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.

Hey guys could you please help me to solve my phone, when i flash LT18_4.1.A.0.562_Nordic.ftf on my phone and until now it keep restarting/rebooting on the sony page then black and then again, i can't even hard reset on it, can anyone give me a new ftf or anything that can replace that? All i can do now is flash and fastboot, i can't even go into safe mode
Try these http://uploaded.net/folder/8rfx7b is your bootloader unlocked?
Was the flash successful in Flashtool, unlocked bootloader?
Yes i was unlocked my bootloader from sonymobile.com/developer site and the flash was successfully loaded, but which link should i take, the Generic world / Generic DE / Nordic?
PS: i was first time rooting my phone >.<
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.....
Hello everyone, am new to xperia phones. I wanted to flash CM12 on Xperia M C1905. But am not allowed to unlock the bootloader. But I was thinking if there was a way just like installing recovery on locked bootloader. I also thought that if there was a way to convert an boot.img to kernel.sin. You would be able to flash the kernel via Flashtool just by swapping the kernel of the stock firmware. Or if someone could try to flash the unlocked bootloader of the of another C1905 on the locked one. It might work.
Does anyone knows how to unlock bootloader using testpoint method on the device?
Thanks in Advance!
.img .sin .elf, doesn't matter, a kernel can't be modified in any way without unlocking the bootloader
Even using it with Flashtool in Flashmode flash?
Does anyone knows how to Unlock bootloader by testpoint the device?
If you device has a permanently locked bootloader (e.g. bought it from a carrier or with a contract), there's no known way to unlock it and with a locked bootloader it'll only accept kernels/recoveries signed by Sony (even if you manage to repack CyanogenMod kernel in a .sin file, your phone would refuse it because it's not signed by Sony). Even if you find a test point in the board or a serial interface to flash another kernel directly in the phone's eMMC chip, it would still refuse to boot because kernel signature is always verified when powering the device. If it's not signed or if it have a different signature, phone turn off immediately.
For locked bootloader users, the only way of getting a custom ROM would be building a custom kernel with kexec support and hijacking the stock init procedure, making it loading the custom kernel right after the stock kernel. At the moment, the closest we got to that was the CWM recovery you linked but it barely works and only in the old 4.1.2/4.2.2 firmware. Seen Xperia M doesn't have many active developers, it's unlikely to expect custom ROMs for locked bootloaders in near future...
Yeah, you're screwed, no known way around that. As a future advice, never buy another Sony device from a carrier or with a contract

Thanks for your reply, that made me understand more about sony's phones. But I was wondering, the says that fastboot is usually disabled when bootloader is locked. But mine, I have access to fastboot and still bootloader is locked. But i did try to flash a kernel, and the following poped-up
FAILED (remote: Command not succeed)
Is this normal for me to be able to access fastboot? or the issue is with the device itself?
And also it was bought on eBay, no carrier device or contract one :/
Thanks in Advance!
Fastboot mode is always accessible, the difference is that with a locked bootloader, the only command that will succeed is fastboot oem unlock and only if your bootloader is unlockable. Otherwise, fastboot is there but it's useless because all commands will return "failed"...
I'm using Xperia m dual c2004.I tried to unlock the bootloader. Several times using the procedure given in the Sony developer, did everything correctly. But the phone goes into a bootloop after which the only option is flashing the stock rom.
I tried unlocking the bootloader the otherway by using flash tool but it doesn't have my phone's drivers. And the link to download them doesn't work anymore (found it in a thread)
The are no roms for lb for my device (plz tell me if you know any)
I checked my bootloader status by going into *#*#bla bla code then service tests and security And the service Status was active which means bootloader is locked.
When I go to service menu and config my phone's rooting status is showing bootloader unlocked.buti don't think it is ul but it just has the Permissions.
Please help me I'm not able to flash roms because of this.

When you successfully unlocked bootloader you should go to bootloader mode with key combination when restarting phone and install custom recovery. Naturally without loaded drivers in computer it has no sense to try it.
Hi guys,
I just got Xperia M from my friend to install on it some custom ROM and etc. but there is encrypted data and I cant do nothing with it.
I tried repairing software with Xperia Companion, but I get UEUpdateFailed UE_2005 error and cant get past it. I tried also to enter recovery, but there's no recovery. Dont know what to do, cuz I need to check if I can unlock it.
Thanks in advance
Hi,
I can't figure out what exactly is giving you trouble, so you might want to be a little more specific. So I don't know if this is helpful for you, but:
First, there is no stock recovery on the Xperia M. As long as you don't flash a recovery on it, there is none. So you won't be able to enter that.
Next thing, Xperia Companion is a software to update or repair the stock ROM. So you won't be able to flash a custom ROM with that.
Just backup the data (if the data is encrypted and still needed, you didn't say what exactly is encrypted) and use flashtool to flash a ROM.
I'm not sure what you mean with checking if you can unlock it. The encryption? The boot loader? SIM lock? If you can unlock the boot loader (and SIM lock status too) you can check with the service number, so no need to flash it for that. Or is the device not even starting up because of the encryption?
So I dont really know if I can unlock bootloader of that phone cuz I need to "you should confirm that it is possible to unlock the boot loader of your device by checking the service menu. In your device, open the dialler and enter *#*#7378423#*#* to access the service menu" but I cant cuz of encrypted data. When phone boots up it ask me for password, but I dont know it. When I tried to use repair function to flash stock software and then the encryption would be gone it gived me error mentioned before. I dont know any recoveries or Roms that I can flash on locked bootloader. Any sugestions ? I want to flash newest Lineage OS at the end.
Is it possible that the boot loader is already unlocked? PC Companion is not working with unlocked boot loader.
You can also use flash tool to check if the boot loader is unlocked or not.
how to check that in flashtool ?
You switch off your phone, hold the volume down key, connect the usb cable, then it should be recognized in flash tool. Then you click on the lock. It should tell you the state of your boot loader somewhere there.
