display and touchscreen dead, no usb debugg : solution for this issue.

morning geeks
you have a phone, which is not able to :
show the display
use the touchscreen
but the hardware is still able of these features :
usb mtp device, as a usb key
wifi network
cell network
and so on..
so you are here, somebody gave you a smartphone, running android, locked, but you can't neither see display or use touchscreen;
but its starting anyway, you can hear the ringer if you call on it;
how would you do, without usb debugging enabled, to use this electronic technology as a specific usage, like a wifi AP or a usb key?
in an other words, what is the method to restore it and to take the control of it?
you just have a usb mouse can be connected on it. but no display.
[this is mainly destinated to avoid throwing several android hardware to bin, cause it can still poweron.]

Unable to connect to PC in any mode

Hi all, I'm afraid I already know the answer to my question but I'll still ask if there's even a slight chance to get this fixed on my own.
I had this issue on Android 8.1 where my Pixel kept saying "Supplying power to connected device via USB" even without anything connected to it, (it started doing that one day without any reason) tapping the notification allowed me to switch to "Charge this device" and then turn on MTP mode, battery life was terrible but I wasn't that much bothered by it because I am an Android developer so I kept it connected in USB Debugging mode most of the time anyway.
When I got the notification for Android 9 update I decided to update hoping it'd fix the USB issue but after the update it now always says "Charging connected device" and tapping the notification does bring up the "USB Preference" screen and it allows me to switch to "USB Controlled by this device" and it starts charging but there's no way to switch "Charge only" mode to anything else, ADB does not see it, fastboot does not see it and there's no persistent notification on the phone about it being connected via USB at this point (in any mode). My understanding is that this is a hardware issue but Oreo still allowed me to workaround this and get the USB debugging connected.
Is there anyway I can get back to Oreo without using fastboot flash or any other solution to this?
Thanks for reading.
PS. I'm on Ubuntu but I can access a Windows machine if required and bootloader is already unlocked.

I'm curious if you're able to connect to a USB OTG storage device.

I'm having this issue connecting it to my windows 10 laptop.. the cable recognizes it.. starts charging.. shows option on phone to change type of connection.. but not matter which one i change it too, the computer will not pull lit up as a drive to see the files..

Same here! I plug the cable into the Windows 10 computer, I even can change the mode from charging to MTP file transfer, but the device won't show up in the Windows Explorer. It appears under connected devices though.

My Pixel 2 XL would not connect to PC for file browsing if USB debugging of Android Apps was enabled in developer settings. Didn't matter which option I chose to connect. IDK if that is expected or not, but it took me a while to figure out. Happened Spring 2018, idk if Google fixed it.

I don't think i've tried to turn that mode off.. i'm so used to needing it on for the computer to recognize and connect to all my previous Android Devices.. thanks for the recommendation...

Couldn't find any OTG cable to try that but strangely enough a few days back I connected it to PC for charging and Nautilus popped up, same cable, same USB port and it started working all of sudden. Did verify with a couple of other cables and different ports and everything is working fine since.
"Charging connected device" notification never appeared again, only thing different (when it started working again) was that I was out of the air conditioned room most of those days, might it be moisture or something like that?
I'm back to my normal routine for a few days now and it's still 100% normal, will have to see if it stays that way.
Sorry for late response.

Here's an update in case someone else runs into this situation, I can say this with 99% certainty that is caused by the blackish residue build-up around the USB port over time. It's not too much that it's visible just by looking into the port but it's enough to make the device behave like this.
Here's what I did to get rid of it, took a match stick (don't use anything metal) and broke it in half making a sharp edge on both broken pieces, took the non coated piece and inserted sharp edge in the bottom side of the port and gently wiggled it around while applying some pressure towards the connector (just a little bit, make sure you don't break anything), did this for about 45 seconds then took out the match stick and the part that was touching the connector had turned blackish (I guess this is when you know you have 'cleaned' it enough?), repeated the same process on the top side of the port with a new match stick piece (guess you can use the same one after cleaning it with a tissue), the only difference was that this time applied the pressure in opposite side (other side of connector), device was on during all this time.
It builds up again after a while (~3 months) so I had to repeat the entire process again when it started doing that again at the start of December but it wasn't that annoying this time because I knew exactly what was wrong and how to get rid of it, device is still working fine 100%.
I'm simply sharing my experience and not encouraging anyone to do this but if you do decide to try this be sure not to use anything metal and don't break the connector inside the port (turning the device off would be a good idea too) and you'll be fine and if something does go wrong I won't be responsible.

SOLVED: S7 dropped > broken screen > how to recover images? Not rooted,not "usb mode"

SOLVED: S7 dropped > broken screen > how to recover images? Not rooted,not "usb mode"
So my wife dropped S7 to the floor and device ended up to be fully powered, but screen is now all black. Back and "software" button illuminates. I can change volume. I can take photos. So phone works, but screen is all black. Main concern is to have photos out from the phone. Contacts are synced, software etc. can be installed to new phone.
Kies finds the phone, but says that is' locked. Although phone does not have any passcodes or fingerprint, Kies cannot access to photos. Also the PC does see the device, but it won't allow me to see the contents. Find My Mobile is not activated, I think that I can't activate it now without phone. Also Smart Switch says that phone is locked. Phone settings are pretty much as out from the box. USB debugging is off, Developper options off, etc...
But I found that possible via ABD (?) I could access phone storage. Is it so? I sould start the phone to Recovery Mode / Download Mode? How to do that? Normally the phone is on and I can't switch it off. I can only soft reset is by keeping vol- + power buttons pressed for 10sec. But after that, phone just restarts to OS.
Please give hints how to proceed. What to try. New LCD is around 50USD and takes forever to get from Aliexpress/Ebay.

Why not use an external display? Hook it up to the USB-connector via an adaptor and it should work to unlock the phone using a PC-mouse.

O, it has such feature? Quick googling did not help how to do it. How does it work? Do I need some cable or device?

Any ideas how to proceed? I either can reboot device to Recovery mode and use ADB or connect external display to the device. Or if someone has any better solution

Please help. Family photos are in the phone

Try to unlock your lock screen with a usb mouse connected via otg and swiping up with the mouse. Then connect it to the computer and try to backup your data with kies or switch.

Tried many thing how to allow the connection from another phone or computer. However it was not possible to connect, so I ordered a new screen. Once new screen installed, it was not even a challenge Ordered new screen from Aliexpress.

Urgent: need backup of A8 2018 with broken/black screen for upcoming court case.

I'm helping a friend who needs backup of her broken phone for an upcoming court case.
I need to extract all photos (camera, snapchat etc) and text messages (sms/mms).
The phone seems to be working other than the screen and touch controls.
Replacing/repairing the screen isn't an option as we both have minimal funds, and my friend has a new phone already)
i have "access" to the phone, but neither USB Debughing nor MTP is enabled so i cannot access any files.
I'm able to unlock it with a keyboard connected (i hear the little unlock click after entering the pin, and the "turn off screen" click when i press the power button.) But i have to navigate blindly, and any guide i find seems arbitrary how to get to settings, it says to press win+n (same as pulling down the quick settings menu from home) and press tab an arbitrary number of times to get to the settings gear in the corner. i tried doing this on my own working note 10 plus with the external keyboard, but i see it scrolls through every notification, so unless you know the number of notifications, hitting the gear is just pure luck.
I have also tried hooking up a usb-c to hdmi dongle (which works and starts dex on my n10+) but it says no signal on the A80, so external monitor seems out of the question.
Is there a consistent way to enter settings, or any way to enable the following settings:
* enable voice assistant (accessibility settings so i can hear where i am and navigate using voice/sound)
* enable USB MTP (or similar so i atleast can access files from a computer)
* enable USB debugging (to use ADB to screenmirror and/or etc)
* alternatively clear notifications so entering settings should become consistant with number of keypresses
I have tried some apps like dr fone but it doesnt support backup from this model, and any other settings wants to wipe the phone.
I have tried holding both volume buttons to enable google voice assist, but also unsure if this ever worked
The phone is not on wifi and i am not 100% sure if wifi is enabled at the moment, nor if it has the current wifi password my friend uses, but i can try do do things from there if internet access will help.
I dont think google now nor bixby (if this phone has that) is enabled as i dont get any reply or voice ding while pressing the win key (home button normally on working android)
I think i can enter recovery and download modes, i got COM5 on odin, but I'm unsure if i ever get into recovery menu.. but even then, is there any custom recovery firmware that will enable usb mtp access at all for this device?
Also, I'm not able to have a computer connected at the same time as a keyboard as I'm using a wired keyboard with OTG adapter.
Tl;dr:
Have:
* A80 with broken unresponsive screen.
* Have access blindly through otg keyboard
Need:
* Need to enable mtp and/or usb debug (alt. Voice assist)
* Need consistent way to access settings
Both MUST be done using only wired otg keyboard.
Tried:
* Hdmi out (no signal)
* computer recovery software (no dice)
* having computer and keyboard connected simultaneously (keyboard works, pc doesnt recognize, could be dongle)
Hope someone can help me (us) fast.

have you been able to verify that the MTP device actually works with other phones?
those things can be picky

USB MTP is just file tranfer?
F.ex. if i use smartswitch on pc, it first tells me to unlock the phone, if i unlock the phone with the otg keyboard and reconnect it it says i cannot tranfer files because MTP is not enabled in settings.

sorry man, i meant MHL adapter.

As far as i found out, A8 does not support MHL/HDMI out..
guess ill spend the weekend to try to get voice assist working by blind trail and error :/
If anyone could provide screenshots of the settings menu and/or recovery menu (and if its possible to enter without touching the screen, and if so how) that would be greatly appreciated.
The phone should be mostly completely stock set up, but home icons might have moved and menu icons might not be in the same place, but i think the pull down menu should be the same as any stock setup, so a screenshot of that would be nice too

Hi
As far as Android goes, by unlocking the phone and plugging it into a computer then you should be able to view the files on the phone from the PC like any USB drive. What you can also do is use Samsung Smart Switch and do a backup of the phone on a PC as this will be able to pull all text messages, photos, etc into a backup folder. Then you can restore any part of that backup on another Samsung phone, including messages.
There may be a few things that will not transfer over. As far as viewing the photos and other files, you can navigate to the backup folder on the PC and check everything there. This is all provided that the phone actually works and is unlocked.

As stated in my original post, usb-MTP (file transfer) is not enabled by default, and my friend never connected the phone to a computer, so i have to enable it to be able to access anything.
The phone connects and seems to work fine except the display, smart switch says to enable mtp pn the phone to transfer files after i unlock it, so my problem is activating talkback so i have aural navigation help so i can turn on usb/mtp for file transfer(and hopefully adb) or to turn on usb directly, but i think talckback is the highest priority as it will help me navigate the phone and be sure of where i am, an accidental keypress on can ruin a long sequence and i would have to start again from scratch as i cannot know if im in the same location.

Hi.
Any update on this? I have exactly the same problem and no solution so far...
Thanks

how to access phone with a broken screen?

I have a Oneplus 5 phone with a broken screen from about 4 years ago, the screen is entirely black and does not show anything, touch also does not work.
I want to mirror the device's screen to a monitor so I can set it up as an IP camera to record my cat giving birth.
I'm pretty sure I have usb debugging enabled since I last used it, so far I have tried:
1. connecting to a usb-c dock with HDMI to a monitor, but apparently Oneplus 5 does not support MHL.
2. tried using Vysor and Scrcpy, both work on my Galaxy Note 9 (main phone) but I have to unlock the phone and allow permissions to use ADB, since I don't have a working screen or touch on my Oneplus 5 this didn't go so well.
additional info that might be helpful:
I tried connecting the phone to a keyboard and entering the PIN (I'm pretty sure I remember it correctly) but I can't tell if it does anything.
the phone is functional, in fact, a tiny corner of the screen (bottom right) responds to touch and I can draw V gesture to turn on flash.
Vysor recognizes the phone, but upon clicking "view" it says: "The connected Android device requires pairing confirmation. click the "allow USB debugging" prompt on your android". but again, I don't have a working screen, and I cant have a keyboard connected to the phone and PC at the same time (unless there is a way I don't know of).
Is there any way I can get screen mirroring working on this device? it's been sitting in a drawer for 4 years waiting for this moment, I don't even care about recording my cat giving birth anymore... I just want this to work!
Any help is greatly appreciated.
