Lenovo Tab M8 (FHD) (TB-8705F): How to root?

2020-02-13, 10:55 AM

Hello Everyone,

I am using my Lenovo Tab M8 (FHD) (TB-8705F) as a monitor to control a Mavic 2 Pro drone.

When connected to the controller unit it drains the inbuilt battery of the controller, which significantly decreases operation time. I enabled developer options and under "Default USB Configuration" I selected "File Transfer". However, each time the DJI GO4 app is launched this setting is over-ridden and it starts charging the tablet.

There are a few apps available that can turn off charging if the device is rooted.

I searched all over the internet and could not find a way to root my Lenovo Tab M8 (FHD) (TB-8705F).

Please suggest any links on how to go about this process.

This device is not yet supported with TWRP or LMSA.

Some of the other processes I found need the stock-ROM, but no-one has uploaded a stock-ROM yet anywhere.

So I looked at how I can make a stock-ROM. To use those method I have tried to use MediaTek SP Flash Tool (ver 5.1944.10).

Still NO-GO. It does not support MediaTek Helio P22T Tab Octa-core 2.3G platforms yet.

Now I am in a bind. Please suggest an alternative way to root this device.
