So I have literally tried every single method I have come across and I have seen a few people having the same issue i have.. adb devices see's my phone adb reboot bootloader works and puts me into fastboot mode, how ever thats where everything stops working.. this is a fresh install of windows, fresh driver installs and everything is up to date adb/fastboot wise..
as soon as i type fastboot oem unlock it says waiting for any device and stops never finding the phone..
any help solving this issue would be great.. and the one click method wont work on my phone either
I was dying on this last night but finally figured it out. ADB worked fine, but Fastboot said "waiting for device". I would suggest downloading USBDview if you don't already have it.
Boot your phone into Fastboot and connect to computer.
Check USBDeview for driver that doesn't have a green light next to it.
Open Device Manager and find that device
Right click and update driver and Let me Pick from list
Look for Fastboot and install it
Two seconds later, your bootloader will be unlocked.

When you say "Look for Fastboot" where is this driver that I can choose?

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
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!

Hi,
I looked all over the place but could not find a way to unlock the bootloader of the latest version of my device. Currently running Android 6.0 H81120p and rooting this version as well!

did you click on screen when you gave the command to go into fastboot it shows some sort of numbers and leters and asks you if you want to allow phone .??/ did you
Yes I did allow the computer to have access to the phone, when i typed the command to reboot to bootloader it did, but then when i type the command to fastboot oem unlock it gets stuck on waiting for any device. I tried doing it again just to check, after i get to bootloader, i typed adb devices it doesn't show any device thats connected

I checked the oem unlock, and the USB debugging thing is checked as well. Developers Options is on but same issue. I installed the latest USB drivers, installed Google USB drivers. I went to device Manger and I can't see that my device is even connected!

Use Linux dude, also try different cables. My stock g4 came with a bad cable that only charged.
I've had exactly the same problem as hammy88. Is what is referred to as "fastboot mode" the same as download mode? I know it's relatively easy to get into download mode. But "adb reboot bootloader" doesn't work for me.
Fastboot mode ≠ Download mode
If you did tick "Enable OEM unlock" , and adb reboot bootloader doesn't work, then I guess is BL is locked now.
I tried the method , i found that Android Bootloader does not have a green light, so i went to device manager to try to update the driver but it wasn't even there, clicked on view to show the hidden items or whatever then found android device, when i clicked update the driver i could not find the Google fastboot thing to update it with, all i got was either LG usb or ADB interface even thoough i downloader google fastboot usb drivers few days ago

Brother, be calm. Find the fastboot drivers. And update.
You will figure it out. Just do it.
Hi guys,
I've got a real head-scratcher over here. I followed every guide to a T, but I can't get my computer to detect my device in fastboot.
I installed the Xperia companion. I tried to manually install the Google USB drivers, and the sony OEM drivers. Still, no matter what, when I enter, what is supposedly fastboot, it never shows up. When the phone is on ADB devices shows it just fine. I am at a total loss!
To enter fastboot, I am shutting down the phone, pressing the volume up button, and plugging it in, then I get a black screen and a blue LED, which supposedly is correct? I've personally never seen anything like this before. Device manager does detect it as an unknown Android device, however, if I try to apply any drivers to it Windows simply informs me I already have the latest ones installed.
Thanks
SOLUTION: It was a driver issue after all. Windows 10 would not detect any drivers, nor let me install any drivers manually from files, however, it did let me select built-in drivers from my computer. YMMV, but If you are running into this issue try this:
1) Put your phone into bootloader mode.
2) Open device manager.
3) Right-click the device called "Android" with the yellow question mark, and select "update driver."
4) Click the "Browse my computer" option.
5) Click "Let me pick."
Note: There are several categories here, I suggest you try them all: portable devices, android devices, and in my case, Samsung devices. In one of the categories, you will find Google listed as a manufacturer.
6) In one of the categories, you will find Google listed as a manufacturer (in my case it was under the "Samsung Devices" category).
7) Select Google and then select the newest fastboot driver listed (in my case it was dated 2016), and install that driver.
8) Go back to PowerShell and run "fastboot devices." With a little luck, it will work!
Previous steps:
Edit: I had the thought of trying
Code:
adb reboot fastboot
and that got me into fastbootd, and then my PC detected it, however, the phone did not accept the unlock command.
Code:
FAILED (remote: 'Unable to open fastboot HAL')
fastboot: error: Command failed
I rebooted into the bootloader from here, got the same black screen, blue LED as above, and my phone is still not detected by fastboot.
Make sure you open cmd window in fastboot folder...i hope this is help
Sony fastboot mode is different I think. It was odd to me but doesn't show anything on screen when I went to fastboot to flash US firmware

I live in Boston and got the the XQ-AT51 (despite the fact that B&H was originally selling the 52... so in a few months I'm going to have to flip this phone ), do I have to reflash a stock firmware before I can unlock the bootloader? I do have it from XperiFirm.
Edit: This was dumb of me as you can't flash anything onto the phone unless the bootloader is already unlocked.
Edit: I don't want to double post, but I managed to solve the problem, and added the solution to the OP.
THANK YOU VERY MUCH FOR THIS GUIDE. I was struggling for hours on end with the "Unable to open fastboot HAL" error message, but followed the steps outlined in your guide a little differently than you, since I'm on windows 7. I believe that the root cause of my issue was that I actually used the down volume button instead of the volume up, believing that it was weird for the screen to show nothing except for the blue notification LED.
Here is what I did just in case for people who might encounter the same issue in the future. Be warned though that I'm not an english native so the options won't be accurately translated but I'll try to do my best nonetheless.
1) Put your phone into bootloader mode (volume UP + power button, not down.) Don't be afraid if nothing shows up, it's actually normal
2) Open device manager
3) Right-click the device called "Android" with the yellow question mark, and select "update driver."
4)ISelect "Look for drivers on my computer (manual install option)
5)Select "Choose from a list of drivers installed on this computer"
6)Scroll down through the manufacturers and such until you find "sony sa0200"
7)Install it
Normally everything should be working fine with fastboot. What a relief
I have a similar problem, but my device manager does not show any android device from the bootloader. I've tried multiple cables and everything works fine in adb mode.
EDIT: Nevermind. It ended up being multiple bad cables. They all worked in ADB/booted but not in Fastboot/bootloader. Tried one more it it worked completely
I have same issue with my Poco X3 Pro, the device working fine and is recognized as ADB composite when i'm under MIUI, but when i launch the device in fastboot mode, the ADB composite disappear and a generic "android" device appear and i'm not able to install any drivers, no qualcomm, no xiami, no generic google usb, nothing.
Following the tips above, nothing work. I'm under windows 7.
Any tips?
Thx everyone for pointing me to the right direction. Flashing latest twrp was the final step. Recovery is back to now .
I've been searching all over the place...
Could anyone point me at a guide for newbs?
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:

If not, I'm sorry because that's all I have.
I nailed it eventually!
