Coolpad Cool 40i Overview

The Coolpad Cool 40i is an Android device from Coolpad, released in 2024. It combines the Mediatek MT6765 Helio G37 (12 nm) and a 6.56-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 Coolpad Cool 40i

The Coolpad Cool 40i is a 2024 Android device from Coolpad. It runs the Mediatek MT6765 Helio G37 (12 nm), a MediaTek platform, flashed via SP Flash Tool on many models with BROM as the deep-recovery path. Shipped software: Android 14, CoolOS. 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 Coolpad

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 Coolpad Cool 40i?

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 Coolpad procedure.

Does the Coolpad Cool 40i 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 Coolpad Cool 40i void my warranty?

Coolpad will generally treat a rooted Coolpad Cool 40i 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 Coolpad Cool 40i run?

It runs Android 14, CoolOS. The specifications table on this page lists the full software details.
