Recently 14.2.A.1.142 firmware was certified for Xperia Z1 C6903, Xperia Z Ultra and Xperia Z1 Compact on PTCRB from which 14.2.A.1.142 firmware rolled first on Xperia Z1 Compact ( carrier devices ) and then 14.2.A.1.146 firmware was spotted on Chinese Xperia Z1 Compact M51w which is yet not available for sale. Now 14.2.A.1.142 firmware is seen rolling on some carrier specific Xperia Z1 also. 14.2.A.1.144 firmware has already been certified for Xperia Z1, Xperia Z1 Compact and Xperia Z Ultra.

14.2.A.1.142 firmware ( Android 4.3 ) is confirmed on Xperia Z1 Deutsche Telekom carrier handset in Germany which is a minor bug fixing update only and was spotted for Xperia Z1 C6903. Some users are still experiencing touch screen unresponsive and sound enhancement force close issue still on this update.

We don’t expect this Xperia Z1 14.2.A.1.142 firmware to roll out globally on regular variants.

As 14.2.A.1.142 firmware is a carrier specific update so it is full of bloatwares from the carrier. Avoid flashing on regular Xperia Z1 variants.
