Smashed Screen + Stuck in Adb Interface = Challenge - Nexus 6P Q&A, Help & Troubleshooting

Hey guys!
Dropped my phone. Screen is completely black. Charges fine. Fully charged now, notification light went from red to green.
Plug into PC, I hear the Windows USB mount sound, I see option to disconnect. In Device Manager, under Android Devices, Nexus 6p Adb Interface. In abd, no devices listed.
Device was rooted and 100% had debugging enabled, but since the screen went dark, a bunch of buttons were pressed and I have no idea what has happened as a result. If I had to guess.. if is in download, or recovery mode. I can't tell.
Any ideas on how I can regain access without spending money (haha, I know)? I read somewhere that the Nexus 6p doesn't have HMDI out. Is that true? So that wouldn't be an option? I just need to know if fixing the screen will fix the phone. It doesn't appear anything else is damaged, but how do I know for sure?
Thanks!

No display input from Intercept

Hi guys, I just got my Intercept, and after following this video, my screen won't display anything. It's like the screen is not plugged in but the phone is on. It still makes noises and you can still feel it vibrating, the bottom and keyboard lights still come on. This happed after the point in the vid when the download finished and the phone restarted, except my phone didn't restart. It just sat there, doing nothing. I can't get into recovery mode, or download mode. When plugged in, the PC still recognizes the phone, but it isn't mounted so I can't access any files.
Is there anything I can do? Or is it completely bricked?

Click to expand...
Click to collapse
No link to the vid. I have a good feeling what you did is used the file that came with SWUpdater instead of a file made for the intercept. Which means you have a samsung moment system on your phone. There is no known way to recover from this as it has happened to several. It isnt completely bricked no but it is a paperweight.

[Q] Nexus 4 Blank Screen

Hi All,
I have dug, and dug, and dug some more, but I can't seem to find out wtf is going on with this phone.
I was attempting to flash back to stock using these instructions (http://forum.xda-developers.com/showthread.php?t=2010312) on my windows 8 machine. However, after the last step (Step 14 in section D), my nexus simply went blank. And stayed that way. Now, I can tell the backlight is turning on, however nothing is displaying on the screen. Also, my computer is no longer recognizing it. All I can manage to get out of it is my computer is a noise after I hold down power and volume down, along with a red flash of the notification led. The backlight will stay lit, but the screen isn't even turning on. It is also not showing up as a device, adb is simply returning "waiting on device" (or similar), and it is not returning the serial number after typing "fastboot devices".
Is it possible I hard bricked it somehow? I'm at wit's end here. and I would MUCH appreciate any and all help.

[Q] (Edited) Okay, so its not in APX Mode? Would like help recovering data

Hello, first let me apologize for making another thread on a possibly bricked tablet. Also I apologize if I didn't post this in the right place, being new and all. Thank you to anyone who takes the time to look at this.
My situation:
My tablet has been working fine until last night; it's been dropped once before from a substantial height (over 5 feet), and luckily only my screen cracked, which I replaced. This time however it fell about 2-3 feet from my bed, most likely landed on the power button side, and now it won't turn on.
The Power Light comes on
It vibrates
The backlight does NOT come on. No words. No logos. Nothing.
I tried plugging it into my computer but nothing happens. It's not rooted (as far as I know), and I don't think I had debugging on. It had Android 3.2.1 on it I believe; my computer is Win 7 64.
Edit: I was able to get another computer to recognize it, a Win 7 and 8. They both have it pop up as "Acer ICONIA TAB A500" and as a portable media device, but when I open it it says its Empty... no folders, nothing.
At this point I would just like to know if there is anyway to get the personal data off of it, there are a few documents that I had not backed up yet that I would really like, that were not on my external SD card. If its possible to get it working again that would be great too, but I've come to terms with the fact it might never. (I'm half tempted to strip it to the screen again and put it back, just to see if that might make it work...)
Edit 2 (sorry if anything sounds confusing): I don't know if this is helpful or not, but the tablet "sounds" like it goes to my lock screen (powers up, vibrates, wait a minute or two and then really softly vibrates again), although I still can't see anything. The power light then goes out, but if I put my ear to the open back I can "hear" it working. If I leave it alone and plugged in, the power light will flash from orange to white every couple of minutes (it will also do this unplugged). Also if I press the power button it will turn white, acting like its sleeping and I've woken it (this occurs whether plugged in or not), but I still have a black screen. Does this mean it might not be dead?
Can the screen be broken with no visible cracks or damage inside?
Another note, when I replaced my cracked screen when it fell those 5 feet about a year ago, I never changed the green piece (which I am assuming is the touch screen controller?) with the new one that came with the new screen+digitizer. Could that be acting up now?
I'll try and see if I can get my hands on a micro HDMI to test and see if it will show up on my TV/Computer. It should just be plug and go right? No setting that needs to be turned on?
Any help is greatly appreciated, and thank you for your time.

Can I diagnose a phone with smashed screen?

A friend of mine lost his S4 I337m, but found it again after it had been run over by a car. I'm trying to determine if it's worth trying to replace the LCD or if there's other damage.
The LCD is just tiny shards of glass (I'm betting it was face down when run over) but while he didn't find the back cover, the mid frame is in good condition and after removing it, the boards don't have any obvious damage.
If I try to turn it on, it vibrates and the LED pulses blue. Then a bit later it does a longer vibraton and the LED flashes blue. It seems like it's powered up.
If I try to connect to Kies, it just says "connecting" forever and the LED turns red. Maybe it's prompting me to unlock the phone? There's no message from Kies to that effect though.
As I've never used this model of phone before, I have no idea what the normal behavior is. Are there any tools I can use via USB to check the "health" of the phone?
FYI, I'm pretty familiar with flashing Android phones (mainly Nexus devices) and have replaced the screen on a Nexus 5, so I'm not afraid of a challenge. I'm guessing this phone is stock, so probably have a locked bootloader and USB debugging disabled, so I'm not sure if I can expect much. Obviously without a screen I can't do much. Also, he pulled the SIM and SD card, not sure if that matters.
I'm going to try connecting using ODIN next.
I actually was in the same situation as you are about an hour ago. I was able to unlock my phone by using a USB OTG adapter to connect my keyboard to enter in the pin and unlock it. After that I was able to access my files, so i just kept taking screenshots while i navigated my phone using my keyboard - installed SideSync, accepted the permissions, and finally - was able to mirror my phone to my computer.
If your phone vibrates, and the LED works, then try testing the button three buttons when you have the phone on. the red LED light is only on when the phone is either powered off and charging, or the phone is powered on with the screen off and charging, so if tapping the power button changes between seeing the red LED and not (and a small vibration when tapping the back or window button) then that should mean it's just the lcd+digitizer
Anyway, feel free to ask me about any behavior about a working s4 with a broken screen, one more week until my replacement comes in the mail

Xiaomi Mi 9T all of a sudden bricked - ADB shows "unauthorized device"

Hello all,
my Xiaomi 9T bricked - no external force like a drop, I also never tinkered with flashing or something like that - I just heard a notification coming in, wanted to check on that and the phone just never turned on.
I tried getting it into Fastboot or Recovery mode, however no success. What I noticed was, that the phone was kind of recognized when i "booted" it into fastboot. I unfortuntately cant remember, if I turned on USB Debugging (think I did though) and installed ADB drivers to maybe get something done.
Unfortunately, all I get via ADB is "e42a47 unauthorized". Even after killing/starting ADB and deleting adb-files in .android folders. I don't know if my phone wants me to grant access, but since the display is black, I can't tell.
So if you have ANY ideas how to save the phone, I'll gladly try it out.
Thanks!
I decided to try again and google some more. I discovered the "XiaoMiToolV2", tried to install a new ROM. I put the phone (still showing a completely black screen) into Recovery-Mode using Power and Vol+ and selected (blindly) the "reboot" option.
Now the phone seems to work normally, it shows up in Windows Explorer (although not showing files unfortunately - I guess its not in the right mode to do date transfer) and I also can hear the appropiate sounds when charging it/disconnecting it/etc - the screen still stays black.
Any idea where the problem could be? Is this more on the hardware side now?
As already being said, it never went black after a drop or anything (drops did happen in the past though).
e: It seems that the finger-print sensor is still working too.
I am now trying the almost legendary "rubber band"-method to drain the battery and see what happens.
