China Tablet Adware and Malware issues

[r2j2612]

Hello,

I am basically a noob, who has tried every possible method to remove the china malware apps from the tablet my mom bought off from ebay. The tablet keeps installing some sort of app in the background every 10 minutes, named ASYSTEM, which then runs ads for porn or games or installs unwanted apps in the background and after an hour or so, the tablet becomes absolutely unusable.

Below are the specs of the tablet I copied using MTKDroid Tools:

Hardware : MT6582
Model : ZH960
Build number : K1001_SP_V1.1.0_171226
Build date UTC : 20171226-111133
Android v : 5.1
Baseband v: MOLY.WR8.W1315.MD.WG.MP.V39, 2017/08/09 14:49
Kernel v : 3.4.67 (twd@twd-server3) (gcc version 4.7 (GCC) ) #1 SMP Thu Jan 4 10:03:41 CST 2018

I have tried the MTKDroid tools and SP Flash tool, but everytime I try to select the "Recovery" option while trying to "Download" the rom image created from "Readback", it doesn't allow me to select the same.

Found 2 apps which has system wide permissions -


com.android.system.service
com.qsoc.rebootmgr.whhy
asystem, which gets auto installed as soon as the tablet is connected to the internet, and then starts running ads.

As for using flash tools, I have tried using Kingoroot, King root, iRoot, Framaroot and a lot of others which 'assured' root access, but failed at around 70-80% mark everytime. I have been trying to root this for about 1 month now to no avail.

I am literally at my wits end with this tablet, and am turning to the experts here for help. How can I Root this tablet and if possible, wipe the custom android and install another rom?

Please help a noob kindly

You will need to find some way to get that readback of the recovery and port a custom recovery. You risk brick with this.

It's the only way if the auto rooters have failed.

That is the issue. Whenever I use the SP Flash tool, it never allows me to readback the recovery or do anything with it. Its totally greyed out.
