Firstly can you tell me where you bought your device from and if it was brand new or used.
Apart from that the answer is that the difference between a locked and unlocked bootloader is a locked bootloader doesn't give you the ability to root your android device or install custom roms(custom android versions) while on the other hand, if you have a unlocked bootloader you are able to root, install custom roms and basically just modify your android phone. Although there are catches of unlocking the bootloader such as:
You will loose DRM content
You will loose some fuctionalities of your phone that are carrier specific
You will not be able to PROPERLY re-lock the bootloader in case you are thinking of doing that it is possible but you still cannot recover the lost DRM content
You will loose the ability to do FOTA(firmware-over-the-air)upgrades.
That is basically what you will not be able to do.
Although, in my opinion i recommend not unlocking the bootloader yet because the stock android on the phone is brilliant as well as that in the beginnig of April we will be getting the ICS update for our phones which would include nice features like face unlock improved camera app and other major changes which will be good. So i think it is better to wait till then rather than jumping the ship
If you were wondering it is safe to sim unlock your phone(if its locked to a specific network) since you will not loose any functionality of your device. I recommend rooting only if you are going to overclock your device or don't like how it runs if that's not the case then i don't think you should.
You don't need to unlock the bootloader to root your phone and rooting it has no effect on whether you can upgrade or not. If you don't root it you're very limited in what you can tweak and virtually everything on this forum relies on it.
Unlocking the bootloader is only necessary to change roms to cm7, miui etc

Just one more question, is there any thing difference between a new phone and a relocked phone? Thank you.
Thank you.
No one ?
Hello, I have been waiting for 1 month
dont know if you can relock bootoloader.
Difrence is that if you unlock bootloader you will never ever be able to have mobile bravia engine, track id and some sort of stuff.
Unlocked bootloader can instal cyanogenMOD (custom ROM, which is powerfull and good)
Locked cant do that, but can recive Sony Updates
Up... same question... we will be able to relock our arc s? Please answer!

Well It looks as if I Cant remove unnecessary apps on my Arc without rooting.
But here is something i wanted to ask before I go ahead with doing That
Q1) Is it necessary to Unlock My Boot Loader for Rooting or Rooting can occur without Unlocking it aswell?
I mean that I have read rooting without unlocking it but will it be the same locked or unlocked?
Q2)Unlocking My Boot loader means a 100% surety that my warranty will be Nulled right? (I Live in India, Rules don't differ here or in UK does it?)
Q3) If I have Rooted and NOT Unlocked my Boot Loader, Can I still update my Phone software through SE PC Companion? And Is my Warranty Still Safe?
Because I read that ICS will be available for Arc in the first quarter next year so I want to update my phone using SE PCC and NOT by flashing even though I know the pro's of flashing
Thank You so Much!

1. No you dont have to unlock BL to root your arc search for doomlords easy rooting toolkit
2. As far as I know yes
3. Yes you can still update with SE PC companion but I think updating via PC companion removes root. And your waranty is safe
You can use zegrush to root without unlocking bootloader. I live in India too. U can still update after rooting but not after unlocking. Rules apply everywhere.
Xperia Arc (rooted)
Thank you sooooo Much!!!
One more question
@Tatit1011- in reply to ur question 1, are dere any pros/cons of rooting after unlocking BL and. Rooting without unlocking it??

If you unlock your bootloader you CAN: flash custom roms, kernels(for overclock), and generally anything.
You CAN'T: upgrade via se, either pc or ota via the phone. Plus drm is lost, as is your warranty, but you can re-lock it
Generally, if all you want to do is remove system apps and use apps like titanium backup, root explorer etc then just root. If you want to try custom roms(there's only one you can flash over stock kernel, I think) then unlock the bootloader.

Hi.I'm going to buy an italian xperia play branded TIM.
My question is:Can I flash a general firmware to debrand the phone and than unlock the bootloader with fastboot?
Can someone explain me how to do these things?
Thanks very much
Think the 1st sticky thread at the top of this forum should answer all your questions!
well.
my last question.
If i buy a branded xperia,can I flash a general stock firmware non branded after i installerd Clockworkmod for locked bootloader?and next,unlock bootloader and flash doomkernel?
A better way to do that is just to not flash the CWM for locked bootloaders. The reason being that doomlords kernel includes CWM in it already, I'm not sure how the locked version is stored or whatever but you might run into problems if you have both "installed".
So there is a Doomlords kernel for locked bootloaders? mmm..this is a good news.In fact i wanted to flash CWM first because i thought that i have to unbrand my xperia and than flash another kernel.So i can buy xperia branded and install doomkernel? or i have to:
by xperia-install CWM-unbrand Tim-Unlock bootloader-remove CWM-install doomkernel? excuse me for noob
easiest way to debrand your phone: search Wotanserver on google and use their software to debrand (really esay, there's a step by step guide), then do whatever you want...
No, how it works is you have to unlock your bootloader in order to flash a kernel. As for unbranding you can either use the Wotan server or a .ftf file, neither of these require an unlocked bootloader. You can also flash CWM with a locked bootloader, however this is not the one included in doomkernel, and it will not grant you the ability to flash ROMs as you need an unlocked bootloader to flash the kernel. You want to touch the kernel? You need to unlock your bootloader. Unbranding? You can simply use the two methods listed above. All I was saying earlier is that if you plan on getting your bootloader unlocked (which in most cases is going to run you $24) theres no need to install the locked bootloader CWM first as once youre unlocked you can just flash doomkernel and already have CWM installed.

ok thanks.i heard that the italian xperia and not the verizon ones can be unlocked with an official method released by sony
Yep thats true, it's the case with a lot of r800i's, if you can put your phone into fastboot mode (turn off, hold search button, plug into usb, blue light comes on) you can unlock it for free through sonys online tool. While the light will go on for the CDMA version you don't have an IMEI to enter on the site so it wont work. All other plays CAN be unlocked, but its not free, you need to go through a pay service to enable fastboot.
Very thanks!however one of my friends bought an xperia and it was GSM R800i TIM and he was able to debrand and unlock so i think that also i can unlock my future xperia,or almost i hope it
Ya it all depends on where you get it from, but keep in mind it only costs $24 to unlock, so even if you find one say on eBay thats cheap but locked to a carrier, you could still just pay $24. That being said they're going pretty cheap now so I don't think you'll have a problem finding one, unlocked or otherwise. As a side not though, you don't need to be unlocked to debrand the phone, you just flash a different firmware file .
and so i can flash a generic firmware with flashtool or similiar?without installing CWM for loocked bootloaders?that's simply excellent!It's can't be better Ok,i will buy an xperia play and not lg optimus dual,that i simply hate xD i don't want a super-power phone,with a bad designe and without the pad.i loved,i love and i will love pad in gaming
Yep you can flash firmware, install CWM, and root, all without unlocking the bootloader (not that you need one to do the others). Unfortunatly the more fun stuff does require an unlocked bootloader, ie overclocking, undervolting, custom ROMs, etc. Anyway you always have the option, so read up on it and decide if you need it or not, regardless, enjoy your new toy
Hi all,
I've got the Sony Xperia S and unlocked the bootloader and rooted it once and flashed it with the AOKP, but that didn't work, so I tried the Cyanogenmod 10.0 (Jelly Bean). In summary I think it was the wrong Combination of kernel and custom rom, because it didnt boot anymore and got stuck at the logo.
So I closed the bootloader again and installed the official stock rom from Sony, and all got fine, luckily.
With some more reading into right forums and better knowledge I got the right custom rom and kernel and tried to unlock the bootloader again, but suddenly it didnt work.
Message: Failed (remote: oem unlock 0xF (und noch mehr F) )
I did all with fastboot and the right adb drivers, the phone is installed correctly.
Yesterday I asked for my problem in a shop and the guy said, that the bootloader of any Sony device would close completely, if the (right or wrong) unlock code is used for too many times (like the limit of 10 times).
If he's right, I've got a big problem. But can't I open it with an alternatvie method? Or is there just any mistake?
Thanks for any answer
Chriszo
i dont know, but ive already relocked and unlocked many times without error ,
try to do it again and be sure to input the correct 0xKEY
CM10 contains it's own kernel so could never be a wrong combination of rom and kernel. Did you actually unlock the bootloader or just root the phone? Sounds like your bootloader was locked and you were trying to flash still

Thanks for the answers.
I don't still know what constellation I really tried to instal the kernel and firmware, but I think it was an advanced stock kernel and then the firmware of the aokp. After that I tried the Cyanogenmod, but the device just didnt boot, there was only the logo.
I remember to have taken the kernel named ics17.elf and the advanced stock kernel with the official 4.0.55 build number.
The the device was rooted and the "sd card" was not wiped, but the data of the apps were deleted.
So the bootloader was open because the kernel can't be flashed with a locked bootloader.
After that I flashed the aokp and then the cyanogen mod.
Because of no booting I relocked the bootloader and installed the official firmware from sony.
Since then I try to unlock the bootloader with this damn error
I try to unlock with another computer. Maybe it work and its a simple solution. To unlock my bootloader i need to use my wife´s laptop.... i try in my compputer many times, install drivers, uninstall, and a lot of tricks but fastboot give me "error" all the times... lol
I just chatted and called with the Sony support (nice to hear great english at the phone ) and again got to hear, that they aren't able or allowed to give any information about the bootloader because of the possibility to loose the warranty of the phone.
I dont know really where my problem is but I think the code is not working any more, although I cant imagine of that
Is there any other way to do that? Or do I just do a stupid mistake ???
Thanks
Chris

No no no!
Another guy on xda did it with FlashTool on locked bootloader. I was able to do it until the logo...
Apparently you only can flash roms I think, not?
Anyway Sony supports Open Developer Community as well, they give you info about bootloader here:
unlockbootloader.sonymobile[dot]com
No, I cant flash any rom, therefore I need an unlocked bl. And the stock rom from sony isnt available in the internet, just with the Sony-mobile-update-service.
Well, of course I tried the way Sony dicribes on this webside, as explained below -.-
Got the solution ??
Hey I have the same exact problem and i did the same things as you did ... did get a solution?? please inform me if you did.....
Hi guys,
I've tried everything, but after successful root I can't unlock bootloader and flash recovery mode. Fastboot is also not running. The stock ROM is awfully slow and I wanted to flash a new one... That is what I see when I enter the service menu (see the attachment) :/
Please, help :c
Xperia S LT26i (2012, I think)
Its just not allowed to unlock your bootloader.
Nothing more to say.
Send thanks to Orange, where you device is from.
You may try other ROMs based on stock one, but optimized. As said above you can't do anything about it. I would suggest you to update the phone to a new one with unlocked bootloader, SXS too old nowdays with it's S3 CPU.
