This guide works for Mi MAX Helium [MI Max Prime 64/128 GB] also with locked bootloader and TWRP. Should also work for MI MAX Hydrogen [MI Max 32 GB] provided the ROM described in step 1 below has to be Hydrogen MIUI ROM.

I will explain the steps in the manner as described below :

Step 1 : You need to download the recovery ROM Zip from the below mentioned link :

Link for MI MAX Hydrogen [MI Max 32 GB] :

Step 2 : Extract the downloaded Recovery ROM file through winrar, winzip, 7z etc to any folder

and open the extracted ROM Folder in Windows Explorer [for those without any PC extract the ROM and open the extracted ROM folder in any file explorer and delete all files inside the folder "FIRMWARE"

[this does not update the firmware since for those with locked boot-loader and TWRP, this should keep the phone booted with TWRP and Locked Boot-loader]

Step : 3 Now zip all the files in the extracted ROM folder and rename the zip to MIUI9.zip [or whatever name you may fancy] and you are ready to go.

Step 4: copy the zip package as described in Step 3 [MIUI9.zip or whatever name you have saved] to the internal memory of your phone. At this point please download SuperSU 2.82 zip and copy to your phone's internal memory as you will be needing it.

Step 5: Boot into TWRP Recovery and go to Wipe > Advanced Wipe > select the FOUR partitions namely : data, system, cache and davlik cache and wipe them clean

Step 6 : Go to "Install" menu of TWRP Recovery and install the ROM file MIUI9.zip or whatever name you have given to the zip file as described in step 3 which you have copied to your internal memory of the phone as described in step 4

Step 7: These steps are very vital. Please pay attention and do as described.

Failure to follow these steps might result in boot-loop or soft-bricked devices.

Go to Wipe Menu of TWRP Recovery select Wipe > Advanced Wipe >> select the TWO partitions namely : cache and davlik cache and wipe them clean

Step 8 : Go to "Reboot" Menu of TWRP Recovery and select Recovery option. This will reboot the phone back to Recovery Mode in TWRP Recovery

Step 9 : Once rebooted back in TWRP Recovery - Go to "Install" Menu of TWRP Recovery and install Super Su 2.82.zip as downloaded and copied to your internal memory of the phone as described in step 4. This will ensure that DM Verity and other force encryption are patched.

Step 10 : Go to "Wipe" Option of TWRP and again select Advanced Wipe and wipe clean the TWO Partitions - Cache and Davlik Cache.

Step 11 : After wipe is complete please reboot back into TWRP Recovery by selecting Reboot > Recovery - Do not reboot back into system as the ROM file contains the file "Recovery from boot.p" which will wipe away TWRP Recovery. Hence, if you want to keep TWRP Recovery reboot back into TWRP Recovery

Step 12 : Select "Mount" Option and mount system partition in TWRP if it is not already selected/mounted.

Ste 13: Now select "Advanced " Option in TWRP Menu and select "File Manager". Go to system and delete the file "Recovery from boot.p" and then after deleting this file , you may reboot into system and enjoy rooted MIUI 9 on TWRP Recovery.

I hope you might enjoy stock rooted rom miui 9 on mi max. Enjoy and Cheers !!!!
