[Q] Starting ADB without having a screen? - General Questions and Answers

So here is my problem everyone. I have a Tablet that I would like to get a replacement screen for, but as of right now don't have the money to do so.
But, I would still like to use it, using a remote control app, from my PC. To get it setup, see the specs, etc.
BUT where the screen is broken, and I've never logged into it, I cannot install any apps just straight off the web.
So my question/thoughts are, I need to start ADB without being able to see at all on the screen some how. Then from there I can figure out myself how to push .apk files over using that, install a remote control app, and the root it, and get it all nice and setup
BUT I don't know if it's possible to start ADB without being able to see, although the touch sensor is still working even though the screen is cracked.
Any help?

Black Screen - control NON ROOTED android through PC

I am using an HTC Vivid on AT&T that is NOT ROOTED, I fell on my phone and now my screen comes up black (think I broke the LCD). I can still receive calls and I believe messages as my green message light blinks. I need to know if there is a product that will let me view/control the android phone screen on my PC without having to install anything on the phone itself as I can't see anything on the screen so I can backup my SMS messages, apps, etc... before moving to my new phone. Most of the threads I have read point to solutions for ROOTED phones which don't help me.
thanks!
Probably (but probably not worth the trouble)

So if you connect the phone by usb, it's probably asking you if you want to allow it to be mounted on the PC, but you have no way to answer, right? Similarly, no way to get it into adb mode. So those are out.
Even with the screen dead, you should be able to get the phone into fastboot mode (check the forums for the Vivid to find out how, probably involves holding the volume buttons for a while while you reboot). If you then install fastboot on your pc, you should be able to download the whole content of the ROM. Then with some reasonable effort, you should be able to untangle everything and read your messages. It can probably be done under windows, but would be a hell of a lot easier under linux, and it will require linux/android skills/understanding (even under windows). Even with those skills, it's probably going to take a day or so. Without them, far longer (or you could hire a CS student with the right skills for a day, I guess). And on the other hand, if your phone was synched, you're probably going to get a fair bit of it back when you connect the new phone. So is it worth the effort?
Our new app, VMLite VNC Server, should help you to deal with this special situation.
It works on non-rooted devices, basically what you can do is to install the apk from USB connection, and run our desktop program, VMLite Android App Controller to start and stop the app.
This way, you should be able to control and view your phone from a pc.

Issues with Android Control

I'm trying to get AndroidControl working, because my screen and digitalizer is broken on my XT907. The issue I'm running into, is that AndroidControl never recognizes the device.
Running through the cmd, adb devices doesn't list it, so it's not picking it up. I understand that adb must be enabled on the phone, but can't find a way to do this, since the screen is broken. Every fix or workaround involves some other program or action that requires seeing the screen or having touchscreen capabilities, which I obviously don't have.
Is there anything I can do to get this taken care of ? Neither my roommate nor I can find anything that works. Please help!

can i root and install vnc server completely without display/touchscreen

Hi all.
Basically, my display and touchscreen aren't working. For why, you can see here: http://forum.xda-developers.com/goo...eakerphone-t3043151/post67360800#post67360800
So I managed to get access to files (pictures mainly) on my phone by, without access to the screen/touch, installing TWRP and entering into recovery mode and using ADB (pull). Installing TWRP was all from computer, and I didn't have much interactivity with the phone itself during this process. Luckily my phone already had unlocked bootloader (which I believe during that process you have to confirm something on the phone itself?).
So now, I want to go a bit further and get more access to my phone. Best way to do that, for me, seems to use VNC server on the phone. Unfortunately I don't already have one installed. And it looks like most of them need root access?
So (as the subject implies), I'm wondering if its possible to root my phone from my PC without needing to do anything on my phone -- well, if I need to push volume up/down and power button to select stuff, that could work, just can't press anything on screen of course.
Assuming that is possible, I'd have to find a nice VNC server apk and install it via ADB install, correct (sorry I'm not very experienced in all this).
Assuming that works, I'd need to ensure that the VNC server starts on boot.
Assuming that works, if I remember correctly from when I was rooted before, when the VNC server (or any root-needing app) starts, SuperSU pops up and asks if I want to grant that app access. So somehow I'd have to have SuperSU (or whatever alternative) automatically grant it...
So, anyone think this is possible? If so, any hints?
I'm also open to any other way to gain more access to my phone (ie, not using VNC etc), if anyone has any feasible suggestions.
Thanks

What exactly do you want to access on your phone?
Hah. Good question. I don't really know. Wanna poke around and see if I'm missing anything.
I know I missed a bunch of WhatsApp messages that came in while phone was on and I couldn't see anything. Of course that's not super important.
Basically would like to poke around to see if I missed grabbing anything.
Now that I say it out loud (or type it on the forum), I begin to think it's not worth the hassle.
Maybe the real reason is the challenge, and seeing if it can be done?
Like I said. Good question!

Use PC screen as a screen for my S7? Screen shattered, but phone works

i was wondering if there's a way to connect my S7 (Tmobile version) to my PC and do some backups from within some apps and get data out of it by using the PC monitor and mouse to navigate the phone screen? i know i can go into file system and whatnot, but is it possible to replicate the phone screen on the PC? thanks a lot for any help
I don't really understad the question... What do you need, to mirror the phone screen on the PC and use its periferics or make a backup of your phone apps?

i have a shattered screen on the S7. the phone itself works - it turns on, it gets audible notifications, etc.. the only thing not working is the screen. i took it to 2 shops and they tried putting new screen on the phone but could not get the new screen to work. so i think there's some sort of short in the electronics from motherboard to screen. ideally, i would like to somehow get the screen working so i can do a backup to cloud of all my contacts, messages, media, whatsapp conversations, etc. but if i can't get the screen working then perhaps i could somehow connect to PC and get what i can from the files. i don't know how to get it to connect to PC at this point because the phone doesn't get recognized on the PC when i connect.

does this require the app to be installed on the device somehow, because i wouldn't be able to do it without a screen present.

I think running the program on your pc will install the app automatically via ADB. No need to interact with the phone

How do I enable adb debugging and otg with a black screen and no otg cable?

Hello, I just broke the screen of my OnePlus8t Verizon network unlocked phone. The computer I previously linked 8t with also has a broken screen. ... Rains it ..... My Phoe has some important information in docs and screenshots I need to get. I just turned off ADB debugging thinking "Oh I don't need that just yet" the very morning I broke the LCD. Good news, I can still answer it. I already have adb.exe except in ADB shell it shows as unauthorized. I need those files like yesterday. I have an otg/ADB flash drive, but I still can not connect to retrieve files. I can see my phone when I directly connect to comp without the flash drive, however, I can not access it. I have tried to put the phone into recovery, but I have no way to enter the pin as I have tried to guess where it is. How can I receive the data I need from my phone?
Thank You.
P.S. I have little knowledge and only learn what I need to know for whatever project, in other words, I can not code and I barely speak dos.
Is the touch screen still working then?
If it's showing "unauthorized" you can try to plug it into your desktop and then hit the "authorize" button on the popup that you can't see.
Here is where ok is on a different phone. It's somewhere near there on yours.

I have tried that. The finger print unlock screen only works ⅔ of the time. I have no way of knowing if it's unlocked. I keep my touch sounds silent. I keep trying to find where it might be. I have tried to slide as if answering a call. Is there a way to force the USB settings for media transfer? Maybe through Google? If any platform knows it's my phone is Google. I can go to the play store and push apps onto it. Unfortunately the two adb drivers I have installed on my Android didnt work.
Oh, actually, you've got it easier! The OnePlus 8t supports HDMI over USB Type C.
https://forum.xda-developers.com/t/does-one-plus-8t-have-video-out-through-usb-c.4465629/
Buy an adapter and hook up an HDMI monitor/TV.
Or just use a new monitor on the computer that is already authorized.
Is there any other way. Right now it is not with in the budget to afford any extras even with the price tag of $20. I am hoping there is a way within an adb shell to force turn on the adb debugging. I have developer options enabled. I would just rewrite the documents, except some of those items I need include the text messaging history. If I can't force the adb, can I remotely back up the phone? Is there a trustworthy app for that? I do have quick settings installed and if my memory is correct, I believe I have sideline installed even.
