[Xiaomi Mi CC9 / Mi 9 Lite Guides, News, & Discussi] DGAMER8484:
Hi everyone!

In this thread I want to share all the mods that I’m using on my Mi 9 Lite. After a lot of search, I made this phone really fast, and I really recommend to give a try.

You need:

- Mi 9 Lite with unokcked bootloader

- Patience

First, the ROM. What rom for a low supported device? Also MIUI 12.5 is good and great but not for Mi 9 Lite (at least now). AOSP roms are badly translated and have ugly design in my opinion. So need to find the best MIUI 12 from Xiaomi.eu. The latest version is the 20.12.9, but a few peoples reported that in this version there are no effects in app animations. 20.12.2 was great, and almost bugless*, so you can download that here.

I highly recommend to do a clean flash for starting over everything. (Thats why need patience)

1. Initial setup & Settings: After you are ready, finish the setup wizzard CAREEFULLY (you need to turn off “User experience program” and “Send diagnostic data automatically” options), login to your accounts and go to settings, because we need to set a few things here. First, if you using gestures, turn off the pill, because this cause some lags when switching between apps. Turn off wifi assistence, NFC, Pocket mode, printing services, privacy protection. You can use vibration, Anti-flicker mode or others but if you don’t use anything from the upper options, just turn off.

2. Auto start & Background activity: Now download every apps that are you using, also update system apps, restore your contacts, notes, and other things. Go to settings > apps > permissions > autostart. Go to options and click to “show system apps”. Now turn everything off. After you are ready, go to Battery & Performance, click the settings icon, go to App battery saver, again show system apps and choose Restrict background activity for every single app that you don’t need in background. (You can chose a few apps for No restrictions, like Messenger, Whatsapp, etc). Uninstall super wallpapers.

3. Magisk and Greenify: Turn off your phone, install Magisk. Now you need to install Greenify and set up the app to work in the background (you can turn off the notification). Install Termux.

4. Modules: Do not install touch improvement, performance boost, cpu clock, etc modules, because these will not do anything just more microlags. I used all of them, even in the same time. All trash. Install Universal GMS doze, Busybox, Debloater (you can find these two in the app). And check the Magisk lag fix theard because magisk can make some microlags in the system.

5. Debloating: Xiaomi and other brands using it’s own apps to give more enjoyable experience. Many apps are not just great but the phone can’t even work normally without them. BUT this not mean that you need to keep all. There are also china apps like Mi Pay even in the .eu ROMs. These apps work in the background without launching them and you can’t uninstall or disabling. This is why we need debloater.

Go to termux and type the following commands:

- su (this command give permission to super user)

- debloat (this will launch debloat module)

You can uninstall multiple apps with numbers and space between. (15 50 3 5, etc)

Be very careful! You can broke the system, and you need to reinstall magisk, which need time! I highly recommend to read more here, or follow my uninstalls.

6. Updating system apps: Xiaomi has made many bug fixes in their apps. In this Telegram group you can easily search for system apps that are also including the new features. (Except clock, sleep time option will disappear if you update the Clock app). But you need to install Google Package Installer before that because Xiaomi’s package installer not allow to update any system app. Don’t forget to update the SystemUI controls app too, to get the new MIUI 12.5 volume bar :) .

7. Now you are ready! Set your favorite options, wallpapers, ringtones and enjoy the fluid MIUI experience with long lasting battery life and fast app opening speed. Wait 2 days for best results.
