We Lenovo K900 users and developers demand more support from lenovo to enjoy the most of our device. Being a flagship device from 2013, lenovo only provided 4.2.1 for international users, 4.2.2 for Chinese users and a 4.3 in beta stage without updates since may. That been said, Motorola RAZR I recently got official news about it's update to kitkat(being an older phone with older Intel CPU) also Samsung galaxy tab 3 10.1 and dell venue 8 both with Intel CPU have been updated to kitkat On second hand as a developer I would like lenovo to provide us a dev firmware which let us flash unsigned recovery and kernel images to let us improve the performance of the device. I hope lenovo take in consideration this petition. Their costumers of a flagship device deserve more attention from the company. Thanks.
