Hi-
Got a J-Link to replace I-jet and tried again to unsecure the locked K20d50m. Here are what I got, still failed to unlock it:

![]()
Also I tried J-Link command line "unlock kinetis" and erase_all_pin.jlk commander script with reset held low, none of them works for me.
Any other solutions I can try here to unsecure the locked one?
Thanks!
