Re-lock bootloader, flash stock firmware and send your phone to Sony

I read that re-locking a bootloader with a custom kernel installed would brick your phone, is that not correct? I belive the correct way would to be to reflash your phone to stock using SEUS and then lock the bootloader?
I'm not saying that eagleeyetom is wrong, I'm fairly new to this type of thing but I do remember the unlockbootloader guide stating not to relock bootloader with a custom Kernel installed as you'd brick the phone. Just trying to help

thanks for help.
my touchscreen is broken. I wanna change it to the new one.
I should relock my phone, right??
Are they check the software?? I think i've got the hardware problem..

Yeah, you're right. You should first flash stock kernel and then re-lock.

thanks.. i'll try it..

Please clear my doubts..

hi all i am having many doubts regarding installing custom rom please help me...
my doubts are
1.Do i need to unlock my boot loader to update my baseband
2.Will the unlocked boot loader stay always so that i can flash many kernel and custom rom or do i need to unlock each time
3.After unlocking which case should i relock my baseband
i am sorry if these questions are very basic i am very much confused
1.No, it is nor required to unlock the bootloader to update the baseband.
2.Yes, it will always stay unlocked even if you restore with PC Companion or SEUS.
3.You should relock it if you are sending the phone for repair at Sony Ericsson.
First check manufacture date before proceding to unlock bootloader.

As said above, check manufacturingdate. IF above 11w29 then dont try to unlock. Chances are youll be ending upp with a brick.

If it is an offical update from SE, that doesn't need to unlock.
If it is kernel, rom bla bla bla from this FORUM, Mostly rom will need you to use the kernel, thus it is a must to unlock the bootloader.
So, if you're using original eclair, planning update it, there's is no risk except for electrical trip suddenly happen

if you're not unlock your BL, you can not flash your kernel.. so u can brick your phone..

I want unlock my bootloader, but..

Hey guys. So, I want unlock my bootloader, but I have maaaany questions.
This Xperia X8 was of my friend. He gave it to me. Time ago he tried to unlock the bootloader, it seemed to be successful, but he hardbricked the phone. Fortunately, the phone was under warranty, so he sent the phone at S.E . Now it is in my hands. :good:
First, I put custom roms. First, Froyo Pro, now I have MiniCM7. Now I want unlock the bootloader for a custom kernel.
I searched many threads, and I read this :
http://forum.xda-developers.com/showthread.php?t=1693308
Do you think this is good? I know that unlock the bootloader is dangerous, but this procedure is a little bit more safe?
My friend had followed another tutorial, but I think he failed because he was on PrimeHD when he tried to unlock, and in the PC : No PCC companion.
I read that, I MUST HAVE stock rom and PCC Companion. Is this right? I have MiniCM, if I use PCC Companion, can I have the right stock rom?
It is possibly to unlock the bootloader , even if the phone was sent to S.E for repair?
Now, in the battery I read 11w15, and in the inside of the phone,
IC: 41708-A3880091 FYT 12W08
It is possibly to unlock?
If yes, anyway can someone give me support?
Thanks guys
DONT unlock it, you could end up again with a hard bricked X8

[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

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

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?
Sent from my C5303 using xda app-developers app
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?

NO. You can't unlock your bootloader if 'unlock bootloader allowed = no'
Since you cannot unlock bootloader, therefore you cannot flash custom ROM on your phone.
Rooting phone do not always need bootloader to be unlocked. There will be some ways available to root your phone with LB.
Also there will be some ROMs available that can be flashed over LB. But they'll be based on stock and will not have more features rather than stock features.
You just need to search here on XDA
I suggest you not to flash any ROM on LB. You'll eventually get bootloops and maybe hard brick.

Nope! As much as I know, you cannot change status from 'no to yes' rather than changing your motherboard to do so. It'll cost you more than you buyed it.
It is related to TA Partition. And EVERY phone has its unique TA. So no one can change its status. Flashing other phones TA to your phone will brick your device.

In such case you need to roll back to your previous android version. I don't think you could unlock your bootloader. But if you are telling it was 'yes' before, then you should try.
No matter your phone works with every sim or not. TA Partition contains DRM keys as well as many other things related to network, warranty, services which get erased after unlocking bootloader.

Yes you can flash any stock ROM through flashtool. You just need to download appropriate firmware (.ftf)
Even you could update your phone through PC Companion. The latest version is 5.1.1 Available.
BTW why are you trying to flash stock ROM? Are you using any custom ROM already?

You mean bootscreen, right?
Just because of bootscreen are you going to change the entire ROM?
You could change bootscreen manually. Your phone just need to be rooted to do so. To root your phone use kingroot app. If your lucky enough, your phone will be rooted.
There are tons of bootscreens available. Just pick one and place it in /system/media (don't forget to backup old one) with -rw--r--r permissions and Bingo! You have changed your bootscreen.

Try the same app several times. It usually does not succeed in first attempt. It you fail each time, try kingo root with windows software.

Dude, your on latest android version. There isn't any exploit available to root ver 5.1.1
You either need to wait until anyone makes an exploit for your phone or you need downgrade your phone and root it.
There is a pre-rooted firmware available for lollipop But it works only if phone has 5.0.2 .
Unfortunately your phone has 5.1.1 that means you still need to downgrade your phone and flash pre-rooted 5.1.1
Also, your bootloader can't be unlocked. So you need to flash ROM accordingly. Don't ever flash ROM that are meant for unlocked bootloader.

when someone makes an exploit for my phone and root 5.1.1 . i steel need to unlock the boot loader ?

How to go back to stock and relock the Bootloader?

Hello
i have to sell my device so i want to get it to stock again.
My current Setup:
Bootloader Unlocked, Stock Recovery, Rooted with Magisk, Stock ROM 9.0.0.283
What are the Steps to go Back to Stock and wipe everything?
Ive read that if the bootloader relock again it is not able to unlock the second time? Is this correct? I want to get the Unlock Code to the person who buy it but if its real, he cant use the code anymore..
anyway is it possible to do the job with the Stock E-Recovery in the current state of my phone? Without bootloader Relocked? Or is it necessary to relock the bootloader again?
Thank you very much

Ask the buyer if they want it locked. Personally it wouldn't be worth my time if it couldn't be unlocked again. Better to check first..
If you want to lock (not relock) bl justdownload your adequate firmware from androidhost.ru and flash fw using Usb-otg method.
You can unlock/lock your bl using unlock code anytime you want (provided you haven't changed your mainboard in the meantime).

I thought you wanted to go back to stock. I've already gave you solution to bring back all the way stock.
I m not sure if it's even possible to re-lock bootloader using fastboot when you're on pie.
Bootloader status re-locked still means your warranty is void.

Hey I've tried this otg method but without success
If I try it with the dload folder option and try to force flash the emui updater throws an error.
Even with the dialer code method.. same..

I've tried the Huawei suite on PC and phone in fastboot mode..same..massage this phone can't be reset or so..
What can I do next?
Current state, halfway working phone that's boot into os 2 times from 10 reboots.
