I have a Nexus 7 2013 that wont boot. USB Debugging was not enabled. At this point, I am just trying to wipe the machine with a stock image, but I am having trouble.
I have installed the sdk and drivers (so many drivers!)
Recovery mode fastboot does not recognize the device.
ADB recognizes the Nexus, but I cant seem to get it to do anything with it.
e: failed to mount anything.
I have read through so many forum threads that I'm just overwhelmed, and they all seem to require the machine being in USB debugging mode before any changes can be made.
Please help or tell me what pertinent information I have omitted.
Thank you
I think USB debugging only matters in ADB, which is when the device is actually booted into Android OS. You probably want fastboot, which is a different "application" and set of commands in a command prompt.
Code:
fastboot devices
Does that give you anything when the tablet is in fastboot mode? It should list the serial number of the device, similar to "adb devices" does. If not, it could be drivers, or another issue with the device.
Have you tried unlocking the bootloader? This will induce a factory reset of the current firmware version, which may allow you at least boot normally and take any available OTA updates.
Hello,
fastboot devices lists nothing, while adb does show the serial number.
I have used so many tutorials and a couple of toolkits that now I have no idea what is happening with my drivers.
Unlocking the bootloader to force a factory reset sounds amazing, but all the information I can find says I need to have USB debugging enabled to do so. I can not boot into the system to enable it.
Is there a way to force a reset without USB debugging?
Thank you
Usb debugging is irrelevant. Forget about it, it's only used when the system is booted.
You need to get fastboot devices to recognize the tablet.
Uninstall any and all toolkits and drivers. Redownload the sdk. Boot to the bootloader and plug it in, the drivers should install automatically. If not install the google usb drivers from the sdk manager in the sdk.
Try fastboot devices again. If it doesn't work try a different usb cord/port/computer.
You are in the bootloader when running this command right? Not the recovery? I think with the tablet off it's volume down and power. The screen that says start in big green letters at the top and has device info in the bottom left is what you want.
Edit: Did you boot to recovery and select the options to wipe data and cache? Sometimes thats all thats needed.
Also booting to recovery and performing a factory reset may be sufficient.
ADB will indeed function in recovery. I don't think you have to enable USB debugging to get this to work though.
Are you typing fastboot devices while booted in recovery? Typing fastboot devices while in recovery or booted into Android will do nothing.
hello, thank you for your advice. I now get the nexus seen by fastboot (and win 7) but have hit a wall. The last time I had my computer and the nexus together was weeks ago, when I my computer BSOD during what I thought was a simple flashing of the the stock image, but turned out to be hours of the nexus saying it was erasing personal data ... and then crash. I have replaced and added fans so my cpu wont overheat again, so please offer ideas why "fastboot flashall" or "fastboot flash image-razor-kot49h" wont work.
I appreciate all responses, and believe the answer is either very simple or a catastrophic hardware failure. I base this belief on what is left in my head after smashing it into the wall so many times over the last month when my wife asks me, "have you fixed my nexus yet, or do I need to figure out a way to buy a new one next month?"
I am stuck at unlocking the bootloader. I have highlighted "yes" on the nexus and pressed power and my command window says "erasing user data." It has said this for the last 18 hours. This is the second computer I have tried this on, using 3 different usb cables. What am I missing?

This may help...it may not. But I was having issues getting my bootloader unlocked also when I started on mine. My remedy was to
1 plug in the nexus into the usb
2 I run Linux so it gives me choices on what to do with newly plugged in usb device. I noticed two identical choices to mount device. Choosing one just mounted the camera for some strange reason. I closed that window, then chose the other choice to mount device, the window opened and my full internals were there in the window
3 from a terminal I just wrote a prompt: fastboot oem unlock
and for some reason, it unlocked.
To sum it up I'm convinced it has something to do with how the device gets mounted. At least on mine anyway.
As for activating developer from a terminal I read it could be done but never tried it myself, if you want here's the link for the info, read the second answer down.

Tried to edit but anyway:
After re..re, rereading your post, and responces. Have you tried the old fashioned way
Hold down the (down volume) button at the same time the (power) key.."Together" If you get anything that pops on your screen let go of the keys, one tap at a time tap the volume up or down key ONLY, until it says (START), its in green type. if you get there you should be ok, to move along
Wondering if any of you guys can advise me - having strange problems with fastboot (windows 8.1 and Zenfone 2 ze550ml). Wanted to flash the pre-rooted image to my device so downloaded it and extracted to the flashtools folder and renamed system.img then hooked up my phone. Checked adb drivers were installed and adb devices command returns a code string, so assumed all was good to go with flashing. However, on entering any fastboot command it just sits at "waiting for device". Tried manually starting the phone in fastboot and then connecting it, and this did enable me to execute fastboot commands (reboot or reboot-bootloader work). However, fastboot flash system system.img just results in a message about file size and then "failed to load system.img"

You need to rename the system image to system.img and put it where the fastboot file is. It's looking for it but can't find it.
No, don't think that is my problem - as I said I extracted it to the flashtools folder, so it is already where the fastboot file is. And anyway, though I'd like to solve the problem of flashing the system.img, I am kind of more interested in why I can't get past "waiting for device" without first manually entering the fastboot mode.
Cause Windows sucks. I'm on Linux and no issues. Maybe someone on Windows can chip in?
I can easily do a quick ubuntu install and try it that way if you think it might work better. At the weekend maybe. Could you give me some pointers on how to do it in linux if I do? Would be much appreciated!

I have encountered that problem with the "waiting for device" while I was flashing pre root rom.
Try the cmd adb devices
Then it will list the device connected to the computer...if it says not authorized, then you need to check the phone which is turned on and a pop up window with the RSA key and tap on trust this computer or something..
Then repeat adb devices and it should say allow or something..then it will allow you to flash.
(double check the commands online, I might missed something)
Nah, don't blame Windows... I flashed mine with Windows 10 and worked wonders.
Also... could it be that PC isn't USB 3.0? Perhaps system.img transfer is stopped somewhere during the copying phase?
Thanks, but actually the first time I tried it I did the adb devices command and authorised my pc on the phone. When I connect and do adb devices now it shows the string of numbers code for the device. However, still can't get past "waiting for device"
My pc has both usb 3 and usb 2 ports. Tried on all of them and with various different cables including the asus issued ones, all to no avail.
Can u post a pic of your flashtool folder?
Sent from my Nexus 7
Here is a snap of my platform-tools folder and cmd window
Did you manage to find a solution to this?
I updated the zenfone 2 via OTA to the latest system update.
Ive read and downloaded all relevant files to install the pre root img from the correct sources.
Now when I hold power + vol up. I can see the droid on its back. I choose the RECOVERY option and press power button to select.
When phone reboots it goes to droid icon and says installing system upgrade.................then error appears! No recovery mode!
All the correct drivers are installed into Windows 7, the phone asks me to allow RSA key connection to laptop.
Ive tried the flash tool installer 1.0.7 with phone connected and system img (renamed) and still nothing.
Anyone got any ideas?
Ive factory reset twice in a row and allowed debugging.
Ive placed the (renamed) system.img into the fastboot folder and tried the open command with line ' fastboot flash system system.img' and the reply is usually unable to read system.img or device waiting.
Ive installed the latest android sdk develppment kit and still unable to root using this pre root image.
Im familiar with android and how to follow instructions on rooting, but this zenfone 2 is mind boggling.
Thanks for reading. I know its someone else post. I didnt want to start a fresh post with the same dilemma.
Any advice on whats going wrong would be appreciated.

Hit power and vol up again, just really quickly. Don't hold it, just press and let go. Sometimes it takes several attempts.
hkdmjack, yes your right managed to do it at last.

Hi guys, I am facing quite a difficult problem at the moment.
My friend has "accidentally" attempted to use an Asus Zenfone 5 rooting method to root his zenfone 2 550ML.
When I received it to take a look at it, I instantly noticed that I could not get into fast boot (or droidboot). I expected to see usual droid with text on the left side and also expected to be able to select from a number of options using the volume keys (i have some past experience), but instead am met with this solid usb logo. One like this: h ttp://zenfo ne-blog-forum.2 8820.n7.nabble.c om/file/n4 5/P_20140728_051139 .jpg (remove spaces)
I did some research, and found that there were many "bricked" zenfone 5's which were stuck on this usb logo, however this zenfone 2 can start up normally and be used throughout the day normally. Only when I try to enter fast boot, by either ADB commands or by power + volume up, I cannot get past the usb logo.
I have linked up the ZenFone to my computer, and confirmed that ADB devices correctly lists the device (I have usb debugging enabled), however, when I try to go to fast boot and am met with the usb logo, my computer does register and detect the phone, however, under device manager it has a yellow triangle with the device named "" MOOREFIELD". When the ZenFone 2 is in this usb logo state, I cannot access any fast boot commands. I am quite stumped at the moment.
Any help please? By the way, I use a windows 8.1 computer with usb 3 ports. However, I have tested using different cables, and on a windows 7 laptop with usb 2 ports, still to no avail. Should I try and update the firmware using Asus' software? Or is there a better solution?
Thanks
Edit: My friend claims that he did not see at any point in time, the flashing on the zenfone 2 start. He was faced with a "<waiting for devices>" or something similar message, telling me that the phone was not fully in fast boot yet. If I can get it into fast boot, I am sure I can reflash the custom stock onto the phone, and most issues will be resolved.
same error
i have the same error by my zenfone2 after update
please help

my orginal firmware is CN and i wanted to change to WW mode i tried by pc .... now when i conect phone t pc it want moorefeild driver for conection and i dont have those ,,
Whenever I try to flash system.img it gets stuck on "writing 'system'..." and just hangs there. I have left it for over half an hour and it still didn't work. Does anyone know a solution to this problem?
Hey guys,
So after a while without any responses, I headed over to Asus customer service to receive a very unhelpful reply.
I gave up hope of finding an answer online and so I decided to take a leap of faith by updating the firmware via the Asus Update app on the phone.
I upgraded from 2.14 to 2.15 and miraculously fastboot seemed to have restored itself. I am not sure whether or not every single update restores fastboot, or whether the update to 2.15 does, but I'm glad that it has been fixed.
My previous problems of being unable to detect fast boot devices has been resolved. Hopefully others who have experienced the same issue can find this post helpful.
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.
Phone is detected by "adb devices" but not detected by "fastboot devices"
I purchased a used P3a XL from Swappa. I would like to install a custom ROM. As we all know, in order for me to do that I need to unlock the bootloader. I think the phone is a Google Edition (checked SKU on box against what is sold in stores).
I have done quite a bit of research before posting here and think I have the process correct. I have enabled developer mode and toggled the OEM unlock option. I am able to "adb devices" and see the phone on my computer terminal. I "adb reboot bootloader" and the phone reboots in to "Fastboot Mode". When I do "fastboot devices" nothing shows. When I boot in to fastbootd (via stock recovery) and execute "fastboot devices" I can see the phone. I execute "fastboot flashing unlock" and it fails with "fastboot flashing unlock failed remote: unrecognized command flashing unlock".
I have tried this on my PixelBook with Linux installed and on my Ubuntu lab machine. Both of those machines give me the same results. I tried with my Windows 10 laptop, but the phone isn't detected by any of my USB-C to USB-A cables.
I have factory wiped the phone a few times and attempted the steps above, but it results in the same thing. Phone is not detected in fastboot. Interestingly, I am able to sideload the latest OTA (QQ3A.200605.001, Jun 2020) without any errors. After sideloading the latest OTA, I am still unable to unlock the bootloader.
I suspect one of two things:
1. The phone is a VZW/Sprint/T-Mo edition. Even so, VZW edition can be unlocked. I tried that method (found an XDA thread to do that).
2. Something is wonky with the phone (bootloader software)
Unfortunately, since I bought it second hand, I do not think Google would honor the hardware warranty to issue me an RMA.
What do you folks think may be an issue?

Sideloading is an adb function, not fastboot. Make sure you have the lastest Android platform tools. This doesn't mean you can unlock the bootloader but to get fastboot working.
Also make sure you have the oem cable or at least a decent cable, and use a 2.0 port if possible. I've seen other a/b devices refuse to work or give half commands with 3.0+ ports. What does it says underneath oem unlocking in dev settings? I've attached the latest adb/fastboot files just in case you might need them.

I just updated my Ubuntu machine with the lastest SDK, so both ADB and Fastboot were updated. The phone can be seen with "adb devices". It can be seen with "fastboot devices", but only if the phone is in fastbootd mode. Wouldn't this confirm that fastboot works on the laptop?

Yup, tried that as well. I even went as far as wiping one of my lab machines, installed Windows 7, copied and installed the command line tools only from here: https://developer.android.com/studio#downloads, but no dice. For Windows, I think it's a cable issue. I'm getting new USB-C to USB-A cables delivered tomorrow. Once I get them, I will try on my Windows laptop.
Update to my issue...
Bought a 3 pack of Anker cables. Plugged each of them to my phone and to each of my Win 7 and Win 10 laptops. Both laptops are able to charge the phone, however the don't detect the phone for data transfer/USB debugging. I checked device manager, deleted/uninstalled all Android devices that were listed (including my first generation Pixel XL), rebooted my laptops and tried again. No dice... At this point, I'm chalking it up to the Pixel 3a XL phone itself and an issue with the hardware.
Note to self... Buy a brand new phone for an extra $100 and I would have saved myself over 4 days of troubleshooting an issue.

Yup, I know that I need to change it to data transfer, however the phone isn't detected by either of my Windows laptops. The phone is only detected via ADB on my Chromebook. I can do an "adb reboot bootloader" and it'll accept the command, but "fastboot devices" or "lsusb" shows no devices.

Yup, my first gen Pixel XL will notify me when I pull down the notifications, but the Pixel 3a doesn't.
I ended up setting up the phone and used it for a fewdays. It works fine, however I'm used to running AdAway, AFWall, EX Kernel Manager, Greenify, High Brightness Mode, NapTime, Titanium Backup and Viper4Android. There are workarounds to enable Greenify and NapTime via ADB, but it's a moot point without the other root dependent apps.
Updating this thread to close this out.
Bought a brand new Pixel 3a XL from the Google store. I was able to root without any issues on my Windows 10 laptop. I attempted the same exact process with the same USB port and USB cable for the Pixel 3a XL that I bought from Swappa, but it didn't work. This confirms my educated guess that it's a hardware issue on the phone.
The secondary market may soon be flooded with Pixel 3a XLs once the Pixel 4a is released. Before you get burned on a non-rootable phone, ask the seller how long they have owned the device and check the warranty on it. As of this post, you can check the IMEI Here: hxxps://store.google.com/repair (replace the hxxps with https).
Good luck!
You need to download the google usb driver and update the Pixel 3 driver in Device manager with the usb driver. Then the computer will recognize the phone as a fastboot device while it's in bootloader.
For me what solved this was I wasn't adding the "platform-tools" folder to my path.
I was using "fastboot.exe flashing unlock"
But once I added to path and did "fastboot flashing unlock" it worked like a charm
On Linux, did you try sudo fastboot flashing unlock? This is the only thing that works for me. Sudo before all fastboot commands.
In my case on Ubuntu 20.04, it was a USB 3.0 port problem. It was detect device with fastboot devices but other commands does not has a response. My laptop hasn't got a USB 2.0 port. Then I disabled internal USB 3.0 support in my BIOS and now fastboot is working normally. But all USB 3.0 support is stopped. It seems USB 2.0 hub is the better option. I will set back the BIOS setting later.
Yesterday i bought the G020B version, and the same happened to me while unlocking bootloader, fastboot keeps on <waiting for device> like if the phone was not even connected
I searched for a driver that could work and found this (For windows)
Basically, my system can't detect properly the phone because the driver was not 'updated'. (Even when i can use fastboot on other devices)
Hope it works for you or everyone here.
I have a brand new Moto G7 Play XT1952-4 (old stock, new in box) that I bought specifically to flash LineageOS. I have done this process with two previous Motorola phones over the years, but I seem to be the only person on the Internet with this particular problem: When I restart the phone into bootloader/fastboot mode, any fastboot commands that I send over to the phone hang the process. So this works:
>fastboot devices
XXXXXXXNVN Motorola Fastboot Interface
But this or any other fastboot command that communicates with the phone does not work:
>fastboot getvar all
<process hangs, ctrl-c will not interrupt it>
Sometimes while this command is hung, the simple interface on the phone locks up and the volume up/down and power keys are not responsive. If I unplug the USB cable, the fastboot command will fail and return and the phone is responsive as normal. What is strange is that fastboot worked initially.
When I first powered up the phone without Internet access, I enabled Developer mode and ADB debugging, and fastboot worked: I was able to run 'fastboot oem get_unlock_data' and I used that to retrieve my unlock code from Motorola. When I ran 'fastboot oem unlock XYZ' the phone told me to enable OEM unlocking. I rebooted the phone to find this option was disabled, so eventually I connected my phone to Wifi and the option was enabled. However, the phone began applying updates, so I waited until the updates were applied and resumed my operation. This is when the trouble started.
From that point on, fastboot has failed to work: no error messages, it just hangs. I have tried two laptops, two USB cables, two versions of fastboot (the Ubuntu 20.04 stock version and the 'latest' 30.0.4-6686687 from Google). I have factory reset the phone from Settings, factory reset from Recovery, and I let it go ahead and update to Android Q and repeated all of these things.
The only thing I am left with is this is some kind of hardware error with the USB port on the phone. If so, I wonder if I can make a warranty claim on 'fastboot commands do not work'? I am able to 'adb shell/push' fine, and the phone charges fine.
Any ideas?
I had the same problem i reinstalled adb and fastbood but that not worked than i reinstalled my entire system and installed fastboot + adb and it worked
The the command on a other pc out.

I think if it was a hardware issue, 'fastboot devices' would not display you ESN, thus indicating fastboot is ready. But I have to agree that this is quite unusual behavior for fastboot mode to hang up like you described. It could certainly be a corrupt bootloader partition (/aboot ??). You should try using the Lenovo-Moto Smart Assistant utility to do a full rescue of the firmware. Treat the phone just as you would if it was unstable or failing to boot. The LMSA utility actually utilizes fastboot mode to do the firmware rescue. So if you could get this to work it could possibly solve the problem. Here is a link to the 32- & 64-bit Windows versions of LMSA. I know you mentioned using Ubuntu, but I'm not sure if the utility is available for Linux. https://support.lenovo.com/us/en/downloads/ds101291

We have a Macbook and I downloaded the "Command-line tools only" kit for MacOS from https://developer.android.com/studio/, and it worked! Strange that it didn't work on two different Linux machines with essentially the same software. Of course, there could be some other problem that I'll run into later, and I'll use the LMSA utility if so. Thanks for the ideas.

:good:
Adding this here as I ran into the same issue and was able to work around it.
Performing fastboot "oem'"commands from my Linux Mint machine (Ubuntu based) was failing.
I discovered that if I ran the commands from just any directory, the command would hang (and not even a ^C would break the command!). This action referenced the file '/usr/bin/fastboot'. (This file from the 'fastboot' package.)
$ fastboot oem get_unlock_data
<hangs>
HOWEVER, if I referenced the version of 'fastboot' stored in the Android SDK directory '/usr/lib/android-sdk/platform-tools', the command worked as normal.
$ /usr/lib/android-sdk/platform-tools/fastboot oem get_unlock_data
...
(bootloader) Unlock data:
<snip>
What's strange:
- Both files (/usr/bin/fastboot & /usr/lib/android-sdk/platform-tools/fastboot) are both from the 'fastboot' package
- Both files are identical.
Why one would work and the other wouldn't is a mystery for another day.
