What gives the full firmware on Xiaomi Redmi Note 8 Pro: advantages, pitfalls and how to sew properly

The Xiaomi Redmi Note 8 Pro, released in 2019, is still popular with users thanks to the powerful Mediatek Helio G90T chip, 64-MP camera and capacious battery. However, over time, standard MIUI firmware begins to โ€œbrakeโ€ and updates from the manufacturer stop, in which cases many are considering the option of full firmware โ€“ installing custom or official global version of the software.

But what exactly does this procedure do? Is it worth risking stability for new features?

โœ… Advantages โ€“ from overclocking the processor to removing the Blaatware.

โœ… Hidden risks โ€“ why a smartphone can turn into a brickยป.

โœ… Step-by-step instructions for beginners (with a checklist).

โœ… Comparison MIUI, AOSP LineageOS - which firmware to choose for your tasks.

โœ… Answers to frequent questions - what to do if the network or camera does not work after the firmware.

If you're already experimenting, make sure you have a bootloader unlocked and a backup done, or it's going to cost 50 to 70 percent of the cost of a smartphone to recover. And now let's get to it.

1.What is a "full firmware" and how it differs from OTA-update

Full firmware is understood as replacing the entire operating system on the device, rather than simply updating individual components (as is the case with OTAs).

  • ๐Ÿ”„ Official. MIUI โ€” European, Chinese or European versions (e.g., transition from the European version) MIUI 12 on MIUI 14).
  • ๐Ÿ› ๏ธ Custom firmware - modified builds based on Android Open Source Project (AOSP), LineageOS, Pixel Experience or HavocOS.
  • โšก Port from other devices โ€“ for example, firmware from Redmi K20 Pro, adapted for Note 8 Pro (risky version).

The main difference from OTA is a complete reset and replacement of all system files, including the kernel and drivers.

  • ๐Ÿš€ Install a newer version of Android than Xiaomi supports (e.g. Android 13 instead of Android 10).
  • ๐Ÿงน Remove the built-in bloatware (Mi Browser, Mi Music, GetApps, etc.).
  • ๐Ÿ”ง Set up processor parameters, GPU and battery via Kernel Adiutor or FrancoKernel.

However, there is a downside: if you have incorrect firmware, you can lose IMEI, break NFC or Wi-Fi modules, and in the worst case, get a โ€œhard brickโ€ that does not turn on even in Fastboot mode.

โš ๏ธ Note: Redmi Note 8 Pro uses Mediatek Helio chip G90T, This means that the bootloader requires official permission from Xiaomi via the Mi Unlock Tool, rather than universal methods like fastboot oem unlock.

2.7 Real Benefits of Full Firmware on Redmi Note 8 Pro

If you are prepared for the risks, here is what you will get rewarded with:

  1. Castom firmware (for example, Pixel Experience) optimized for โ€œbareโ€ Android without a shell MIUI. It gives: ๐Ÿ“ˆ AnTuTu gains 10-15% due to background removal MIUI. โšก Instant interface response (no delays when opening Settings or Gallery). ๐ŸŽฎ Stable 60. FPS play (PUBG Mobile, Genshin Impact) without drawdowns.

New versions of Android

Official support for the Redmi Note 8 Pro ended on Android 11 (MIUI 12.5).Castom firmware allows you to install Android 12/13 with:

  • ๐Ÿ”’ Improved privacy (Microphone/Camera permissions disabled by default).
  • ๐Ÿ“ฑ Navigation gestures like on Pixel or Samsung One UI.
  • MIUI has built-in msa (Mi Statistics Agent) and analytics services that send data to Xiaomi, and the firmware removes it, and removes ads in the Browser, Weather and Themes.

See the full list of pluses in the table below:

AdvantageMIUI (official)AOSP (castomic)
Android versionUp to 11 (MIUI 12.5)Up to 13 (LineageOS 20)
Performance (AnTuTu)~280 000~310 000โ€“330 000
Advertising in system applicationsAye (in Browser, Weather)No.
Google Camera (GCam) supportPartial (patch needed)Complete (built into firmware)
Security updatesTerminated in 2022Monthly (from the community)

But it's not all that rosy. For example, custom firmware might not run Widevine L1 (Netflix has no HD), and the camera sometimes "glues" when shooting in 4K@60fps.

๐Ÿ“Š What kind of firmware do you prefer on Xiaomi?
Official MIUI
Castomic (AOSP, LineageOS)
Port from another device
I'm not asking for it.

3. Cons and risks: why not to stitch โ€œjust like thatโ€

Before you start using the SP Flash Tool or TWRP, consider the following:

  • ๐Ÿ“ถ Network problems: Not working VoLTE/VoWiFi (call-in 4G). Lost. IMEI (solved through Maui META, But not always. GPS (Due to the lack of mediatek drivers).

The most common mistake for beginners is the firmware of the wrong MIUI version. For example, if you install the Global ROM on a Chinese model (begonia instead of begoniain), the NFC will stop working, and Google Pay will issue the error "Device is not certified."

โš ๏ธ Note: Redmi Note 8 Pro cannot be flashed preloader through SP Flash Tool is a guaranteed hard brick. Use only methods that save the preloader partition (for example, through OrangeFox Recovery).

What if the touchscreen doesnโ€™t work after the firmware?
If the screen does not respond to touch, but the image is: 1. Check whether the wrong file touchpanel (needed for your model โ€“ begonia or begoniain). 2. Try to roll back to the stock MIUI via Fastboot. 3. If it does not help โ€“ reflash only the vendor section from the original firmware.

4. Which firmware to choose: comparison of MIUI, AOSP and ported assemblies

The choice of firmware depends on your goals, and below is a comparison of the most popular options for the Redmi Note 8 Pro:

Type of firmwarePlusesConsFor whom?
Official MIUI (Global/EEA)โž• Stable operation of the camera and network โž• Support for Widevine L1 (HD Netflix) โž• Official updates (albeit rare)โž– Advertising and bloatware โž– No new versions of Android โž– Slowdown over timeFor those who value stability
LineageOS 20 (Android 13)โž• Clean Android without unnecessary apps โž• Regular security updates โž• MicroG support (alternative to Google Services)โž– No GCam "out of the boxยป โž– Possible bugs with Bluetooth โž– A complex installation for beginnersFor enthusiasts and lovers of privacy
Pixel Experience (Android 12)โž• The interface is like Google Pixel โž• Built-in GCam with night mode โž• Optimized productivityโž– No VoLTE on some operators โž– The battery is worse than the battery. MIUI โž– No official support (assemblies from the community)For those who want a pixelated experience
Port with Redmi K30 Proโž• New features from the flagship โž• Perhaps the best optimization for gamingโž– High risk of brick โž– Sensors do not work (gyroscope, compass) โž– No guarantee of stabilityOnly for experienced users

If your goal is to simply get rid of advertising and speed up your smartphone, just install MIUI without bloatware via TWRP (for example, the MIUI by StagOS build). LineageOS or Pixel Experience is suitable for maximum performance and a new Android.

  4. Connect your phone in Fastboot mode (clip Power + Volume down) and follow the program instructions.

Note: Xiaomi may refuse to unlock if the account is new (less than 7 days) or linked to another device.

Step 2: Installation of TWRP Recovery

For the Redmi Note 8 Pro, OrangeFox Recovery or TWRP by Mauronofrio is suitable. Download the.img file and run through Fastboot:

fastboot flash recovery orangefox-recovery.img


fastboot reboot recovery

Step 3. Firmware through TWRP

  1. Copy the firmware file (.zip) to your phone.
  2. In TWRP, select Wipe โ†’ Advanced Wipe and select Dalvik, Cache, System, Data.
  3. Press Install, select the firmware file and confirm.
  4. After installation, run Wipe Cache/Dalvik and restart.

โš ๏ธ Note: If you are a custom firmware (not a custom firmware) MIUI), First install vendor and firmware from the stock version, otherwise the camera and network will not work.

๐Ÿ’ก

If your phone is stuck on the MI logo after you've run it, try TWRP and re-install it. If it doesn't work, run the stock MIUI through Fastboot using the Mi Flash Tool (select the clean all option).

6. Frequent errors and how to fix them

Even with the right firmware, there can be problems, and here are the most common solutions.

Problem.Reason.Decision
Not activated (black screen)Incorrect preloader or interrupted firmwareSwipe stock MIUI through SP Flash Tool with Download Only tick
No network (IMEI invalid)The nvram or modem partition is damagedRestore nvram via Maui META or flash modem from stock firmware
The camera's not working.No Mediatek drivers or incompatible GCamInstall ANX Camera or patch for libcameraservice
Fast battery dischargeUnoptimized kernel or background processesSwipe a custom core (Perseus or StormBreaker) or calibrate the battery via Battery Calibration
Google Pay is not working.No SafetyNet certificationInstall Magisk + Universal SafetyNet Fix

If neither method worked, check out the 4PDA or XDA Developers forums, which have separate themes with solutions for the Redmi Note 8 Pro (begonia).

Can I flash Redmi Note 8 Pro without unlocking the bootloader?
No. Without an unlocked bootloader, you can only update via OTA or Fastboot (but only on official MIUI versions).
Which firmware is better for games: stock MIUI or custom?
For games, stock MIUI with backgrounds turned off (via ADB or Greenify) may be better. Castom firmware can increase in benchmarks, but real-world games (Genshin Impact, Call of Duty Mobile) often experience FPS drawdowns due to unoptimized Mali-G76 drivers.
How to return the stock firmware if something went wrong?
Download the official MIUI for your model from Xiaomi, then: Sweat through Mi Flash Tool (select clean all). or through TWRP (if installed) - just select the.zip file and wipe. If the phone doesn't turn on, use the SP Flash Tool with the scatter file from the firmware.
Why doesnโ€™t NFC work after the firmware?
This is a typical problem when installing Global ROM on a Chinese model (begonia instead of begoniain). Solutions: Switch the correct version of MIUI (for example, MIUI EEA for European devices); Install a patch for NFC through Magisk (for 4PDA).
Should I use Android 13 if I have MIUI 12.5?
If you are satisfied with the current firmware, there is no point in risking. Android 13 on custom firmware for the Redmi Note 8 Pro often works unstable: they can glitch Bluetooth, GPS or autobrightness. It is better to wait for a stable build from proven developers (for example, LineageOS marked OFFICIAL).
