getting official update when rooted?

hi!
my xperia z bootloader is locked and can be unlocked, i'm still on stock rom 4.1.2.
i'm planning to get root and install a recovery, but keep the bootloader locked. will it then be possible to receive sony's offical jb 4.2.2 update when rooted and recovery installed? i know that once the update 4.2.2. is installed i will have to re-root.
thanks

Yes you will get notification of new official updates if you are rooted

Thanks for your reply.
But will it install? Just a notification would be useless...
Or will I have to get the update somewhere here on xda and flash it manually?

It installs, and overwrites your root. For now that's not an issue, but when 5.0 comes out it might not be possible to get root again due to SELinux being implemented.

Yes exactly as Tom mentioned, it will happy install from PC Companion straight over top, then you just need to re-root again.
4.2.2 would be nice first Tom

[Q] Relock bootloader for update?

Hi there, i've got an xperia z with official firmware, kernel and recovery.
It's running on 4.1.2 now but it downloaded an update which is 4.2.2 I guess. When I try to install it it fails, is this because my bootloader is unlocked?
Do I have to relock it using Flashtool?(without ftf file)
Does relocking it erases data? (like when you unlock it)
Can I safely use the ota?
Thanks in advance broski's

[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

I downloaded stock C6902_14.2.A.0.290 which is 4.3 it's the tft file
can I just flash it using flashtool? I want to wipe everything, no need to back up, I mean I want it to feel like a brand new phone. like factory reset.u know, and It doesn't matter about root or bootloader,

if you don't want to relock your bootloader then just go back to .290 with flashtool

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 you do have a TA backup then you don't have to do anything else then restoring it on a stock rooted firmware..If you don't then use flashtool to relock it..
Revert back for more help..

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] Official Update 4.3 with ck/ub/root/cwm-twrp dual-boot

Hello community,
this is my first post here so i hope, i do it right
Please excuse my english, it is not perfect.
I have a xperia z with Android 4.2.2 (10.3.A.0.423) . The bootloader is unlocked, cwm/twrp dualboot is installed, also the doomlord customkernel v19 is in use, root-access is available.
Is it possible to update to official stock firmware 4.3 (10.4.1.B.0.101) using the PC-Companion without bricking my phone? Root-Access and cwm and so on would be lost as i assume. This would be ok for me.
I really would like to do it that way. I think, as an alternative, i could flash the 4.3 stock rom using cwm? Going this way, will my data and all settings be lost?
Updating via OTA is not a good idea i think.
Thanks for advise
Greetings

Well, you cannot update via PC companion, Sony Update Service or OTA, as your bootloader is unlocked.
So, that leaves updating via Flashtool or flashing a prerooted rom from the development section.
The cleanest way would be via Flashtool, then simply flash a custom kernel again and root.

And if im going to flash the stock-kernel which belongs my current firmware and then relock the bootloader?
If the bootloader is relocked, i can't flash a kernel or something else anymore right?
EDIT: If I decide to flash a rom will my data be lost or is it like im doing an normal update?
Is it possible to go back to stock with everything?
So much questions Sorry, I don't know that much, please help

Can anyone help?

Yes, if you relock the bootloader, you should be able to update via the normal methods (at least via PC companion, unsure about OTA). A locked bootloader means you cannot use custom kernels.
If you flash with Flashtool, you can choose not to wipe your data.

I assume, it would be the best to flash the original kernel before i lock the bootloader?
After relocking the bootloader and installing the update via PC-Companion, will the kernel be the "original" kernel and will cwm/twrp be still there or not?

Yes, flash a stock kernel before locking the bootloader. If you don't, you will soft brick your phone.
After updating, you will have a stock kernel and your custom recovery will be gone as well as root.

So everything worked fine. I relocked the bootloader via flashtool and installed the firmware using PC-Companion. My Xperia Z is now totally "stocked"
Thank you very much for your help

You're welcome. Glad to help.

[Q] Unable to upgrade from 4.2.2

Long story short, sent my phone away for warranty repair and it came back with 4.2.2 flashed on it. Never rooted it or modded it in any way. I wanted to update it back to 4.3 and from there eventually back to 5.1, however, the phone says that it's up to date - same thing with PC Companion. Tried to repair it via PCC and I also did a factory reset on it, both to no avail.
Is there any way to force the OTA update(unless I have to wait for X days) or is rooting and flashing the only way out of this? C6093, build 14.1.G.1.534, cust. no. 1276-1193.
Thanks in advance.

I am on mobile at the moment and hope
my search went correct. then you are on a branded swedish firmware from tele2.
Where are you from and what firmware was on your phone before you gave it to repair?
You can flash any firmware you want with the help of flash tool app.

Thanks for the flashtool tip, I unlocked the bootloader and used Sony's Emma flashtool to flash it back to 5.1.1.
Thanks again!

You didn't have to unlock your bootloader to flash a firmware to your phone!
Did you backup your ta partition because unlocking your bootloader means you will loose your DRM keys?
