[SOLVED] Sony xperia 10 v - Linux fastboot challenges

Devices
1

Hi, all,
I’m after any tips or tricks for those who have managed to flash the xperia 10 v on Linux. I basically get a blue light, but Linux doesn’t see any USB device connecting.
What I tried:

  • Multiple computers, multiple USB ports (including a 2.0 one), external USB hub, multiple cables to no avail
  • It is noteworthy that adb does work when Android is running
  • Started an old[er] xperia 10 in fastboot mode, which worked fine
  • Booted my Linux with usbcore.old_scheme_first=1 to no avail

My kernel is 6.12.31, distro is Gentoo.

Thanks for any helpful clues/questions :slight_smile:

Solution (ish): you can read the history of the post, but basically this

As observed in dmesg? Or are you expecting something more fancy to happen?

Tried just now on 6.14 on Mint - no issues.

Yes, dmesg. I should have clarified :slight_smile:

Will give 6.14 kernel a go then, probably even some ISO of Mint.

Last i did it i was probably on some sort of 6.10 or 6.11, so shouldn’t matter.
But trying another distro sounds like a good test.

Can thus be related to USB 2 versus USB 3 issues? I read multiple times here that USB 3 can be difficult

6

It could, but I did try with a USB 2 port.

That only ever stopped usage of fastboot - not the detection part, as far as i’m aware.
(And it technically isn’t all USB 3, my dedicated card has always worked).
Also; i’m under the impression that Sony has fixed it for recent models.

Edit: probably not.

Side comment: I tried a USB-C to USB-C connection between xperia 10 running SFOS and 10 v and the 10 rebooted after showing something in dmesg :laughing:. The 10 v didn’t even start fastboot mode.

So, I have now tried:

  • Linux Mint (kernel 6.8)
  • Sysrescuecd
  • Windows 11 (through VirtualBox)
    …but nothing helps :frowning: The device works otherwise well.

UPDATE: I managed to unlock the bootloader by adb reboot bootloader and/or recovery mode (power+volume down)->fastboot->bootloader and alternating USB cables. I had to do something similar in the middle of flashing. Not fun, something is very fiddly with my device :confused:
