Hi all, i wish to know why i cant root my asus zenfone go (z00vd) (cannot found the category in our site sry). I used some guides, all of them says the same process. Install adb driver, done. Fastboot mode your phone, done. Check with command line fastboot devices, done. Write "fastboot oem unlock" or "fastboot flashing unlock", the device says "unknown command". I allowed usb degub and oem unlock from inside the phone (installed fw 37). i tried several times, pls help me !! thanks so much.
few points. first of all disable usb debugging and revike all usb debugging authorizations. now connect phone to pc and enable the usb debugging. now on your device a message is must to appear something like authorize this computer or pc. tick that option and always authorize pc for usb debugging. enable oem unlocking in developer options..
second thing is special fastboot.exe.. the thread where you downloaded root files. there must be a special fastboot version. use the downloaded fastboot.exe to perform unlocking command

When I connect my HTC Desire through USB cable to my laptop, my laptop wait a while then pop a windows which says USB Device Not Recognised. My device just got the orange light lit up but there is no response other than that i.e. no menu pops up to choose "charge only, disk drive" whatsoever.
It worked just two days ago before I reflash a new ROM (RCMixHD 3.6.1).
During the flash, the SD card was not recognised too so I tried to get it work by using "fastboot oem enableqxdm 0" as instructed by one post named "USB brick/rickrolled/b0rked -> FIXED!" on MoDaCo.
But I did not flash the update.zip as required cos my problem was fixed before this step.
Can anyone help me fix this problem? Waiting online
USB debugging still enabled?
What result from either adb or fastboot?
Code:
fastboot devices
adb devices
FASTBOOT shows "FASTBOOT USB", Bootloader also gives me "HBOOT USB PLUG", I think the USB cable is fine.

I tried the two commands in cmd, I copy down what it gives me
E:\SDK\Tools> adb devices
List of devices attached
E:\SDK\Tools> fastboot devices
HT05HPL12963 fastboot
E:\SDK\Tools>
Ok so the fastboot result means you can connect to PC.
What happens if you connect your device whilst it's booted up with USB debugging enabled? Enable this prior to connecting in settings>applications>development.
Hi thanks for the help, I managed to unbrick the USB brick. But now even though I'm able to connect to my laptop, the adb devices still doesn't give me any device. In device manager, I got an "ADB" with yellow exclamation mark under “Other Devices”, just cannot get the right driver for it. Could it be due to the USB brick?
I have somehow installed the fastboot drivers for my Pixel C (although ADB still doesn't work), and have successfully (?) unlocked the bootloader.
If I try to flash either the newest bootloader in order to install the N Developer Preview or a TWRP image, I get the following message:
FAILED (command write failed (No such device or address))

I tried different USB ports but the result was the same. I found somewhere about fwtool, but in order to use that I have to be rooted (if I understood correctly).
Any other ideas?

I'm assuming that since you were able to "successfully" unlock the bootloader that you can do this to check and see if your PC still recognizes your device. So, while you have you're Pixel C in fastboot and have it connected to your PC, open a command prompt and type the words fastboot devices and see if it returns your device serial number. Normally the command prompt will show that message when your device is not properly connected with the correct drivers installed. Also, if you have the correct drivers installed your ADB should work if you have enabled USB Debugging in developer options.

Well, fastboot devices (and all fastboot commands) works. As for ADB it shows my device, but says unauthorized and never asks for my authorization.
But the thing is that I cannot flash anything.

Okay. If it will recognize fastboot commands let's start over from the beginning. Go to developer options and verify OEM Unlocking is checked and USB Debugging is checked. If you have the correct ADB drivers installed you will receive a pop-up message that says "This computers RSA key fingerprint is xxxxxxxxx. Check the box to always allow. Next, boot to the bootloader and type fastboot devices in a command prompt window. If it returns your device serial number then we are good to go.
Next, open a command prompt window and type fastboot flashing unlock. (may have to use fastboot OEM unlock) I've seen both work for some reason. If you are successful your Pixel will give you a message saying the bootloader is unlocked and OS verification is off. Once it's complete it will boot into the bootloader again. Once this happens, boot normally and hurry through the setup wizard so you can enable developer options and enable USB Debugging.
Now, once this is done boot to the bootloader and open another command prompt window and type fastboot devices to verify you are connected. If you are connected then you can fastboot flash the Android"N" bootloader and install the developer preview. Lemme know how you make out.

Thanks for the very descriptive post. The thing is that I have already done all that, with the exception of using ADB, the pop-up never appeared and my Pixel C appears as unauthorized in adb devices.
I know for a fact that the bootloader is unlocked, because everything got wiped afterwards, and I also get the message saying that the bootloader is unlocked in every boot.
The thing is I cannot flash neither the developer preview nor the TWRP image. I read somewhere about a similar thing some users had on Pixel C, but the solution was to either do something via TWRP or use fwtool that needs root. And I can do neither.
So that's why I started this topic to see if anyone can think of anything else.

On thing to try is to go into the settings Developer Options and "revoke USB debugging authorization". Connect to PC and you should then be asked to allow the "fingerprint". Hopefully that will fix it. I assume you've tried changing the connection type - charging, File transfer etc. If you are using W10 Pro then you may have driver issues. There are many posts on the net about that os and Google's driver but I've yet to find a definitive answer, I now use a USB C card see http://forum.xda-developers.com/pixel-c/help/windows-10-pixel-c-type-c-ports-t3414423
hey guys, I just got my OP3, I want to open the bootloader before I store some data that will be erased anyway when unlocking, I enabled USB Debugging & OEM unlocking & Advanced reboot and then I accepted the RSA Fingerprint popup. (Then, when running adb devices, I got the id of my device).
Now, I am in bootloader mode, and when running fastboot devices, I get nothing. I already installed Oneplus drivers when first connected the device.
In Device Manager under Other Devices I can see a device named "Android". When trying to install the drivers manually by browsing devices I have on my computer, I can only see "Samsung ADB Interface" and I am afraid installing this will not work when trying to unlock the bootloader. What can I do? I also have a Kali Linux Laptop if that's helping. Thanks.
Put in fastboot mode, connect to computer and manually select fastboot interface from the device manager "install device/update driver manually" box. That worked for me.

Its fine just search for fastboot devices and see if your device comes up. Mine was showing the same thing and i continued and it worked

Install adb drivers. Having a adb folder doesn't mean anything. You need to install the adb drivers. Delete that and follow the steps from this thread
https://forum.xda-developers.com/showthread.php?t=2588979
All the best.
did your phone prompt up allow adb debugging window when you enter "adb devices"
To unlock bootloader, once you enable "oem unlock " option, you just simply need to restart phone to fastbootmode and enter "fastboot oem unlock" then select yes
update : i already fixed it by installing google usb driver and manually update my Android device driver using google usb driver file thanks tho for the effort to help me
Mine has been giving me a hard time to there was an windows adb update to
u have to accept the RSA key that pop ups on ur phone, if that does not show up it will not enter ADB mode

I found this to be the best solution, for anyone still struggling with this. https://forum.xda-developers.com/t/...ng-up-in-fastboot-mode-windows-10-11.4194491/
I wanted to root my razer phone 2 because I rooted my old Samsung, but after unlocking my bootloader I decided against it and now ive spent about 2 days trying to lock my bootloader again with no luck.
ive tried many different usb drivers and non of them show my device under the "fastboot devices" command in adb or fastboot but I can show the device under adb devices which im aware is rather easy
ive seen many people have this issue but they don't really show/tell how its fixed! ive tried different usb sockets too!
the device name in my device manager is "SAMSUNG Android Phone" (while the phone is in fastboot mode) with the sub driver called "Android Bootloader Interface" if anyone has any kind of advice or tips to get my bootloader locked again please share!
okay, so after a lot of looking around.. I found this.
"1) - To unlock the razer phone bootloader do the following
2) - Install ADB + Fastboot and google usb drivers
3) - Enable developer mode by going to settings, about phone and hitting build number a bunch of times. then go back to settings > developer options and check USB Debugging and OEM Unlock.
4) - Open a command prompt on your PC and connect the phone's usb cable to your computer. Accept the prompt on the phone for trusting the computer when plugged in.
5) - type the following in command prompt without quotes "adb reboot bootloader"
6) - You'll be at the download mode screen with the razer logo.
7) - Make sure the driver for ADB Bootloader Interface was installed. If not you'll probably have a device called Android under "Other devices" in device manager. If this is the case, install the google usb driver.
8) - In command prompt type the following without the quotes "fastboot -i 0x1532 devices" and make sure your device comes up and not just a blank response.
9) - If it came up now just type without the quotes "fastboot -i 0x1532 flashing unlock"
10) - This will bring up a prompt on the phone itself to unlock the bootloader, use the volume button to navigate to yes and press the power button to confirm.
11) - The phone will reboot and will show a message stating "Your device is unlocked and cannot be trusted" on each boot to show that it is unlocked."
FIX - it was the "fastboot -i 0x1532 devices" I was doing wrong.. I was not putting the "-I 0x1532" i now feel stupid.. but idc i locked my phone and im back to stock finally! (ill probably end up trying to root it again some point in the future :| )
