Use it at your own risk! It is unknown if it causes any damage to the screen yet. I'm currently testing it for a month now, no issues yet. It should work in any MIUI or non MIUI based ROMs (Don't flash it on any Q ROMs, it is reported that it will bootloop!).

-Download the attached dbto.img, Lanthanum System Toolbox.apk file, install the apk, then open it
-Select partition settings from the hamburger menu
-Select dtbo, make a backup of it (Export image)
-Select dtbo again, click flash image, and choose the dtbo.img file
-Reboot

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

If you want to go back to default, flash your backed up dtbo image file.

I'm currently using this mod, I'm gonna report back if I found anything unusual. Feel free if you have any questions.

Edit: The screen has a greenish tint in the dark gray colors, if the brightness is set to low.

Edit2: After using for 2 days, I couldn't find any problems, no screen burnin, or anything so far, only the greenish tint on darker areas. Some users are reporting that they don't have this tint at all.

Edit3: I'm using it for a month now. No issues so far (besides the greenish tint)

I found this mod here: https://www.miui.com/thread-24921430-1-1.html
Many people from that forum using it for 3-4 days, and they didn't report any damage to the screen.

All credits go to the MIUI forum thread creator.

I found that this may be caused by the file manager u use. I'm on Pixel Experience and using the default file manager made it crash. But when I used Xiaomi file manager, it worked.


But besides, wow, this smoothness is amazing. Works just great in Pixel Experience ROM 😉

what is the model name of the panel used in the mi 9? Maybe at the vendor page we can find out if it's officially designed to run with 84 hz.
Awesome work so far!
