Many users, when they first encounter the world of custom firmware and modifications for Xiaomi smartphones, stumble upon the mysterious term "Raw Xiaomi" or "Raw ROM." There is confusion: what is it, why is it needed and whether it will turn your phone into a "brick"? In fact, it is a fundamental approach to software that radically changes the experience of interaction with the device.
The concept is based on the rejection of the heavy shell MIUI or HyperOS in favor of stock Android. It is not just a change in the design theme, but deep processing of system files, removing parasitic services and optimizing the processor. If you are looking for a way to speed up an old gadget or just want to get the experience as close as possible to the Google Pixel, then the information below will be key for you.
Unlike standard updates that come in the air, installing the Raw version requires a deeper dive into the technical aspects, a process that requires an unlocked bootloader and superuser rights (Root), which automatically removes warranty from the device. However, the result is often worth it: the device starts to work noticeably faster, and battery life increases by 20-30%.
The essence of the concept of Raw Xiaomi: the difference from stock MIUI
To understand what Raw Xiaomi is, you first need to understand what standard firmware is. The MIUI shell is a powerful add-on above the Android core, containing hundreds of services, visuals and background processes. It's beautiful and functional, but often redundant. The Raw version is a skeleton of a system, cleared of everything superfluous, where every byte of memory is powered by performance.
The main difference is optimization: in standard firmware, many services (e.g. Mi Cloud, Mi Video, Mi Music) run automatically and consume resources even if you don't use them. In Raw builds, these components are cut at the system library level, which frees up RAM and reduces the load on the processor in standby mode.
Also worth noting is the difference in getting security updates: Xiaomi’s official firmware can be updated every few months, while custom Raw builds are often based on the latest versions of Google’s Android, providing security patches almost immediately after they are released.
⚠️ Attention: Installing Raw firmware is not a routine procedure. Unlike simply updating through the settings menu, this process requires the use of a computer, special cables and strict follow-up of instructions.
Advantages and Disadvantages of Switching to a Clean Android
Moving to Raw Xiaomi is always a compromise. You get incredible speed and cleanliness, but you lose some of the unique features that many people buy phones for, so let's break down the pros and cons in detail so you can weigh the pros and cons.
Among the undeniable advantages is speed: the interface becomes "live", animations stop slowing down even on budget models like the Redmi Note series, and obtrusive advertising disappears, which in some regions is embedded in system applications like "Conductor" or "Music".
But there's a downside to this: Camera is a sore topic for all custom firmware. The photo processing algorithms in MIUI Camera are tailored to specific hardware and software. Raw builds often use Google Camera ports (GCam) that produce great results, but may not work smoothly or support all camera modules (such as a macro lens or TV).
- 🚀 Performance: The system consumes less RAM, applications run instantly, and the interface runs smoothly even on older processors.
- 🔋 Autonomy: Due to the lack of background services and aggressive energy saving optimization, the battery holds the charge much longer.
- 🛡️ Security: Regular security updates from Google and lack of hidden Chinese telemetry services.
- 📉 Loss of function: May stop working NFC-Keys, Second Space, some game mode features and original widgets MIUI.
NFC is a special feature. Raw firmware often has problems emulating cards via Google Pay (or its equivalents). While the basic tag-reading feature is usually retained, contactless payment may require additional customization or not work at all depending on the model.

Technical requirements and preparation of the device
Before you start any manipulation, you need to make sure that your device is ready to install Raw Xiaomi. Not all smartphones are supported by the development community equally well. For popular flagships and popular models of the Redmi Note series, firmware comes out often and is tested carefully. For rare or new models, support may not be available.
The first and most important step is to unlock the bootloader, without which you will not be able to install customized Recovery (such as TWRP) that are required for firmware. Officially unlocking through the Mi Unlock site requires a wait of 7 to 168 hours (depending on the region policy and account).
You also need to make a full backup, and the Raw installation process involves completely clearing your internal memory (Wipe Data), and all photos, contacts, and apps will be deleted without recovery unless you take care of them in advance.
☑️ Checklist before firmware
Be sure to check the integrity of the downloaded firmware files. Often files are corrupted when downloaded, and trying to install a "broken" archive can lead to installation errors. Use checksums (MD5 or SHA256) if provided by the developer.
Comparison of versions: Global, China and Raw
Users are often confused by acronyms. To clarify, let’s compare the three main types of software you’ll encounter when using Xiaomi’s hardware. Understanding the difference will help you choose the best one for your needs.
Global ROM is the official global firmware version, which contains all Google services, has Russian out of the box and is optimized for international networks (Bands), which is the most stable, but also the most “heavy” option.
China ROM is a version for the domestic Chinese market, lacking Google services (you have to install them manually), contains a lot of Chinese software and advertising, but often gets feature updates before others. Raw firmware is the third way, the way enthusiasts.
| Characteristics | Global MIUI | China MIUI | Raw (Custom) |
|---|---|---|---|
| Availability of Google Services | Got it from the box. | No (installation needed) | Got it (GApps built in) |
| Interface language | Multilingual (includes Russian) | Chinese + English | Depends on the build (usually EN/RU) |
| Advertising in the system | Minimum/Switchable | Aggressive. | Absent completely. |
| Stability | Tall. | Medium (for non-China) | Depends on the developer. |
| Android Updates | Rare (1-2 years) | Frequent | Very frequent (up to 3-4 years old) |
The Raw version is worth it if you’re willing to put up with possible minor bugs to get the latest version of Android on a device that’s officially no longer getting updates.
💡
Use the "Device Info HW" or "AIDA64" app to know exactly the codename of your device. The firmware designed for the Redmi Note 10 (codename: mojito) won't stand on the Redmi Note 10 Pro (codename: sweet), even if the names are similar. It can break the phone.
Instructions: the main stages of installing Raw firmware
The installation process can be divided into several critical steps, and skipping any of them or disrupting the sequence of actions can lead to failure. Be careful and take your time.
First, you need to put the smartphone in Fastboot mode. This is usually done by turning off the phone and pressing the combination of the buttons Volume Down + Power until the logo with a hare or the inscription Fastboot. In this mode, the phone is ready to receive commands from the computer.
Then, using the console (ADB/Fastboot), you need to unlock the bootloader with the command fastboot oem unlock (or through the Mi Unlock utility), then the phone will be cleaned and rebooted. You can now install custom recavers, such as TWRP or OrangeFox.
fastboot flash recovery twrp-image.img
fastboot boot twrp-image.imgAfter loading into Recovery Mode, you must clean the Dalvik partitions / ART Cache, Cache, System and Data, and then you can start installing the system. ZIP-archive with Raw firmware and Google Apps package (if not built-in).
⚠️ Warning: Never interrupt the firmware process if the progress indicator is not yet 100%.Switching off the cable or battery discharge at this point is almost guaranteed to cause the memory chip to be soldered in the service center.
Possible problems and methods of solving them
Even with strict follow-up, it can be difficult, and most often users experience a “bootloop” (cyclical reboot), when the phone constantly shows the logo and does not load to the desktop, in which case re-enter the Recovery and full reset (Full Wipe) helps.
Another common problem is broken VoLTE or Wi-Fi Calling, which depends on a modem part (base) that may not be ported correctly from the old firmware, often by flashing the Modem or EFS partition from stock firmware, but this requires high skill.
If the phone is no longer defined by the computer (driver problem), try using another one. USB-The problem is often with poor-quality cables that don't provide stable data transmission, although charging is normally maintained.
- 🔄 Bootloop: Press the Volume Up + Meals, enter. TWRP And make a Wipe. Data/Factory Reset.
- 📶 No network: Check if the section is stitched Radio/Modem, compatible with your region.
- 🔒 Forgotten password: Raw firmware can have standard passwords for TWRP (often "12345678" or "password" - find them on the developer forum.
The 4PDA or XDA Developers forums contain branches for each model, which describe specific bugs and how to fix them.
💡
The most common cause of problems after installing Raw is incompatibility between the Android version and the bootloader version. Always check the requirements in the firmware theme header before downloading.
Where to look for verified firmware and documentation
Security of firmware downloads is the number one issue: downloading files from random sites or file sharing sites can lead to malware infection of the device. Use only verified sources with active moderation and user feedback.
The official XDA Developers forum is the gold standard, where developers post their builds, specify changelog (change list) and known bugs. For the Russian-speaking segment, the best resource is the 4PDA forum, where you can find not only files, but also detailed instructions in your native language.
Also worth paying attention to is the developers' GitHub, where many enthusiasts put the source code and builds there, which ensures that the file has not been modified by third parties after the author has published it.
