Simple, no
Don't accept any OTA firmware if you unlocked bootloader
You can update firmware via flashtool by downloading stock FTF firmware

Very good advice. Don't do OTA
If there is no ftf posted you can make one
Use PCCompanion and use the "repair" option. It will download the necessary files to flash your phone but will fail to flash because if your unlocked bootloader.
Then use flashtool to make the ftf from the downloaded files which ou can then flash in flashtool
the instructions on how to do this are in the all in one thread

[Q] How to root stock .257 firmware if bootloader is locked?

Hello, sadly I have rooted the Z1 within .534 without unlocking the bootloader and didn't realize that update via PC Companion overwrite the root access. I updated to .257 with PC Companion and then I have a Z1 updated, unrooted and without being able to be downgraded to .534 as I have read in other threads.
Can anyone help me to root the device in this condition? Suggestions?
Thanks

You follow the either one of the 3 or 4 guides that are in the general section.
PS, you can always downgrade no matter of whether you are rooted or not.

just install Flashtool v0.9.13 on PC, download the FTF .136 file, turn off your phone, hold volume down all the time and connect via USB to PC, let windows install the drivers for Flashmode, put the FTF in Flashtool folder, open Flashtool, click flash, select the FTF, do Wipe Data, appslog, cashe, hold volume down all the time, flash it, when you see the first percent of the progerss on green bar you can leave the volume down, enjoy 4.3 FW .136.

Thank you for your reply. I know how to flash FW with flashtool, but where can i download .136 FW for my device (C6943) ?
And i will probably lose root, right? Can it be rooted?

[Q] How to go back to Stock official ROM sony xperia z1

I'm on ihackers 2.1 ROM android 4.3
rooted
unlocked bootloader
I wanted to go back to stock to C6902_14.2.A.0.290
I found the method but I'm not sure if this is the right way http://lionking853.blogspot.co.uk/2013/11/how-to-go-back-to-stock-firmware-on.html
and if it is the right way, after going back to stock ROM, will my phone unroot and relock again?
Can I just go ahead and do this or must I relock bootloader first?
please help me since I never done this before, only rooted and unlock that I did.
Thank you so much folks

Thank you, I'll do that

done
I'm finally back to stock ROM and it's much faster than custom ROM
I think it is much more stable too.
I'm no longer rooted anymore but bootloader is still unlocked.
I'm happy now

You can install custom kernel & have root

If you have an unlocked bootloader, you will not be able to update using PC Companion. I didnt know all this **** were involved in Sony phones.
I had unlocked my bootloader a couple of days back, didnt know I had to backup my DRM keys and ended up losing my warranty. Now I cant even update my phone using the official updating method.
BTW... the recovery is bundled with the kernel, thats why people refer to it as flashing a kernel instead of recovery. I didnt know this until 2 days back.

Thanks

If I am on a Locked Bootloader and on a rooted custom ROM, will Sony PC Companion detect my phone when the next update comes??

This is stupid. If you are in 4.3 (.290) with un-locked boot loader you cant update via PC companion or SUS.
I ended up going to 534 (4.2) via flashtool. Root it, restore TA backup and then use SUS to update. And flashing the latest 4.3 via Flashtool din work.

No PC Companion or SUS won't detect your phone.. You've to manually flash a valid ftf from Flashtool.. Then you can connect & update your phone through PC Companion or SUS..

[Q] why do I'm unable to upgrade to kit kat?

Hi,
I have a 4.3 installed on my phone, I woul upgrade to 4.4, but I don' know how to do that.
If I check with pc companion, ittell me that there is no upgrade, and the same by OTA.
I'm wondering if is it possible that I'm still out of upgrade.
How can I upgrade it...?
TIA

Is your Z1 a UK unbranded one? Uk unbranded seem to be always the last one to get updates. You could back up your phone then perform a repair. Doing repair may wipe your phone so consider before doing it. BTW you have posted in Q&A section. Please move to Q&A Moderators many thanks

If you can't post in the correct section you are unlikely to know where the search button is either...

If you have root or unlock bootloader on your device you cant upgrade it through SUS or PCC. Lock it back or flash it via flashtool.

This is incorrect.
If you have root you can still update via PCCompanion or SUS, but you will lose root.
If you have an unlocked bootloader then you cannot use official tools such as PCCompanions or SUS, you can only use EMMA (Official tool from Sony for unlocked bootloaders)

You will be able to use PCCompanion once the update becomes available for you, they are not all released at the same time, it can roll out over a month or two.
In the meantime, you can flash a FTF using flashtool from flashtool.net and there is no need for root. It is just a repackage of an official download and made avaialable for all.
Find them in the FTF mega collection thread.... Use the search button.
