In this article I bring you a mini tutorial on how to unlock the ktag automotive programming interface that was blocked by an unsuccessful update after an internet connection.
Usually the symptoms are as follows:
- Ksuite screen with grayed-out protocols – you can’t click anything,
- When trying to verify information about the interface it does not display the serial number.
To recover the functionality of your interface you must download a set of unlock files for your ktag and also an alternative version of ksuite thus making it possible to unlock the interface.

The file set contains files for the Ktag SD card, a backup of the ft232 chip that exists inside the ktag card, and also the nxp processor rom with reset that must be written with the JLink interface that can be found on aliexpress.
In the vast majority of cases to unlock / unlock the ktag just copy the set of files that are available in the external link provided above, to the Memory Card SD card of the ktag and insert the card back into the ktag, uninstall the ksuite from the pc and install the recommended version.
Your SD card should be formatted before anything, be sure to seal to fat32 format.
And you’ll be unlocking the interface again. But there can always be cases where you will need to write NXP firmware again using JLink, remembering that this procedure also resets tokens, from old interfaces that had limited number of tokens.
