The situation here I think is common, but I have not found any other content that could help me.
In short, the phone's display is broken, you can't see anything. But the touch works, as does the whole phone.
I would like to know if there is a way to control the phone from my PC. So that I can backup everything and buy a new phone.
Considering that I have available:
- adb and USB debugging: but not enabled on my PC. Basically I see the code of the connected phone but next to it it says "unauthorized".
- The phone has an initial unlocking PIN which I can't get past because I can't remember the position of the keys.
- I have Cerberus installed, which allows me to run shell commands, but only if I can unlock the display.
How can I solve this?
Thank you very much
Phone info:
- Model: Xiaomi K20 / Mi9T
- OS: Lineage OS 17.1
Get an image of the keypad positions and make a template. You'll need to do that for every page or popup you need to access.
Or...
Replace the display.
In the future backup critic data regularly to at least 2 hdds that are physically and electronically isolated from each other and the PC. Otherwise it's only a matter of time until something like this happens.
Install vlc player. Then put android to PC on you computer and click run both bat will display the screen on the computer. You can control the phone with the mouse on the computer and it will also play sound
Ok guys, I did solve my problem in the following:
Using this branch of Scrcpy I turned my PC into a OTG kb. So with the computer I inserted the PIN of the lock screen
Once unlocked the screen, i random clicked on the screen to authorize the PC with adb. It was easy since the popup will last over everything.
With the PC authorized, using scrcpy I was able to cast the screen of the phone on the PC and control the phone either
This way a backup was possible!
Thank you for your help

I've ran a backup in recovery mode and am trying to get the backup onto my laptop, in order to restore it to another phone.
The problem I'm having is that the phone is set to connect as a camera when connected via the USB cable, so iPhoto opens when I connect the phone. I actually need a file system browser to open, however the screen on the phone is cracked and it's no longer possible to navigate menu items using the screen, and so I can't change how the phone connects when plugged in via USB.
suggestions?
Cheers

This isn't going to help much (sorry )
but when I was trying to open the file explorer on my PC it wouldn't do it unless Debugging was turned off. And when it was turned on only the camera photo sharing option would work. So for me to get on my phones storage via PC, I had to turn debugging off. Idk if you have it on, but if that is the problem... hate to say it, but you're kinda ****ed. Hope someone will give u a useful answer :/
at least this comment will be a bump
I could be completely wrong though...
Hello,
I have a Galaxy S4 i9505 which boots up normaly but the screen is not starting at all. It felt down to the floor, and the screen is not starting.
I can here all sounds during boot up and if I press the Main button, I can see that back and menu buttons get litghed. Also can receive calls, etc... so it works fine.
At this point, I am not sure if touch screen is also damaged or not...
1. My first attempt was to use Kies. It detects the phone perfectly but it says I have to change connection to MTP. No way to do it as I cannot see anything on the screen.
2. Second attemp. I have bougth a microusb HUB to connect a HDMI cable to my TV and also a mouse, but my tv is not detecting any signal in the HDMI port. (usb powered as well).
3. USB debugging is not activated in the phone, so I think I cannot retrieve any data by using ADB.
I could copy all pictures to my pc, as when I connect the phone to my laptop, it detects multimedia files and I could copy.
Contacts are not sync with Google but stored in the phone, so is there any way to get all contacts somehow?
I hope you can help me.
Thanks
Javier
Without replacing the screen, there's no way I know of to get the contact information off the device, given that you already tried casting the screen to your television.
Hello!
My friend dropped his A9 down on the floor and obviously killed the display. It stays black all the time, but the phone is up and running. It has no kind of locks (PIN, pattern, ...) on it. Also, the phone has no custom recovery. We want to save his photos which are saved at the internal storage of the device (he didn´t use a micro-SDCard). This is what I´ve tried so far:
Connecting the phone via USB with the PC. It´s detected correctly, but there is no file system visible, obviously USB-mode is not set to MTP
Contacting the phone via adb. But unfortunately, USB-Debugging was never enabled on the device
Connecting the phone via Samsung´s Smart Switch. But I think, initiating this connection needs a confirmation on the phone - which I cannot enter.
I´m thinking about connecting the phone to a monitor via a USB-C-to-HDMI-cable, but I don´t know if this works with this phone. But even it does, I will not be able to enter anything. I´m also thinking of connecting a mouse via USB-C-to-USB-cable. Also, don´t know if this works, but even if it does, I cannot see what I enter with the mouse.
Any ideas how to gain access to the internal storage?
Hi,
My brothers phone screen is basically unusable.
When I connect the phone to the PC it recognises it in Windows but the phone contains no folders. At first I assumed it was because his screen was locked so I connected a OTG and keyboard and using commands managed to get his phone "unlocked" to the home screen.
However this didnt fix the issue.
Reading around it seems I may need USB Debugging enabled (if he hasn't already) but due to not being able to use the screen how would I do that?
Do I need a MICRO USB to HDMI & USB adapter to use a mouse and TV output?
Or is there a way I can fix this through windows using ADB?
At this point we are willing to try anything as all we are looking for is some family photos off of it then binning the phone and I don't want to put £100-200 into the screen replacement just to attempt this data recovery.
All help is greatly appreciated,
Cheers
ADB is the door to any Android device. As long as ADB has not been activated on the device - and the related RSA keys got created - you have no chance to pull out data from device, IMO.
Ok,
Well see the fact when I connect it to windows it shows the phone but not the folders inside, and I can only assume there will be a popup on the screen mentioning to ALLOW/DECLINE transfer etc..
If I use the OTG adapter I can plug my keyboard in and use the sequence SPACE, SPACE, BKSPACE, BKSPACE, then my PIN and ENTER and it unlocks to the home screen.
But because I would need the phone connected by both PC and KEYBOARD at the same time is it possible to get a splitter on the OTG adapter and this would hopefully let me press RIGHT and ENTER to accept the message?
If not then can the phone be connected via HDMI to see if any message is infact popping up??

OK, new to this. To get usb debugging on, click system. About phone, Software information, build number. Click that several times. (AT least 10). You will see a message that you are in developer mode. Go back to home screen. Click settings icon. Scroll to bottom you should now see { } Developers optiions. Click that. Find the section for ADB, enable ADB. Once ADB is up and running you should be able to pull the files. The screen for an android is the desktop, mouse, and keyboard. (PC analogy). You need something to see your icons, something to click, and a keyboard. If OTG acts as a mouse, and you can see the basic display, and have an external keyboard. I think you can do this. I am not sure what OTG is .

1. I cant follow that process as the screen is completely destroyed (no display/no touch), thats why I have been blindly using a keyboard to try and find the setting
2. OTG is ON THE GO , its a small adapter that lets you connect USB devices to your phone.
Sorry about that. I think you are stuck. without some visual clues I think you can not put the phone in developer mode. Did you try just a plugin (via usb) into windows and seeing if there is a pictures folder?
It find the phone in Windows, but wont display the folders.
The OTG splitter I purchased to be able to connect it to the PC and KEYBOARD at same time didnt work as it doesnt supply power (should have checked reviews).
Any other solutions? Or is this a new screen for £200 just to get data?
I purchased another OTG splitter that has a OTG/CHARGE switch so this should let me connect it to the PC and KEYBOARD.
Can anyone give me shortcut keys or step by step on how many times I need to press certain buttons to get down to the USB DEBUGGING section please?
Hello.
I've got my mother's Samsung A20. And i need to recover data, but the screen doesn't work.
When power button is pressed, display flashes the lock screen (wallpaper, current time and so on). And then it turns black (backlight stays on for 30 seconds, and then turns off). Pressing the button doesn't guarantee flashing the display, sometimes it goes black immediately. Touch screen gives no input as far as i know (can't hear anything when trying to type pin). Problem still occurs during and after reboots.
I managed to connect a mouse and keyboard with USB OTG, and i was able to unlock. But the phone has no MHL support, so i can't get any image through USB. I'd try pressing the power button repeatedly to get some image and inch my way through the interface, but the lockscreen interferes.
The USB port is set to Charging Only mode, so i can't copy files to my computer. USB Debugging is disabled, bootloader is locked.
Does anybody have a clue, how to get image? Some way to get data? Maybe some keyboard shortcuts, so i can disable lockscreen and make my way easier? And maybe disable 20 alarms in the morning?

I like to be helpful so I'll try to give you some suggestions but I hope others pitch in who know far more than I do.
I never use the USB cable anymore to operate my phone from my PC (but my screen isn't broken so your situation will be much harder).
I connect to my phone from Windows over Wi-Fi without USB all the time, and I can unlock my screen from the PC, and I can mount my entire Android device as a drive letter on Windows over Wi-Fi, etc., so "maybe" (just maybe though), you can consider using either a WebDav server on Android to access your files and/or adb to bring up and manipulate activities on Android....

However, I don't know if adb will work for you if you can't turn on USB debugging in the first place... but as of Android 12, adb now works completely over Wi-Fi (see screenshots below) without needing the USB cable to establish the initial connection like it used to be prior to Android 12.

If the screen problem is "just" hardware and not software, and if you can turn on Wireless Debugging, you might be able to display your phone over scrcpy or vysor (both of which use adb over Wi-Fi) as shown in the screenshots below on my phone - which never needs the USB cable connection.
Hope this helps, but you seem to need folks who know more than I do as adb/vysor/scrcpy all work for me because I can set up USB Debugging & Wireless Debugging as shown below.
Note that you might have an FTP server or a WebDav Server on your Android phone, and if you do, you might be able to at least transfer important files since they each can mount your entire Android phone as a drive letter on Windows over Wi-Fi (without needing the USB cable).

A20 can have only Android 9, 10 or 11, but thanks for ideas anyway.
I didn't even know adb can work over WiFi, I'll look into it. Hopefully this version can do it too.
Now trying blindly to turn on the screen reader…

Ooops. My bad. I apologize. You'll need the USB cable in Android 11 for a moment to establish the connection first. Then you can switch over to Wi-Fi after that (or you can stay on USB).

I feel for you. I really do. It hurts me when people can't access their phone remotely to get their data back. I am searching all over the XDA site for a solution for you, where I just moments ago opened this thread to help (I'm still searching for you though).
What is the best XDA solution to control Android on the PC & recover data over Wi-Fi when the user suddenly has an unresponsive broken screen?
