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..

Questions From a Would be Owner

Hello guys,
Just a few questions so I know what I am getting into
1) The phone can be rooted. However, if i want to run on a custom ROM or use mods such as the music mod, I would have to unlock the bootloader, yes?
2) Once the bootloader is unlocked, I would lose the 'Bravia Engine' feature of the phone. What else will I lose? For those who have lost it, is the trade off, of being able to run Custom ROMs and mods while losing the 'Bravia Engine' feature worth it?
3) If I have to send the phone for warranty, I could just re-lock the bootloader and send it back for warranty. Is there a chance somehow that they'll reject the phone if they detected that the phone's bootloader was tempered with?

No clue since mine isn't/can't be unlocked. The only reason for me to unlock the BL (Even though it can't be done) would be, to flash a custom kernel, beside that I don't see any other reasons why I should unlock it.

Once it's unlocked there is no way back.
So if you want to root your phone, use custom roms (without custom kernels) you don't need to unlock the bootloader.

Thank you very much for the reply.
I assumed as such from reading some posts initially, but then I went to the ROM section (If i am not mistaken) and there is a post on how to unlock the bootloader and then there is the Why section where it says that you could then use custom ROMs and mods which then confused me.
If i can use custom roms and mods without unlocking the bootloader, then I'll definitely be getting this phone.

I'll take advantage of this thread to ask one simple question: once we rooted the XZ and flash the Mods we find useful, we no longer get updates from the official Sony firmware in the future, right?

First backup your firmware with http://forum.xda-developers.com/showthread.php?t=2188129
You can go back at any time to your original firmware and you can have the updates via pcc or sus.

1) You dont need to unlock the bootloader to root, towelroot method will root phone just fine
2) Unlocking bootloader caused some issues in BE but if you are just rooting without unlocking there wont be any issues
3) Unlock bootloader only if you are planning to flash custom roms(Remember unlocking bootloader WILL void your warranty)
4) Flashing custom kernels and roms is risky business so please read up before doing anything

Nope, I just sent my XZ to repair service for broken glass, BL was unlocked and I didn't even re-locked it before sending to customer service. Everything went fine, repaired, ROM updated and still under warranty.

Broken glass was a "hardware issue'
If your phone goes kapoot(Hard brick) while tinkering with roms or anything software related and your BL is unlocked chances are the service center might not honor warranty as it will be a "Software issue'

Sorry I know I'm late but it can be helpful for some to make some precision about warranty...
I said that because lots of peoples always think as long as you unlock BL warranty is lost no matter if it's software or hardware related.
Even Sony website says on unlock bootloader official page "warranty may be voided".
I'm sure there's Xperia owner that doesn't bother sending their smartphone to repair center just because they think it is useless as they unlocked BL...
Now if they read this they know there's always a chance to repair under warranty.

CANNOT UNLOCK BOOTLOADER please help

hey i cannot unlockbootloader in service info bootloader not allowed which frimeware i can unlock bootloader?

hi there,
if the phone says in the service menu bootloader unlock allowed no means it cant be unlocked but that means you can still install a custom rom which should say LBL rom. Follow this guide: http://forum.xda-developers.com/xperia-sp/general/guide-flashing-custom-roms-ultimate-xsp-t2888579

Go to Xperia website, and search Unlock Bootloader, there you can select Xperia SP and see the number code type it on your cell phone to see if your cell can unlock the bootloader ( My English is more less bad, sorry for this I am Brazilian )

If it says "no." you can't unlock it. You can install custom ROMs as long they are stated that are for Locked Bootloders. Do not attempt to flash a ULB ROM onto a Xperia SP with a LBL because it will soft brick your phone. Attempting to unlock the bootloader when the the status says "no" it's not recommendable and could hard brick your phone.

As mentioned above, if the phone says "no" or doesn't say anything at "bootloader unlock allowed:" thing, then there's no way around that. You can still get custom roms though. There are some roms that will work with locked bootloaders.
Pro tip: Always buy generic phones if you want the best from xda. Always check what you're going to buy.

Get unlock code on already unlocked (and rooted) device

Hi,
I have a VIE-AL10, firmware B183. I am trying to update to B195 but I believe I cannot do it because I unlocked the phone.
I don't need the unlocked bootloader anymore (for now) and my idea was to relock it and unlock it again in the future but unfortunely I have lost the code I got using DCUnlocker.
There is a way to recover the code in this unlocked and rooted phone?

U can update with unlocked bootloader but not if u have TWRP and root. If u have it i need to unroot and install stock recovery.

Thank you, I imagined that. Any way to recover the unlock code so that I can redo the unlock procedure after I upgraded the phone?
