Earlier this week we reported on a new firmware build 14.2.A.1.144 certified by the PTCRB website for the Xperia Z1 (C6903 only) and Xperia Z1 Compact (D5503). The build was only certified on the European/Asian LTE model of the Xperia Z1 suggesting that it could be a carrier update.
Well now the same firmware build has been certified for the Xperia Z Ultra (C6833 model only). The firmware looks like a minor one over the last certified firmware (14.2.A.1.142), so we only expect minor bug fixes.
Thanks difwwh!
