How to Reset/Erase screen lock PIN when USB Debugging "not" enabled, without loosing data?
After restart I couldn't enter the phone as it reported the PIN as incorrect. Earlier, I was using my finger print scanner and the phone was working fine.
I had not enabled the USB debugging and I am when I connect through ADB it identifies the device but shows the device as "unauthorized". So ADB commands and fastboot commands not working.
I tried some tools which use the "Preloader" driver but hasn't been able to connect the device through preloder COM port. It gets connected via Android ADB Composite interface.
Any ideas on how to how to Reset/Erase screen lock PIN when USB Debugging "not" enabled, without loosing data?

Hi,
Every time I restart my phone after enabling the USB debugging option under Developer options on my Moto E, the USB DEbugging option gets turned off. How can I keep it enabled.
I suspect that it doesn't let me perform adb devices and fastboot devices on my phone when I connect it via USB after restarting the phone in Fastboot mode.
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
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.
I forgot my PIN.
My screen's sensor is off (it acts up where I can't even enter guesses even if I knew my PIN.
Is there a way that I can use ADB to access the pictures and video from my phone? That's all I want to do.
I don't know if you can access files via ADB if the screen is locked, but it is possible to use ADB commands to unlock your device with your PIN. Here is a guide. This will only work if you already have USB Debugging enabled and your PC's ADB debug key is authorized on your device.

I doubt that USB Debugging is activated - at the time that I bought that phone, I don't know if I knew about ADB commands.
The PC that I am looking to use wasn't built at the time that I bought that phone either.
Does that mean I cannot use ADB commands to unlock my phone?

If USB debugging wasn't enabled and the PC wasn't authorized, then no.
