Hi,
I've had my N7 running Multi ROM with rooted android and ubuntu touch. Today i knocked it off the side while it was charging. Now all I can get is either what I assume is back light only. Or sometimes it comes on with a black back ground and white lines jumping all over the screen.
I'd like to get it back to stock with the bootloader locked so I can try to get this fixed either under warranty or insurance.
The problem I've got is that I can't get the device to appear under "adb devices" or "fastboot devices". When I got Multi ROM running I did it through Ubuntu using adb\fastboot commands rather than any took kits.
Any suggestions of how I can get the device to show up in adb or fastboot would be much appreciated!!

I decided to rip the back off again to pull the battery for a bit and see if that helped. At which point I realised that the battery wasn't correctly connected. Even though I thought I'd already checked this. My N7 is fine.
Hello all,
I have an LG NExus 4 which has a cracked screen. The top half of the screen detects touch input but the bottom half does not. Which means I cannot press "Enter" after keying in my passcode for the lockscreen. I have some data I would like to backup. I ran the adb devices command. It returns a serial number but also it says unauthorized. Do you think you could help me backup data?
Appreciate any help you can provide.
So I have a Nexus 4 with 4.2.2. I dropped it yesterday morning in the dirt this morning, it fell out of my bag maybe 2 feet off the ground.
There is a small scuff on the left upper corner and the lower half of the touchscreen no longer works. Only buttons on the top half of the screen respond. The display is completely intact though, not shattered and displays images just fine. Since the lower half screen is unresponsive, I can't enter my SIM PIN or unlock my phone.
My skill level in this area is pretty low. Enabling LTE is pretty much the most technical thing I've done with this phone.
I do have twrp but it appears I do not have USB debugging enabled. I've been googling this mess and experimenting with adb and fastboot for the last hour but haven't been able to make any progress backing up my phone or enabling USB debugging. I was thinking if I could at least enable USB debugging at least I could use Control Android or something right?
I'm able to connect using adb but I must be using incorrect syntax. I've tried every command I have come across and always get a not found error. Is there some other referance I should be using - I started with developer.android.com/tools/help/adb
~ # ←[6nadb devices
adb devices
/sbin/sh: adb: not found
~ # ←[6n
C: \adt\ sdk\ platform-tools>fastboot devices
0047e1b856555005 fastboot
I will be getting a new phone but my primary concern is there are a handful of text messages from my boss sent me literally minutes before I dropped my phone and he is now unreachable for the next week.
Is there any possibility the digitiser came loose and that's why only half of the screen doesn't work? I need to buy a #5 torx driver anyways but I don't want to open it up if its not a viable solution.
Any other suggestions?
Just boot into TWRP and type 'adb pull /sdcard/' in a console. Recovering text messages I'm not sure how to do, might be doable through a shell.

So Im waiting on a replacement screen (it started as crazy graphics all over screen, not completely blank, but responds to input), and its taking forever. I knew I had ADB debug enabled, so wondered if I can control the phone via PC.
Behold there are few ways this can be done.
Long story short......in adb, my phones shows as ADB DEVICES : UNAUTHROIZED
Is there anyway I can authorize the adb request between computer/phone?
Its a stock OnePlus 5.....so no custom recovery and not rooted :-/
You could guestimate the area or the enter button of the dialog, and use a mouse connected via USB otg to click it

Best way would be to use a displaylink adapter do you can see the screen.
If you can make it through the menus you'd need to install the app which can be done from a PC, just push it to the device, then advanced, then turn on usb, then allow the app. Then the screen will be shown on a monitor.
Either that or change the screen.
I got it working......I had to boot up an old laptop hard drive I had that was Auth'd. It let me do what I needed.
Hehy there,
unfortunately the screen on my mi9t stopped displaying. Really weird. While I was using it, the screen started flashing, just to turn black and never wake up again. No fall or water involved. The phone still seems to work fine, and even touch seems to work, but no display.
I opened up the phone to see if the connector got loose, but everything is well in place.
Now my problem ist, that I can not access the phone anymore. All my files and things are still on there but unreachable.
Here are the facts:
- no display
- bootloader is locked
- usb debugging is enabled, but my pc is not authorized
- I can blindly get into fastboot and to the lockscreen
- I am not able to blindly unlock the device
Easiest option would obvoulsy be to exchange the display, but unfortunately I can not get on here (South Africa) and shipping would take a month.
My favourite aproach so far was to mirror the screen via Vizor, but unfortunately it needs to install the according app on the device, which it can not while the device is locked.
Does someone here know how to recover the data?
Thanks
and a happy new year to everyone!

When I experimented, I was able to unlock my two SIM cards and Android by adb (replace xxxx by your PINs)
However, phone was rooted and shell was given the root grant:
adb wait-for-device devices
adb shell
su
input text xxxx
input keyevent 66
input text xxxx
input keyevent 66
input touchscreen swipe 930 880 930 380
input text xxxx
exit
exit
try fastboot apk
Mirror screen to pc with vyzor. You have usb debugging turned on, so it's worth a try.
If touch doesn't work, use usb otg adapter to plug keyboard or mouse
There's no other option.

Thank your for the idea! Unfortunately it does not work in the unrooted phone. I suspect that's only because I can't the adb connection to my pv authorized.
I tried this on an unrooted lineage os 17, which I have on my old Mix2, and there it works like a charm.

Thanks for the advice. I think i tried everything to get the apk installed, but I can not do anything through adb since even though debugging is activated, the connection to my pc is not authorized.
I guess I have to wait for the replacement screen.

Any water exposure? Ever?
May not be the screen; a mobo failure is just as likely even more so especially if they use no lead solder paste.
Maybe a loose or bad connector/cable if you get real lucky... and find it.
