The Oppo A3x (China) is an Android device from OPPO, released in 2024. It combines the Mediatek Dimensity 6300 (6 nm) and a 6.67-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 Oppo A3x (China)
The Oppo A3x (China) is a 2024 Android device from OPPO. It runs the Mediatek Dimensity 6300 (6 nm), a MediaTek platform, flashed via SP Flash Tool on many models with BROM as the deep-recovery path. Shipped software: Android 14, ColorOS 14. For this model the realistic path is: the brand-specific unlock described below, followed by Magisk via patched init_boot image (fastboot). Typical hands-on time is 2–4 hours (after eligibility check).
Difficulty
Advanced — verify unlock eligibility first
Typical time
2–4 hours (after eligibility check)
Method
Magisk via patched init_boot image (fastboot) — KernelSU also viable (GKI kernel)
Bootloader unlock on OPPO
OPPO gates unlocking behind a "deep testing" application that is approved only for select models and regions — availability must be confirmed per device before any commitment.
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 Oppo A3x (China)?
Only if this exact model and region are eligible for a bootloader unlock. OPPO gates unlocking behind a "deep testing" application that is approved only for select models and regions — availability must be confirmed per device before any commitment. Once an unlock is approved, root is Magisk via patched init_boot image (fastboot).
Does the Oppo A3x (China) 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 Oppo A3x (China) void my warranty?
OPPO will generally treat a rooted Oppo A3x (China) 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 Oppo A3x (China) run?
It runs Android 14, ColorOS 14. The specifications table on this page lists the full software details.
