It's not due to any hardware "break". They have temporarily stopped the updating process because of various pesty bugs that significantly increased the users visiting/calling their service center. Here's the official announcement. It basically says the kitkat update has been temporarily suspended to make it more stable but will resume in early April.
Finally, the kitkat release has resumed. Updated kitkat for F240 S/L/K.
I hope international version will update soon..
