This Micromax Q402+ firmware (stock ROM) will help you easily un-brick and restore your device to its default factory state. If you have previously rooted or modified the system (or other) partition of the phone in any way, flashing this stock ROM will overwrite all existing modified system files to replace with factory software.
If you have important data on the phone (like contacts, messages, app data, etc), please back them up because you could loose data after flashing.
Charge the phone to at least 50% so that the flashing process will not be interrupted by low battery. Interrupting the firmware installation means bricking your phone.
Download the firmware file from the link below and follow the recommended flashing instructions immediately after the download options. Please report any broken links discovered.
