I am trying to access my phone through ADB to register w/o data. My device center and device manager both see the phone ("Android Phone" in DC, and "ADB Interface > HTC Dream" in DM). However, when I run ADB from the command line it cannot find my device. I have tried reinstalling drivers, killing and starting the ADB server, and even re-flashing my phone.
Note: When booting the phone from a fresh flash I DON'T have to enter "<enter>setprop persist.service.adb.enable 1<enter>" to initialize ADB. It is automatically seen as an ADB device, and after entering the command it is only seen as a storage device.
Thanks in advance.

Solved it by installing the drivers from here: http://www.mydigitallife.info/2009/08/24/workaround-for-htc-hero-sync-problem-in-windows-7/
Hi,
need some help with fastboot.
Entering "./fastboot devices" gives no results.
Streak waits with white screen and displays FASTBOOT_MODE.
I did not install the SDK, but took the adb tool from the current SDK.
Entering "./adb devices" list one device - works!
I noticed that it is important to use the adb from the current SDK currently adb version 1.0.26 (an old adb version 1.0.25 did not work).
Streak with Stock Froyo
Linux / Ubuntu 10.04
Streak is recognized as (lsub): Bus 001 Device 011: ID 413c:b007 Dell Computer Corp.
Any idea? Are there different fastboot-binaries out there? All the ones I have found are 127435 bytes.
Thanks a lot

I have exactly the same problem on ubuntu 10.04 with standard 2.2 Froyo.
adb devices shows the Streak but fastboot devices shows nothing. I have played with this for a while without success. I would love to have this working any help would be appreciated. I am using android-sdk-r07-linux_x86.tgz and fastboot 130.4 kb.
The streak is detected on USB and I can turn on and access USB storage.
Solved
Just found out, "./fastboot devices" simply does not work - unfortunate.
But try "sudo ./fastboot -i 0x413c reboot" - this will show "rebooting..." and actually reboot the device. Must be with sudo.
That means fastboot works.
I suppose, no need to install the SDK, no need to put any rules files into /etc/udev/rules.d

Hi,
I'm trying to repair a friend's Iconia A500 which is stuck on ACER logo.
My friend doesn't know the Android version of this tablet.
My tests have been done under Windows 7 64 and XP Pro, no antivirus, no firewall, UAC disabled on Win7 (always in run as admin mode).
All boot tricks have been tested (wipe / reset / hard reset... : power / vol - / vol+ / lock button...)
I tried to update with following files (renamed / extracted / decrypted if needed) on a FAT32 micro SD card :

I tried official Android drivers (adt-bundle-windows-x86_64-20131030) and others from another ZIP (root-3.2.1-V4) :
recognized as "Acer Picasso USB Boot-recovery driver".
I modified the .inf in each driver package to re-install the driver in each possible mode in order to obtain the following device name :
Android Bootloader Interface
Acer Composite ADB Interface
ADB Interface
Still unable to display my device via "adb devices"...
Any idea ?
I saw on internet that I can do screen recording from phone, but i need to run a command via adb, and adb doesn't recognize my LG G2(D802)..i had installed the correct usb driver from lg site
When i open ADB and type: adb devices, it says "List of devices attached" and no name of device appears
PS: developer mode is enabled
EDIT: i managed with that..but now says that the device is offline what means that?
Hi everyone,
I have a Nexus 6P which simply refuses to connect via USB on my Mac (i.e. it doesn't show up as a valid device under adb devices or via Android File Transfer). I believe it was working at some point but it seems to have stopped now. Might be worth noting, I did try connecting it to my car's charger a few months ago but had the worst time with it, it would charge and disconnect every few seconds (may or may not be relevant in this case as it pertains to the USB). I tried a different charger and it works fine with it though.
I have tried a lot of different things (which I'll list below) but have had no luck getting my Nexus 6P being recognized as a device when I connect it to my Mac (or any other). I do have the Developer settings enabled and I am able to switch to MTP but I never get the prompt to change USB mode. Anytime I connect my device, adb devices doesn't list it at all. I tried ADB File transfer as well and that also says "Please connect your device".
Here are some of the things I have tried so far:
1. Used different cables - no luck
2. Used a different mac - no luck
3. Tried a different Nexus 6P with my cable, it works fine (so it is not a cable issue)
4. Tried a different Nexus 6P with my mac, it works fine (so my Mac seems to be OK too)
5. Restarted in recovery mode - no luck
6. Tried removing a bunch of apps in case there was something conflicting - no luck so far
7. Chatted up Google support - They couldn't tell me much outside of the last option - Factory Reset - I have been holding off on that since I want to be able to transfer my files out first but I really want to avoid having to try that before exhausting all other options. They did offer to replace with a refurb'ed device but I had to decline that.
I did create a bug report dump using the device to see if anything interesting showed up and the only thing noticeable there is an exception related to USB. I am putting that info here in case it is useful in helping with this.

Are you on a custom rom? Do you get an authorization prompt if you call "adb device" after doing "Revoke USB debugging authorizations" from Develop options?

I wasn't connected to my Mac at the time I pulled the report (I confirmed by repeating it just now and still get that 'FileNotFoundException" in the logs for USB device. I don't have a custom rom, I have the standard OEM from the Google Store and didn't do anything else with it.
Also, I did revoke the USB debugging auth multiple times and inspite of that I never get any prompt when I connect.
I also got the report while connected to the Mac and am still seeing the same exception:

I usually only get the key prompt for ADB authorzation when I connect my device and type "adb devices"..... If worse comes to worse, You can restore your phone to factory settings without wiping your sd card. Then you could test that option with compromising your data. Just flash each image from the archive yourself when restoring the firmware as opposed to using the flash-all scipt, or resetting the phone from settings... DO NOT flash the "userdata.img" included in the factory firmware archive or issue the command "fastboot format userdata" during the restore process and all of your files will be fine. This may be an option as long as fastboot is still functional on your device. Ive come across so many different devices in so many different conditions over the years, as long as the device could power on and the usb port was functional, fasboot has worked time and time again.
PS adb on Mac can be a bit tricky especially if this is the first time youre attempting to o install and use it. Unless you set the correct enviornment variables during the install process, you will oly be able to access adb from inside the folder that its stored in on your mac. Youll have to pull up your terminal and and direct it to the folder containing adb and fastboot. Its usually ina a folder called "platform-tools" Which can be found in the dictory in whch you installed the Android SDK or SDK Tools packages... Now that I think about it, you have to download adb from the SDK package I just mentioned. After doing so, youll find the platform tools folder and it should contain what you need. As long as java is correctly installed on your mac then everything should work once you issue the "adb devices" command in a terminal session thats points at the "platform-tools" folder. YOU ALSO HAVE TO HAVE JDK INSTALLED in order for it to work with your device. I just looked at what you posted and it looks like youred missing JDK"...
If you havent done any of this yet the thats the problem. If everything I just typed seems confusing then you can try this which explains everything you need to do to set up adb a whole lot better than my attempt above lol buts its going to take some time to accomplish https://seo-michael.co.uk/how-to-setup-adb-on-os-x/
or
You can also install and configure adb a whole lot easier by issuing the following commands from within your mac terminal.... (This will install Brew on your Mac, if you arent familiar with what it is, Its a software distrobution platform. Sort of like git hub and linux software repos. When in doubt, do a little reading first. It'll solve all your problems....
-Install Brew - Copy and paste this command into a mac terminal and follow the prompts that show up.
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
-Once that finishes, next use this command
brew update && brew cask install java
-Once that is complete enter this last command
brew install android-platform-tools
Those 3 commands will do 99 percent of the work. When its done just find the platform tools folder and go from there. Hope this helps.

He says he already tried adb devices which didn't list anything. That tells me adb is configured correctly. Otherwise it should've given errors. Plus, he also said another Nexus 6P worked on the same mac.

Thanks for the detailed steps but like adotkdotjh mentioned, I already have a working adb (and it worked fine with a different Nexus 6P on the same mac). How would 'fastboot' work if the computer does not even see my device under list of devices? I've never done any image flashing before so that would be quite an unfamiliar territory but I'd be willing to explore. Where would I get these image files and how do I issue the command to the device while it is not being recognized? Thanks

Fastboot (also refered to as "download mode") is a tool used to essentially reprogram your device in the event that you are unable to enter into recovery mode in oreder to fix whatever issue your device is having. Android devices have 3 working modes, normal function, recovery mode, and fastboot. Number one is obvious, recovery allows you to completely reset your device without using a computer if every other measure youve tried hasn't worked. When you use this feature everything on your device is erased and your phone is completely restored to factory settings. Its convienet becuase not everyone is computer savvy and its to the point. But say you were updating (system update) your phone and accidently dropped it causing the battery to fall out and the device to shut off in the middle of the update process. What will most likely happen is the system partition will become corrupt, causing the phone to stick at the initial boot screen. Usually if that happens you can still access recovery mode and just reset but if for some reason that didnt work you would go to the manufacturers website and download the latest firmware for your device. You put the phone into fastboot mode by holding volume down and then pressing and holding the power button at the same time (while the phone is off).The process varies bydevice, If done correctly you will see on your screen a bunch of info along with Andy (the Android) chillin with his hatch open. You connect your phone to your computer and as long as your computer is set up correctly with adb and fastboot, you now have the abailty to reprogram (flash) your device using a series of commands that are issued from either the command line (windows) or terminal (linux/mac).
YOUR BOOTLOADER NEEDS TO BE UNLOCKED BEFORE CONTINUING. IF YOU DONT SEE A LITTLE LOCK AT THE BOTTOM OF YOUR DEVICE UNDER THE GOOGLE LOGO WHEN YOU FIRST TURN IT ON THEN YOU NEED TO GO TO SETTINGS, ABOUT DEVICE, FIND BUILD NUMBER AND TAP IT RAPIDLY UNTIL YOU SEE A MESSAGE POP UP SAYING YOU UNLOCKED DEVELOPER OPTIONS. GO BACK TO THE SETTINGS MENU AND SELEC DEVELOPER OPTIONS WHICH SHOULD NOW BE THERE AND INSIDE THERES AN OPTION CALLED "ALLOW OEM UNLOCKING" TURN IT ON. AND CONTINUE
Eextract the firmware archive you downloaded which will produce a folder containing 2 ".img files" files, another ".tar" archive, and some script files that you can use to make the process pretty much automated.
There are two of them, one for Windows (flash-all.bat) and one for Linux and Mac (flash-all.sh)....
Open the folder that was extracted from the firmware archive... Hold shift then right click a blank area in the folder. Select "open command prompt here" (Windows)
or
Type in terminal : cd ~/downloads/xxx where "xxx" is the name of the folder that was extracted but make sure that folder is moved to your "downloads" directory first
Then type the following commands:
IF YOU HAVENT UNLOCkED YOUR BOOTLOADER BEFORE THEN THIS IS WHERE YOU WILL NEED TO:
For Mac/Linux type: ./fastboot flashing unlock **Make sure you use the ./ or the command wont be recognized**
For Windows type: fastboot flashing unlock
Select yes on the phone when it asks if youre sure..... BAM, unlocked bootloader.
Your phone is completely free of restrections if you want to install custom firmware now. If not you can relock it after flashing the stock firmare by enterning fastboot mode again and typing
fastboot flashing lock or ./fastboot flashing lock (mac/linux).....
Now we can proceed with flashing the device...
For Windows: flash-all.bat and hit enter. The computer will do the rest.
Linux/Mac: ./flash-all.sh Make sure you use the ./ or the command wont be recognized.
If youre feeling brave you can do the entire process yourself by extracting the files in that second archive that was produced and flash each of them individually using a series of command in a specific order.
The 2nd extracted archive will give you a folder with five .img files
boot.img
cache.img
system.img
recovery.img
userdata.img ***** DO NOT FLASH THIS IMAGE. FORGET ITS EVEN THERE****
Take all five and move them to the original folder that was extracted. There are 2 other .img files that were extracted from the first archive also like I mentioned above, one that says "BOOTLOADER.xxx.xx.img" and one that says "RADIO.xxx.xxx.img"... Rename RADIO.xxx.xxx.img to | radio.img |and the other to| bootloader.img |ALL LOWER CASE keep them in that folder along with the other five. Now you should have 7 total image files in one folder. (Its smart to use the folder that your command prompt or terminal was opened in, if you decide to use a different folder then you have to direct each fastboot command to the folder where the .img file is located.
from the command line you flash each img individually with the following commands.....
(Mac/Linux need to include ./ before every fastboot command begins like this: ./fastboot or it wont work.
fastboot flash bootloader bootloader.img
fastboot reboot-bootloader (phone will reboot then go back into fastboot mode, dont worry should only take seconds)
fastboot flash radio radio.img
fastboot reboot-bootloader (reboots again)
fastboot flash boot boot.img
fastboot erase cache
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot format userdata (this command takes place of the "userdata.img" file I told you to forget about)
fastboot reboot
As long as you see action on the screen and a "complete" after every command then youre in business. If you get an error check your spelling. THE COMMAND LINE IS CASE SENSETIVE. You might type the correct words but if one letter is capital the command wont work. If theres an extra space between words then the command wont work so check everything. Safe rule: Everything should be in lower case letters with 1 space after every word.... THIS S*** MATTERS
Its not as hard as it seems if you arent familiar with the process, but its also not something to mess with unless youve done your homework. Read up on it, there are so many good posts and people in here so you'll be able to find everything you need without any issue.
Fastboot can also be used to install a custom recovery like TWRP which would then allow you to install custom firmware (roms) on your device as long as theres support for it. Nexus devices are built for that very reason! They tend to have a huge selection of development within the Android community. They come with Android as Google intended it to be! No extra BS.... And its wicked easy to unlock the bootloader. That is why they are, in my opinion, the best Android devices available. But someone who doesnt really care much for things like modding and installing custom firmware might see the Nexus as plain device which lacks the bells and whistles included in other devices. Which is ok! I personally love the simplicity of pure Android and the whole philosophy behind the Nexus Program. To each is own! If you need anything else send me a message!
Have not read it all on here lol install this on your Mac https://www.android.com/filetransfer/ and see if it sees you 6p make sure you plug in them change from charging to file transfer on the phone then exit out of the app and reboot that will tell you if your Mac sees your phone
