Thread updated with TWRP-3.4.0-3.

Now the recovery.img is properly signed as the stock one. There shouldn't be anymore issues with ODIN.

    Code:
    ***Disclaimer*** 
    All flashing is done at your own risk!
    While nothing from this thread should break your device,
    don't come back here blaming anyone if it does!

    Always backup your current ROM (and/or keep stock firmware close by) before flashing.

    Big thanks to @ashyx and @jedld for the amazing work done for this device.


    Installation Instructions
    • If you don't have a custom recovery:
    - Download twrp-3.4.0-3-_mone-gtexswifi.tar
    - Reboot your tablet in download mode (power+vol-down+home) and connect it to your pc
    - Using ODIN load the downloaded file to the AP slot and press start
    - As soon the tablet start to reboot hold vol-up and home (don't let it reboot to system)
    - Now you should see TWRP-3.4.0-3
    • If you already have a custom recovery:
    - Download twrp-3.4.0-3-_mone-gtexswifi.img
    - Reboot into recovery mode

    - Reboot the recovery, now you should see TWRP-3.4.0-3


    If you require "root", just download Magisk (v18.1 as of February 2019) and flash it with twrp. You may need to install MagiskManager afterwards. No extra steps required.

    I've updated twrp to 3.1.0-1
    Nothing major just some little changes in the device tree.. before I was using sc8830 for the board name (chip), but the actual name is SC7730SW and the platform is sc8830. This should be the definitive build until major updates in the twrp source.

    Thread updated with Magisk-v12.0.
    No need to flash SuperSU with this version.
    SafetyNet Passed (see 1st attached picture). :good:
    If you reboot and open MagiskManager straight you'll probably get "Not rooted" error (see 2nd attached picture); just close the app, wait a bit, reopen it and everything should be ok.

    @_mone just one question. Are you planning/trying to make a custom ROM also for tm-280?

    I really hope so. Thanks

    Yes, I've already started.. but unfortunately I don't have much free time lately so it won't be ready soon.
