[Q] Failed to unlock bootloader

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.

Install Kernel on a Locked Bootloader

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"...

Can't install update 14.5.A.0.270

As it says in the title, I can't install the new software update.
Oddly, I'm still on the latest KitKat because I didn't got the earlier lollipop updates.
If I try to install the new update, it simply reboots and says that the Installation failed, nothing more like an error code or something else.
I don't think that a previous Custom ROM, which I erased with Sony Emma, bothers that, but if it would, there you go.
Here are all the specs:
Model info: D5503
Software version: 14.4.A.0.157
Previous installed ROM: CyanogenMod 12 (not 12.1), erased and stock restored with Sony Emma
Internal Storage free space: 8.3 GB
SD-Card free space: 24.16 GB

i'm having the exact same problem. already tried flashing nordic and baltic but none of them work. hope someone comes up with a solution.

Xperiafirm fault. Solution:
After download and extract rom don't bundle it. Firstly remove from folder one file fwsomething.xml I don't remember exactly name of file but is one file with that name. Delete it and after that create bundle with flashtool and after that flash and everything will works superb!

fwinfo.xml was causing the issue, fwinfo.xml will be used by the next version of flashtool to create a FTF. just need to remove it from the FTF. anyway, thanks man!

I'm having the same problem, I previously tried rooting my Xperia Z1 (C6903) but it is now restored. However when I tried updating to 14.5.a.0.242, it said "The device contains modified software that cannot be updated". Is it because the phone was not restored properly? (I restored by flashing Android 4.4)
Regards

Did you unlock your bootloader...? Is it still unlocked....? If so you need to relock for OTA updates

wouldn't relocking bootloader cause problems (besides preventing flashing and root)?

No... locked just means restricted access same as a locked door.... but your device needs locked B/L to take an OTA Sony official Stock firmware update.... personally I would never wait for the official release if I have unlocked B/L I would always search and you can find firmware updates a lot quicker than everyone else waiting for the OTA on their device or thru PC Companion,
I use this very handy tool to get available stock firmware for Xperia devices
Relock bootloader only
If you want to relock your bootloader (e.g. for downloading official sony updates in Sony Update Service) you can do so with flashtool. This only works if you already unlocked the bootloader with the official method.
Note: This does not restore the DRM keys. If you have a warranty issue you should restore your TA parition (which will relock your bootloader and restore DRM keys) with Backup TA.
1. Open flashtool
2. Click on the BLU icon
3. Connect your phone in flashmode (hold volume down and plug in your USB cable)
4. Flashtool will ask you about the device model, choose Sony XPERIA Z1 (if Z1 compact is not in the list)
5. Flashtool will read your IMEI and your unlock code. Check if those are correct (compare unlock code with the one you received by email from Sony when you unlocked the bootloader)
6. Flashtool will save the unlock code in its program folder under custom/mydevices.
7. Click "Lock bootloader" (-> If you want to unlock it again, repeat the steps (it will automatically detect that your bootloader is locked))

Thanks 160lightning. I was just wondering, since I'm a quite new to Android and I just saw the Android 5.0.2 update but was unable to update

[Q]T3-D5103 flash T2 Ultra soft

Hi,
Can we (T3 users) flash T2 Ultra Sony's stock rom from tft? Has anyone tried it? Both phones have the same SoC. Sony does not say anything about update T3 to 5.0/5.1.1 . I can't flash custom rom 5.0 or higher because I had a Orange branded phone (locked bootloader; "Bootloader unlock allowed: No") only tft can resolve problem with newer soft.

It doesn't work. After flashing it the phone doesn't boot from what I remember.

Did you unbrick it? Tell how you do it.

I didn't flash anything, it was someone else from the forums who tried it.

It'll not gonna work... But if u can port for T3 it may boot but still u face some major bugs
