Trouble unlocking bootloader - Sony Xperia XZ Questions & Answers

Sony instructions are awful, I downloaded both the Studio and the SDK tools and things are just... "off" ( f.ex., android_winusb.inf doesn't even exist anywhere in either Studio or SDK tools to be replaced with ).
So I downloaded minimal ADB and fastboot, and I'm having trouble getting the device to be recognized while in fastboot - in device manager, "S1 boot" is unrecognized - I've tried using the drivers I've downloaded from Sony to no avail. Downloaded Xperia software and flashtool, installed drivers from flashtool ( XZ wasn't included in the ****ing thing, of ****ing course it wasn't... ), same thing.
"fastboot devices" simply isn't procuring an answer, and trying to jump ahead and do the unlock, it says that it's pending for devices to show up ( obviously ).
Some help?

Try this guide: https://forum.xda-developers.com/xperia-xz/how-to/how-to-unlock-bl-kernel-twrp-root-t3541648
btw. Sony use custom adb/fastboot driver (link in guide). If I remember correctly, this driver works, however you have to manually point it in device manager (ignore prompt about being incompatible).
You could also try drivers available in Flashtool - in Devices -> Check Driver menu.

can't get Android WinUSB driver to install. Any help?

Did you try to manually select driver for fastboot device? You have to choose from all drivers, not using automated search. Windows will complain it's incompatible, but it should work.

[Q]Xperia Miro not showing up in adb devices !! Need help

Hello all,
I have installed android sdk, google usb drivers etc. I am using windows Xp. My phone is upto date as per the Sony PC companion installed in windows. When I try to connect my phone in usb debugging mode to adb, its not showing up. when I give adb devices it doesn't list any devices.
when I give adb shell, it says device not found. I tried all methods like kill-server, start-server and killing adb.exe etc. after I went thru the existing threads in this forum. Nothing works !!
And the interesting thing that I could not figure out is about the device manager. After I try all methods it says drivers not installed. I try to install google usb drivers as well by browsing the folder in my android sdk . It was displaying like 'nothing found to install'
Any ideas please ??
One update.
Google usb drivers were not being installed correctly. When I update driver and browse to the Android SDK folder where the Google USB drivers present (My case .... Android SDK-> Extras-> Google -> usb_driver) it says 'nothing to update'
Then I edited android_winusb.inf file there and included my device ID (as showing up in Device manager). And it installed the drivers.
Then I opened adb again. And gave 'adb devices' and finally I could see my device listed !!!!
But still one major problem exists. That the device is getting disconnected continuously from adb and each time I would have to restart the adb and this makes it useless....
Not able to figure out why ...
Try using this: adbdriver . c o m
If it does not work try flashtool's drivers

Xperia Z5 fastboot driver not installing

Hi,
I have a rooted Xperia Z5 and I would like to update my firmware to 32.2.A.0.305.
I used to do firmware updates many times before using flashtool on my windows 7 machine.
Recently I switched to windows 10 and now need to reinstall the fastboot driver.
I downloaded the driver from sonymobile webstie:
http://developer.sonymobile.com/downloads/drivers/fastboot-driver/
Unzipped the file, and got a directory with the "android_winusb.inf" file.
Booted the phone in "bootloader" mode via the TWRP recovery (LED on phone is blue).
The regular method of power down, volume up+connect to USB did not work. The LED was blue for a second and then turned off.
When in "bootloader/fastboot" mode, opened the windows "device manager" and found the problematic S1 device.
Right click on it, update driver, browse my computer, pointed to the directory where the ".inf" file is located.
Windows "makes sounds" as if it is installing the driver, but then gives an error:
"Windows found a driver software for your device but encountered an error while attempting to install it"
"Android ADB interface"
"The system cannot find the flie specified"
I have no idea what the problem is.
A few posts suggested that this might be a driver-signing problem with windows 10.
They suggested removing the "driver-signing" option and try. Did not work.
I also tried this with a virtual machine Windows 7 that I have installed, and got the same error, so I'm not sure it is a windows version problem.
I read in one place that this is an error with the location of the file and that it should be located under the "C:\Windows\WinSxS" directory.
Tried that as well, and no luck.
Does someone have any idea what the problem is?
Alernatively, if someone can explain or point me to a post of how to use fastboot and flashtool with linux,
that can also help.
Thank you.

driver signature verification
1. Goto START (windows icon);
2. Keep pressing SHIFT, klick POWER and RESTART
(shift is pressed all the time along);
3. Choose Troubleshoot > Advanced options > Startup Settings and click the Restart button.
When your computer restarts you'll see a list of options.
4. Press F7 on your keyboard to select Disable driver signature enforcement.
Your computer will now restart and you’ll be able to install unsigned drivers.
This is firt to do, but didnt quite get it if you tried this allready. Greetings
Have the same problem. Disabled driver signature enforcement. Did not help
Are you sure it's disabled? Some pc's don't have the option to disable the driver signature enforcement. If that's the case you need to enter the bios settings and look for the tk keys and delete them, then restart your pc and you can install the fastboot driver.
Hope this helps
Had the same issue on my new setup.

Disable driver signature enforcment then install flashtool drivers and select your phone drivers and fastboot drivers, it will ask you are you sure to install press yes and then in folder x10flasher you have fastboot and open cmd in that folder and just use fastboot. Cheers

"error: no device/emulator found" in fastboot

As the title says.
I'm trying to unlock the bootloader on my XZs so I can root it.
My device is listed normally when turned on w/ the command window, but in fastboot mode it disappears and when I try a command, an error comes up saying ""error: no device/emulator found". (see attached image)
As far as I'm concerned, I have all the necessary drivers, I've tried on another PC, the result is always the same.
And when I try to change the drivers (Via Device Manager>Update Driver>Browse My Computer...>Let me pick...>Have Disk...)
I get yet another error saying "The folder you specified doesn't contain a compatible software driver for your device..."
Can someone please give me a solution. This has been asked before on XDA by someone else (that thread has no replies). It seems it's always us little guys with actual problems which need solving who get little to no help at all here.
Reinstall driver again.
It doesn't work. The problem is I want to install the Google USB drivers for my Xperia phone but Windows 10 will not let me and driver signing seems to be impossible to disable (currently typing this on my laptop while it's in test mode).
1. Turn off your phone. Boot in to fastboot mode and plug the cable. After your heard the sound from the computer for new device found. Go to device manager look to usb S1 device. Reinstall driver by manual choose (do not search) from the menu with the name is Android Google. When prompt for install. Choose install anyway. After successful install driver, please check status from flashtool to make sure your device show connected in fastboot.
2. Change the usb port. Sometimes you get problem with usb port 2.0 and 3.0
Hope you can fix it asap.
Nothing by the name of 'Android Google' appears in the menu when selecting new drivers.
I clicked on 'S1boot Fastboot' under 'other devices' in Device Manager and clicked on update driver
>Browse Computer
>Let me pick
- and then there's something similar called 'Android Device' but no 'Android Google' so I click on that
- then I get three options:
Android ADB Interface Version 11.0.0.0
Android Bootloader Interface Version 11.0.0.0
Android Composite ADB Interface Version 11.0.0.0
None of them worked when I tried.
I think the solution is to have the phone on, with USB debugging enabled, connect via USB to PC, test your adb devices again, if all good, go ahead and
Rich (BB code):
adb reboot fastboot
This is because some phones use Fastbootd (notice the d..).

bootloader is wiped|

hello, i am in a bootloop with my oneplus 6. wiped everything.
since then i tried using the msmdownload tool, but it's not recognizing the phone.
in the device manager the phone is currently being recognized under "kedacom usb device" as android bootloader interface. I tried doing an update to the drive and installing a quallcom drive, but always get an error message "The folder you specified doesn't contain a compatible software driver for your device. if the folder contains a driver, make sure it is designed to work with your computer". i downloaded a few windows program to force installation with no success. tried signing the .inf file of quallcom driver - same errorwhen i try again. when i write in cmd 'fastboot oem unlock' - it says that the device is already unlocked. when i try the command 'fastboot twrp.img' or fastboot boot it also fails. i even downloaded tool-all-in-one - doesn't help. when im making an uninstall of the android bootloader interface, after connecting the phone again - it automatically installs this driver again, even though i marked in the settings not to do that. all i get is a bootloader screen, nothing else.
p.s. new here so sorry if the thread is in the wrong place or something.

Cannot recognise device in fastboot

Win10, in fastboot mode the device cannot be found, but it can be found in adb. I installed drivers from Sony's website. In fastboot mode the device manager shows under 'other', in adb it is normal and shows 'Sony sa0116 ADB interface driver'. As far as I know the driver is the same for adb and fastboot...my Pixel is recognised with no problem, only this Sony...anyone knows how to get it recognised in fastboot mode?
Sorted the driver issue... didn't install it properly...
Go to Windows device manager look for one called x-boot or android (your xperia) and open the driver details.
Klick update driver and next choose look for software on computer. Next window gives you the option to pick one of common devices. Install the sony driver for adb interface.
Could give a zip of it if needed.
After the manual driver update it should recognize your phone immediately - if you have checked the "fastboot devices" prompt before just repeat that (no reboot or reconnection necessary)
Win 10 seems to have problems. I downgraded to win 7 all sorted.
I'm having the same issue with my Xperia X compact. Windows 10 says it's installed best driver for my device but in device manager theres a warning next to the driver and device is not recognised under ADB devices. I remember it being simple the last time I did it under windows 7. Is there an alternative method for flashing Twrp recovery other than ABD?
Thanks
Dave

unfortunatly, adb is the only way to install twrp.
the drivers (i attached) [from Sony by the way] need to be installed.
You need to install this driver/ file : android_winusb.inf
then boot your phone to fastboot (volume + [up] only) or with adb (adb reboot fastboot) and windows should detect "a new device" which (normaly) is called "android" with exclamation mark.
Tap "update driver"
Search on PC
select from list
ADB interface
Samsung Android ADB Interface is the driver you need to select for windows to detect the phone
And then theoretically it should work.
If that doesn't work, look if a USB port (either PC/Phone/Cable) is broken/damaged etc.
