TCL 408 Overview
The TCL 408 is an Android device from Tcl, released in 2023. It combines the Mediatek MT6762G Helio G25 (12 nm) and a 6.6-inch display, running Android 12. This page tracks its full specifications, root status, and the bootloader and recovery notes that apply to it.
Root the TCL 408
The TCL 408 is a 2023 Android device from Tcl. It runs the Mediatek MT6762G Helio G25 (12 nm), a MediaTek platform, flashed via SP Flash Tool on many models with BROM as the deep-recovery path. Shipped software: Android 12. For this model the realistic path is: a standard fastboot bootloader unlock, followed by Magisk via patched 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 boot image (fastboot) — KernelSU also viable (GKI kernel)
Bootloader unlock on Tcl
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.
FAQ
Can I root the TCL 408?
Yes. After enabling OEM Unlocking and unlocking the bootloader, root is Magisk via patched boot image (fastboot). The unlock notes on this page describe the exact Tcl procedure.
Does the TCL 408 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 boot image via fastboot.
Will root the TCL 408 void my warranty?
Tcl will generally treat a rooted TCL 408 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 TCL 408 run?
It runs Android 12. The specifications table on this page lists the full software details.
