Hi,
The part that no one explain in that post is how to root
To root X98 Air II
download toolbox from: https://drive.google.com/file/d/0BwX…ew?usp=sharing
unzip the file
open a cmd and open the directory where you just unzip the toolbox
cd C:\Libraries\Downloads\Toolbox
in that directory there are some .bat files
run ADB_shell.bat
after that run ROOT_me!.bat
If successful root the tablet, now you can dun Link2SD
and all will work. SuperSU will be installed in your tablet
Now the market is working for my too!
u saved me .really noone was explained how to use that toolbox.thanks
I can’t seem to reach the dowload page following the above link… can anyone verify this please?
You can use X98 Toolbox to root any X98 tablet (X98/Air 3G/II).
Download it from here: http://d-h.st/9RX
Extract the package, double-click on 1_Toolbox.bat, connect your tablet to the PC and press ‘E’.
Need help… after finished rooting, system reboot and now my touchscreen doesn’t response at all. I can’t even touch the screen to unlock the display… did my x98 just brick? desprately need help here…
ok.. i re-run the rooting and this time after the system reboot, the tablet is functioning nomal again. My play store is also working now… thanks!
no ” 1_Toolbox.bat” file.
i have fixed the problem with the play store after updating to 4.4.4.
Thank you so much!
It always stops at Dameon started succesfullly and nothing happens… Any ideas?
I had the same problem. I turned on USB debugging in Settings->Developer options and restarted the rooting procedure and it worked for me.
None of these links are working!
i wonder if the new models featuring dual boot are suffering the same crashes with google Play. Does anyone have heard about such issues with the new models?
The links from Frontier provided are malware
After following the teclast update methode playstore still crashes. Did anyone solve this problem in another way?
Malware in what way? This is always a possibility with any rooting tool that originates in China.
Malware in the sense that my PC classes it as malware. Also the link is non longer to the same play services play store and link2sd apps. Its an exe file instead.
The files are hosted on one of those sites that tries to trick you into downloading malware. Click on one of the links and if it downloads a .exe file, delete it and use the other (correct) link. You should get a .rar file, as long as you don’t click on the .exe you should be fine.

I had the same problem so checked some Chinese bbs. It seems Teclast didn’t comment on the root cause, just asked users in China to send back the tablet to repair….wonder how I can do that because the postage is huge because I’m not in China.
