SuperSu Huawei MediaPad T3 7, no custom recovery.
Have root access thru magisk, but its weak and cannot install modules. Want to switch to Supersu but device not supported for custom recovery. Tools at my disposal are: adb & fastboot (pc and rooted terminal emulator), Flash-ify,
SDcard software update in project menu and via 3 button method. (Flashfire Pro leaves me with black screen and have to flash stock recovery to reboot tablet). Tablet is BG2-W09C128B023, EMUI 4.1, MM 6.0, Custom version CUSTC128D001, 1GB RAM, MediaTek MT8127 on 'about tsuablet' but MT65xx on multiple pc's that I have connected to.
