The LED is all you get. The screen stays black for fastboot and flash modes. Not sure why adb devices isn't working.

one thing weird

i using a Xperia Tool (Xperia Companion) and it display the text that my phone need to unlock the screen or allow to use data tranfer

which i already check a USB debugging to be on, and every time i connect it to my PC, it still ask me a permission to be allow or not

maybe this is a problem here ?

It cant be listed in ADB if the android isnt running.
Blue LED means fastboot mode. So to check if the device is in that mode you do "fastboot devices".
Once the LED is blue you can unlock the bootloader with the command "fastboot oem unlock 0x<insert your unlock code>".

When I pressed to volume up button and plug the cable in, led turned red>blue>off. I tried releasing the button at a different colour, but my phone still did not go into fastboot mode. Did I do something wrong?

I guess you are using windows. This is issue on windows when you don't install adb drivers. There should be tutorial on Sony site how to install them.

Yes, I am using Windows 10, but let me clarify my understanding first.

From what you said, I need to manually install the ADB driver by Device Manager > Portable Devices > Xperia 10 Plus > Browse my com... And that driver, I should get it from Sony site, but I only see Xperia 1, 5 and 8, not 10 nor 10 Plus.

However, I could see my phone by using command adb devices through minimal ADB and Fastboot. Does this imply that the driver is installed already?

Adb and fastboot are not the same thing so you have to get fastboot driver.
I have no clue where this driver is as I use Linux only which includes the driver by default.

I see. There is a fastboot driver on Sony site, but it was uploaded since 2014. I successfully installed it, but still nothing seems to work. I will try on Ubuntu later. Thanks for your help.

I was using windows 10. From what I can remember, my problem is that I didn't install driver correctly (I'm not sure which one). I am not really sure if this fastboot driver the one I used. I saw my device in Device Manager, but I got waiting on device... just like you. So what I have done was locate my device in Device Manager and install the sony driver over that device. If sony's driver was not the correct one, then it was another driver that I can't remember, but the instruction still the same. Sorry for an unclear message, but I can barely remember anything now.

Go in Windows Device Manager and check the device . If needed install drivers manually
