trouble with bootloader unlock

Hello everyone, I'm trying to unlock my bootloader but I have hit a roadblock and cannot seem to find anything that helps.
The part where i am stuck at is that when i enter "fastboot.exe -i 0x0fce getvar version" all i get is "waiting for device" infinitely.
I know the phone is in fastboot mode because the blue light is on
It seems my pc isn't recognizing my phone when it's in fastboot mode. I can see my phone in windows device manager as "S1 boot fastboot" but when i try to update the drivers manually using the drivers provided by sony, i just get an update failed screen.
any help would be much appreciated, i'm sure it's something dumb that i did, but i just can't figure out what.

try using different usb cable/ different port.

Had same problem....some driver was missing
Sent from my C5503 using xda app-developers app

I've finally gotten flash tool to work, however now it gives me an error saying that my device cannot be officially unlocked,
EDIT: i'm pretty sure i've unlocked the bootloader now, as flashtool had me enter an unlock code and my device has had all of its data reset.
however my issues continue as now flashtool utterly refuses to pick up my device. I have re-installed all drivers, flashtool, etc but still nothing.

sometimes it may have conflicts when flashtool and other tools use their own instance of adb or fastboot. I think the best thing to do now is reinstalling regular drivers normally. don't forget to enable usb debugging...
this may be useful :
Code:
[I]ADB_PATH[/I]\adb kill-server
exit
create a text file, paste this code then save it as ADB - Kill.cmd

[Q] Bootloader Troubles

Last night I was on my nexus before I would go to bed. I opened the franco kernel app and then noticed that r6 was available for download. I downloaded and flashed it and was about to go to sleep when I noticed the notification light that my phone was charging. I thought it was neat then tried to get some sleep, but my promised sleep did not come quick. After a good chunk of time had passed, I thought that my lack of sleep was caused by the green light that was barely noticable. I searched and searched in the app to try and find an option to disable the LED, but could not. I then decided that the best way to get rid of the light, would be to flash the older r5 kernel so I wouldn't have to see the light anymore. I hit flash and my phone rebooted and then brought me to the bootloader. I attempted to reboot but I could not. I've tried using adb and nexus root toolkit to get my device to work again, but they can't seem to find it without the correct drivers. I installed Motorola device manager, nothing. I tried to follow the instructions in the toolkit to get the correct drivers installed but I can't continue with the need to enable debugging, which I cannot do from being stuck at the bootloader.
Under bootloader logs, I have the following messages:
Invalid boot image size!
failed to validate boot image
Fastboot Reason: Fall-through from normal boot mode
Any help would be greatly appreciated.

USB debugging is an android setting. It can only be used when android is running. If you had USB debugging on, it would make absolutely no difference in recovery or bootloader so don't let that step stop you.
From the logs, it sounds like your kernel download is corrupt or didn't flash properly. I had a similar message when I flashed a partially downloaded recovery image today.
Just fastboot flash a complete boot image

I tried that last night by launching adb and doing 'adb devices' but my device is unrecognized and I am unsure of how to go about fixing that.

Tried what exactly? Adb and fastboot are two different things. Adb works in android or recovery only. Fastboot works in boot loader only. Boot to boot loader and do "fastboot devices"

Ah that was my mistake. But the fastboot devices command just returns a new line for a new command to be entered in

That probably means there is a blank line between them - showing that no device is found. Unlike Adb it just gives a blank line instead of "no devices".
Probably means a driver issue or cable issue. Try different USB ports / cables if you can. Check to see if there are any yellow triangles in device manager too.
I'm new to this phone so I don't know where the drivers are if you need them. If I ever find them, I'll port my nexus 5 Adb and fastboot thread over here. Unfortunately i use Linux at home so I don't really have a driver issue.

Oh, so if I were to use Linux I wouldn't have to deal with missing drivers? I'm assuming that's the issue since no matter which port I use, 'Connect USB Data Cable' doesn't change

I can't say for sure. In Linux you may need to add UDEV rules. I didn't though. My bootloader is just recognised.
Please do check your device manager though.
I'm sorry i can't help more right now. I'm going to bed.

Okay, thank you! I'll reply if I encounter any other errors!

xz2, can't acces bootloader

I tried the guidelines to boot into bootloader, I'm using xz2 non premium/compact, I press vol- a while and connect USB cable to PC but I never boot into bootloader, even when I try using adb command "adb reboot bootloader" it just reboot into normal system, what can I be doing wrong?
Also I have no update, I'm still on 8.0.0,I keep checking and it says you're using latest Android version, how come?

Do you Know of any tricks to boot fastboot/bootloader,I want to unlock it, the current methods not working,I get a black screen and green/blue notification light (-vol and connecting USB cable from pc to phone) when I input fastboot commands, it says "waiting for available devices" and fastboot devices says no device connected, but adb devices (when in normal boot) recognises my device

Then the fastboot driver doesn't work correctly, is not correctly installed or the wrong got installed, while the adb driver is fine

similar problem: fastboot issues
I apparently don't have standing to post my own thread, so I'm replying to this one which is similar. My apologies.
I've downloaded adb and fastboot on my win 7 machine to unlock my bootloader on the way to rooting my xz2 compact. Fastboot will not recognize the phone. Adb does recognize it, and fastboot recognizes my Moto X DE, so both utilities seem to be working fine. Additionally, using 'adb reboot bootloader' cycles through a green, red and then a faint blue led, the latter which just stays there continuously with a black screen.
I've spent quite a bit of time on this looking for a solution, so I'm turning to you all for help.

The bootloader is just black with blue led.
Download mode is just black with green led
Recovery is just recovery with red led
System is just system with all led Colorado or none

Sorry, if didn't communicate this well. I need to unlock the bootloader using the fastboot command, yet fastboot overtly doesn't recogize the device. (no recovery screen menu is a separate problem). so,
'fastboot oem unlock' returns
'< waiting for any device >'
even though the phone is recognized by adb and other phones are recognized by fastboot.
How do I get the phone to be recognized by fastboot is the main issue.

Fast Boot

I received my new sony 1 ii and have checked and the bootloader can be unlocked and the phone can be rooted. I thought I was away to the races but I'm mystified. I can't get the phone to boot into fast boot.
I appears I have the drivers in place and the phone is recognized by the computer but no luck with fast boot.
I have searched and can't seem to find out why this is. I suspect some kind of driver issue with win10 but when I connect to the computer with the phone off and hold the up-volume nothing happens. I have also tried to boot into recovery mode and that does not work as well. Any help would be appreciated.

On Sony devices you need to power off and hold volume up and plug in the USB cable. That should leave the blue LED to indicate fastboot mode. I'm not 100% sure since it's been a while since I've messed around with Sony devices

Thanks for the input. I have done that and am still unable to action ADB - It is a little confusing since the phone only shows the blue light and nothing else.
If I normally boot the phone it will register as an ADB device. I also find it strange that it will not boot into recovery. The android icon flashes but when you release it boots to safe mode. I assume it is a driver issue but it is not revealing its self to me . Cheers

The blue light is fastboot mode. There is no ui interface in fastboot for sony devices. Just a blue light and black screen.

Same person but had to change user name -- more on the issue
I managed to unlock the boot loader and it seems that at every step for rooting I am running into curve balls. Windows was not working for me so I managed to unlock the bootloader with Linux and going on to the next step I had to go back to windows to find a current factory ROM.
The next issue: going back to the "how to" I am unable to located boot.xxxxx.sin in the factory ROM and the closest I could find is boot_x-Flash-ALL-2389.sin and that doesn't work.
In the boot directory all files are bootloader_X_44 and a combination of zip and sin files
Can anyone steer me through the muddy waters
The factory rom was downloaded through XperiaFirm application

May I know how did you unlock the bootloader? Did you use xperia 1 as your device in https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/#unlock-code?
I have already installed usb drivers and have the platform tools. But everytime I boot my device to fastboot, whether using "adb reboot bootloader" or power button + volume up, screen only shows black (led is solid blue). I did left it for a couple of minutes, nothing happened.

I unlocked my bootloader after obtaining the unlock code from sony developers I used adb/fastboot commands in linux mint. Pretty straight forward but the next step for rooting is giving me issues. Just select xperia 1 and the imei number will identify your phone -- cheers

Yes I followed those. But may I know how long it took you to finish the unlocking?
Install ADB/SDK drivers
Download platform tools
Plug the device
Make sure adb can see my device
Use adb reboot bootloader command
Device booted to fastboot mode
Execute the command with the unlock code
...stucked here
If I miss something. Please do let me know

I assume you are using windows and I must say I gave up trying to get win10 to work and I was stuck at the same place you are. I then switched to linux and it went a lot smoother and I didn't need all those tools as laid out in the description.
In linux you must use the phone to go into fastboot mode if you boot from computer it actually boots to a visible screen on the phone and I didn't have connection that would take the command line commands. Linux is very good because if you are missing something it will give you a link or a command line input when you execute the ADB or Fastboot command.
I have run a windows/linux dual boot desktop for a while now and I'm no expert but coming from the era of command line I can muddle through. Sorry if I can't give you more info on windows but win10 is such a pain and I find that with a lot of things linux works better. If I didn't need adobe acrobat I would not even bother with windows.
cheers

Yes I am using w10. Will try linux later. I have searched everywhere and stucked at the same step. Thank you.

I have managed to unlock the bootloader and root the phone. But problem is. I can't write on the root folder.

More to this I think I might have located the boot file boot_X-flash-all-2396.sin but using magisk it returns no boot image found. I see the guide says use the canary built but that seems to have been shut down, so at an impasse here and am still reaching out for help - damn op phone were never this funky
I might as well put this one out there then -- Is there anyway to flash a op 8 pro in2025 to dual sim - it's the cause of this painful trip

I was reverting my phone to unroot and locked bootloader. And it is saying that "Your Device is corrupt. It can't be trusted and will not boot" loop.
I tried flashing it using the new flasher. But after flashing, it will do SONY boot loop. If I connect it to a charger it goes back to "Your Device is corrupt. It can't be trusted and will not boot" loop.
I can't use Sony Companion since it is saying that my battery is low, and I can't charge the phone since it will just continue looping.
Do you know/have any recovery.img?
Edt: Fixed my phone. Relocked the bootloader

Any chance you could post the steps to relock successfully? I presume using the fastboot commands etc though did you then just re run the command to relock the bootloader? Many thanks

First, you need your bootloader to be unlocked. It's pretty easy if you have that done already.
You'll need ADB and Fastboot. It can be tricky to get the right drivers. The driver used when your phone is connected in normal mode is not the same when connected in fastboot mode, in my experience anyway. You'll want the 15sec ADB driver and you'll need to update the driver when it is in fastboot mode.
Next, get the correct twrp img and put it in the ADB folder(you'll need a different one based on flashing a pie rom or a q rom). You may want to rename it so it's easier to type in fastboot.
To enter fastboot mode, hold volume up and plug in the usb cable. The LED should light up blue.
Open a command prompt and navigate to wherever you've installed ADB(mine is on C:\ so it's really easy).
Type "fastboot devices" to double check if the driver is installed and your phone is connected in fastboot mode.
------It should show something like: BH9090808E fastboot
Then type "fastboot flash recovery twrp.img" - or whatever you've named the file. It will take less than a few seconds.
Then type "fastboot reboot" and let your phone reboot.
Done

Thanks a lot for the reply!
I've been experiencing the exact issues you described. I'm having issues unlocking the Bootloader. "Fastboot.exe devices" does not show anything, the phone is with a blue led on and a balck screen and when I look in Device Manager there's an "Other" Android device with an "!".
Could you please share the drivers you mentioned? Because I really went through
everything and none was accepted. Also the 15 Seconds ADB Drivers did not help.
Thanks!

My apologies. It's been so long since I've started from scratch, I must've gotten the drivers mixed up. The 15sec ADB is for the phone connected in normal mode.
I'm pretty sure this one is the fastboot one:
