Can't update XZU C6802 to 4.3, device modified? SOLVED - unlocked bootloader.

[speculatrix]

I held off updating my XZU to 4.3 until root was found, as I don't want to live without it (because of: Titanium backup, VPN software, full linux install on uSD card).

My XZU has an unlocked bootloader, too, as well as being rooted. I'd also modified /system/build.props too.

When I saw the OTA, I tried it and it failed without giving a reason, so I booted up Windows and used Sony PC Companion, and it too failed:

I've looked at many XZU update threads and none seem to mention this specific issue.

When the tool runs, it takes a minute to "prepare" (it seems to have kept stuff it downloaded the first time). The phone does stuff, screen goes blank. Then the update fails giving the above message. The phone is then dead, and I have to unplug the USB before I can turn it on.

I restored the standard build.props from a backup copy. Do I need to relock the bootloader? Remove SuperSU and unroot?

Laptop computer has lots of free disk space, and is running standard win7pro-x64, nothing special installed.

thanks for any ideas.

I think that it is the unlocked bootloader?

I just flashed the ce 290 ftf when I had some error in pcc. Might have been the same one.

Rooting is easy on 290 if you have an unlocked bootloader

it's not root, because I unrooted device, so I am guessing its the unlocked bootloader. I've never managed to get Barclays Bank mobile app to work as it complains about phone being rooted, still doesn't work, so it must be detecting the system modified flag (this is using the older version of the app which was happy to run on a fully p0wned Galaxy Note 2).

OK, it was the unlocked bootloader. OTA update now working.

thanks!
