You should be having proper knowledge of flashing Custom ROM and how to Restore a phone if anything goes wrong.
Take complete backup before taking any action based on this thread. I am not responsible for any action taken by you.
I am just compiling all the information / files available on different websites into this thread, I have patched together with cyber spit, bubblegum, and tape, for a pretty much fully working Miui 10 PIE running rom. I have removed what I believe to be all of the bloat. Worked to modify a working miui pie vendor. Magisk 19.4 installer is all ready included as well as the modified boot for root access. The playstore installer is also included for a fully functioning playstore.
All Credit goes to respective developer/s included in the install.txt within the zip file. I request XDA moderator and or Developer of Respective files to let me know if I have forgotten to mentioned (give credit) their name in this thread. The Download Links are given directly from respective Developer/s.
You need the following two files to Test MIUI PIE on Mi Max 2 (Oxygen). This ROM recovery is ported from the Xiaomi MM3 with many patches and customized from various sources. This ROM maybe Stable enough for your daily use on Mi Max 2. I have access to two MM2 4/64 Global versions using a 1tb sd card one on At&t the other on Tmobile and all features I need are currently working.
1a. Treble Mi Max 2 Recovery 3.2.1 https://androidfilehost.com/?fid=5862345805528056270
1b. OrangeFox Recover 10
2. MIUI 10 Pie ROM ported from MM3.
Start your phone into recovery and Flash a Treble recovery, if already not flashed. Restart into Recovery.
Click Wipe then Advance wipe and clear System, Vendor, Boot, Data, Cache, and Dalvick cache. No need to wipe internals per txt.
Now Extract the Downloaded Rom files in Recovery backup folder. You should know where and how to Extract. (Use extract tool for android or pc then copy paste to recovery backup folder.)
Click Restore and Select System, Boot, Vendor and Swipe to confirm. Wait for restore to complete. If any errors, Reboot recovery and try again. Or Mount the System, Vendor, Boot and try again. After Restore completes Reboot. Please allow 3-5 Minutes for first boot.
Cell Service, Wifi 5ghz/2.4ghz, Bluetooth, Torch, Camera, Fingerprint, Sound, Auto Brightness, On Screen & HW buttons.
Now verified from users : LTE , Face unlock.
What doesn't work:
Some people can't log in to Xiaomi account ( I do not use it, So I can not verify either or).
I do not have dual 4G sims so I can not verify if its working. There may be potential signal problems for some user but I didn't faced in USA with Tmobile, Or AT&T operators.
Eye protection mode/ reading mode 100% does not work, But similar apps available within the play store.
Since base MIUI PIE rom is Chinese version no Gapps included. To get Play store DO NOT flash Gapps. Run Play.Store.Installer (Included)
Guys, this is a nearly perfect MIUI PIE package for our lovely Xiaomi Mi Max 2 (Oxygen).
If I missed anything in the above, kindly let me know to include. If you make any further updates / patches that makes this ROM more stable / perfect or enables new features, please don't hesitate to message me to include in this thread.
I have an old PC running windows with 8gb max at any one given time, So if you would like to make the recovery image into a flashable zip, I'd be happy to update/add it.
If you can afford it, Im trying to save for a computer from this decade, any help is appreciated
If you would like to use the boot, vendor, system, or any other files, All I ask is pass on the proper credits. With this we should be able to have a fully functioning android Q in the near future (Currently toying around with fair progress in the free time).

I am not including any Screen Shot as all MIUI Roms looks same and there is No major UI change based on Android Version in MIUI.
Best of Luck and Happy Flashing )
