The Lenovo K9 is an Android device from Lenovo, released in 2018. It combines the Mediatek MT6762 Helio P22 (12 nm) and a 5.7-inch display, running Android 8.1 (Oreo). This page tracks its full specifications, root status, and the bootloader and recovery notes that apply to it.
Root the Lenovo K9
The Lenovo K9 is a 2018 Android device from Lenovo. It runs the Mediatek MT6762 Helio P22 (12 nm), a MediaTek platform, flashed via SP Flash Tool on many models with BROM as the deep-recovery path. Shipped software: Android 8.1 (Oreo). 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.

Method
Magisk via patched boot image (fastboot)
Bootloader unlock on Lenovo
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 Lenovo K9?
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 Lenovo procedure.
Does the Lenovo K9 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 Lenovo K9 void my warranty?
Lenovo will generally treat a rooted Lenovo K9 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 Lenovo K9 run?
It runs Android 8.1 (Oreo). The specifications table on this page lists the full software details.
