Question about bootloader/root - Xperia SP Q&A, Help & Troubleshooting

I have a question... I try the leaked 4.3 ROM by DooMLoRD, but it works really really really bad for me!
Now i RE-LOCK my bootloader and i flash stock rom. I am wondering if now my phone is still rooted and if i can get the 4.3 update when is released...?

You will have lost root by flashing stock ROM... by going back to stock you will get updates via phone and PCC.

@Jared89 if u have took the backup of TA partition.
And then relocked the BL with the latest flashtool and restore the TA then u will be as good a new.
U can get all the updates.

Okay, but i dont have backup. So i will NOT get the updates ?

I think so but I am not sure.
U can still flash the latest official when released.
So its not a worry.

I noticed that my phone is not working the same way as before unlocking the bootloader. Is slower now.
Anyway... Is there any other way to make my phone like NEW... like i never unlocked the bootloader ?

Just out of interest, when an FTF file becomes available, could you then flash it with flashtool on a stock ICS locked bootloader?
Judging by past firmware updates, it's taken 2/3 months for Orange to push an update.
Yes, or you could flash the 303 generic UK and ota to current. You'll then get jelly when Sony says not ee.

I wonder how I flashed my V with its locked bootloader to Xperia VL's firmware using Flashtool, then.
All you need is matching signatures, and all similar models share them.
Yes good news

Sorry but you've got that wrong, you can use flashtool to flash an official ftf onto a phone with a locked bootloader, I've done it loads of times with my xperia's. In essence if your locked to a network orange, t-mobile ect then you can get the region generic ftf and flash it with flashtool to debrand your phone
What you can't do is flash custom ROMs which require a custom kernel.

Thanks for the responses guys, I thought it would be possible, the only reason I ask is that I've flashed ICS firmwares to the T in the past, but wasn't sure with it being a different version of the OS.

Please read before continuing to facepalm yourself.
Flashtool does not require your bootloader to be unlocked. It also does not even you require your phone ot be rooted.
Flashtool can be used on any xperia phone regardless. It does not require fastboot

Not always, there are ways around it. But in general yes.
Once the new firmware hits users with locked bootloaders we will see if we lose root, but then we will also find a way to root the newfirmware or find a way to update that does not lose root.

SP noob, need some guidance

I bought a Xperia SP today, awesome phone, love it. now i need to root it. i heard it needs to unlock bootloader first to room and if i did that im going to loose bravia engine and track id. so i need to find a trouble free way to root it.

This is my understanding too. Bear in mind that as soon as official updates are released a developer here will make it available on xda. This means you often get updates before you would normally (because they are rolled out at different times depending on carrier and region).

Usually a carrier locked xperia has a permanent locked bootloader. Don't be surprised if you can't unlock it.

It is an issue if you want those highly customisable roms such as cm,pac etc. I rather lose be2 than not having the chance to flash those. But now there's a way to save your ta before unlocking bootloader so it's all good for those who want to unlock bootloader and still keep be2 for future use.

Yeah viper rom was always great in htc phones. I know not it since htc sensation. CM always seemed broken. Always something isn't working what works on other roms. I always wondered why CM always seems to have issues with things.

I have an Xperia SP currently running 4.1.2 rooted, bootloader locked.
My aim is to upgrade to 4.3.3 and root, for which i will have to unlock the bootloader. To do so I need a TA partition backup , for which again, root is required.
So, my question is that is it okay if I take a TA Backup now [in 4.1.2] and then upgrade OTA and unlock bootloader, root and then restore the 4.1.2 TA backup onto 4.3.3 in order to restore DRM keys and Relock the bootloader?
Has anyone done this?
is it safe?

I've got a Sony Xperia z1 which I will be selling now and I need to get it to factory settings. Im currently running CM11 and am rooted, unlocked bootloader and have a custom recovery. Are there any guides that will get me back to stock firmware and is it possible to get it back so that no one knows it was ever rooted ?? When I unlocked the bootloader I backed up my TA partition.

you can flash the latest official firmware via flashtool(root,recovery gone) than you relock your bootloader and use the TA partition.

Well, warranty fraud is not condoned on XDA. I have told you how to relock your bootloader and return your phone to a stock state.
If unlocking your bootloader voided your warranty then its voided no matter what you do after that,
