Rooted and updating to 4.3

Hey guys I have a rooted Xperia Sp(C5302). We know that our device is gonna get the 4.3 official update next month. My question is can we update to the official 4.3 even after having root or will it cause a problem.

If its rooted; you can update via pc companion. (i don't know if OTA; but via pc companion you can). Cheers!

As said above, root is no problem with PC Companion.
However, if you unlock the bootloader, no update whatsoever (PC Comp, OTA). After bootloader unlock only Flashtool /Emma will let you flash new ROM/updates.

Hi , so if i Relock the boot loader i will be able to use ota rite?
which is the safest method to Reload the Boot loader
I am using BL Unlocked Rooted Stock Rom ,

I think Sony stated on their unlock website that once you unlock the boot loader there's no way to relock. Check out unlockbootloader.sonymobile.com

If you backed up your DRM keys with TA-backup you should be able to relock if you didn't you are kinda screwed

[Q] Unlocked Bootloader, Unrooted OTA Update?

Heyy guys I have a XperiaSP which have unlocked bootloader and unrooted phone (just unrooted it a while ago). I would REALLY like to update my phone because there's too many bug here on Xperia SP. However, when the phone was still rooted I tried to update and it failed. Now after unroot I was going to update but then the fact that I unlocked the bootloader I am really worried about wiping/bricking the phone through OTA update. Any help pls?
P.S - My phone is barely Unlocked. It is nearly as stock and no custom recovery nor root is installed.:laugh:
Edit : By the way, is the Xperia SP really got Wi-Fi issues? My iPod got full signal on home's wifi and my SP got barely 1-2..

hmmm

did u try using PC companion? Is It ok there?
Or else I think you know that Sony's 4.3 update is on the corner. that may will solve your issue

Ahh yeah gonna try that ASAP. but I just forgot to mention that my primary laptop is now on service center (Got a bit problem there) so I can't really update my SP through that.
I tried updating just now through OTA. After the reboot a popup message appeared :
"Could not install new software version. Try again."
Is that because of my unlocked bootloader? Cos I unrooted my phone completely through SuperSU.
If so how to relock the bootloader??

If you want to relock the bootloader just use FlashTool. In your case because you don't have any custom Firmware on your phone this should be quite easy.
But I always thought when updating with having root access you can update but lose root. Maybe it didn't work (the update) because of a complete diffenent reason. Did you try it a second time?

When I got my laptop back, I'm definitely going to relock the bootloader. But if I do something wrong, will it hard brick or something? (sorry for my parranoidness) and relocking is not much difference from unlocking right?
I tried installing the software update the second time. Unlocked BL, fully unrooted (No Super SU). Still fails gonna try at PCCompanion

You should flash stock ROM using flashtool, relock the bootloader, and then restore the TA partition

I'm on my stock ROM now (Default Sony ROM right? But I've updated it before, does it count as stock?)
What's TA partition?
Sorry for noob Qs

I never do this before.So can I update my phone via pc companion via unlocked bootloader?On stock rom without root and recovery?

If you didn't flash anything on your device you can relock your bootloader without any problems. If you had a custom recovery, kernel or ROM and you relock your bootloader while having this custom recovery, kernel or ROM this should brick your phone (I think this could even be a hard brick) but if everything is stock (like I already said) there shouldn't be any problems with relocking
TA partition contains the working bravia engine (2) which gets lost if you unlock bootloader. If you had made a backup of the TA partition you could restore this and get the bravia engine back

if i didnt make backup (because no one told me to ) i cant install 4.3 update from Sony if comes out ?

Yes, you'll be able to get the 4.3 update without the TA partition. But, as everyone else here said, make sure you're on a stock ROM, with a locked bootloader.

Locked bootloader ----> You can use PC Companion or Flashtool to update your phone
Unlocked bootloader ------> Flashtool only
Also, don't try to update your phone via OTA while having your bootlader unlocked, because it will brick your device.

My original Stock Rom had been flashed to CM 10, but now I have flashed it back to stock rom that I tried to search online from this site. Is it counted as original stock rom or not? My phone is unlocked bootloader, and I got ota update but cannot install, I don't know why; maybe it has been changed or maybe of unlock bootloader?

I'm afraid that Sony has replaced PC Companion with the new Xperia companion that maybe does not have backward compatibility with old phones like our Xperia SP. and that's the reason why you and many other people are getting this error.
I was able to repair my phone many times before using PCC following these steps shown in this link below:
https://talk.sonymobile.com/t5/FAQ/How-to-perform-a-software-repair-with-PC-Companion/m-p/1061294
As I said before you are not the only one getting this error and there's no solution proposed yet from Sony:
https://talk.sonymobile.com/t5/PC-Mac-Software/Can-t-repair/td-p/1116387
But for now, just make sure that you've uninstalled all flashing programs and removed old drivers before installing Xperia companion. and also make sure that there's no other devices connected or software emulator for Android installed before trying to repair the phone.
Sorry dear, I wish I could be of more help.
