Hello, I recently acquired an Xperia S, I love this phone, the screen is absolutely beautiful and it has the ability to be fast ! But, I got a problem, that, apparently, even in this forum, nobody can resolve : I rooted my phone and I installed the CWM6 recovery... but now... I want to install a KitKat ROM, and to do so, I need to unlock my bootloader, unfortunately, despite the fact that my phone is sim-unlocked, my operator still have control on it because I heard that my bootloader cannot be unlocked, I can't even use the fastboot mode because of my operator stupid restrictions !!!!!! :crying: Please, you're my last hope, do someone got a solution to my problem, even a solution that is costing money, I got to use a CM10 custom rom for non-unlocked bootloaders to survive actually, I can't wait longer... Thank you !
We all want to get it.

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

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.
*apologies for any obvious information I may have missed*
I have a Moto Z Play that has a locked bootloader. I've searched through a lot of these forums, went to other sites, and I've still not found the information I probably should have by now. I want to put the Resurrection Remix Rom on my phone, but I'm confused on a few different points. The phone was given to me and it looks like it was Verizon before I got it, and I use Straight talk as a carrier. I've seen the unlock process on Motorola's page, and it says my bootloader is not eligible for unlock. With the capabilities of a lot of these developers, I find it hard to believe this means the end of the road. My question is whether I can wipe the phone and somehow unlock the bootloader? Is there anyway I can speak to verizon to give me something to get an unlock code from Motorola? Can I put Resurrection on my phone without the bootloader being unlocked? Again, i've been reading and trying to figure this out on my own without having to make a thread, so sorry if this wastes anybody's time, but I could really use some help.
Thank you very much in advance.
If your phone is contracted with Verizon .... They they will not allow you to unlock the bootloader
To install custom ROM , you must have custom recovery ( may be twrp)
To be able to install custom recovery, you must unlock your boot loader
So both is not possible right now if your phone is from Verizon
So you can not install custom ROMs
Keep eyes on the MZP thread for solutions
Hope this helps
Before you ask me, yes i have searched through lots of threads and i only create a new one because i still cant solve this. Perhaps someone here knows.
I have an Arc S with locked sim and "Bootloader unlock allowed: No"; and i've done hours of research, tried to get the unique unlock code for it and i did get it but i can't unlock it because as its bootloader state is "No" i cant get it into fastboot mode. So later i found i could only do it with that paid method of omni something which is about making a bridge in those contacs under the Sim.
So up to date, almost 2018, do i still have to pay more than this phone costed me to get a quite decent user experience with it? Because i wont.
I would really appreciate if anyone knows a method to do unlock BL with my current status. Thanks!
Edit. I gave up, im just looking to get a new GB rom that works in a locked device (now rooted btw) because flashtool doesnt seem to like 4.0.4 roms and i get system.sin errors while flashing any rom that is not 2.3.4 .
So does any of you know a rom that at least has a working download link? 70% of threads i search about this cointain dead links.
No Xperia Companion does not recognize the device (yes tried lots of things like debug on and off) and the PC Companion client that the phone comes with from factory always gives error while installing, so im pretty much stuck with ginger bread .ftf from the webs and flashtools. Thanks.
