Pixel 2 non-functioning screen, options for using ADB? - Android Q&A, Help & Troubleshooting

Greetings fellow techno-wizards! Got a big problem that I'm hoping you can help me with.
Long story short, my trusty Pixel 2 had one too many drops, now the screen won't turn on and won't respond to touch. The logic board is operating, and I haven't rebooted since then, so I can unlock with the fingerprint sensor.
I plan on getting an Pixel 5 when it releases, and have an LTE Tablet to limp along until then.
My biggest problem is authenticators on my phone that I may or maynot have the backup QR code for, as well as many other things I'd like to get off the phone before I retire it.
I have the following things at my disposal:
Pixel 2, with USB Debugging turned on, and recently trusted the PC. No screen, no touchscreen.
WearOS watch paired to phone (can get notifications and texts)
Bluetooth Mouse
Wired mouse with USB to USB C adapter
Chromecast
Win PC with Scrcpy installed, already tried to use it to show the screen on the PC, I'm guessing its been too long and I have to press a notification to trust the PC.
The Goal:
To cast the screen to a chromecast and pair a bluetooth mouse, and/or get Scrcpy working by accepting the dialog that I can't see. This would allow me to use the migrate tool to the new phone I will eventually get.
I tried long ago to use a USB C to HDMI adapter, that doesn't work. Google wants you to use a Chromecast for such things (Thanks a ton Google )
The thing I need to figure out next is how to use ADB to force the phone to start casting to a Chromecast, or to remotely accept the dialog. The wired mouse with adapter should work to control the phone instead of the touchscreen, but without any video out, I'm clicking blindly. The microphones are working, but I've never tried to command the assistant to start casting before.
Can anyone suggest the next step I should try?

Just had a thought, there are accessibility features for blind people that would let them use the screen without seeing it. Is there any ADB command to enable these features? If I plug in a keyboard, is there a keystroke combination to turn them on?

Since you say ADB is enabled on the phone you should be able to pull out by means of ADB-driver the data in mind to your Windows computer.

Control your Android phone due to broken screen

Hi all
I just dropped my Nexus on the floor and the screen is crashed, as a result the touch function is not working as well.
It all came in sudden and I didn't back up anything, not even reading the unread message from those communication apps.
I wonder whether there is a way to project the phone screen on the computer and I can control it via my PC, at least I can read all the message and do the back up and say goodbye to my phone.
Many thanks
If the display (LCD) is still functioning, and it's a Nexus 5 or newer, you can use a USB OTG cable and a mouse to navigate around.

Broken Display, Flight mode on, No USB Debugging - Help

So I've been searching Google all day and still can't find a way around all this...
Phone (Nexus 5) got the black screen of death, where a connector on the motherboard gives up due to heat/old age. It only then works by applying pressure to the connection. The digitizer would sometimes play up and I'd have to press on the spot to write emails and texts. My phone got the the point where it became unusable and the digitizer started spazzing out, in that, the flight mode button got pushed, now the screen doesn't work at all.
So heres my dilemma..
Since I flashed Android 7.1 the USB debugging mode has never stayed on through a reboot and is currently off. That ruins my Vysor option to control the phone via usb. Theres a post about a guy who turned on USB debugging via Cerberus which I have, but with flight mode on that rules that out. I've managed to find my way into recovery and ADB works but I have plenty of issues, maybe because I had to use SUhide atc after 7.1 decided to clamp down on rooted devices with banking apps, snapchat etc. My Slimport hdmi adapter isn't working well but I guess thats a cheap fix and will allow me to at least see the screen, (no digitizer though). Other option is to use usb otg to connect a mouse and try things blind.
So are there any other ideas out there? ADB still may work, I got Boot.img onto my computer, but had trouble unpacking it.

Screen android phone broken, no USB debugging on, mouse working no visual

Hi guys,
My screen recently died. Before fixing it at a specialized shop, I want to retrieve the data from the phone. Sadly the phone is pattern-locked and until I unlock it I can't access the data when I connect it to my PC. The screen is essentially dead. The image is almost totally black except for small layer in left top corner and the touch sensor is unresponsive, but other than that the phone works and receives notifications and so on.
USB Debugging mode isn't active on the phone and thus I can't replicate the screen of the phone on my PC through software alone, when I connect it via micro-USB. I also didn't think of this problem in advance and I'm not registered on Sony's FindMyMobile or any similar apps.
I tried using a HDMI-MHL adapter and I confirmed that the phone is indeed working because I'm able to get the phone screen's image on my TV. The problem is I can't actually interact with the phone because as I said earlier the touch sensor is not working.
The HDMI-MHL adapter I've used also seems to have a micro-USB port but that seems to work for power only. If I connect a USB-OTG cable on it and connect a USB mouse to it I get image but no mouse. If I connect the USB-OTG and the mouse, alone, I get a mouse cursor but I can't see what I'm doing (phone vibrates as I 'try' and draw the unlock-pattern blindly).
So, Sony Xperia Z3 Compact screen is dead, I wanna connect my Xperia to my TV via HDMI AND use a mouse at the same time to control my phone. Is this possible_
I also thought of another option... go to recovery mode and flash a zip that removes lock. I thought of trying step by step (switch keyboard and TV al the time just to get at point where I can find zip file and flash it). Unfortunately in recovery mode the phone does not allow to stream to TV. It only works when phone is after SIM lock.
Two additions: by removing and re-installing ADB on my laptop my phone is unauthorized. Only a matter of clicking on yes/allow on phone but that's not possible and TWRP 3.1.1-0 is installed.
Anyone any clue? I know I ask a lot but I'm searching the internetz for 2 days now and I'm devistated.
THNX a great bunch!!!
ciao

PS Copy/paste a part of the text from a guy from the internet who had exactly the same problem as I did but his thread ended a few months ago without result.
Just 30 minutes after my post I magically had all the dots correct and that blind!!! So turned on USB debugging and got rid of lock pattern. It was a nice three days of my life Guess there was no solution than getting lucky like I did or screen replacement and getting all your data removed.
ciao

[FIX] Bootloop on MiTV Box 4k/S/2018

Try Method 2 only if you're sure your Remote has no problem and is connected properly. First is trying to determine the course of action. If you just bricked it. Then there's nothing you can do unless you take it to the care center or if you had adb enabled then you can force it into fast boot look after connecting it to your pc. That will be in another post. For now troubleshooting it is our concern.
So you have tried to use the TV Box and you can't force it to go into recovery mode neither have you had any luck with the usb stick update.
Method 1:
The problem is Mi TV Box won't boot and will infinitely boot loop unless the paired remote is connected. So most likely the boot loop is caused as the remote and tv box isn't communicating. Your remote may either be damaged or need a change of batteries or may have been unpaired/disconnected after the update.
So grab a USB mouse or USB Keyboard. Try mouse click and there will be a blank screen. Wait for 5-10 minutes. It takes time to load or is simply slower when disconnected from the remote.
Some keyboards don't work. But if they do, keep pressing either Esc or Enter till the Bootloop ends and brings you to a blank screen. Be patient and use a mouse/keyboard arrow keys to navigate to settings and Remote & Accessories. Then select Xiaomi RC and click on Unpair. The Battery % will be shown if it was connected properly. So then re-pair the remote and then restart. You can restart by holding the power button till the power menu pops up. That's it and that's all. Be careful since both Mi TV and Mi TV Boxes will not make it past the boot screen unless the paired or stock remote is connected properly. You can't find a totally working replacement/spare remote since the remote and the tv box are one unit and if either is damaged or has a manufacturing defect, it can't be easily replaced. As both have sort of link. So suppose you buy two Mi TV 4K Boxes and use both at the same time. The remotes will pair up and be forever linked to one particular at the time of set up. You can't randomly change it after that. Exceptions are always there but this is the case for the most part. Or so I believe it to be.
Method 2: If the above method didn't fix it. The issue is software related. You may need to perform a hard reset using either the recovery or get a keyboard with the same or equivalent combination of keys you'll use on the remote. Considering the remote not working or unable to boot into recovery using the remote. If possible get two people to do the recovery sequence on the remote. Since the remote is good quality and sensitivity for button press. Then load up the stable or latest beta update available onto a pen drive. Make sure that the update package is renamed to update.zip. Before installing Wipe/Reset All Data and it'll ask for confirmation. Confirm it and then proceed to install update.zip. The Pen Drive used may also result in success or failure. So use a reliable know good USB 3.0/2.0 stick. SanDisk gave me issues. I had to re-install thrice to get it to work properly. Also don't use sizes above 16 GB. Upto 32 GB is supported. And it may support external harddisk drives but the format is to be kept in mind. Any pendrive larger than 32 GB comes out of the box with either NTFS or exFAT File System Format. So check that before you put the update on it.

Note 8 Black Screen Data Recovery

Hi there XDA. Been a while and hope everyone's been fine. Need some expert help and hopefully some resolution can be found.
I have a Note 8 that was dropped. Belongs to a family member and was taken to me as the resident tech to get things off. I managed to get all FILES copied off the device, and they no longer need it however...being how I am, I'd like to try and recover EVERYTHING from the device. All notes and such - especially as some of these things were used for classes. However I'm stuck,
Screen is totally black and was responding to finger touches before - not doing so now. Unlocking the device isn't an issue as I can do that using the stylus or a USB keyboard through OTG. I'm able to navigate using the USB keyboard and get into certain settings, but without actually seeing what's going on I don't know what is stopping certain actions or why they don't work.
The current goal is to get talkback working so that it can read to me the various options. If I can get it on then I assume there will be smoother navigation - however....
I got my hands on a Note 9 and used two USB keyboards with OTG simultaneously to try and mirror the actions. Attempts to enable talkback failed. On the Note 9 the option comes up and you hear when it asks to be enabled, but on the damaged phone you never hear it. This is a tedious process which involves:
Attaching USB keyboard.
Using shortcut keys to get into the apps menu (ALT+A).
Navigating to SETTINGS.
Typing in the name of the area I need to get to.
Pressing the arrow keys the appropriate number of times.
etc. etc. etc.
Finally when it SHOULD be at the talkback option, nothing is read back to suggest it's enabled. Holding the VOL+/- keys for 3 seconds don't work. Inserting a SIM with data then using voice to "turn on talkback" results in a response: "I can't change talkback yet."
So now - I'm at a loss. Once I'm able to turn on USB debugging I should be able to connect to my PC/laptop and mirror the screen. From there all navigation should be easy - but following what is seen on the Note 9, it doesn't work. So I can't enable talkback and I can't enable USB debugging. I'm also not 100% sure where on the screen the prompt would appear - so unplugging and replugging then guestimate tapping have not been successful.
So far I can use it like an expensive USB drive, but I'd like to get all things off, test the functionality otherwise, and then factory reset before giving it away or selling it. Not ready to buy a screen as the cost is the same as buying a used device.
Well - that's everything. Hopefully someone can assist. I can post the exact steps after someone replies, but let me give a quick rundown below. If you have one you can try with a USB keyboard and see where it gets you.
Unlock device with PIN.
ALT+A
UP x2
Type SETTING
ENTER x3
UP x2
ENTER
Type TALKBACK
Enter x3
Down......can't recall. Think it was x2. To the voice option.
ENTER
DOWN
ENTER
DOWN
RIGHT
ENTER
The last bit should select the ALLOW option and ultimately enable talkback. But for some reason it doesn't. Nothing is heard. For the USB debugging it's the same thing except at step 8 it's "USB debugging" then down like 9 or 10 times to get to the option - then enter - then right and enter.
Nothing has worked so far to blindly enable either talkback or USB debugging. So any help is appreciated.
I'm hoping there's some file I can copy directly to the file system, or something I can manipulate on the file system to enable either of these features, but I won't hold my breath. No idea whether or not this will work, but hopeful all the same. Looking forward to replies and thanks in advance.
