Compressed firmware package of 2.87 MB labelled CKU_MT50IN1 version 02 with an onboard tag, apparently for an MT50-series board with onboard components, though the brand and device are not named. The exact meaning of the CKU prefix cannot be confirmed from the name. Extract the archive and examine the image size and any notes inside before use. As with any SPI dump, read and keep the existing chip contents first, confirm capacity matches, and verify the board marking agrees with the image.
