I think there is a modified superSU out there named SuperSU-v2.79-SR3-cappu.zip found it in Russian MULTI ROM forum MI Pad 1/2/3 MI PAD 3 page 2 . Post#20 click on BOT (I am not allowed to post link in forum)
I have some serious problem with this instructions. I followed all but fail to get my MI Pad 3 Rooted
The strange thing is when flashing super su the message is boot img missing -aborted every time and
unmount of /cust failed; no such volume . Without root i have no use of this device.
So first flash the xiaomi.eu-zip and superSU after the TWRP installation and format resize of data partion. All looks fine but no ROOT. After that fastboot flashing all image files of china developer rom and try again... Now I have done that 3 times and starting to wonder if there is another way to obtain ROOT?
Now after latest attempt it is not possible to copy the files at all the USB memory is not recognized so I am stuck with china developer rom not rooted or just TWRP and no boot
Any help for enable usb otg?
I just figured out that it is a modified superSU out there:SuperSU-v2.79-SR3-cappu.zip but now I am not able to flash anything from TWRP . USB OTG is not working.
I finally managed to fix everything by trying little different variations of the instructions of this thread.
So what worked for me was:
1. Download the China Stable Fastboot Rom from en.miui.com
2. Unpack the file and open a terminal in the "images" subfolder.
3. Enter the Fastboot mode and connect your Tablet with your PC.
4. Check if your Tablet is successfully connected by typing "fastboot devices" in your command line.
5. Enter
- fastboot flash system system.img
- fastboot flash boot boot.img
- fastboot flash recovery recovery.img
- fastboot flash cache cache.img
- fastboot flash userdata userdata.img
6. After that, you can reboot your device typing "fastboot reboot".Restart the unit and then again enter fastboot.
7. Enter:
fastboot -w
I skipped this step: fastboot erase system
I skipped this step: fastboot format system
fastboot flash recovery twrp.img
8.Download xiaomi.eu-zip
9.Download SuperSU-v2.79-SR3-cappu.zip found it in Russian MULTI ROM forum MI Pad 1/2/3 MI PAD 3 page 2 . Post#20 click on

10.Boot into TWRP (Volume up + Power on, hold the Volume up-Key until TWRP boots)
11.Wipe only dalvik and cache at this time do not format data.
12.Flash the custom rom from and the SuperSu from step 8 and 9 otg usb.
13.Wipe Dalvik and Cache and reboot to system.
14.Do initial setups as normal.Do not install anything big because the memory is not yet formatted so you are right now limited to internal memory only.
15.Reboot into TWRP
16.WIPE -> Data -> Repair or Change File System -> Resize File System (Only Data tick box shall be filled in)
17.Reboot in to system.
It worked for me and I have no idea why my usb memory was not recognized that was the reason why i did as I did in step#7
SuperSu is working well.
A warning! Do not try to install Magisk! I ended up with a dead unit but I did find a much helpful guide that saved my day. I did not take out my battery and it worked anyway just keep th volume down button as long as needed to flash 5-10 min ... Google: "97373-how-to-unbrick-soft-and-hard-bricked-mediatek-mtk-android-phone"
So after that unbrick experience I followed the steps 1-17 again.
