Hello
Posted this over in Pauls MoDaCo forum as well but not had any replies yet so thought it best to try here as well.
I've bricked my Desire, phone loads up but the sim and sd card aren't recognised (though I can still use wi fi).
When connecting the phone to my PC (tried windows 7 and XP) the drivers fail to install and I get various faults like the device being recognised as android 1.0 usb to a Qualcomm device.
The phone is still rooted (I can install rooted apps from the market) however after following various unbricking guides I always get stuck at stage 2 (i.e. enable sd card), if the PC won't recognise the device how can i run the 'fastboot oem enableqxdm 0' command?
I've also tried running fastboot using a terminal app on the phone but it doesn't recognise fastboot, should i be in a specific directory on the phone when running this command?
Any help greatly appreciated.
Cheers
Have you tried using a different jab port? I had to use one at the back of my pc front ports wouldn't install drivers properly.

You need to follow the guide on modaco for unbricking your device. You have the usb brick, and it can easilly be fixed.
Follow the steps religiously and you will be up n running in no time again.
I've followed the guide lots of time, it's not that long winded so it shouldn't be to hard to follow.
I get stuck on step two, using the fastboot command.
My PC and also tried laptop (Win XP and 7), different USB ports (front and back) but each time it attempts to load drivers and I end up with it either being recognised as an Android 1.0, Android Bootloader Interface or a Qualcomm device. I then run fastboot, and get the device not recognised error.
I've now tried to connect my phone to a windows Xp and 7 PC and a laptop, a Linux laptop and tried using the Tiny Linux root guide to see if that would work, but each time the PC/laptop fails to recognise the phone so can't get into recovery or run the fastboot command.

You don't need to get into recovery for this.
You have sdk installed, so boot your phone by pressing power while holding down the volume down button.
Use a command prompt on your pc and cd to the tools directory in the sdk. If the sdk is saved to the root of your C: drive on the pc you would type
Code:
cd C:\android-sdk-windows\tools
When in there type
Code:
fastboot oem enableqxdm 0
This will re-enable your sd card and allow you to continue.
That doesnt work, just stops on the waiting for device line and doesnt continue.
Also using the cmd 'adb devices' shows nothing so I'm guessing my phone isn't recognised on my PC. At the moment it's in fastboot usb (on phone) and in devices on the PC I've got Android Bootloader Interface with the yellow problem sign against it.
thanks for your help, it's appreciated, tried a few forums but no one is that interested in helping.

It definitely sounds like the old usb brick problem, so that's a good thing! When you tried the commands were you booted into fastboot? When you connect the phone to the computer does the phone display change from saying fastboot to fastboot usb? I think thats what it should say, can't remember to be honest!
Have you tried another usb port, and a different cable too?
Edit: I'd also try rebooting the computer to ensure any running process etc are closed.
Got it fixed, final throw of the dice this morning I connected the phone to a Vista laptop and it was recognised straight away, so downloaded HTCSync then ADB tools on to the laptop and finally got the re enable command to work.
Jeez that took for ever, strange that Xp, Win7 and Linux PCs couldn't recognise the phone but Vista did.
Still got it sorted, thanks for the help.
No worries. Glad you got it sorted.
I have almost the same problem.
but with the legend.
SD is not recognized.
Can´t Call,
Can´t connect via USB.
Is there something I can do in the built in terminal in the ROM?
Trying to unlock bootloader on my pixel 2 XL. Using a windows 10 64-bit laptop, usb-c cable that came with the phone, latest drivers and up to date platform tools. Debugging enabled. OEM unlock enabled.
Phone is recognized in ADB just fine. "Adb devices" results in the the device being listed. "ADB reboot bootloader" reboots the phone into fastboot mode just fine. Once in fastboot mode, however, "fastboot devices" yields nothing.
Pulling my hair out here, and not much hair left to pull. I suspect I'm going to have to tinker with the computer's security settings to get the drivers to install correctly. Any thoughts?
I seem to remember the same thing happening when I got mine a couple days ago and unlocked the BL within a few hours of unboxing. I ended up doing the standard unlock followed by unlock critical commands anyway. Worked fine for me.

Try just turning the phone off and then entering fastboot via volume down and power button. THEN, plus in your phone. Do a 'fastboot devices' and see if it shows up now. In my experience, I got my phone...checked oem unlock and all that...booted into fastboot mode via hard method. And my phone is detected instantly. I did not install any drivers, update platform tools (mine is from like 2012), and even used a third-party USB-C cable. It works every time. Also, I am using the adb and fastboot executables from an older adb minimal set. Probably from like a year or so ago. I don't ever use the SDK ones really anymore.

I'd check and make sure your adb/fastboot is up to date, or do a reinstall just in case.
There are so many options for adb/fastboot and drivers. Where does one find "the latest," that everyone is speaking of?
Thanks for the suggestions but still not working. Even tried disabling driver signature verification at startup. I'm going to uninstall everything, factory reset the device and start over. Might also try a usb-c to usb-a cable. Any other thoughts?
Update: Nothing worked until I used a usb-c to usb-a cable, then it worked like a charm. Must be a Lenovo thing.

Latest ADB/fastboot: https://developer.android.com/studio/releases/platform-tools.html
Latest USB driver: https://developer.android.com/studio/run/win-usb.html
I had no luck except about once in 20 it'd work. Then swapped to a different USB-C port on my laptop, then it worked. FWIW, I tried USB-C to USB-C and USB-C --> USB-A (adapter) to USB-C and it didn't make a difference.

I did this and when in the bootloader screen, I am able to display fastboot devices, but when I go into recovery mode and try and flash something via ADB (the November patch since I am not pulling it OTA), it seems to start but it just sits at "Verifying update package" on the phone and "loading: 'taimen-ota-******.zip'" and never progresses. Almost like the PC and the phone are not talking properly?

Like others have stated, maybe try a USB-C to regular USB-A cable. I have only used that type of cable, but didn't realize that the actual cable that comes with the phone might be a problem. I never used it to test that theory though.

I don't know then. I haven't attempted the update yet to provide any feedback. However, others have reported this issue in the 'November OTA' thread. I would look there.

For anyone in the future, ensure the that Device Manager is showing the 'Android Composite ADB Interface' driver installed.
Then, just download the latest Platform Tools (from https://developer.android.com/studio/releases/platform-tools), and from inside that folder, open a Powershell prompt, and then 'adb reboot bootloader'. Once you are in the 'fastboot' mode, the 'fastboot devices' command works.
I had the same problem. I fixed it by plugging in my UBS-C to USB-A cable into a USB 3 port instead of a USB 2 port.
I am facing the same issue, its been almost 20 days. Tried everything but couldn't get it worked. So dropped the idea of rooting my px2L
My issue was I needed to replace the drivers for fastboot mode (ADB was fine). There are two drivers, one for each mode.

This works... Get the Google Driver.
I've been researching and trying to sort this out on my own for a while now. I've turned up nothing, so I figured I'd ask for some help. I'll try to provide as much information as possible here.
I was attempting to unlock and root my Razer Phone from my Windows PC. I plugged it in and had it recognized over ADB with no issue. I sent "adb reboot bootloader" to start things off. Once it was in download mode, I sent the "fastboot -i 0x1532 devices" command to make sure it was recognized. It wasn't. I checked devices manager, and sure enough, it was not picking up the Google driver that every other device I own works with. I attempted to update the driver manually by pointing it to the inf file. It gave me an error stating that the driver is not designed to work with 64-bit Windows. I found that odd, as this is the exact same driver that I've used with my other devices for this stuff. I plugged in my HTC 10, since that was nearby. It was recognized via fastboot like it always was. Same cable I was using with the Razer and everything.
I booted to Linux Mint on the same machine and tried the same stuff. It would pick up the Razer only in fastboot, but not ADB. In fastboot, I could detect it with "fastboot -i 0x1532 devices", and it showed up just fine. When I attempted to run "fastboot -i 0x1532 flashing unlock" it just gave me the fastboot command reference list. (I don't have a screenshot, but it looked like this, in case you're unsure what I am referring to.) I rebooted back to the system and double checked that I had checked "Enable OEM Unlock", and I had done that already. I double checked everything with my HTC 10, and again, it all works fine on the HTC 10. ADB and fastboot are both recognized correctly on Linux.
So armed with this information, I moved over to my Linux server. I used a different cable this time, and got a similar result. The Razer phone was recognized over ADB and I was able to get into fastboot. Once there, it was detected with the fastboot devices command. I attempted to run the unlock command, and again was presented with the fastboot reference list as before. Double checked with the HTC 10, and all was workign fine with that device.
Does anyone have any ideas, or is it possible that it's the Razer phone that's the problem? I may have access to a Mac laptop later on, and I could attempt this from there, but this is getting nuts. I don't think I've ever had this much trouble getting into a device before.
Yeah I had this as well, basically you may have the latest drivers but are missing the latest adb/Fastboot executables. Apparently they have changed a few commands in the newer one and that way of unlocking isn't in the old version. Just google for the adb/Fastboot package from the Google site, can remember the exact name but it was the first hit on Google. I just extracted the whole zip to a directory and used it right from there. The reason you are getting the help screen from Fastboot is cause for that version at least, your giving it an illegal command.
I got the same problem till I put my usb in a usb 2.0 in the back of the pc in a highlight usb port witch I read after on Asus Website that suppose to charge your phone if you turn off your pc so basically a always on usb. Also I managed to unlock and brick my device only with one cable I tried 4 cables none of them worked .so for you to keep In mind
Try different cables
Try usb 2.0
Try driver from twrp for razer phone thread that worked for me
Seems to be an ongoing issue for me on my main desktop. I grabbed my old development laptop out of the closet, booted it up, and I was able to get everything recognized and working. I tried doing some more work this morning on my desktop and noticed that I'm having driver issues elsewhere, so it seems to be an issue with this machine. I'm still not sure why the Linux installation on the same machine was exhibiting the same issue, though.
Hello,
I've been trying for the past several hours to unlock the bootloader of my Moto Z2 Play (model:XT1710-09) by following different tuturials but fastboot don't seem to detect my phone, no matter what i do.
Nothing happens when i type “fastboot devices” in the command window.
I've noticed that my phone appear in the device manager in "other devices" as "Fastboot albus S" when it is in bootloader mode, which doesn't seems normal.
Edit: Some additional info: -i am on windows 10 pro
-ADB detect the phone whit no problem but Fastboot doesn't
-when connected with usb debugging enabled, windows detect it as "ADB interface" (which seems normal) and use "C:\\WINDOWS\system32\DRIVERS\winusb.sys" as driver (which seems less normal to me, i may be wrong)
-i tried installing Motorola specific drivers but i only found MotorolaDeviceManager, which doesn't seem to do anything, and no way to download the drivers manually
Edit 2: I still don't know why i can't get it to work on windows but i just managed to do it using a linux bootable usb, my device is unlocked \o/
If anyone know why fastboot doesn't wok on my windows and how to get it to work, i'm still interested
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
