Bootloader unlock on Lava

- Bootloader unlocking factory-resets the device on almost all models — back up everything first.
FAQ
Can I root the Lava Z40?
Only if this exact model and region are eligible for a bootloader unlock. 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. Once an unlock is approved, root is Magisk via patched boot image (fastboot).
Does the Lava Z40 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 Lava Z40 void my warranty?
Lava will generally treat a rooted Lava Z40 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.
