Top custom firmware for Xiaomi: which ROM to choose

Owners of Xiaomi, Redmi and Poco smartphones sooner or later face the desire to squeeze the most out of their device. The standard shell MIUI or the new HyperOS is often overwhelmed with advertising modules and background processes that slow down work. It is at this point that custom firmware comes to the scene that can radically change the experience of interaction with the gadget, it is not just changing the picture on the desktop, but deep reworking of system algorithms.

Choosing an alternative operating system is always a balance between stability and functionality. Some users are looking for a clean Android without unnecessary apps, others are dreaming of an advanced camera or gaming optimizations. The custom build market is huge, and it is easy for a beginner to get confused by acronyms AOSP, LineageOS or crDroid. We will analyze which options are really worth considering this year.

Before you take action, you need to be aware of the risks. Any interference with the software code of a device is potentially dangerous. ⚠️ Attention: Custom software installation is always done at your own risk. The author of the article is not responsible for possible malfunctions in your smartphone. The right build can give the device a second life, whereas a mistaken step can turn it into a brick".

Why Xiaomi Owners Are Changing Stock Firmware

The main motivation of enthusiasts is to optimize battery life. Stock shells often sin aggressive but inefficient power consumption in the background. Castom builds, especially those based on pure AOSP code, allow you to significantly increase battery life. The smartphone stops warming, and the charge lasts significantly longer even when you use it.

The second important factor is speed and lack of advertising. MIUI is known for its intrusive ad integrations into system applications. Switching to a third-party OS removes that visual noise, making the interface more pleasant. In addition, older phone models that no longer receive official Android updates can work faster on custom than the first day after purchase.

And privacy is also a concern, and many users are concerned about the collection of telemetry and personal data. ⚠️ Warning: When installing firmware from unknown developers, there is a risk of data leakage. Always check the reputation of the builder on profile forums. Using proven open source projects minimizes these risks by returning control of the device to its owner.

Categories of custom assemblies: AOSP vs. modifications of MIUI

All the solutions available on the market can be roughly divided into two big camps: the first category is AOSP (Android Open Source Project) and its derivatives. It's pure Android, devoid of any shells from the manufacturer. These systems work very fast, look concise and consume minimal resources, but they often lack some specific features of the Xiaomi camera.

The second category is modified versions of stock MIUI or HyperOS. Developers take official firmware, cut out ads, Chinese services and add root rights or new themes, an ideal choice for those who are used to Xiaomi’s interface and do not want to relearn, but want a faster and cleaner system.

There are also hybrid solutions that try to combine the design of the Pixel with the functionality of MIUI. The choice depends solely on your preferences. If you care about the design and smoothness of animations out of the box, look towards AOSP. If you need all the chips of your native camera and settings menu, choose mods.

💡

Before firmware, be sure to back up all important data to an external medium or to the cloud, as the process of installing a new OS often requires a complete cleanup of the device’s memory.

Top Best Projects to Replace MIUI

LineageOS has been the leader in clean builds for years, and it's an open source project that supports a huge number of devices, including older Xiaomi models, and is famous for its stability and security, and if you want a set-and-forget system that will last for years without crashing, that's the best candidate.

For Google Pixel aestheticists, the Pixel Experience project (or its forks, since the original project was closed) is created, and these firmwares copy the interface, widgets and camera phone features from Google, and you get that "pure Android" with smart features like "Now Playing" and live wallpaper, but on your Redmi or Poco.

If you’re an advanced user and like to customize every little thing, look for crDroid or ArrowOS. ArrowOS is often called the fastest firmware for gaming smartphones due to the minimalism of the code. crDroid, on the other hand, has hundreds of settings, from icon shapes to low-power behavior.

Xiaomi.eu phenomenon: the best version of the runoff

Xiaomi.eu is not technically a custom firmware in the classical sense, as it is based on the Chinese version of MIUI. However, it is adapted for the global market: it cuts out advertising, Chinese applications, added Russian and Google services. This is perhaps the safest way to improve your phone.

Xiaomi.eu’s main advantage is that it is fully compatible with all hardware, NFC It pays for the purchases, and the wide-angle lens doesn't glitch. AOSP-So you don't have to look for camera patches here, you get all the drain functions, but without any extra garbage, and with built-in Root access as you wish.

Installing this build requires an unlocked bootloader, but it's been debugged to automatism, and for many users, it's the final point of the search: the system flies, the battery holds perfectly, and the interface stays in place, which is the perfect compromise between custom and runoff.

Technical requirements and preparation of the device

Before you start installing, you need to perform a number of mandatory actions: the first and most important thing is to unlock the bootloader. Without this step, installing any third-party firmware is impossible. On new Xiaomi smartphones, this may require a wait from 7 to 30 days after you attach an account.

The second step is to install a custom recavérie, most often it is TWRP Or OrangeFox. It's a special recovery environment that allows you to install firmware, backup and clean up memory. TWRP You will not be able to install the downloaded ZIP-archive with new operating system.

It is also important to make sure that you download the firmware specifically for your model. ⚠️ Note: The firmware from Redmi Note 10 installed on the Redmi Note 10 Pro is guaranteed to bring the device down. Always check the codename of the model. For example, the firmware for mojito is not suitable for sunny, although the phone names are similar.

Installation process: a short algorithm of actions

The process of flashing it is intimidating only for a beginner, but it's actually quite logical. Once you connect your smartphone to your computer in Fastboot mode and unlock it, you have to go into recap mode, usually by clamping a combination of volume and power buttons.

The first thing you do in the TWRP menu is to do a full backup, and then you clean up the Data and Cache partitions, which is a critical step: if you don't clear the data from the old system, the new system can run unstable or reboot permanently, and then you pick up the firmware file and start installing it.

Once installed successfully, the system will suggest restarting. The first run can take up to 5-10 minutes, as the applications are optimized. Don't panic if the phone is hanging on the logo - this is normal behavior for the first start of a new OS.

💡

The key to a successful firmware is to completely clean the Data partition before installing a new system, ignoring this step leads to 90% of all errors and cyclical reboots.

Possible problems and solutions

Even if all instructions are followed, it can be difficult, and most often users experience a “bootloop” (cyclical reboot), 9 out of 10 cases this is treated by re-entering the recoveries and cleaning the sections, including the Dalvik Cache, more thoroughly.

Another common problem is broken VoLTE or video calls. AOSP These features often require additional patches or are simply not supported by the operator on the custom. 4PDA or XDA, It is clearly stated which functions work and which do not.

It is also worth mentioning the problem with Widevine. L1. After unlocking the loader, the level of protection DRM fall off L1 before L3, what is loss HD-quality in streaming services like Netflix. L1 It is possible to use an unlocked bootloader, but it requires complex manipulations with key dumps, which is not always safe.
