I'm currently on stock. 757 firmware and before two days I had a notification about updating to the latest 14.4.108 firmware. Problem is that no matter if I download it through WiFi or 3g, It kept showing that "cannot verify update ", and nothing happens. Anyone else has this? Any ideas or suggestions much appreciated...

Root is not the problem. Mine is not rooted but still the problem insists. Even pc companion couldn't update the device. WTF?

Plus, I even factory reseted but nothing changed...

I had the same problem with OTA.
PcCompanion did update but my Z1c crashed now often.
So I flashed the ftf with flashtool and this time it worked perfect.

I came from .757, rooted and locked bootloader.

Now rooted again with Easy Root Tool v8 :)

Well I try PC companion app on other computer and it did update without problems.
I can see the difference in OS (Windows 7 vs. Windows 8) and installed ADB drivers on not working computer.
