Root the Blackview BV4900
The Blackview BV4900 is a 2020 Android device from Blackview. It runs the Mediatek MT6761V/WE Helio A22 (12 nm), a MediaTek platform, flashed via SP Flash Tool on many models with BROM as the deep-recovery path. Shipped software: Android 10. 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

Typical time
1–3 hours
Method
Magisk via patched boot image (fastboot)
Bootloader unlock on Blackview
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 Blackview BV4900?
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 Blackview procedure.
Does the Blackview BV4900 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 Blackview BV4900 void my warranty?
Blackview will generally treat a rooted Blackview BV4900 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 Blackview BV4900 run?
It runs Android 10. The specifications table on this page lists the full software details.
