Infinix Note 40 Overview
The Infinix Note 40 is an Android device from Infinix, released in 2024. It combines the Mediatek Helio G99 Ultimate and a 6.78-inch display, running Android 14. This page tracks its full specifications, root status, and the bootloader and recovery notes that apply to it.
Root the Infinix Note 40
The Infinix Note 40 is a 2024 Android device from Infinix. It runs the Mediatek Helio G99 Ultimate, a MediaTek platform, flashed via SP Flash Tool on many models with BROM as the deep-recovery path. Shipped software: Android 14, XOS 14. For this model the realistic path is: a standard fastboot bootloader unlock, followed by Magisk via patched init_boot image (fastboot). Typical hands-on time is 1–3 hours.
Difficulty
Moderate — brand-specific steps involved
Typical time
1–3 hours
Method
Magisk via patched init_boot image (fastboot) — KernelSU also viable (GKI kernel)
Bootloader unlock on Infinix
Unlock procedure follows the generic Android flow: enable OEM Unlocking in Developer Options, then unlock via fastboot. Exact availability depends on the model and region — confirm before flashing.
Platform notes
MediaTek platforms flash through SP Flash Tool rather than plain fastboot on many models, and expose BROM mode as a deep-recovery path. Correct scatter/firmware matching matters more here than on Snapdragon devices.
Before you start
- Bootloader unlocking factory-resets the device on almost all models — back up everything first.
- As a device launched on Android 14, the Magisk target is typically init_boot.img, not boot.img — patching the wrong image is the top bootloop cause on newer models.
FAQ
Can I root the Infinix Note 40?
Yes. After enabling OEM Unlocking and unlocking the bootloader, root is Magisk via patched init_boot image (fastboot). The unlock notes on this page describe the exact Infinix procedure.
Does the Infinix Note 40 support custom recovery (TWRP)?
That depends on community support for this exact model — verify a build exists for its codename before flashing anything. TWRP is not required for root: Magisk installs by flashing a patched init_boot image via fastboot.
Will root the Infinix Note 40 void my warranty?
Infinix will generally treat a rooted Infinix Note 40 as outside warranty while it is modified. Restoring full stock firmware before a service visit usually restores normal treatment in practice, and consumer law in some regions (such as the EU) may still cover defects unrelated to root.
What Android version does the Infinix Note 40 run?
It runs Android 14, XOS 14. The specifications table on this page lists the full software details.
