This guide will explain how to hide or remove Yellow, Red and Orange state warnings on a Mediatek Android device. Its ideal for those who feel irritated by constantly seeing these warnings on reboot.

Spoiler Alert!
For Red State, you'll need to flash a factory signed firmware

Note
For models with Verified Boot (dmverity), ensure to disable dmverity first

What are Yellow, Red and Orange state warnings?

They are verified boot states. You'll get these on some devices after either unlocking the Bootloader or flashing a modified / non-factory-signed file to the device (usually on a locked bootloader). Red State is often synonymous with a brick.

• Green state means the device is locked or verified, the keystore is verified with an OEM key, and that the boot image was verified by the keystore
  
• Yellow state means that an alternate keystore was used to verify the boot image
  
• Orange state indicates that the device is unlocked, so no verification was done.
  
• Red state means that a device in the locked or verified state had a boot image that did not verify.
  

The warnings look something like:

Red State
Your device has failed verification and may not.....work properly...Please download %s image with correct signature.....or disable verified boot....Your device will reboot in 5 seconds

Orange State
Your device has been unlocked and can't be trusted..Your device will boot in 5 seconds

Requirements

• LK.bin or .img either from your device's firmware or backed up / dumped from the device
  
• Hex Editor (HXD @ https://mh-nexus.de/en/hxd/ is used in this guide)

Do we need to convert lk.back file to .img for flashing if something goes wrong or we can also flash that one which is present in firmware.
