I've been reading various threads and tech posts for hours and feel like I'm going in circles and getting absolutely nowhere, so I'm really hopeful someone can help me out.
I broke the screen and digitizer on my AT&T SGH-I337 Galaxy S4 with stock Android 4.2.2 and ROM, though it is rooted. I was trying to control it via the computer with 'Ultimate Touchscreen Control for Android' or Screencast, but they require ADB which I'm pretty sure is not enabled. I did enable USB debugging before the screen broke, though I can't say with 100% certainty that I didn't later disable it, so I'm not entirely sure what the status of that is. I've been reading about sideloading a kernel with ADB enabled through recovery, or using CWM with Odin to enable it, but I have been absolutely unable to figure out how to do it with a broken screen. It doesn't help that it's been 3.5 years since I really messed with stuff like CWM and custom ROMs, and I've never used Odin, and my knowledge on this stuff is not great. Any help would be greatly appreciated.
I think you're pretty much sol. You say you're on 4.2.2, do you know what bootloader you're on. Mdb, mdl or mf3. If you're on mf3 you won't be able to flash a kennel. Do you have a custom recovery, and if so, which one?
When booted into recovery and adb installed on your pc in a Windows command window type
adb devices
If you're devices serial number shows up you have adb debugging enabled. If it just shows waiting for device, you don't.
Your best bet is to get the screen/digitizer replaced.

Not sure what bootloader, but I got the device only a month or two after the S4 came out and immediately rooted it with Motochopper and it hasn't had any updates since, so it has to be an earlier one, probably the first.
After several attempts, 'adb devices' gave me:
"List of devices attached
da916528 unauthorized"
The first several times it would just say "List of devices attached" with nothing following.
'adb shell' resulted in "error: device unauthorized. Please check the confirmation dialog on your device."
Shortly after it does list the phone, the phone shows up in Windows, so I'm thinking it's not going into recovery. My timing must be off because I can't see the screen to know when to release the buttons.

You're close but unfortunately no cigar. You have usb debugging enabled but it's waiting for you to authorize the device by clicking accept on the touch screen. Which you obviously can't do. If you used motochopper you are on mdb or mdl bootloader which means you could flash a kernel but you'd have to do it in a custom recovery and use the touch screen. I don't have an i337 so I'm not going to be much more help. Sorry.

Kinda figured it was something like that. Thanks anyways, at least I know exactly where I stand now. I'm going to try using an MHL and OTG adapter to see if I can click it that way. In the meantime, hopefully somebody with the same phone as me will come along and be able to provide further guidance.
So I was finally able to gain remote access with some crazy wiring and a lot of patience. I'm putting this here so others in my situation might have an easier time at doing it.
First I installed TeamViewer QuickSupport (TVQS) via the Play Store online, then connected a PS/2 mouse to the phone through a OTC cable and a USB to PS/2 adapter (only USB mouse I have is wireless, but good to know you can use such an adapter for this). I blindly swiped the screen to unlock the phone, then connected it to my TV with an MHL adapter and the 5 to 11 pin Samsung-specific adapter. I long-pressed the menu button to activate voice search and said "launch TeamViewer QuickSupport," then when the app opened it showed me the ID to connect to the phone which I entered into my desktop TeamViewer application. I then had to switch back to the mouse to do some more blind clicking to authorize the connection, then again to authorize the remote control, which took several frustrating minutes of switching back and forth between the mouse and the TV. One mistake I made was not installing the remote addon at first, so after I first authorized the connection, I didn't have that option, so I had to install it again through the Play Store online then close and relaunch TeamViewer on the phone and reauthorize the connection before I could start a remote session. Once I was FINALLY in I had full control and was able to get the Ultimate Touchscreen (UTCA) program authorized (which in retrospect would have required the same thing only it would have been significantly easier, since I would have only had to do one blind click) and Mobizen (which I'm currently using to control it as it's the best and fastest of the three, and oddly it's faster through the web interface than the desktop program).
In the end, what would have made this significantly easier (in fact, very easy), would have been to use a combination OTG/MHL adapter that would allow using the mouse and TV at the same time, or possibly a micro-USB OTG Y-cable so I could plug one connector into the phone and one into a power supply, then plugged the MHL Samsung adapter into that so it could get power that way, allowing me to plug the mouse in to it instead of a USB cable for power. Not sure if that would actually work, but it seems like it would. Hopefully somebody finds this info helpful. From now on, I'll be installing and authorizing TVQS, Mobizen, and UTCA on my phones when I get them.
I have the same problem. I cannot access ADB in anyway, even in in Clockworkmod recovery. USB Debugging is off. I am on the original firmware that came with the device, (Pre Knox) and the device is rooted.
My lock screen is just the simple lock, with no password required, but I have an app installed that switches the USB mode to Mass Storage for the external SD only so I cannot see internal storage.
MHL does work, but the touchscreen is not working, so all I can see is the lock screen.
When in recovery, ADB Devices shows the device as unauthorized. If i go to option # 3, (which apparently is Factory Reset) the status changes to "Sideload." But I still cannot do anything.
If no one has any suggestions. I think i'm going to have to purchase one of the Samsung Smart Docks.
I can't post links or pictures until I get 10 posts, but this works;
goo.gl/PR7TCK
Other than getting the dock, the only other way to do it that I know of is how I described above, switching back and forth between video and mouse, which sucks because you're flying blind. It requires a lot of patience.
Hello, I have a Galaxy S4 i337 running 4.4.4 Kitkat. It is stock rooted. I have broken the screen and digitizer, so I cannot see what is on the screen and there is no touch input. The phone has a pattern lock with a backup pin. I know the pattern and possibly the backup pin, but I can't input them due to no touch input and I can't see the display. I have an MHL connector that shows the display on my TV, but I can't provide any input. I also have a USB OTG cable and a mouse and keyboard, but input with these devices is essentially useless since I can't see what's on the screen at the same time.
I was going to try the "Android Control" Windows app that I found here at XDA, however, I am unable to unlock the phone and then allow the PC to connect to the phone using ADB. I am referring to the "Allow USB debugging?" prompt. I believe USB debugging is enabled. Wifi is turned off, and bluetooth is turned off. I was thinking that I may be able to connect a bluetooth mouse and use the MHL adapter at the same time, but I can't enable bluetooth. I do not have a Samsung account, so I can't use the find my phone or whatever it's called to unlock it. Does anyone have ANY ideas of what I can try to gain access to the device? :fingers-crossed:
I'm sorry to hear that. I did the same thing trying to replace the glass on my phone. I'm sorry to tell you but you're going to have to go on to Amazon and order one the cheapest I found was for $77. I don't think there is any external application to unlock the pin pattern on your phone without being able to use the touch screen

There has to be some kind of back door or something. Surely Google isn't so inept that they have locked down MY device to the point that I have lost ALL of my data due to the lcd and digitizer being broken. Samsung Kies says that it isn't compatible and says to use something called Smart Switch, which won't work with the phone locked. I can presumably install software via the Google Play website, but that's the only thing that I am aware that I can do without operating the phone directly. I read about an app that can supposedly unlock your device if you install it from Google Play. I have no idea if it works, and that would only solve half of my problem. I still need to disable or bypass secure adb. If not for secure adb, I'd likely have full access to my device. Thanks Google; secure adb is awesome!
Ideally there would be an app that could be installed via Google Play that would automatically enable an FTP server on the device without any configuration. It would be preconfigured with the options in the documentation and would enable on install or after reboot. I have Filezilla and have used FTP before with the device via ES File Explorer, but I can't enable it with a broken lcd and digitizer.
There is a product called Samsung Remote Client/Server that I believe is intended for carrier unlocking devices. It is a paid product, but a free function of the software is the ability to bypass pattern lock. I can't get it to work though. It says:
"Opening Modemport at COM3"
"Bypassing Pattern lock...Please Wait..."
"Bypass Failed"
"Make sure you have set the correct modem or uart port as modemport!"
I have no idea what it is talking about regarding the port.
I read something about possibly being able to manually add my PC's RSA fingerprint to the device to allow adb to connect, but I can't access the filesystem to do this. As much as I despise Apple, I'm wondering if my data would be forever lost if I was using an iPhone and my screen broke. I'm betting either iTunes or one of the Apple stores could recover my data. I guess with Android, you're hosed if your device malfunctions.
Try sending an email to Josh at Mobile Tech Videos or give him a call. He has a shop in texas, and is the most knowledgable person on Galaxy phones of anyone I know outside of Samsung. You might be lucky enough to talk to him in person. (He's very busy.) He can probably get your data for you, for a reasonable price, and will also probably be forthcoming with any way you can do it yourself, if you ask. He is somewhat active here on XDA-Developers as @connexion2005.
Edit: I hadn't looked at his web site for some time. That note about not taking new orders has been up there for the better part of a year now. Also, it looks like he is making good money fixing blacklisted phones with his jtag equipment. So, I'm not sure if this is good advice or not. But it can't hurt anything to ask.
Thanks for the information. I'll look into it. I may have found a broken Galaxy S4 with a working screen and digitizer. If that pans out, I think I can connect the screen and digitizer from that phone to my phone and at least unlock the pattern and authorize my PC. I also found a dock on Amazon for $16 that supposedly lets you connect an HDMI cable and mouse and keyboard simultaneously. I'll try that if the other phone doesn't come through.
OTG cable
Use a generic OTG cable, then connect a wireless Keyboard/Mouse combo. I use one of these: Logitech K400 for my customers, works for most phones.

I appreciate the input and suggestions, but as stated in the OP:

I have a semi-complex lock pattern. Using a mouse to input the pattern without being able to see the screen is virtually impossible. I have tried. Just getting it to accept the WRONG pattern 5x while hitting at least 4 points each time is very frustrating and nearly impossible. Unless the trackpad on the keyboard you linked works differently (touching the center of the pad centers the on-screen cursor), that method won't work. I doubt it works that way in my experience with laptop trackpads. The only solution that I know of regarding OTG would be to buy a dock that enables both HDMI and mouse input simultaneously.
Regardless, someone came through with a broken Galaxy S4 that I can possibly take the screen off of to at least unlock my phone, remove the pattern lock, and authorize my PC's connection via ADB. I'm about to tear into that now.
I managed to get into developer mode on my new NGP, there's no more "build number" as I've seen in several blog posts with the latest update you click on the Nook icon on the About page it takes you to Developer mode. I've been able to install a few apps, but here's what I'd like to do.
I'd like to plug in a USB keyboard and use it to SSH into another machine through my WiFi hotspot to do some HTML/JS/CSS text editing while I'm outdoors (at the pool, the park, etc) as my other laptops/tablets aren't visible at all outdoors with glare. This would be a nice portable solution if I could get it to work, even editing locally on the device through some editor and sending via SFTP would be just fine.
However, I can get my USB OTG cable and USB keyboard to work on my Samsung J3 phone just fine, but not on my NGP it does nothing when plugged in, keyboard caps lock doesn't activate. Is there a way to get it to work, and does it require rooting the NGP? I haven't rooted the device yet.

As a workaround I put a VNC client on it so I can access my other devices and do the typing from there, that way I can use my RPI3 as the system with a keyboard on battery power and do some Python (Django)/NodeJS/ReactJS from the NGP using it as a monitor outdoors, but if I issue the following commands via adb to rotate into landscape mode I lose input on the NGP and have to reboot:
adb shell settings put system accelerometer_rotation 0
adb shell settings put system user_rotation 1
Any ideas?
I believe I looked at this once.
At least one of the problems is that the ID pin on the micro USB connector is not connected through to the processor.
B&N has never shown any interest in putting Bluetooth in a Nook.
We'll have to see if the latest "Nook Glowlight 3" will have either OTG or BT.
Hi,
My brothers phone screen is basically unusable.
When I connect the phone to the PC it recognises it in Windows but the phone contains no folders. At first I assumed it was because his screen was locked so I connected a OTG and keyboard and using commands managed to get his phone "unlocked" to the home screen.
However this didnt fix the issue.
Reading around it seems I may need USB Debugging enabled (if he hasn't already) but due to not being able to use the screen how would I do that?
Do I need a MICRO USB to HDMI & USB adapter to use a mouse and TV output?
Or is there a way I can fix this through windows using ADB?
At this point we are willing to try anything as all we are looking for is some family photos off of it then binning the phone and I don't want to put £100-200 into the screen replacement just to attempt this data recovery.
All help is greatly appreciated,
Cheers
ADB is the door to any Android device. As long as ADB has not been activated on the device - and the related RSA keys got created - you have no chance to pull out data from device, IMO.
Ok,
Well see the fact when I connect it to windows it shows the phone but not the folders inside, and I can only assume there will be a popup on the screen mentioning to ALLOW/DECLINE transfer etc..
If I use the OTG adapter I can plug my keyboard in and use the sequence SPACE, SPACE, BKSPACE, BKSPACE, then my PIN and ENTER and it unlocks to the home screen.
But because I would need the phone connected by both PC and KEYBOARD at the same time is it possible to get a splitter on the OTG adapter and this would hopefully let me press RIGHT and ENTER to accept the message?
If not then can the phone be connected via HDMI to see if any message is infact popping up??

OK, new to this. To get usb debugging on, click system. About phone, Software information, build number. Click that several times. (AT least 10). You will see a message that you are in developer mode. Go back to home screen. Click settings icon. Scroll to bottom you should now see { } Developers optiions. Click that. Find the section for ADB, enable ADB. Once ADB is up and running you should be able to pull the files. The screen for an android is the desktop, mouse, and keyboard. (PC analogy). You need something to see your icons, something to click, and a keyboard. If OTG acts as a mouse, and you can see the basic display, and have an external keyboard. I think you can do this. I am not sure what OTG is .

1. I cant follow that process as the screen is completely destroyed (no display/no touch), thats why I have been blindly using a keyboard to try and find the setting
2. OTG is ON THE GO , its a small adapter that lets you connect USB devices to your phone.
Sorry about that. I think you are stuck. without some visual clues I think you can not put the phone in developer mode. Did you try just a plugin (via usb) into windows and seeing if there is a pictures folder?
It find the phone in Windows, but wont display the folders.
The OTG splitter I purchased to be able to connect it to the PC and KEYBOARD at same time didnt work as it doesnt supply power (should have checked reviews).
Any other solutions? Or is this a new screen for £200 just to get data?
I purchased another OTG splitter that has a OTG/CHARGE switch so this should let me connect it to the PC and KEYBOARD.
Can anyone give me shortcut keys or step by step on how many times I need to press certain buttons to get down to the USB DEBUGGING section please?
I booted my Nvidia SHIELD TV 2019 into the bootloader using ADB. The problem is that I can't navigate the menu. Neither the remote nor the controller seem to work. All tutorials speak of connecting the controller via USB but that's for older shields or the PRO version. This device does not have a USB port to connect the controller or keyboard there. My model is P3430, the regular shield TV 2019.
Has anyone been able to enter into options in this menu for this model?
I'm trying to downgrade the shield from the January upgrade which broke many apps.

You have to use the hardware button on the device located above the hdmi port.
press once to navigate menus and long press to select.

Thanks! I had figured that out but now I'm stuck because I can't run fastboot commands via wifi and the device has no USB connection. Any way to get past that?

That the one million dollar question.
The following is what I have read from various posts in various places:
1. I have read that you can desolder the sdcard reader and solder on a usb port for that purpose.
I have not found a post of anyone who has actually done that though.
2. I have heard reference to being about to use fastboot over network and have tried without success on over wireless and ethernet.
Maybe the update to android 11 opens up more possibilities for this method but likely not.
3. I have also wondered if there could be a way to sneak a copy of twrp custom recovery into the image-shield-2019-atv-9.0.0.zip and use that to do a restore by placing it on an sdcard as described in other posts.
This is unlikely to work and even if it did the next issue is how to navigate a custom recovery without a mouse or keyboard. Maybe using CEC form the tv remote or the power button method.
4. Another option I have considered is to somehow use the ethernet port with a usb adapter. However I think the USB/SDcard Bus are completely isolated from one another making this impossible.
Disclaimer: I am by any means an android developer just an enthusiast of android rooting.
Final Thoughts:
My hope is to open up this conversation. now that a new version is out and folks are maybe playing around with this for the 1st time in a while.
Other places where rooting the Tube comes up the answer is often just get the pro.
But I like the tube. Its been a good replacement for the firestick which a got fed up with. I want a portable ATV device for travel that isn't as underpowered.
