Stock 4.4.3 zips: http://goo.im/devs/Tassadar/stock_zi...4l_grouper.zip or http://devhost.xda-developers.com/nXC
4.4.3 kernel sources were not released yet.
@Tasssadar, i tried to create a zip myself using ArchiKitchen, but when i tried to flash as a second ROM it gives me error. Not sure what needs to be done. Tried for help in the Kithen's thread but JustArchi was not sure how the device works and suggested to check in the device threads. If anyone could look at the recovery log and help me with fixing the errors it would be of great relief. Been trying it since a long time.
