| How to Get Rid of MIUI by Installing Project Infinity-X on Redmi Note 12 Pro |
Okay, so if you're like me and you're just tired, straight up exhausted, of MIUI's constant ads, bloatware, and that laggy feeling even on a decent chipset, then you're gonna want to hear this out. I finally ditched MIUI on my Redmi Note 12 Pro and flashed Project Infinity-X instead, and honestly, it feels like a completely different phone now. Smoother, cleaner, no random ads popping up in my file manager (yeah, MIUI actually does that, lol).
I know flashing a custom ROM sounds scary if you've never done it before. Trust me, my hands were shaking the first time I did this on my own device too. But once you understand the process step by step, it's really not that bad. So let me walk you through exactly how I got rid of MIUI for good and got Project Infinity-X running smoothly on my Redmi Note 12 Pro.
Before we get into it, though, I gotta drop this warning because it's genuinely important: modifying your system software like this voids your warranty, and the process is gonna completely erase all your internal storage. So please, for the love of everything, back up all your important stuff: photos, documents, your girlfriend's pics, whatever you can't afford to lose, before you touch any of this.
Step 1: Prerequisites and Downloads
Alright, let's start with what you actually need before diving in, because trying to flash a ROM without having everything ready first is a recipe for a bricked phone, and nobody wants that.
Unlock Bootloader Request: The first thing you need to do is head over to the Xiaomi/HyperOS Mi Community app and apply for bootloader unlocking permission. This isn't instant, by the way — Xiaomi usually makes you wait a few days (sometimes up to a week) before they approve it, so get this request in early. Trust me, waiting around for approval is the most annoying part of this whole process, so don't leave it till the last minute like I almost did.
Set Up Your PC: While you're waiting for that approval, go ahead and install ADB and Fastboot drivers on your computer. These are basically the tools that let your PC communicate with your phone during the flashing process, so you can't skip this part.
Grab the Right Files: Now here's where you need to be extra careful. Download the correct Project Infinity-X ROM zip file specifically made for your device code, which for the Redmi Note 12 Pro 5G is ruby. Downloading the wrong device code's ROM is one of the easiest ways to brick your phone, so double, even triple-check this before downloading. Alongside the ROM, you'll also need a custom recovery like TWRP or OrangeFox, plus the correct target device firmware for your specific model.
Step 2: Unlocking the Bootloader
Once your unlock request finally gets approved (congrats, the hardest part of waiting is over), it's time to actually unlock your bootloader.
Start by putting your phone into Fastboot Mode. You do this by holding down the Power button and Volume Down button together while your phone is off, and holding until you see the Fastboot logo pop up.
Next, connect your phone to your PC using a USB cable, then open up the official Mi Unlock Tool. Sign in with the same Mi account you used to request the unlock, and hit the unlock button. Give it a few minutes to process, and your bootloader should now be officially unlocked.
Step 3: Flashing Custom Recovery
With your bootloader unlocked, we're now moving into recovery territory. Open up a command terminal on your PC, making sure you're inside the folder where your ADB and Fastboot files are located.
From here, run this command:
fastboot flash recovery recovery.img
This flashes your chosen custom recovery (TWRP or OrangeFox) onto your device. Once that's done, run this next command:
fastboot boot recovery.img
This boots you directly into your custom recovery environment, which is basically your new control center for the rest of this process.
Step 4: Flashing the Custom ROM
Alright, now for the actual exciting part: flashing Project Infinity-X itself.
Once you're inside your custom recovery (TWRP or OrangeFox), navigate to the Wipe section, then select Format Data. It's gonna ask you to type "yes" to confirm, since this action wipes your internal storage completely, so go ahead and type it out exactly as prompted.
After formatting, transfer both your firmware zip file and the Project Infinity-X ROM zip file onto your phone. You can do this through your PC using a cable, or however you're comfortable moving files onto your device while it's in recovery mode.
Once the files are on your phone, head to the Install option within recovery. If your device requires a base vendor firmware flash first (which is often the case with Redmi devices), flash that zip file first. Once that's successfully flashed, go back into Install again and this time select your Project Infinity-X ROM zip file to flash it onto your device.
Step 5: Final Setup
You're almost there, I promise. Once the ROM finishes flashing, go back into the Wipe menu one more time and select Format Data again. I know it seems repetitive, but this second wipe clears out any encrypted storage partitions that might cause bootloops or errors if left untouched.
After that final wipe, go ahead and select Reboot System. Here's the part that tests your patience — the first boot after flashing a new ROM always takes way longer than usual, so give it a solid 5 to 10 minutes before you start panicking that something went wrong. I remember sitting there staring at my screen thinking I'd bricked my phone, only for it to boot up perfectly fine a few minutes later, lol.
What to Expect Once You're In
Once Project Infinity-X boots up for the first time, you'll notice right away how different it feels compared to MIUI. No unnecessary bloatware apps cluttering your app drawer, no random ad popups, and honestly, everything just feels snappier. You'll go through a basic setup process similar to any fresh Android install: signing into your Google account, setting up WiFi, and customizing a few initial settings.
A Few Extra Tips From My Own Experience
Honestly, the biggest thing I learned from doing this myself is patience. Don't rush through downloading files. Always double-check that your device code matches exactly, because flashing the wrong firmware for your specific variant can turn your phone into an expensive paperweight.
Also, keep your phone charged above 50% before starting this whole process. The last thing you want is your battery dying mid-flash, which can seriously mess things up. And honestly, having a backup phone on hand while you're doing this isn't a bad idea either, just in case something takes longer than expected and you still need a phone to use in the meantime.

And that's really the whole process, start to finish. It looks intimidating written out like this, but once you actually go through it step by step, it's honestly pretty manageable, even for someone who's never flashed a custom ROM before. Project Infinity-X gave my Redmi Note 12 Pro a completely fresh feel, and honestly, I don't think I could go back to stock MIUI after this. If you're tired of the bloatware and ads too, give this a shot. Just make sure you back up everything first and take your time with each step.
