Xiaomi Mi 5s Plus (natrium) Firmware Flash File Download [Stock Rom]

The Xiaomi Mi 5s Plus (codename natrium), launched in 2016, was the larger, camera-focused flagship sibling in the Mi 5s series. Designed for users who wanted more screen real estate, it featured an expansive 5.7-inch display and a powerful Qualcomm Snapdragon 821 processor. Its most innovative feature was the dual 13MP camera system, which paired a standard color sensor with a dedicated monochrome (black and white) sensor. This setup allowed the phone to capture incredibly detailed images with excellent contrast and low-light performance. For owners of this classic phablet, this page provides official fastboot ROMs for China and Global, the popular Xiaomi.eu custom ROM, and two versions of the TWRP custom recovery.

Important: You must verify your device is a Mi 5s Plus (natrium). This firmware is not compatible with the standard Mi 5s (capricorn), which has a different screen, camera, and fingerprint scanner. Flashing the wrong firmware will hard brick your phone.

How to Flash Official ROM (Mi Flash Tool)

This is a quick checklist for this device. For a complete tutorial on installing drivers, unlocking the bootloader, and troubleshooting, please read our master guide:

Use this method to unbrick your phone or restore official MIUI firmware.

1. Boot into Fastboot mode (Power + Volume Down).
2. Extract the official firmware (.tgz file) and select the main folder containing the /images directory in Mi Flash Tool.
3. Select clean all for a safe installation (you can use clean all and lock to return to a fully stock, locked state).

How to Install TWRP & Flash Custom ROMs

Use this method to install the Xiaomi.eu custom ROM or other community-developed ROMs.

What is TWRP? TWRP (Team Win Recovery Project) is a powerful custom recovery that replaces your phone’s limited stock recovery. It is the essential tool that allows you to install custom software (.zip files), create full backups of your system (a “Nandroid”), and perform other advanced maintenance. The official ROMs on this page do not require TWRP.

Disclaimer: This is an advanced process. Proceed at your own risk.

1. Unlock the Bootloader: This is a mandatory first step. Use the official Mi Unlock Tool.
2. Flash TWRP:
   • Boot your phone into Fastboot mode (Power + Volume Down) and connect it to your PC.
   • Using ADB & Fastboot tools on your PC, flash your preferred TWRP .img file with the command:
     fastboot flash recovery twrp-filename.img
3. Boot into TWRP: After flashing, immediately boot into recovery by holding Power + Volume Up.
4. Install Custom ROM:
   • In TWRP, it’s recommended to first go to “Wipe” and perform a Factory Reset.
   • Transfer the Xiaomi.eu .zip ROM file to your phone’s storage.
   • In TWRP, tap “Install,” select the .zip file, and swipe to confirm the flash.

Device-Specific Troubleshooting for Mi 5s Plus (natrium)

The Mi 5s Plus has some unique hardware that requires special attention.

• Hard Brick Recovery (EDL Mode): If your phone becomes completely unresponsive (hard bricked) after a failed flash, the primary recovery method is EDL Mode (Qualcomm 9008). This requires opening the phone and shorting two specific test points on the motherboard while connecting it to a PC, which forces Mi Flash Tool to detect it for a low-level flash.
• Dual Camera on Custom ROMs: The unique RGB + Monochrome dual camera system may not be fully supported on all custom ROMs, especially AOSP-based ones (like LineageOS). The secondary monochrome sensor often fails to work. For full, reliable camera functionality, it is best to use official MIUI or a MIUI-based custom ROM like Xiaomi.eu.
• Model Confusion Brick: Ensure you have the Mi 5s Plus (natrium). Flashing firmware for the smaller, single-camera Mi 5s (capricorn) will cause a hard brick due to significant hardware differences.
• NFC Not Working: If your NFC is unresponsive, the first step is to toggle it off and on in settings. If the issue persists, a clean flash of the latest official fastboot ROM for your region can often resolve software-related NFC driver problems.

FAQs

Q1. What’s the main difference between the Mi 5s Plus (natrium) and the standard Mi 5s (capricorn)? The Mi 5s Plus (natrium) is a larger phone with a 5.7-inch screen and a dual-camera system. The standard Mi 5s (capricorn) is smaller with a 5.15-inch screen, a single (but excellent) camera, and an under-glass ultrasonic fingerprint scanner (the Plus has a traditional rear scanner).

Q2. How did the dual-camera system work? The system used two 13MP sensors. One captured standard color (RGB) information, while the other was a dedicated monochrome sensor that captured only black and white information. The phone would combine the data from both, using the monochrome sensor’s image to add significantly more detail and light information to the final color photo.

Q3. What was the final official update for the Mi 5s Plus? The Mi 5s Plus launched with Android 6.0 Marshmallow and received its final major OS upgrade to Android 8.0 Oreo. The MIUI 11 build provided here is the last official software update for this model.

Q4. Why are there two TWRP links? Which one should I use? The table lists both the Official TWRP from the main project website (twrp.me) and a popular third-party build. For most users, the Official build is the recommended starting point due to its proven stability. Different builds sometimes offer compatibility with specific ROMs or Android versions, which is why alternatives exist.
