and
3. can if i relock my bootloader will networking functions work again if the network problem shows up?

If you unplug your phone while unbricking you can get a bad brick. Nothing bad can come of it really. And yes you can relock your bootloader

I'm using WT19i.
Just wanna ask a little question here.
1. I know that update OTA after unlocking bootloader can cause hard brick. Is anyone here ever hard bricked WT19i in another way?
1a. Why is that thing happen?
2. Is there any way to turn hard bricked phone working again?
Thanks a lot
Yes, people have bricked their phone earlier. Check my tutorial, link in signature, there is guide to unbrick.
It happens because OTA update tries to edit certain files in the ROM and kernel, but since bootloader has been edited(unlocked), files will not be properly edited, causing device not to start.
Only happens if unlocked via official way, test point method doesn't unlock bootloader, it only patches it to allow custom stuff to be installed.

I mean in another way. Not that because OTA after unlock bootloader.
Thanks for response. Sorry for my english
Hi all,
I've read a couple of stickies, and been through quite a bit of threads here at XDA, and I still can't find my answer. I hope that this is the right place for questions, if not, please excuse my ignorance and move it to the correct forum.
Here's my problem:
I have an Xperia Mini Pro (SK17a), locked to Rogers. It's one of the phone models that don't have the ICS upgrade. Perhaps I can blame that on Rogers, but then again, I can blame a lot of things on Rogers. I've been waiting for the ICS upgrade for quite a while, and now I'm just going to take this into my own hands and install a custom rom.
My understanding of this is that unlocking the bootloader will make my life much easier, and it's what I intend to do. The thing is, I'm SIM-locked to that god-awful company Rogers. From my 'research', I've read a bunch of stories and stuff, but nothing that gives me a definite answer. Do I have to have my phone SIM-unlocked to unlock my bootloader? (For either the official SE unlocking service and Test Point method). Will SIM-Unlocking also sever any bonds that connect my phone to Rogers? If that's the case, then I might just be able to update via PC Companion, which I can settle for if it takes less work than unlocking the bootloader.
My efforts in trying to update via FlashTool (and the official ICS .ftf) were futile, resulting in Flashtool giving me an unsatisfactory "ERROR- Error flashing. Aborted", which I think may be because my bootloader is locked, or I'm SIM-locked to Rogers.
(Using the latest version of flashtool)
Currently, my phone is running the latest stock Gingerbread, with root and CWM.
This ties in nicely to my next question, regarding Recoverys.
When I read the thread pertaining to CWM on the Mini Pro, it said that it should only be installed on a stock rom. Would this mean that CWM isn't used with custom roms? I find this to be stupid, as then you wouldn't be able to access the Recovery menu when **** actually turns bad, and you've got to flash a stable rom in a pinch.
That's all for now, thanks in advance.

P.S.
I'm not too much of a noob, so I can understand all of this crazy Android lingo; I've rooted/installed custom roms on my fair share of devices. On the other hand, I'm no pro either.
I know that bumping is generally frowned upon, but I'm doing it in hopes that perhaps somebody that could answer my questions just missed my thread.
Again, my apologies.

Same problem
Man I have the exacttt same problem and doubt as you do, specially about the SIM LOCK, I want ICS on my phone too, I have the same model. Have you gotten any answers?
well you can unlock your boot loader and install custom rom and after unlock you will unable to update through seus or pc companion until you relock the bl. i suggest u to use test point in this way you will not lose drm keys. and if there is a problem in network try different baseband.
Before unlocking bootloader you must remove sim-lock. Basically it comes down on buying sim unlock code.

I had no problems flashing ICS via flash tool on my then locked bootloader, sim locked device, so I'm thinking that's not the problem here.
Make sure you have installed the right drivers for your device, that it has usb debugging activated and that it is configured to msc (usb storage) when flashing.
Also, when I unlocked my bootloader via paid method (alejandrissimo) it also eliminated the sim lock :beer: I think it's part of the process. Anyway, maybe you could explain a little further about the error log you get on flash tool.
Don't forget to click thanks if I helped.
Edit: about cwm, of course you can use it on custom roms, some kernel even have that included. . First you install it on your stock ics and then you get to flash other roms.

I have a sim locked phone and the bootloader can't be unlocked because my phone was made in 12w22. No test point and no sony options because the status of the bootloader says Bootloader status: no.
The question is: if i by a sim-unlock code the bootloader status turns to yes?
i really need to unlock bootloader because my battery is causing me nightmares!! thanks for the help. sorry for the bad english(or not) .I'm portuguese
Hai. After 4 months I decide to Unlock Bootloader in my SE Lww (WT19i). But i`m still afraid. Can U answer my questions?
1. Is it possible to brick phone after bad unlocking BL? I`m going to unlock by this method http://forum.xda-developers.com/showthread.php?t=1560613
2. Can I unbrick phone after bad unlocking bootloader and how I can do it ?:fingers-crossed:
Yes you can unlock your bootloader successfuly with this application. You will have to provide you IMEI no minus the last no. There will be no problem unless you pull out the cable or do something stupid. After unlocking remember to flash the correct kernel for phone.
Also backup all your data and apps as unlocking the bootloader will require to wipe the /data partition.

Oh really? Thank you. But I have one last question. For example i`m unlocking bootloader and the power will off. What i will have to do. Re-flash soft with flashtool ?
If it boots up without any problem then you won't have to. If it gets stuck then you will have to flash a stock ftf file via flashtool. But mostly it won't. Anyway unlocking just takes about 5-7 seconds. Atleast for me it took that much time.

I'm thinking of unlocking my bootloader. I've checked that it is possible for me, but I just have a couple of concerns about doing so and wanted to ask about them here, before I proceed with the unlocking procedure.
First off, I remember reading that with an unlocked bootloader, you are able to brick the phone completely, is this correct? How vulnerable will the phone be and is it easy to brick, will something go wrong easily?
Secondly, can you install roms that have been developed for the locked bootloader even when you have an unlocked bootloader?
Hmm... unlocking the bootloader voids my warranty but I remember that there were tutorials somewhere to re-lock the bootloader. If I lock it again, will my warranty be back to normal? (Are there traces that I have messed with the bl?)
I think that's all. Is there anything else that I should keep in mind before going ahead with the procedure?
Thank you in advance for your responses! Happy Thanksgiving!

There will be no traces only Samsung traces such things
You will not brick it but you should follow all steps correctly

If you follow all steps, you cant brick your device
With unlocking, you loose data - something like factory reset - so save your messages and contacts.
With data, you will loose DRM keys too - relocking wont give back these, keys are lost forever.
But with unlocked booloader, you can install new kernels..
And roms for locked bootloader? For example, there is cm9 for lockedBL and for unlockedBL - i would not worry about this.

I'm not sure it's the easiest way but you can go to fastboot with method wrote here http://forum.xda-developers.com/showthread.php?t=2221102. But first you will have to flash jb V20* ROM. If you have first screen where you are asked if you want to unlock bootloader = locked. If second screen with quick guidance = unlocked.
WARNING! Be careful if you don't want to unlock bootloader watch which button you press.
You still didn't answer his question. I would like to know as well. Is there a way to tell if my bootloader is unlocked or locked?

Of course it's locked, every phone you get will have bootloader locked. Unless you have an S4 or S3 as far as I know.

As far as I know, not every phone comes with a bootloader closed unless some phones are able to change roms and stuff without needing to open this.
If your on JB, just go to the dialer and type 3845#*760# then scroll to the bottom to bootloader unlock check. (if you have differernt L9 - 3845#*7xx# - your numbers)
Another way to check is to go to software update mode by switching off the phone then holding volume up while inserting the USB cable. If your bootloader is unlocked, it will say so in the top corner of the S/W update screen.
If you havnt unlocked it, it will be locked by default.
