FAQs

Q1: How to re-lock the Bootloader?

If you have flashed custom system image, don’t lock the Bootloader, otherwise the device will not boot up.
If you have not used custom image, use the following commands from fast boot mode.
– Enter the command: fast boot flashing lock
– Press “Enter” on your keyboard

Q2: Are there any risks after unlocking the Bootloader?

Please be aware that Micromax can’t guarantee full functionality and will not be responsible, for any third-party unsigned custom ROM being flashed onto your device after the Bootloader is unlocked. An unsigned third-party custom ROM may not have gone through the thorough tests that we run for each device and software version that we release.
A third-party custom ROM may not work properly on your device, certain functions and services may cease to work. The performance and device data may also be affected and may damage the device permanently. In the worst case scenario, unlocking the Bootloader will cause physical injuries or material damage through explosion due to overheating of the device.

Q3: Will it affect future OTAs after unlocking?

Unlocking the Bootloader may cause for the secure user data partition to become inaccessible. Yet if you simply unlock the Bootloader (without flashing custom recoveries or rooting) you will still receive official software updates (OTAs).
But we cannot guarantee that you will still receive updates if you do operations other than simple unlocking the Bootloader (such as flashing custom recoveries, rooting, etc).
Once you re-lock the Bootloader and use the official recovery, you will receive official OTAs again.

Q4: Will it affect warranty?

Q5: How to re-flash the official ROM after installing a custom ROM?

Users need to go to the nearest service centre to flash the device.
