Fastboot issue Moto G8 - Moto G8 (Moto G Fast) Questions & Answers

Hey there,
so fastboot does not recognize my phone in bootloader mode.
USB Debugging is enabled.
- ADB Commands work
- Fastbootd Mode and Fastbootd Commands work (adb reboot fastboot)
However in Bootloader Mode it just does not show up. Either under Windows or Linux (No Device Manager, No LSUSB, Nothing)
Drivers are Installed.
- I have an AMD Processor and i am aware of the issues. I tried the USB controller fix.bat without any changes.
- I have disabled Driver Signature in Windows 10, still nothing
Please help :/

device not found

adb devices returns no listed devices,
One_X_All-In-One_Kit says device not found.
Tested with different drivers (HTC drivers from One_X_All-In-One_Kit,and Universal_Naked_Driver_0.72), phone is detected by Windows, in bootloader it says fastboot usb, but I can't do sh*t And it used to work just fine a month ago.
Tested on 2 different computers with different USB cables... (Win 7 and 8 run as admin).
One strange thing is that I remember updating TWRP to 2.6.0.0 and now it's 2.4.something. What happened, what can I do?
Just want to update boot.img so I can install CM10.2, currently on CM10.1.
No ideas?
I can connect adb over WiFi, but ofcourse it says offline.
USB debugging ticked?

Adb doesn't work in the bootloader. Only fastboot commands

Yes, I did this a few times before, I know how to do it. But now, there is no way to flash boot.img from PC.
I reboot phone in to Bootloader, connect it to PC (phone says fastboot USB), I can see ADB device in device manager, if I 'adb device' in Command Prompt there are none (except when I connect it with WiFi adb).

adb does not work in bootloader...
of that doesnt help, try another USB port... I know this sounds ridiculous but trust me, it helped me once before.
Well, i managed to get my phone be detected in adb and fastboot, by manually installing Nexus adb drivers (have a disk option).
Drivers that used to work- HTC drivers, won't do anymore. Don't know why.

Unable to get xA2 in fastboot mode

Hi there,
strugggling to get the xa2 into fastboot mode so I can flash a new boot.img and root. I've enabled OEM unlocking and installed the USB drivers. the command 'adb reboot fastboot' doesn't work, just reboots the phone. adb over usb works fine. The official method to get into fastboot 'plug in USB whilst holding vol up/down' also doesnt allow me to get itno fastboot mode, phone just stays blank with a notification LED. I use 'fastboot devices' to see it if it connected. I've tried this on 2 PCs now to no avail
I'm thinking maybe the fastboot drivers are wrong?
Does anyone have any other suggestions or help?
Thanks

Hi
Install "5 seconds adb drivers"
Connect the turned off phone to PC via USB just pressing volume down button (no power) and keep pressing it until you see the LED turning green or blue.
Here u have! :highfive:

Hi thanks for getting back to me,
I assume you meant the '15 second installer', which I just did just install successfully. I am still unable to see the device with 'fastboot devices' command.
Other info: I have factory reset the phone, made sure oem unlock is checked, tried the same process on another computer. I can get adb mode to work fine, but the command 'adb reboot fastboot' just reboots the phone as usual

That is the correct behaviour.
Blue LED = Fastboot mode
Green LED = Flash mode (for reflashing stock firmware with XperiFirm in case EVERYTHING is broken)
Install these drivers:
https://adb.clockworkmod.com/
When in Fastboot mode, go to device manager, there is an Android device in there (may also be called MTP device).
In the device manager, install a new driver for that and use the ADB driver from C:\Program Files (x86)\ClockworkMod\Universal ADB Driver
Windows will tell you that it's the wrong driver. Install it anyway and Fastboot will recognize your XA2 now.

If it won't work, after that just go to devices and printers and delete Xperia XA2. It will work.
Else, after installing 15 seconds, inside device manager, update the driver of your phone (or mtp device), select local, then Android device, then fastboot. Disconnect the phone and reconnect as before (volume down)
Fastboot is VOL. UP (on this device)! (Not vol. down)
So basically turn off the device, hold Vol. UP and simply connect to USB, hold Vol. UP until LED is steady blue and you are set.
Note: VOLUME UP activates fastboot and VOLUME DOWN enables flashmode and/or recovery mode
Similar trouble here.
1. VOL UP + plug in USB: Blue led blinks once, then phone shows it's charging (turned off)
2. adb reboot bootloader: Phone just turns off

I had the same issue with my XA2.
The solution (at least for me) was: different USB cable and different USB-port. As it turns out, my cable was somehow worn out (though data transfer and charging was working quite well). Going into fastboot, the blue led lit very short time and then the phone restarted. Furthermore on my PC it somehow only worked on the one USB port and not the other (both USB 3.0).
--> Maybe trying the most obvious might help also some of you

Did solve this by connecting to different PC. No cable/port/hub change did help. Looks like there was some trouble with drivers (though the same PC fastboots Z3 Tablet Compact perfectly).

I'm also having the same issue with my Xperia XA2 Ultra. (boy that's a mouthful)
Phone model is H3223.
Host OS is Windows 10 Pro v. 2004.
Using latest Android SDK tools (i.e. ADB and Fastboot platform tools): platform-tools_r30.0.5-windows. Got it directly from Android site.
I think I had a previous driver for Android already installed or somehow Windows got it. ADB worked, Fastboot didn't. Read online about someone on this forum getting it to work by using XZ2 driver from Sony as they evidently don't have a published driver for this device. The person who posted this solution had reported problems with this driver recently. I tried it anyway.... ADB commands work and my phone shows up when listing devices. Reboot into fastboot mode and the only thing my phone does is show a blue light indicator... no splash screen or logo. To me this means it's starting fastboot but my driver isn't working with it to recognize it as any commands for fastboot return nothing or fail. It doesn't show up under fastboot devices command.
Does anyone have a clue as to what to do?

I have the exact same problem, have not managed to find a solution trying with 3(!) different laptops and 2 different cables. No idea what could go wrong. I checked the device and it says that unlocking is okay. Really frustrating.
Edit: I actually found a way! Once you manage to enter the fastboot mode (light is permanently blue) go to the device manager in windows, click on the unknown android device, and install custom drivers (either by selecting from the list or by picking the universal adb driers from a local folder). These custom drivers should be adb drivers. Once they are installed, fastboot should work.
I had the same problems with my device XA2 H3113 and Win10.
My solution: Try it with Ubuntu. Just grab an 8GB usbstick, install Ubuntu via usb-installer, boot ubuntu and open a terminal
sudo apt update
sudo apt install adb fastboot

ADB don't work in Fastboot mode.

I am trying to root my Redmi Note 8. When the phone is on, adb works perfectly and recognise the device. I can even reboot device when the phone is unlocked. But once I go into Fastboot/Recovery mode then ADB fails to find the device and no commands work(.To the best of my knowledge, I have all the necessary drivers. I have tried multiple USB slots, multiple computers (Windows 7 sp1 and Windows 10 latest update), and have searched all around the internet and various forums on XDA for an answer. I've tried manually updating the USB drivers through device manager, installed universal usb driver, but that did nothing. What I don't understand is that how ADB works when the device is on but don't work when it's in Recovery/Fastboot mode. I would have post images to clear things but the site is not letting me to post images
tldr: adb recognize phone when it's on but Adb don't work in fastboot/recovery mode
Thanks in advance for any help, I've tried everything I can think of.
Replace adb by fastboot in fastboot mode
ex instead of
adb reboot
type
fastboot reboot
You've to use the fastboot command instead of adb. Please note that fastboot doesn't have all adb features, e.g. install, shell, etc

example:
in adb-> adb devices
in fastboot-> fastboot devices

Can't unlock bootloader - fastboot issue

Hello,
I am trying to unlock my bootloader but I my computer (Windows 10) does not recognize fastboot.
When I connect to fastboot (holding volume up button + connecting my phone by USB when it's off, or using the adb reboot fastboot command), the computer does not recognize the phone. I then tried installing drivers (both from Google and Sony) by going into device manager but Windows just doesn't install the drivers.
I then saw this on Sony's website:
Fastboot driver - Sony Developer World
developer.sony.com
So I download the file and pasted it instead of the same file (android_winusb.inf) in the Google driver folder, and it somewhat worked, but Windows said something like unable to find drivers for ADB.
I also tried to install in Windows test mode but to no avail.
No matter what I tried, entering the command fastboot devices in fastboot mode does not give me any output (not even "waiting for device").
What am I doing wrong?
Thank you!

Did you already disable driver signing? Pretty sure you have to do that with Win 10. I would disable driver signing, and then use " 15 second adb installer" from XDA. Always has worked for me...
