I am trying to unroot and re-lock my xoom and everytime I try to use a fastboot command all I get at the command promt is "waiting for device". I have installed the moto drivers and adb is working fine, just no fastboot. Please help... Thanks in advance!
did you reboot your xoom into bootloader mode? (adb reboot bootloader)
does it show any devices when you type
adb devices
Yes,
adb devices returns the attached device with the serial number.
adb reboot bootloader reboots the device and it say starting fastboot protocol at the top. then when I try to use fastboot flash boot boot.img or any other fastboot command all it does is say waiting for device and that's it..
usb debugging is on? should be if you see the device with adb devices
try to flash another cwm - like rogue version
if you do that - same error?
./adb reboot bootloader
./fastboot flash recovery recoveryroguecwm.img (change real filename )
well, usb-debugging has no effect whatsoever on fastboot.
personally, I suspect a problem outside of the xoom. Have you installed the current motorola drivers using driverhelper? If not, please do so. Please make sure any firewall or anti-virus-software on your computer is disabled or uninstalled.
If you have the possibility, you should try fastboot with another computer.
btw: I'd try if fastboot works with the command fastboot devices. This should return a list of connected and detected devices.
Thanks! For some odd reason my driver needed to be re=installed. After I did that a restarted my computer everything works as it hasin the past!
I was trying to flash a custom ROM on my moto g xt1033. I used choosing the zip from USB otg after wiping and formatting everyrhing but. It flashed but a black screen came instead of cm logo and I was stuck at welcome to cm screen without touchscreen working. http://forum.xda-developers.com/mot...4-4-4-help-t3019082/post58587594#post58587594
Then I tried side loading or pushing method. But problem is adb commands are not working in fastboot mode. They are working when phone is switched on. (Adb devices show serial number and device in normal mode) Fastboot commands are working fine in fastboot mode but not adb. When I type adb devices in fastboot mode there is nothing after list of device attached. So adb push or adb side load give me waiting for device or device not found result. Is it normal. Earlier I have latest Motorola device manager and latest android SDK. Tried uninstalling and installing them, tried changing USB ports, tried rebooting the phone and restarting windows pc several times but still no luck.!!
Yes, it's normal that ADB commands do not work in Fastboot mode. But you can access custom recovery from the fastboot screen.
@lost101 if adb commands do not work in fastboot mode then how "adb sideload" works when we clean install a ROM? Many threads at XDA say it should work

You have to be in a custom recovery (TWRP, CWM, Philz Touch) and enable the 'adb sideload' option.

It doesn't work on all versions of Windows; I think I've had it working in Windows 7. But I mainly use it in Linux - where no driver is required.
I also have windows 7.. Thanks Anyway

It's a driver issue. Your phone is not being recognised. If you boot a Linux LiveCD from DVD / USB, you can access recovery mode ADB that way.
sudo apt-get install android-tools-fastboot
Not sure if this will help but, after completely wiping my phone, I installed TWRP using fastboot commands, booted to TWRP, mount, copy ROM to moto g, and install using TWRP.
If you are in fastboot mode, type fastboot devices and see what happens.

Fastboot Devices command works flawlessly in fastboot mode. I can flash .IMG files. But none of adb commands working. When I type adb devices there is no result after List of Devices attached. So I can't sideload anything
I'm not 100% sure how adb works on the moto g but I don't think adb commands work in fastboot mode. When I connect my moto G to my computer after the ROM has booted and I am at the phone's desktop, I type "adb devices" and I see my device listed. Then I type "adb reboot-bootloader" to get into fastboot mode and adb commands no longer work.
I have Philz Touch on my Moto G and sideloading is an option. I don't think you can side load from fastboot.

I have no idea as I have never used adb to install anything except apk files when the phone has been booted to the desktop.
I always use fastboot commands to install recovery and install stock ROMs.
Using adb to side load may refer to the aibility to install files while the phone is running.

OK leave it. Do you have any idea how to increase 2g/3g speed. Any trick/mod/script?? I flashed cm11 quarx build and internet is painfully slow
Edit- no sideload means pushing a flashable zip to the root of internal storage when phone is in recovery mode. We do it for clean installing ROMs.(Format and wipe everything). After format there is no operating system left in phone so we do sideload rom

Sorry, I don't know how to increase speed except try a different radio/modem on your phone. I rarely use data on my phone because I have an iPad with LTE.

Sounds like your fastboot driver is working fine but your adb driver is not...go into your custom recovery and then check Device Manager in Windows to see if you have all your drivers working properly.
If you are having adb driver issues you could try the Universal adb driver setup file attached.
adb commands don't work in fastboot mode. Install a recovery (Preferably TWRP because I forget how CWM's adb sideload works). For TWRP, go to advanced, then adb sideload. Make sure to install the adb drivers tho, or else the sideload won't work. If you're sticking with stock, press the Vol+ button for about 15 secs, then tap the power button. Use the Vol- and + keys too scroll. There should be an option like "Install firmware through adb" or something. Scroll to that, then hit the power button to go to that option. Then, just sideload the firmware.
Check device manager 1st phone is conected properly
adb has no relation to fastboot.adb will not work while in fastboot, it never worked that way either.
There is no sideload while in fastboot, you're confusing it with the adb sideload, that has nothing to do with fastboot.
Reading and comprehension are desirable here.
I'm trying to flash TWRP on a nexus 5. Bootloader is already unlocked. USB debugging is enabled. The command "adb reboot-bootloader" works when the device is on. While in fastboot it does not say USB is connected and doesn't show up on adb devices. (My laptop is currently running Elementary OS)
As soon as you're in bootloader mode you have to use 'fastboot flash recovery recovery.img' adb is used when the device is powered on and in debugging mode - but it's not the right command for flashing [emoji14]

Yeah I know HOW to flash a recovery I already tried that exact command. Thanks for the suggestion though. The problem is that it just doesn't know its there.
Sent from my HTC One using XDA Free mobile app
While in bootloader mode (not recovery!) connect your phone and try "fastboot devices". What does it show? Post a screenshot of your command prompt.
Sorry its my friend's phone so I don't have it with me. I will have to get back to you on that
1. USB Debugging ONLY applies to ADB while booted into Android, NOT the bootloader or recovery
2. ADB is only used within Android (with USB Debugging enabled) and recovery, NOT the bootloader
3. Fastboot is whats used while in the bootloader, not ADB (use fastboot devices, not adb devices)
4. Some people find you may need to use 'sudo' for fastboot commands

First of all thank you for ur fast answer but i already do what you say.I wrote before my tablet stuck fastboot mode.When I write fastboot reboot code in cmd,tablet restart but still fastboot mode.
hi, im new in this android arena and this is my first time using smartphone so please forgive my noobness.
i want to root my phone Xiaomi Redmi 5A and i follow some tutorial on youtube where he told to use Minimal ADB & fastboot, TWRP, lazyflasher noverity and lastly Magisk.
im flashing my phone using this command on ADB:
fastboot devices
fastboot flash recovery twrp.img
fastboot reboot
i guess this is it so im rebooting my phone to get into twrp recovery mode by pressing volume up+power but it showed xiaomi stock recovery instead not twrp recovery.
so what i do wrong that i cannot get into twrp recovery menu?
please help me
Don't type fastboot reboot command after flashing, reboot to recovery manually

i type that command after the first try not working (without fastboot reboot command)
it still gave me the same problem even not typing fastboot reboot command
Is the TWRP flash successful?
Ensure that your mobile drivers are installed properly on your pc and that you've enabled USB debugging.
Now after connecting your device to the computer :
1)open adb
2)type adb devices, if it shows a serial number then proceed
3)adb reboot bootloader
4)fastboot flash recovery xxxx.img
After this, remove the USB and reboot to recovery by Holding the appropriate combination of keys.
If you reboot your device first, and then power off and reboot to recovery, you will still get stock recovery.
