If you enter the fastboot screen and keep scrolling you will find an option called "early usb enumeration".
Can someone explain me what it is useful for or what it does?
This should give you some insight

Does "early usb enumeration" give adb access even if usb debugging is off? This is what I really wanted to know.

Hi my atrix 4g is running the stock rom 2.3.4 beta4 from kenne. And I found out that when I connect the atrix 4g to my laptop, it didn't go USB debugging mode, as I did switch on the USB debugging on the atrix.
Can someone give me a hand on this?
How did you determine it didn't go into debugging mode? Are any devices listed if you do "adb devices"? Did you confirm that debugging is enabled (settings->Applications->Development)?
Yes it didn't go to the debugging mode. I didn't try that. Yes I can confirm I enabled the debugging

What did you expect to see? When you enable USB debugging it basically means that you can access the device using adb via a USB cable. Just connecting a cable does really change the look of the display, other than in the notification bar, the debugging icon will appear.
Have you tried connecting your Atrix to your laptop while in "Mass Storage" mode? Does that work?
I expect a debugging icon on the notifications bar.
I took some screen shot with the phone

I never noticed that the icon doesn't show up on my notification bar. However, if I do "adb devices" from either my Win7 PC or Ubuntu system, it displays my device. Further, I can do "adb shell" and access the phone.
Therefore, I'm guessing your phone is in debugging mode and the icon is not being displayed.
I have just confirmed that the icon is not displayed on my Cherry Pi (0.4) or a stock AT&T build.
Hello all,
I purchased this phone a month back and would like to install custom roms/root it etc.
I am unable to get my phone to enable USB debugging and allow access for my PC. (I have a unlocked bootloader). The notification (prompt) for USB Debugging which shows up the phone (asking if one wants to grant access or not) doesn't show up. Hence I am unable to use adb or fastboot to install TWRP.
I have tried using the cable provided by the company on both USB 3.0 & 2.0 ports to no avail.
I am aware that there is a "How to Guide" under the News/Discussions section. However, it hasn't helped me much.
Any possible solutions?
Thank you
PS- When I connect to pc using USB cable I get the prompt asking me if I want to use it for file transfer,PTP or no data transfer.
Are the drivers properly installed?
What does the device manager show, when your phone is connected via USB and USB debugging is switched on?
What happen if you type "adb shell" when your phone is connected?
Enable it in developer option
Allow USB debugging and USB debugging Security Settings) in Developer Options

@YoYo178
On PC run
Code:
fastboot devices
to check for a valid connection. If phone is connected via USB with PC run
Code:
fastboot reboot
to leave fastboot mode ( means re-start phone normally )
Afterwards run
Code:
adb devices
to check for an established connection. If a connection got successfully established
then you force phone to run in adb-mode
Code:
adb shell "svc usb setFunctions adb"
adb reboot
Now you should be able to recover phone's user data. For example
Code:
adb pull /sdcard/DCIM %TEMP%
Code:
fastboot devices
yes it shows, done.
Code:
fastboot reboot
yes it reboots too.
Code:
adb devices
nah nothing shows in adb devices (USB Debugging Isn't Enabled)
And I Do Not Want To Recover Data, I Want To Mirror Its Screen. Well, There Is A Lil Bit Of Data Too.
I Want To Enable USB Debugging And
Code:
push adb_keys
file Which i got From A Authorised Device.
@YoYo178
You can't enable USB debugging by means of ADB: Having USB debugging enabled is THE requirement to make use of ADB.

Hi there, I had the exact same problem with my moto e 2nd Gen LTE (surnia). First of all this isn't a software issue, it's a hardware one ! Displays on some of those phones were faulty and I had to take it to repair it (just to clarify).
I had an immense chance because just before that I installed a screen mirroring app. I opened it through Google now (it was 6 years ago lol) and blind clicked because I remembered the layout of the app.
If you didn't have that chance you can try with USB OTG cable to HDMI port, and connect your phone to a PC with an HDMI cable. I didn't tried that on mine, so idk if HDMI through OTG works. Good luck with that :good:

Sorry to hear it doesn't have OTG, I won't be able to help any further as I'm not experimented enough in that field, hope someone else will do tho.
Have a nice day anyway
Hi
Have honor 8 Pro. Screen broken and no display but phone is on only.
Need to take backup.
Adb don't show devices. Can't accept USB debugger
External display via type also don't work.
Mtp is not getting enabled when connect cable
@madroamer
I guess you'll not have any luck, this because USB mode ADB is basically the door to any Android device. Also take note that MTP only works if this USB mode got enabled on Android device.

If your bootloader is unlocked it might help, but this case smells like secure startup and I don't know if is it possible to bypass it by changing the boot, system, etc - whatever...
Used the USB-C to USB adapter from computer and connected a mouse to your phone. When the lock screen of your phone appeared, pit the code to unlock the screen. With this your will unlock the phone and turn on USB sharing.
So i forgot the PIN number on my old phone which was not rooted, had no recovery software (Cwm, Xrec, etc.) installed on it, and has usb debugging and auto-mount disabled. We don't know the google account associated with the phone. Basically all I have is the phone and a usb cable. Is there a way to get the user data out of it? Adb won't recognise the device btw. I do apologise if it's a stupid question. The phone automatically connected to the wifi, and I'm on Linux, if that helps. But I managed to get into recovery but adb only recognises the device in sideload mode. The files inside the phone is extremely important to me because it contain photo of my family member that were passed away.
Phone: Vivo V7 Plus
I wanted to try brute-force the PIN with program but unfortuntely the phone will cool down for 7000 second (3hours+)
A phone typically knows of 2 USB modes: ADB & MTP. If MTP mode was enabled and phone supports a USB-C connection then it should be possible to fetch the user-data you're interested in.

Hi, first of all thanks for your respond. In order to enable MTP i need to have the phone unlock right? how can i enable MTP if the phone is locked ?
All I know is that ADB is the door to any Android device and nothing than that.
