Warning! DO NOT flash Samsung OTA's! They may brick Your device! If You end up flashing one anyway, just use EDL mode or fastboot to go back to stock firmware.

Sorry guys. I forgot to mention that You need latest China Dev firmware. I've been using it with China Dev for entire day and it runs really well. So try to flash China Dev first. Also I was extremely tired while writing the guide so check it out again. Forgot about one step. Sorry! (24 hours without sleep). You have to flash dm verity disabler (it should have fbe disabler built it) after flashing vendor patch. And then everything will be perfect

Using this on regular WiFi Mi Pad 4 (not plus) and everything works flawlessly but not face recognition, I think that might have something to do with the Tab S4 having an iris scanner.

    So guys! Galaxy Tab S5e came out. And it has OneUI based on Pie and stuff. It also has similar CPU to the one that we have. So once we get MIUI Pie. I'll port OneUI from Tab S5e, I'll also use easier flashing method with it (TWRP).

    And some sad news.. RIL will probably never work. I've been trying to fix RIL in OneUI in OP6 and it's extremely difficult and might be impossible to fix. But tablets are mostly used with WiFi so hopefully majority of the users will be fine with that.. (Or let's say this way, once I'll fix RIL on OP6, I'll fix it here too :) ).

    Finally some progress with my own Pie vendor. Daily driver ready but impossible for an average user to flash..

    I'm waiting for Xiaomi to release official Pie vendor. Current custom vendors that are available just don't work properly so yeah. And there's also a problem with init which is pretty difficult to solve. I just found out that Tab S4 has Pie now. So we can definitely use it for a lot better base. But lack of proper Pie vendor is still a problem.
