without restarting. If it's still not flashing, you repeat the process.

Good luck! Mediatek unlock is ..... **** xD:fingers-crossed:

reboot into bootkloadermode
[Device Reviews and Information] rafaelkaiz:
Thanks, it's something I knew.

By the way, do you know if there will be Oreo in Freer X9?

Alldocube has abandoned this tablet, it was the first tablet that it bought from that brand. I think it will be the last.

Next time, better a tablet from Google, or Lenovo, etc. At least they update their devices.
[Device Reviews and Information] MattBratt68:
I managed the installation of the Android 7- Version and Root inclusive working Playstore.

I just made all steps in a row, without rebooting. (Unlock VOL-, repeat VOL +, VOL-, VOL +. VOL - and than flash the .img)

The only problem I have now is, that the tablet is getting very hot, even with low Performance

P.S. I contacted Alldocube over Facebook, because of my Fake Brick, they told me how, and after it I asked about an official Nougat Version, but no answer till now.

So I think the same like [MENTION=7566912]rafaelkaiz[/MENTION] , there will be no update. First and last buy of a product from Alldocube, for me too!!!
[Device Reviews and Information] rafaelkaiz:
You can use a thermal pad. In our telegram group in Spanish, we have made a mod. the mt8173 processor gets too hot. Alldocube is trash, briefly. I expected more from this company, but it's just a company that brings out 500 tablets a year.

I managed to install my tablet with the rom posted by [MENTION=5780820]wangyiling[/MENTION] (:good:) above. I patched the boot.img and got magisk working. After that I installed play store and made it a system app with link2sd. Without it being a system app, it will only fail and crash.

The rom is not the same as the one [MENTION=7566912]rafaelkaiz[/MENTION] posted earlier. This seems to be built this summer. It says version U89A_V1.0_20180713 in the settings about the system. The one posted earlier seems to be from 20171011 according to the zip file. I have not tried that one.

My experience with this rom is that the system is more responsive, smooth and polished. I will test more during this weekend.

But, I have one BIG problem though; charging is very, very slow. This morning it was charged to 30-40 percent something and reported full charge was in 2 days. Maybe I will try the other 7.0 rom during the weekend.

I will report back later. :cool:
[Device Reviews and Information] rafaelkaiz:
I do not understand why U89A appears, for me it was U89. It's the same ROM, I've only re-upload It.

There are not two ROMs of 7.0, anyway I have already sold this tablet. a greeting.
