[MOD][ROOT] Really Overclock your MIX3 screen to 66HZ in MIUI Android P (Tested)

[HelloRickyLee]

Use it at your own risk! (Don't flash it on any Q ROMs）The dtbo.img is extracted from the Chinese version of miui 9.8.15,so you better use version 9.8.15 or later, If not worked you can try other rom. This Mod is tested and it worked for me，66hz is the most，more than 60hz will be slow because of the quality of the mix3 screen. this zip include 66hz for mix3

-Download the attached zip, unzip it
-Open TWRP
-Backup your dtbo partition
-Select the corresponding dtboxx.img,choose the dtbo partition,the flash it
-Reboot

You should see the changes immediately after the restart. It's way smoother than before.

If you want to go back to default, restore your dtbo partition backup or flash the dtbo60

It works. Thanks.
I tried it on the latest EU weekly 9.8.15.
The 66 hz works perfectly the rest not so much, Laggy and slow.

I'm sorry for asking this.
Isn't our Mix 3 screen already at 60hz? Does it have significant difference between 60hz and 66hz?

 

[Listy2021]

Stupid question maybe but can this be used with a GSI Pie ROM (Arrow OS)?

Not stupid lol so don't worry and it won't work on GSI only on stock

not Earth shattering but once you've done it right.
its pretty cool and you'll notice it after you enter the OS.
will also help if you tweak your system animations under developer options, make them a second or more.

Doesn't boot on pixel experience (pe plus)
