Remove lock or enable usb debugging on non-rooted phone (Read data inside a locked phone)? - Android Q&A, Help & Troubleshooting

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.

[Q] Backup Phone, Enable USB Debug on Samsung Galaxy S3 that has a broken screen

Hi,
I was wondering if anyone can help with my poorly phone?
My phone broke a couple of days ago and the screen is black and digitizer has broken therefore I’m unable to use it. I don’t think there is any point trying to get the screen fixed but it will cost as much as a new phone would. But what I would like to do is backup the data on my phone.
I have not got USB Debugging enabled and when I connect my phone to the PC, the drivers are installed and I see my phone as a portable media device but there are no files or drives to display the phones data through windows explorer! Please help!?
After some research on the internet I have downloaded [email protected] and ADB.exe but the phone is not recognised (I believe this is because USB Debugging is not enabled).
I then did some further investigation and managed to book my phone under fastboot in recovery mode and selected ADB mode, this connects to my PC and new driver is installed but I am now not sure how I can use this mode to backup my device? And enable USB debugging so I can use my phone on [email protected]
Anyone able to help?
Thanks
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

Same problem :crying:

Unable to enter USB debugging 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

But I Cannot Please Help!!
@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:

Screen broken and no diaplay

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.

Rooting the G8 Power via OTG (without app, or PC)

Hi,
I'm currently interested in the question, if I can root my device without any PC or an app, because I momentarily don't own an PC, apps are mostly not able to root the device and interrupt in the middle of the process.
So shortly said, I have an Lenovo Tab M10 FHD+ and want to connect it to my Motorola, to enable root permissions on the Motorola phone with the app linked down below.
The only problem is, that I already connected it via OTG, but commands like reboot work, I was actually surprised, but as soon as I start going into fastboot mode, the device detects the phone, but not the app and no data transfer between the devices is being enabled.
- USB Debugging option in the developer options was enabled during the process
- OEM Bootloader Unlock option was also enabled
I even tried wireless debugging over WLAN, but problems like an endless loop while connecting, occured.
Can anyone help me getting the right commands for the app?
Link of the ADB OTG shell app, I'm using:
ADB⚡OTG - Android Debug Bridge - Apps on Google Play
⚡ Run ADB commands without a computer [No Need ROOT] ⚡
play.google.com
Have you fully unlocked the bootloader?
