@MrT10001 Yes, we unlocked bootloader and we have status ,,unlocked''

@sony Are you in Fastboot mode and does UBPorts Installer detect your device?

[sony]

@TakoR UBPorts detects my device but I don't know if it is in fastboot mode.

@sony When trying to connect the phone to the computer and the phone is still turned off, hold down the volume down button while connecting to the PC using USB and the LED should turn blue. If it's blue, you're in fastboot mode. The UBPorts Installer should be able to see your device. Cheers.

@TakoR I did what you wrote and still got this error

[MrT10001]

It still looks like the bootloader is locked.

If you have unlocked the bootloader have you done this:

Download the OEM binaries for AOSP from sony, unpack them,
Flash them in fastboot (fastboot flash oem [filename])

@sony Yes, I agree with @MrT10001, your bootloader might still be locked. Unlocking the If you get an unlock code from Sony, don't forget to add the 0x as a prefix. It's not in the manual but that worked for me as the unlocking sequence only accepts 0x in the front. Cheers.

I made it, thank you for your help.

Hi @sony,

@sony said in Xperia X can not open bootloader:

@MrT10001 Yes, we unlocked bootloader and we have status ,,unlocked''

It is not apparent to us where you read the status "unlocked" from, because further down in the post you write you don't know if you are in fastboot mode.
What does your device show, check the status via the bootloader, similar to the picture

The error message, of the Ubports installer, is strange if the bootloader jam would be "unlocked".
And please give us more info about what you have already done, and in what order. Or are you just waiting for us?

Greetings Mario
