Everytime i try to unlock the bootloader it says the bootloader is already unlocked but its not
I looked everywhere but i cant find the solution so i came here in hope someone can help me.
If it says that it is unlocked then it actually is. All that you get from unlocking the bootloader is the ability to flash custom kernels. UB itself gives you nothing apart from the ability to flash custom kernels.
thanks for the reply but i was flashing the kernel wrong now its working

i searched the xplay forum and general forum but i didn't quite find what i wanted. What i wannt to know is how to unloack and relock bootloader.
idk if am right but correct me if am wrong
i know sony does the unlock bootloader on their website. so i know how to get it unlocked
now if i unlock my bootloader, i know that it voids my warranty and something about certificates but if i unlock it and flash custom roms and kernels and stuff. if sony decides to bring out there ICS update at the end of march and i want the update i would have to relock bootloader and reflash a stock rom & and stock kernel (depending on what i flashed)
and if so does n e one know how to relock bootloader???
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

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.
Hello guys, sorry because may be this is the 50th time someone ask this question but the situation change every day. Yesterday I won from lottery and decide to go from G3 to G4. My model is European H815, I want to ask you can I root G4, change the recovery and e.t.c. without unlocking the bootloader? And also if I unlocked it is their any way to locked it again or to use my warranty? Thank you!!
well you can only root using low effort root(google it or find it here ) But to change recovery you have to unlock bootloader
No there is no way confirmed to relock your bootloader
GOOD LUCK
Thank you! If I root by this way and download Flashify and try to change recover what will happen ? Thank you!
without bootloader unlocked nothing will chnage ( recovery wont be installed ) and when you reboot your phone it will get u error (authentication error #9) as i remember and you will have to flash new firmware using lg flash tool 2014 so i dont recommend you do so
if u wanna change recovery unlock ur bootloader
you are welcome anytime
I did not get it, I hope you can light me up:
1. Doing root using low effort root means rooting without unlocking bootloader? (because I flew over the thread and did not read anything about it)
2. If I do unlock Marshmallow's bootloader, what happens when I downgrade to Lollipop via flashing proper KDZ? (I would guess that the unlocked bootlader will be overwritten!? So flashing Marshmallow again would end up in a locked bootloader, doesn't it?)
thanks
You can root lollipop without unlocking bootloader but with marshmalow you can't, you have to unlock the bootloader.
You need an unlocked bootloader for custom recovery.
Bootloader unlocking is a one way operation , you can't go back.
i was wondering if i unlocked the bootloader and installed a custom rom i`m not willing to change soon, can i lock the bootloader again while i have this rom?

Certainly you can if you are prepared for a bricked device later. I mean, it is not advisable to lock the bootloader if you have a custom ROM since any issues arise later, you will not be able to solve them. In addition, even if you manage to unlock the bootloader again in such a scenario, you will lose all your data including files, photos, videos etc.
If you properly sign the firmware, you don't even have to unlock the bootloader, see https://forum.xda-developers.com/oneplus-3t/how-to/guide-custom-kernels-roms-recoveries-t3572525
