As predicted by us that a 14.2.A.0.2XX firmware will land as android 4.3 on both Xperia Z1 and Xperia Z Ultra and more specifically we mentioned “14.2.A.0.290” firmware and here it comes. Finally PTCRB has certified android 4.3 14.2.A.0.290 firmware for both Xperia Z1 and Z Ultra on their site and most importantly the same firmware build is certified for both phones like previously Sony rolled out same firmware build on Xperia Z, ZL, ZR and Tablet Z.

[ UPDATE – 16 December ]
