fastboot mode adb - Nexus 10 Q&A, Help & Troubleshooting

I downloaded minimal adb and fastboot from another thread
I had to disable "enforce driver signature" to install drivers for the device. Now I have an item in my device manager called "Samsung Android Phone" with "Android ADB interface"
I have tried command "adb devices" and it recognises my device
When I try "fastboot devices" nothing happens.
Maybe I don't know how to put the device into fastboot, but i thought all i needed to do was press and hold : power vol+ vol- and the device would reboot into fastboot.
Ultimately I am trying to unlock the bootloader and root, but the toolkit I am using get stuck as "waiting for device"
Any help would be appreciated

You probably did this but just to check:
1. Start cmd.
2. Navigate to your adb/fastboot folder.
3. Check if USB debugging is enabled.
4. Type "adb reboot bootloader" in the cmd window.
5. Type "fastboot devices".
6. Type "fastboot oem unlock" (THIS WILL WIPE ALL YOUR DATA, data+internal storage).
7. Type "fastboot flash recovery /path/to/recovery.img".
8. Navigate to recovery option in the bootloader. And boot into recovery by pressing the power button.
9. Flash the latest supersu and wipe cache and dalvik cache.
10. Reboot.
11. Profit.
If it doesnt work at the step "adb reboot booloader" or "fastboot devices" you prabably are having a driver issue.

I tried this, but all my device does at step 4 is a normal reboot. I am able to fully use adb without any issues...
My device is a Titan Allwinner A20 Softwiner sun7i Tablet...
Does this mean that it does not have a fastboot/bootloader mode?
Thanks for your help...

I only know this for the Nexus 10. Maybe look up the thread for your device and see whats there. Or use google

Hi,
This forum is dedicated to Nexus 10 only, I don't believe that we can be of wide help for you .
The fastboot commands only work for Nexus devices, so as you don't own one and can't even get boot loader mode, then I'm sorry but here is not the place that you may seek advice.

True this isn't the place for the question, and the answer is you probably do not have a bootloader that is capable of interacting with the fastboot binary.
However fastboot is not only for nexus devices, virtually all HTC android devices are able to use fastboot, same with many Motorola, Sony and lg devices.
But again, more than likely your device will not work with fastboot
Best of luck!

Fastboot, waiting for device.

Hi guys, I recantly decided to update my gt540 from 2.1 to 2.3.3
I followed steps by steps on by this tutorial - http://fdapps.comuf.com/downloads/The LG GT540 Optimus reference page.pdf
Installed rom with fastboot, tried to install Clockwork with fastboot, I typed fastboot flash recovery C:\recovery.img , and then there's <waiting for device> , doesn't go further, I have everything installed sdk, usb drivers and usb debugging activated. Maybe there's some problem with key combination, to get in fastboot. From google I understood, that I have to turn phone off, then press and hold camera + press power button! I did other combinations too, but didnt work.
Just waiting for device..
Any ideas? I read, that if you're in fastboot there's just a black screen, and on pc desktop appears fastboot usb. I have non of that.
Thanks for help in advance.

http://www.mediafire.com/?pbigrb8cimmxa4d
* these drivers are for your pc to recognize your phone in fastboot mode, they are not the normal LG usb drivers
4. for install the drivers abouve follow these smll tutorials
* if using windows 7:
http://developer.android.com/sdk/win-usb.html#Win7
* if using windows XP:
http://developer.android.com/sdk/win-usb.html#WinXp
once is installed plug your phone in fastboot mode to your pc, now your pc has to recognize your phone wait until it finish installing the drivers and read it properly
5. unzip the new ROM files into C:\*SDK\tools
6. open CMD Terminal and go to C:\*SDK\tools, type:
cd C:\*SDK\tools
7. once in, type
fastboot flash recovery recovery_clockwork_3.x.x.x_swift.img"

Already did that with no success... .
If your device is rooted, installed a custom recovery and you're able to get into recovery mode Windows should be able identify your device without asking for RSA fingerprint or something.
Get into recovery mode and try "adb devices" from cmd after connecting your device to pc. What do you see?

I'm not rooted,
when rebooting with power and vol- windows recognize the device but "adb devices" gives nothing"
If I select recovery mode the nexus disappears from windows device manager
Check windows device manager to see if you can find any devices without drivers especially something about ADB or Android.

Nothing, when in bootloader (the one with the green robot win belly open) it gets recognized as "bootloader adb interface"; when in recovery (green robot with red exclamation mark) there is nothing in device manager

So you can issue commands over fastboot then? You can flash stock firmware images over fastboot to get everything working again.

but when if fastboot the command "adb devices" return nothing...
When you're in fastboot mode you don't see your device online over adb, you can freely issue any commands from fastboot if your computer recognizes the bootloader interface.

How to activate new Google Nexus 7 tablet when the Google is blocked (China)

I ordered this from amazon.com USA and received it in China
I have just turned on this device and this is the first screen and there no option to skip it unless I complete it. When there is no WiFi connection, there is no option to click next.
So when I click next after connecting to WiFi which is the only way I can have the NEXT option enable so when I connect to WiFi and click next, after some loading screen I get this message: ERR_CONNECTION_RESET.
I am afraid if this is because the device must connect to some google's server (which is blocked in china) to get past this first step.
P.S. This is NOT my account registration it (as it didn't ask me about it yet) I think its device registration of some kind in the newest android stock version. Hope you understand
Is there a way to activate it without an internet so I can get past this process? Please advice.
start mobile internet as wifi hotspot. connect nexus 7 to it. and there u go. afterwards it wont ask again.

I think you did not read my post clearly... Yes you didn't
You might not like this solution (as it involves unlocking the bootloader and flashing a custom ROM), but you could flash a custom ROM like CyanogenMod. It doesn't come with Google Apps.

The following steps is in case you have Nexus 7 (2012), Wi-Fi edition:
1 - Install Android SDK (platform-tools) and Google USB Driver (read Software Requirements and Driver Installation)
http://forum.xda-developers.com/showthread.php?t=1907796
2 - Download TWRP for Nexus 7 (2012) Wi-Fi edition
dl.twrp.me/grouper/twrp-2.8.7.0-grouper.img
3 - Boot your tablet into bootloader/fastboot mode
Power off the device completely.
To enter Fastboot Mode you will need to press and hold Volume Down and Power, all at the same time.
– do not release the buttons.
Release all buttons when the Fastboot screen appears.
– that’s it, if you see the START option listed in the upper part of your screen you’re done.
Click to expand...
Click to collapse
4 - Connect your tablet to your computer via USB (if you don't have it connected already)
5 - Type in the command prompt "fastboot devices" (don't forget to open the command prompt and go to the fastboot folder)
You should see your device listed there. You don't see it? Don't continue and inform us.
6 - Move the file twrp-2.8.7.0-grouper.img to your fastboot folder
7 - Type "fastboot oem unlock", after unlocking the bootloader type "fastboot boot twrp-2.8.7.0-grouper.img"
Wait a few seconds and your tablet should boot into TWRP. TWRP is a custom recovery software for your tablet. It allows us to perform backups and restore your device, as well as installing custom ROMs. If you don't know what is a custom ROM, think of it as a "modified Android".
8 - Download CyanogenMod for your device
Here's the latest stable version available:
https://download.cyanogenmod.org/get/grouper-snapshot.zip
9 - In TWRP, go to "Wipe", "advanced wipe" and select "System" and "Cache" (and/or dalvik-cache). Wipe those partitions.
10 - In TWRP, go to "Advanced" and click "ADB Sideload"
11 - In your command prompt, type "adb sideload grouper-snapshot.zip" (replace "grouper-snapshot.zip" with the name of the zip file of CyanogenMod you downloaded)
12 - Wait until it finishes, it will take a few minutes. Don't disconnect the USB cable!
13 - Once it finishes, reboot to the system
Let us know if it worked
If you are stuck in a step it's better to come here and say it instead of trying to discover by yourself. Some people bricked their devices because they didn't knew what they were doing.
Also, I'm not sure if you can download the Android SDK, because of the censorship. Let me know.

No Fastboot Option In Bootloader

I restarted my phone this evening, and when it booted up I got a "decryption unsuccessful" message. When that happens it appears my only option is to flash a factory image. So I download the most recent image, and when I get into the bootloader I see no option for fastboot.
When I'm in TWRP (3.0.2-0) I can see my phone listed in recovery or sideload when I run "adb devices" from my computer, but no devices are listed when the command is run while on the main bootloader screen.
Not sure if it matters at this point, but I had the 20160821 Pure Nexus build installed when this happened.
How do I get my phone into fastboot mode so I can flash the factory image?
Thanks so much for your help.
It sounds like you may not have the latest drivers for the Android SDK or ADB toolkit.

Not sure what you're talking about. Turn the phone off. Hold vol down + power, to boot into the bootloader / fastboot.
Run the fastboot devices command, and you should see your device. That's where you can flash your system images.

So, if I'm at the bootloader's main screen, I should be able to see my device when I run the command "adb fastboot devices", right? Cuz that's not happening. Also, when I use the volume rocker to see the available options fastboot isn't listed.
When I go into recovery from the bootloader and run the command "adb devices" I see my device listed with "recovery" next to it. When I launch ADB sideload from TWRP, I also see my device listed with "sideload" next to it.
So, I can run fastboot commands when I'm in the bootloader even if "adb fastboot devices" returns nothing?

Thanks. I'll do as you said and report back. Maybe what I'm doing wrong is recalling the bootloader unlock procedures where "adb" precedes some of the commands when executing them from the Windows command prompt.
Just to be ridiculously clear it's:
1. While unplugged, Power + Volume Down to enter the bootloader.
2. Once in the bootloader connect USB cable.
3. Navigate to the SDK platform-tools folder, and from the Windows command prompt execute "fastboot devices". Then I should see my device listed.
Sorry if I'm being dense.

Thanks for your help everyone. I'm back up and running now. My problems stemmed from a misunderstanding that once in the bootloader I'm already able to execute fastboot commands and didn't need to select a fastboot option from the bootloader. And I had a misunderstood how to execute the fastboot commands from the command prompt.
Many thanks to everyone setting me straight!

fastboot responds as above. I cannot install the MiFlash-2017-7-20 version. Windows complains. I conclude that version must be a w10 64-bit app, although it doesn't say so.
win10 64-bit
MiFlash-2017-7-20 installs and runs, but does not see the device. Apparently, the adb drivers are at fault. I have turned off signature enforcement and tried installing various versions of the adb drivers. The device manager shows them as installed, but reports that they cannot start.
Centos 7 linux
Adb drivers install. "Fastboot devices" reports correctly. All other fastboot commands fail, i.e. they hang. I tried installing the tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794 image using the linux shell script provided, but that just hung also.
Is this phone well and truly bricked at this point? Is there any other recovery available?
I think it is not hard bricked by any means. Try booting into the Quallcomm EDL and try flashing the fastboot rom with MiFlash too. You can setup a virtual environment in which the flash tool can run and the drivers can install properly.
Maybe you should boot to other partition (A or B)
Just fastboot then try boot to other partition, hope it works

As he said, he can't execute fastboot commands so that isn't a option.

1. You say that "fastboot devices" works, but "fastboot reboot" not. What error do you receive? Could you paste full log?
2. Sometimes drivers in Windows must be installed manually - open device manager, find unknown device, choose from list and find and choose "android fastboot" or "android adb" device depending on the mode you're in. If you have installed fastboot device before, you should be good to go. Otherwise you'll need to download minimal adb package (https://freeandroidroot.com/download-minimal-adb-and-fastboot-all-versions/), or Google development kit (much larger).
3. stock recovery mode is started by pressing "power button + volume up", once "no command" screen appears, press shortly "power button + volume up" to show the menu.
4. please post full log of command "adb devices" as well
Hola guys. I got mostly the same issue here. While I still can use adb comand while on fastboot. But i can't flash stock rom using mi flash.. i mean after the done notice my phone still stuck and wont reboot. Like the flash doesnt apply to the phone. I wonder what was wrong

Unpack ROM image, extract directory, open cmd, run "flash_all_except_storage.bat" (you might want to remove command "fastboot %* oem lock" from the end of bat first), check/show log.
The easiest thing that worked for me in a similar situation is going into stock recovery and factory resetting the device. I had tried pretty much everything before this and my device was still dead for 1 and a half days before i hit upon this idea without any guides and it worked!!
Do this to get into recovery mode:
1. Power off your phone
2. Press power button and volume up button at the same time
3. You will get "No command" Screen with Android robot with exclamation mark
4. Press power button (don't release) then press volume up button..
5. You will enter into recovery...
The phone may just reboot normally the 1st time you try it as it requires some practice to get it right, but keep trying..
Hope this helps

1. I tried this method to boot into EDL with no luck. Is there any other way?
C:\Downloads\xiaomi mi a1 root>adb reboot edl
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
error: device '(null)' not found
2. On my win10 32-bit installation I am able to run MiFlash-2017045. It reports the device. I attempted to flash this image:
tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794
It completed and reported "success" however it did so in only 7 seconds, so it must not actually have succeeded. In any case the phone still will not boot.
3. However, I distrust MiFlash 20170425 because it comes from an androidmtk.com site and the processor is Qualcomm, not Mediatek. So I attempted to install MiFlash2017-07-20. However, that program will not install on my win10 32-bit installation. There is a Windows msg saying it cannot be installed, but does not give a reason. I suspect it is a 64-bit program. So, I installed MiFlash2017-7-20 in a win 10 64-bit installation. The program does run, but it does not see the device. I suspect that the adb drivers do not install correctly. I did turn off signature enforcement and the drivers appear to install, but the device manager reports that the drive cannot start.
The tissot images include bourne shell scripts to install, so I installed the adb drivers on my Centos box. Fastboot reports the device, but just as in win10 no other fastboot commands work. So, even though I did try to execute the install_all.sh script, it just hung on the first "fastboot getvar product" command.
So, I do not have a way to flash the stock rom.

1. All fastboot commands, other than "fastboot devices" just hang on "<waiting for device>" with no error message in the linux environment. In the win10 environment they timeout after a few seconds with a message like this:
C:\Downloads\xiaomi mi a1 root\tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794\tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794\tissot_images_7.8.23_7.1>fastboot oem device-info
...
FAILED (command write failed (Unknown error))
finished. total time: 7.000s
2. I had already installed adb-setup-1.43.exe, but I ran it again anyway. Same result.
3. The device will not boot into recovery mode. Pressing power and volume up brings it the "no command" screen with the supine robot image.
4. C:\Downloads\xiaomi mi a1 root>adb devices
List of devices attached
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
No other output.

Use fastboot commands manually. Mi flash tool is very buggy. Many time it doesn't work.

Did the command:
C:\Downloads\xiaomi mi a1 root\tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794\tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794\tissot_images_7.8.23_7.1>fastboot getvar product 2>&1 | findstr /r /c:"^product: *tissot" ||
"Missmatching image and device"
So this is a little interesting. However, I don't think that the image is actually the wrong one, but that the script cannot get the device info since both "fastboot getvar product" and "fastboot oem device-info" fail on a timeout.

When I do that it just keeps going back to the "no command" screen. I think the recovery image is either damaged or gone.

1. & 2. It sounds like you don't have installed fastboot drivers (install them manually via device manager) or phone isn't connected in fastboot mode (make sure there is a picture with fastboot written on the phone).
3. this IS the recovery mode, just press power + volume up again to show the menu
4. you won't see ADB devices in fastboot or recovery mode, unless you enable ADB sideload from recovery
Device Manager shows:
Android Phone

Wrong drivers then, it should say Android bootloader interface. Reinstall them correctly.
1. I did the manual install, but I don't see anything labeled "fastboot driver."
Device manager now reports:
Android Phone
Android ADB Interface
Android Bootloader Interface
Android Bootloader Interface
Android Composite ADB Interface
However, all these entries have a warning symbol on them. The Device status for each is:
This device cannot start. (Code 10)
The specified request is not a valid operation for the target device.
Is one of these the fastboot driver? Apparently not, since the behavior of the fastboot command hasn't changed.
When I try using the fastboot command the A1 shows "Fastboot" with the rabbit character and the sick robot.
I should mention that in the Centos environment I have installed the android-tools package, which include adb and fastboot drivers and tools. The behavior of the fastboot command there is the same.
So, this leads me to believe that the problem is the A1, not the windows or linux environment, but I don't know enough to know for sure. Also, I would assume that if the fastboot drivers were not installed, the command "fastboot devices" would fail, but it doesn't.
3. At the "no command screen" if I do press and hold the power button and then the vol. up button it boots right back into the "no command" screen. There is no menu.
4. With no recovery menu I can't set any options.
Uninstall/remove everything with android name in it, disconnect phone, reconnect phone in fastboot mode. Make sure that there is only one item under Android Phone - Android Bootloader Interface. You should not see 4 devices - do you have Android emulator running or anything else connected?
When in recovery, do not hold power + volume up, just press it briefly. Sometimes it takes few tries to show the menu, but I can assure you that it's there.
Yes! You're right. The recovery menu is indeed there. I didn't know that it had to be a short press to bring it up. Thanks.
Device manager now shows only one "Android Bootloader Interface" entry. I am not running any emulator.
So now what do I do? Do I need to flash the tissot... image? The fastboot command still behaves as before.
Quick Google search suggests to avoid using USB 3.0 ports. So..maybe try another ports on your PC..?
