Samsung Galaxy Nexus running Lineage - On/Off button fails - Samsung Galaxy Nexus

I have a Samsung I9250 which I've unlocked, rooted and loaded with Lineage. The Lineage version is 13.0-20171126-NIGHTLY-maguro. The recovery is TWRP and the root is through SuperSU FREE (CM) v2.79-SR3. The On/Off button doesn't usually work. If the phone is off then pressing On/Off has no effect. Occasionally it works for no reason I can see, it seems to be random, but for the most part it simply doesn't have any effect. If the phone is on then the same is true. Turning it off from the On/Off button is usually impossible. I get round this through Settings>Display & lights>Wake on plug. This means I can activate the phone by connecting it to a PC using its USB cable. This will activate the phone immediately if it is off. It doesn't help with turning it off and I am usually reduced to taking the battery out. The phone is effectively useless although it is clearly NOT bricked. When I can turn it on it works fine.
I don't know if this is a hardware or software problem. If it's a software problem I don't know if the fault is in Lineage or TWRP or SuperSU. I noticed that the problem existed before I installed SuperSU. Has anyone else come across this problem? I'm reluctant to bin the phone because I spent such a long time getting Lineage on to it, but, if I can't turn it on or off it's not really a phone. Any help would be greatly appreciated.

@erich_vogt it's more a hardware problem, you can buy a new button (find link of online stores in accessories section or google.it).
for easyness you don't need to plug charge/usb everytime, you can set volume button waker, find in settings > button (don't remember where correctly, it will be somewhere there) then use volume switches to wake it.

There have been power button bugs, but only in the OS. If it's not turning on from off, then I think the switch is broken! A common failure in old phones, which is why "volume button to wake" is important, to reduce load on the power button.

Thanks very much for offering to help.
I already had the option for the Volume control buttons to wake the phone turned on. It's here - Settings > Buttons > Volume Buttons > Wake up device. This worked for a while then stopped. I disassembled the phone to look at the On/Off button. I tried turning the phone on directly from the metal contact pad beneath the plastic button. This worked. When the phone had booted I checked to see if there was another nightly update for Lineage. There was the 3rd of Dec update. I downloaded and installed the nightly update using TWRP. It reported a successful install. The phone rebooted and never got past the Google boot-up screen. I waited for a few minutes and the took the battery out and tried turning on again from the metal contact pad. The phone booted but again got stuck (or seemed to) on the Google boot-up screen. I'm afraid that's it for me. This doesn't appear to be related to anything I have done or not done. The phone is just taking up too much time and it will have to go the the local recycler. Life is, as they say, too short. Thanks again for your suggestions.

3rd dec nightly has problem with booting, get back to older than it.
Reset volume button waker, if it stopped working. I never had problems with volume buttons.

I'd second the idea of it being software. I've had problems with all builds after 20171112. I get the impression there was something overlooked when the developers unified the builds for different GNex variants.
If you still have the phone, try that 20171112 build.

I don't know how to roll back to an earlier build. The phone will not boot. If I try VolumeDown+On/Off to try to get into TWRP Recovery mode nothing happens. The adb bridge option is turned on but if I connect the phone to my PC with a usb cable it does not appear in Device Manager as it used to. If I run ".\adb devices" it is not listed so clearly adb cannot find it. I don't know what else I can do.

Ah, ok. Sorry, I thought you could still do more than that, but it was rebooting and unusable in that sense.
That's well beyond any help I can offer you. I hope you got any data off it.

[Q] [Assistance Needed]GT N7100 issues

Hi Guys,
I have my N7100 for almost 3 months now and yesterday my son accidentally spilled water on it. The whole unit did not get wet, just the side where the volume rocker is. And it switched off by itself. I removed the battery and let it dry for a few hours. I switched it on and yes it did turn on but one volume button ( - ) is not working and the back and menu keys are not working also and it does not recognize any touch on the screen but when I used the S-Pen it recognized it. It's a rooted, heavy customized and tweaked phone. I noticed that it went to "safe mode", it was indicated on the lower left side of the screen and all installed apps were gone. DPi value went into default. I tried to install some apps, it went successfully but I can not find it in the apps drawer. I went into recovery mode, hoping to remove it in safe mode (foolish me, did not even tried to read or search on xda for possible fix), re-flash a custom ROM but same thing. I also found that the two water damage indicators inside the phone turned pink. The components inside were dry when I opened it, but because I am eager to fix it I tried using a hair dryer to (of course) dry it a little bit without damaging anything. After a while I put everything all together, switched it on and it now recognized "touch". But issues with volume key ( - ) and menu&back buttons still remain and it is still in safe mode. I decided to restore it to factory default via recovery mode, I cleared everything, reformatted system, data, all menus with the word "reformat' I pressed them all. Restarted the phone and it just stays on the logo where it says "Samsung Galaxy Note II GT N7100". Tried to go back to recovery mode but with no avail. I tried to go to Download mode also, I was able to make it to the part where it says "press volume up to continue; press volume down to cancel" I then pressed volume up but nothing happens. I pressed the volume up and same thing. Tried to charge it while it is switched off, the battery icon charging appeared, it shows the circle animation but it does not animate and it doesn't animate also like it's charging itself. Plugged it into my laptop and it doesn't recognize it. I've been reading some XDA articles and I only came acrossed one possible way to resurrect it...To get Download Mode without 3-button combo using homemade JIG. Well, I know for a fact that I need to send this to Samsung Service center but I am still hoping that someone here might help me or I may still find other alternative solutions without spending a lot of $$$ in sending it for a repair. Thanks in advance!
Apparently u have formatted system partition. Have u try flash via PC odin? Maybe the download mode will work with odin
Yeah, that's what I thought also. Foolish me! Apparently I can't even try Odin since my laptop does not recognize the phone. I can't even go to the download mode. It was stuck on the part where it says Volume Up: Continue, Volume Down: Cancel.
hmm.. seems like the hard key for the volume are done for. since u already disassemble it, cant u use the manual way to press? it u able to go into download mode, the driver will auto download, well at least it auto download for me
Tried that also mate, but no luck. I think the phone does not recognize the volume rocker. I just noticed that when I pressed and hold the menu key plus the power button it goes to the page where it says volume up: continue...where you are supposed to press volume down+power+menu key right? I tried to press the volume up key to continue but no luck. I was browsing xda the whole day to search for an answer before I send this so Samsung service center. I tried a homemade jig so I can go to download mode but it does not work. I have read that other SGNII users were able to make it work. On the instructions it says to use 3pcs of 100K ohm and a 1k ohm resistors but I used 6pcs of 50k ohm + 1k resistors (since I can't find any 100k ohm resistor on any electronic store near my place) connected it to pin 4 and 5 of a micro usb plug and still no luck, nothing happens. Tried some several combinations.
I have don't have good sleep since my Note II died...Haven't eat properly...Yeah, you read it right...hahaha..Still trying to search for possible fixes, it's 12:40am now and I am almost sleepy, if I still can't find any solutions until tomorrow then I will be sending this to Samsung Service center
or....if Adam will reply on this thread http://forum.xda-developers.com/showthread.php?p=39387670 then I am willing to dismantle and do whatever he wants me to do just to resurrect the phone...
Can you go into recovery mode? If yes try adb reboot recovery or reboot to bootloader if you have twrp.
this is XXXDDDAAA
Like what I explained on the first post mate, Recovery and Download modes are not possible/can't access them...

the problem is because your volume rocker key and power button are shorted due to water content.. i recommend that you take it to a service center before something worse happens... dont turn on your phone again until its cleaned properly and dried.. take it to proper service ... else its very bad for your device.. coz it can get permanently dead
Yeah, that's what I am going to do today. I surrender can't find any solutions anymore. Will keep you guys posted. Thanks anyway!
It's with Samsung Service Center now. It's OOW and they were able to find out that it was rooted (of course!) I paid Php1,200 under the table (on one of the technicians) and now it's In-Warranty again hahaha, but I have to leave the phone for a couple of days or weeks since they need to replace some hardwares. I think that's the best thing I can do instead of paying more for an OOW repair. sad sad sad..weeks without my phone with me...going back to my old phones for the meantime...

Broken Display?

ok so here is the rundown
Device: HTC one on vzw
Rom: Slimbean 2.x
Gapps: Slim AIO gapps
had a weird problem with the display today if anyone has had this or know someone who has i would greatly appreciate the help. I just flashed Slimbean 2.x last night and all was good. no problems what so ever, got everything setup and was working fine. this morning around 10am i opened snapchat to view a video. i clicked on the video and as soon as it started the screen went blank and would not turn on. i tried holding the power button down for at least a minute and nothing. also tried power and volume down, power and both volume buttons, power and volume up and still nothing seems to work. when i plug it into the wall charger the red LED light does not turn on and screen does not wake. when i plug it into the computer the computer does not ever read the device and noting pops up letting me browse the files on the phone. i have no clue why this happened it has been working fine for the 3 months that i've had it. took it to verizon about an hour ago and they didn't know either but they are sending me a replacement htc one. all i really want now are my photos that i have on the phone.
does anyone have any ideas about what i could do?
thanks
I had something similar and think it was conflict related. After installing the "advanced power menu" with xposed, I had an issue when trying to use it to boot into recovery. Basically it had timed out and then went away without rebooting. The next time I tried it locked up and my screen went black. My keys would light up if I clicked on the power button (it was dark in the room so the sensor was still working), but nothing else. Nothing I did would make the screen turn on at all and holding down the power key to reboot did not work. I just planned on letting the battery die out. After about 45 minutes, the phone just rebooted and everything was back to normal. I really think it locked up due to a conflict similar to what a PC might do.

[Q] Universal Switch enabled, screen unresponsive

So I activated Universal Switch on S6 Edge to check it out, something went wrong in the settings (long story short, got a pop up while setting it up), now screen unresponsive.
It works, I just get this blue horizontal line scanning the screen and nothing else but the power button and home button works. Tried safe mode, no bueno. How can I disable US feature without resetting to factory or at least no data wipe (if possible!)?
Android 5.0, rooted with pingpong, no custom recovery, knox 0x0.
All help is appreciated.
Same
[The exact same thing just happened to me someone please help
Fixed!
The way I had fixed this is by holding down the power button, both up and down sound buttons, and the home button until it restarted. When the device turned back on it gave the option to turn the setting off. Hope it helped!

how to turn off universal switch
hit home button 3 times
Thanks alot
It worked buddy
It doesn't give me the option to turn it off
Hi,
I have been struggling with Universal Switch on a Samsung S5 Neo. I switched it on, but was never able to switch it off again.
These are findings so far:
-> Did a factory reset using "Sound Up", "Home" and "Power" button simultaneous.
-> The device comes back and wants to configure itself again.
-> I restored my settings from Google, but this immediately brought back "Universal Switch"
-> Factory Reset again and configured the device, but told Google that I want to use it as a "New Device".
-> Now I can use my device in a proper way.
-> In Google Play Store I find all my Apps which were linked to my account and reinstalled them and I am back in business again.
-> Took me half a day to sort this out.
The programmer who designed and programmed this should be hung and shot and poisoned, because this is absolute Crapware.
Hope this helps for all the others who are suffering.
You can also push the home button three times and it should turn it off.
thank u ur the best
Ok, so i have exactly the same problem except my home button doesn't work
Anyone one know how to sort this without having to take it in to a store?
I was faced with this problem before and looked everywhere and couldnt find a fix. This was a while ago. So I dont remember what I did to clear it. I was cleaning off the screen and touched the home button as I was wiping it off and the problem began again.... I just came across your comment because all the others failed. I pressed the home button 3 times quickly and the blue lines stopped scrolling. In addition, I went over the accessibility and I turned off the "Universal Switch" option as much as the option allows. I hate this function. I do not use it or need it (for my needs). I hope I can remember what to do next time this happens. I swore to myself I would remember last time, but apparently that wasnt a guarantee. This time, I will write it down and put is somewhere I know I will find it next time I see these nefarious blue lines scrolling. Hopefully I wont see it again since I disabled it more than it was to begin with. Thank you ever so for commenting. You saved me a lot of frustration!
great fix

I have also tried rebooting it with the option suggested by you.. but I am locked due to password protected... My device not asked to disable Universal Switch option after reboot as well..
Please help, how to get this Function Disable, without affecting my data as I do not wish to loss any of my data..
So what the heck is that scanning blue line option supposed to do?

same issue
it works with OTG cable + mouse

Screen froze, asked for reboot, now nothing

My wife was typing and the screen froze, she pushed the power button was the reboot or power off box appeared. She selected reboot and the screen went dark and now nothing comes on no matter how long the power button or power + power up or power down is held. I plugged in the charger and the battery icon does not appear. Could the connection from the motherboard to the screen have come loose? It seems strange that it would die coincidentally after requesting a reboot. Another other suggestions before I try to sell it as a paperweight on Ebay?

It depend on if you had TWRP Recovery installed on your tablet. Was this an original setup device or a custom ROM? If it was custom, you should have the necessary files to reinstall from scratch. If you know you do have TWRP Recovery installed (IIRC, it would not show up as an installed app) then to access it you need to push POWER, HOME button (middle front panel)and VOLUME +(up)at the same time! This will get you into recovery mode. Then, you would have to reinstall your custom ROM and gapps from backups. If you don't have these you may still be able to repair it via a Windows PC connection with the right files.
When you post probs you are having, the more info that you include, the better chance you will get a solution for it. I have three smp600 tabs, all configured the same way with multiple backups for each on SD cards as well as Google Drive cloud. So, I can have any tab restored fully in under an hour. Whatever you do, good luck, but it takes a lot to truly "brick" one! ;-DeanoD=

Thanks. It was running stock Lollipop with no custom recovery. When I was taking the back off to see if a connection was loose I could hear audio but I did not find a loose connection so it's still dead.?

Black Screen, but not quite a brick. Please help!

I'm posting here because this is the only place I can think of to turn to where people are both knowledgeable and helpful.
I have a Pixel 3 XL, which I've had since November, and has worked without incident until yesterday. One of my main reasons for choosing this phone was the alleged support for root, but I haven't actually rooted it because the guides that I've seen up to this point still seem to indicate that there is some loss of functionality involved.
Yesterday I went for a walk to visit an old neighbor. The phone was at about 80% charge when I left, and working fine. At some point during the visit, I pulled out my phone to check for any messages, and couldn't see the screen. I thought it might be because it was bright outside, so I put it away again. A little later, I checked it again and still couldn't see, so I went indoors to look. Nothing. The screen was completely blank, and the phone wouldn't wake up from the fingerprint sensor or the power button. I tried holding the power button down for 10 seconds, then 30 seconds, then a minute and more, and nothing. I figured maybe the power had drained and it was off, so I'd check it out later. A little after that the phone rang, but the screen was still off and I couldn't answer it.
To fast-forward a bit, at present the phone is *almost* functionally a brick. If I get a call, it rings and vibrates, and if I swipe from the right spot on the screen I can answer the call. Also, alarms that I had set on the phone still rang this morning. Unfortunately, that's it. Without any indicator lights it's hard to know for sure if the phone is on or off, and no amount of holding down the buttons seems to do much more than maybe reboot it. I cannot reach the phone using Airdroid, Teamviewer, or Find my phone, so there seems to be little or no network communication happening.
I called Google, and their suggestion (after trying to get the phone to ring with the Find my phone option) was to try to erase everything. While I don't think that will work, I also don't want to try. I don't want to wipe out the phone without saving everything on it! They gave me the standard line about "most of your things should be backed up," but that's not true of apps that weren't installed through the play store, along with all of the associated data for those apps. They told me to take it to one of their partner companies, "ubreakifix," to have someone look at it, but the person at the store said they wouldn't be able to look at it for a few days, and that wiping out the phone is the first thing they'd do anyway. They say I just need to send it back to Google, and that they'll either fix it or, more likely, send me a replacement, but that they'll wipe it out too.
I find this incredibly frustrating. Without removable storage, everything is locked up inside the phone when something like this happens. Without root, I don't have the access authority to fully backup apps and data. Without a removable battery, I can't even fully power down and restart the device! On top of all of that, even if I get a replacement, there's no guarantee that this won't happen again, since I have no idea what caused it this time. I didn't drop the phone. I didn't spill anything on it. I just put it in my pocket like I do every day.
So here are my questions to you, the members of the developer and modding community: Is there anything else I can do? Does anyone know if I can pry the thing open and attach a cord somewhere internally to access the on-board memory? Is there a way to determine for sure if the issue is the screen, the motherboard, or something else, short of sending it out to never see again? Am I the only one who finds the attitude of wiping out a phone as the default practice for any difficulty to be incredibly frustrating? I would be grateful for any suggestions or insights that you may have to share!
Thank you for reading this, and I hope to get some good news.
Not sure if it's similar to your situation or not, but a few weeks ago I rebooted my phone because it wasn't syncing with my Fitbit. I rebooted it and walked to the kitchen. Came back and hit power button, nothing happened. Fingerprint sensor, nothing happened. If I pressed and held the power button I could feel a brief vibration like it does when the power menu slides out, but the screen was off. I didn't get any calls or anything so I can't say if I could have answered them like you did.
I pressed and held the power button for 5-10 seconds trying to induce a reboot and nothing happened. I tried power and volume down to get to bootloader and nothing happened. I held power again for about 30 seconds and it rebooted, but it erased all my wifi networks. Other than that, everything was normal. I was on the Q beta so it could be related to that.
If you happen to have USB debugging turned on and your PC is authorized you can try using these commands to force the backup to run and backup your SMS, calls, apps/data (for the ones that are supported). I know it's not much but worth a shot.
Code:
adb shell
bmgr run
bmgr backupnow --all
I usually run that before opting into/out of a beta, flashing/factory resetting, etc.
Hope this helps!
Thanks for the quick reply.
It sounds like your experience wasn't entirely like mine, but it does bear similarities. I'm curious about it erasing your wifi networks...might that be a factor in why mine isn't getting online? It wouldn't explain everything, but suppose wifi and/or wireless data is turned off (for some reason), and the phone could theoretically still be functional without seeming like it.
I have a micro USB cord with a little adapter to USB-C that I use for charging. I tried plugging the whole thing into my computer (I've got a chromebook with me right now), but it didn't notice anything being there. I don't know if this cord works only for charging, or if it works for data too, and similarly without the screen turning on, I don't know if the phone is set to allow connections, although it should be. I'll try to get a different cable this evening and see if I can get further. If adb works, I'll definitely try those commands.
Thank you again, and any other thoughts are still very welcome!

Cords are kind of goofy. If you have a machine that supports C-C or an A-C cable, I would use that. In my experience they work much better without adapters. Also with a Chromebook, about the only thing you'd likely see is the photos folder if it was in PTP mode (I think). The Chromebook may also have a notification about it providing power to the USB device, but I'm not 100% sure. I don't think the microUSB->C adapters can do data, or at least the C->microUSB adapter I have (my Bose headphones are the only thing I keep in my bag that charges with microUSB anymore) does not do data.
Does the phone do anything when you press the power button? Does it vibrate at all, or if you keep holding it does anything come on the screen (Google logo, recovery, fastboot, etc). I'd try getting into Fastboot and see if the screen itself works. If it does, that might be a good sign. Hopefully you can then get into recovery and do a reset. I would suck to lose all your apps and data and stuff but it would be better than the brick it is now, I guess. You can go here and double click the device to see what is backed up and when it was last backed up: https://drive.google.com/drive/u/0/backups. I know that won't help you with non-Play apps like you said in your OP but it is better than starting over 100% from scratch.
If you can approximate the location of the buttons you could also try swiping down to the notification shade and tapping the quick tiles you might have in your top row. For example I have Flashlight as my far right one. If you can guess roughly where it might be you can see if the flashlight comes on, which might help determine that the screen is the issue, etc. Double tap power button to see if the camera opens (vibrates when it does) etc.
If I think of anything else to try I'll let you know.

Agreed. I was a little annoyed at the tech I went to for telling me that "the charging cable is a data cable, they're the same thing."
As a brief update, I got ADB installed and running on the chromebook in anticipation of trying the commands. Plugging in the phone yields nothing in adb. However, I also tried with someone else's phone (after enabling developer mode and USB debugging) to see if it's the computer, and it doesn't see that phone either, so maybe I'm missing something else in how it works.

Pressing the power button doesn't do anything noticeable. No vibration, and nothing on the screen. If I touch the fingerprint sensor I get the little vibration of acknowledgment that usually means that the phone is unlocking. A further complication comes from the fact that the first time after rebooting, the phone requires a code and won't unlock just from the fingerprint. I found that when I pick up an incoming call (by touching the right part of the screen), the number buttons (for dialing) respond as well. I don't think they're in exactly the same place on the lock screen though.

Yes, that would help if I could figure out where those are on the screen. I don't remember for sure what order things show up in, though, and I don't know if that menu even comes up if the phone isn't unlocked. Double-clicking the power button doesn't do anything either, whereas it usually vibrates a little and launches the camera.
I still plan on trying to get a different cable later, but if I can't get something from ADB on a different phone either, I might need to wait until I can use a different computer.
Another update:
I went and bought a new USB-C cord and hooked up the phone. ADB does, indeed, recognize that there is something there, however it gives me this:
error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
A little searching turns up suggestions to delete one or two files (which I did), and....disable/reenable and accept the incoming connection on the phone! Well, I can't exactly do that. Any ideas on what to do from this side?
Thanks again!

Guess what? I found the flashlight. I called the phone, answered by swiping the general location, and tapped around the screen listening to touch-tones until I had a decent sense of where the number pad is on the screen. After hanging up, I touched the fingerprint reader, tapped my password into what might be the location of the numbers, and then dragged down from the top of the screen to get to those tiles. Tapped a little here and a little there, and lo and behold, the flashlight toggles on and off!
So at this point, I'm not *sure* that I've logged into the phone, although it seems plausible, and confirmed that behind the darkness there is something running. If you're right about the wifi having been forgotten though, it may be hard to check on whether it's connected. I don't suppose you could share a screenshot of giving ADB permissions so that I have an idea of where on the screen to tap if the message is popping up. If I could get that to accept and then get into the phone with ADB to back up my files I would be far more at ease with sending the phone off for repair!
Current status: slightly less of a brick than before, but still a ways to go!
Unfortunately the flashlight will toggle on even when locked. Also, depending on your lockscreen notification setting you would not be able to grant your computer adb access without the screen unlocked. Try holding the button combo to get to bootloader with the phone plugged in. That way you can hear a sound through the chromebook if it disconnects and reconnects. If you get that use fastboot devices to see if it is recognized. From there you could try to flash factory image without wipe and see if it helps.

Hm. I hadn't realized that the flashlight works from the lock screen. Any idea what else works from there? Is it possible to toggle wireless data, wifi, airplane mode, etc from the lock screen? I've been tapping around the area where the flashlight control is, but I don't know what, if anything, is being accomplished.
By a combination of button presses and the fastboot reboot-bootloader command, I'm reasonably certain that I'm getting it to boot to the bootloader (at least it tells me on the chromebook that it was successful in that), but there's still nothing on the phone's screen and I'm not sure what to do from there. How do I flash an image without wipe, and what would that accomplish? Ideally at this point I'd just like a way to either perform a backup or outright copy files from the phone to the computer, and I need a way to grant the permissions to allow that.
Thank you for helping!

@FireflyII
To install the factory image without wiping data or internal storage edit the flash-all file. remove the minus w (-w) before update.
- Then connect your phone to the computer
- Open a Command prompt in the Platform-tools folder.
- At the command prompt type flash-all
If it is successful your phone should boot into the OS
Do you have a USB keyboard handy? I just connected mine via the USB adapter in the box for my phone, rebooted and used it to put in my PIN and get into my phone. After rebooting I tapped the fingerprint sensor to show the PIN screen and typed my PIN on the numpad (had to turn numlock on) and pressed enter and it went to my home screen.
I swiped my notification shade down (two long swipes to get it to show the settings icon) and was able to use TAB to get to the settings gear (19 taps of tab...) and press enter to get to settings. From there you could try getting to the USB Debugging settings. Here are some screenshots to help with that:
Scroll to the very bottom of settings and pick System if you've already enabled Developer Options:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If you haven't enabled it before you have to go to About and scroll to the very bottom and tap Developer Options 7 (I think?) times. I can't remember if it requires a PIN to enable or not.... someone else might need to sound off on that one.
On the System screen about halfway down there is an Advanced rollup. Expanding that shows Developer Options:
Once you are on Developer Options what I did was touch just above my home button on Apply Automatic Updates. I slid my finger up so that it was even with the VOL UP button, that brought "Enable USB Debugging" to the area just above the home button. Toggle is on the right:
Also to build on what the others have said, if your bootloader is unlocked you could try flashing the factory image (remove -w from the flash-all.bat or sh to preserve data) to see if that gets it going. Hopefully the keyboard helps making things a little easier to move around.
--After I typed all that I realized there is a search bar in settings. Mine doesn't seem to be doing anything, might be a bug in Q. I connected the keyboard to my fiancee's Pixel 3 (not XL) and typing "USB Debug" didn't find anything but she has Developer Options off. Looks like you can search for whatever screen you're trying to get to and it should even scroll to that option if it's not on the screen. Once on a screen you can use the arrow keys to move through them and press enter to go into that screen. Might be a little easier to use a keyboard for navigation than going blind
Hope this helps!!!
If you never rooted or installed twrp you should have factory recovery and could try an ota (would be blind hard button pushing). If bootloader unlocked you could try factory image without wipe. It would be a last attempt I guess. I think adb is available in stock recovery to do backup maybe (Again blind hard button pushing). If you have unlocked bootloader you could try to do a data backup with twrp, though that would be blind screen button pushing, which is not easy.
Somethings we need to know, did you unlock bootloader? What is the state of developer options?
I am only saying a factory image flash to see if your screen comes back. If it does not it must be some issue with the screen, not a software issue. Was the the phone ever dropped? Any reason a connection might have came loose?

I'm traveling today and will have to try this out tonight. Just to clarify a few things though, where are these files? I've flashed other phones with custom recovery and ROMs before, but not this one yet. Will it be obvious when I download the factory image?
Also, assuming that the process works, where does that put me? I understand how it would help if there is something corrupt that is keeping the phone from working correctly, but in that case I would expect the screen to show something, at least when rebooting. If the display is physically broken and the phone is otherwise working, does installing the factory image and letting it start up mean that it will let me connect with adb? I would expect the result to be either the same as where I am now, or possibly slightly worse if it resets to non-debug-over-usb mode! As I said, I'm up for trying it, but I'd like to know what changes to expect beforehand, if possible.
Thanks again.

It sure sounds like something happened to the screen to me. Could be a connector unplugged, bad display, etc. Flashing the factory image isn't going to help any of that.

Absolutely! I didn't know that you could use a keyboard to enter the PIN, that is certainly helpful! Thank you also for the screenshots and descriptive locations for things. I've got about another hour or so before I get home and can try these out, but thank you very much!
Happy to help, man. Let me know how it goes or if you need any more help. ?

Well, I have something of a new development now. After traveling all day and not knowing for sure if the phone was on or off, I wasn't getting much from it on Tuesday night or Wednesday morning, so I plugged it in, waited until I got the flashlight on, and left it to charge during the day while I attended to other things. This morning the alarm on the phone went off, and I swiped to the side...a bit later it rang again, so I assumed I had done "snooze" and swiped the other way. Again, it rang after a while, but this time I let it go. Once I had a moment, I pulled out the charger and tried the keyboard. Nothing. Now the phone is totally inert--it doesn't ring when called, the flashlight doesn't respond, and no amount of pressing and holding the buttons brings it back. However, almost as soon as I plug it in again, I am able to use the flashlight. Disconnect, nothing. This seems like a power issue to me. Ordinarily at this point I'd open up the phone to check out the battery (okay, honestly I'd have done that a while ago), but the phone is sealed. I found a tear-down guide on ifixit that suggests using suction cups and possibly a heat source to pry the thing open, but I don't have any suction cups on hand and am dubious about finding ones strong enough locally.
So to sum up:
The phone is a brick until I plug it in. At that point the little fingerprint sensor vibrates when touched, and I can toggle the flashlight on and off. I can disconnect the power and still have the flashlight working until I touch the fingerprint sensor again. At that point, it doesn't vibrate, but the phone returns to brick status.
*sigh*
Time to call Google again, I think.

Does it provide any power to the keyboard? If you turn the numlock or capslock on you might be able to see if the keyboard is powered.
I just plugged one in and tried it and found tapping spacebar brings up the PIN entry. Get it to boot, tap spacebar enter PIN and hit enter. Like I said, that might not do much if you can't confirm you're in without a screen...
---------- Post added at 02:39 PM ---------- Previous post was at 02:37 PM ----------
Also, have you tried using a wireless charger to see if that does anything differently? Might be useful to charge wirelessly and use the USB port for keyboard if it dies without a charger?
