Root the Energizer Ultimate U620S
The Energizer Ultimate U620S is a 2019 Android device from Energizer. It runs the Mediatek MT6765 Helio P35 (12 nm), a MediaTek platform, flashed via SP Flash Tool on many models with BROM as the deep-recovery path. Shipped software: Android 9.0 (Pie). 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.

Typical time

Bootloader unlock on Energizer
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.
- This device is not confirmed released; root information is provisional until retail firmware exists.
FAQ
Can I root the Energizer Ultimate U620S?
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 Energizer procedure.
Does the Energizer Ultimate U620S 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 Energizer Ultimate U620S void my warranty?
Energizer will generally treat a rooted Energizer Ultimate U620S 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 Energizer Ultimate U620S run?
It runs Android 9.0 (Pie). The specifications table on this page lists the full software details.
