Disclaimer

• While this is a collection of unmodified images, you still need to have the bootloader unlocked.

• You can re-lock the bootloader after flashing images.

• SHA-1 hash of <name>-FullOTA.zip file has been provided. It is to be noted that the built-in NothingOS Offline Updater Tool autonomously verifies file integrity. It initiates the update process only if the file aligns with the hash values specified in payload-properties.txt, which is obtained during the creation of the update package.
