S7 Black Screen, but Live device. A way to force backup or fix? - Samsung Galaxy S7 Questions and Answers

we have two S7's, non-edge, and they have been almost bulletproof to now. I have a rooted S5 but have not modded either S7. My wife dropped hers, no breaks in the glass but it came up black after briefly displaying a partial image.
I can force reboot it, and it works. the backup 'key' lights up at times, the LED's work, and the phone receives calls [rings] but of course we can't see a thing.
Is there a fix? I've tried the reset via Vol - Power, that works to restart but no display. I've done Vol+ Power, can't see a thing. Tried Vol - Pwr Home, can't see anything so not sure what the result was. Plugged into PC but without being able to grant permission on the device, no dice.
How can I force a backup of everything? or... it may be backed up to her google account but how to reach, sans S7 display?:silly:

Hi, you can try to access the phone via samsung find my mobile website. You need internet connection at the s7 working and the logon data of your samsung account. In find my mobile there is a backup option.

Fabulous! Going to try now

Oliver, unfortunately she never setup a samsung account period. hard lesson.
Surely the forensics community has a way to get to the stored data.... I guess/think the only things missing, that were not on SD card or SIM, would be a few pictures stored in default local memory, a few downloads, and things that will not be restorable easily like Calendar entries [and a whole lot of app cache stuff that is not high value]... am I wrong?
But then there is the security aspect; even if I cannot fetch usable data, I need to nuke it all... Is there no way to mount those volumes on a pc or other? A universal "nuke everything on the blind" approach?
thank you for your help

I have also black/blank screen but all audio works, hardware buttons work. I can tap the screen and it makes a sound. Voice assistant turns on for some reason and she verifies the touches I make to the screen. She also verifies I am pressing on screen buttons. I also know this because I can turn the phone off using the power button, then on screen buttons, even though it's blank. So the screen does work, just noting visually. I have tried the power + volume down to no avail. I believe the battery has totally died as was also recommended. If anyone has an idea of what to do next...please help.

, I believe, and I'm going to try today, that we can get in Via download mode. So we'll set up adb, set the "blind" s7 in download mode and see if I can browse the file system

[Q] Factory Wipe w/no screen

My screen will no longer turn on and I'm getting a replacement from amazon. However I have a lot of personal data on my unit. (saved passwords, pictures, and access to my home pc) Now like any sane person, I don't want that in the hands of people I don't know. My question is this, how can I do a factory reset / delete all user data with no screen or way to access the menus.
I do have the charging / usb cable, a max OSX Leopard, and a Windows Vista pc.
Thank you all in advance for the help.

ok, so I did another search or two just to make sure I didn't miss anything. I still can't find an answer to wipe all user data when I have no screen. The screen is totally unresponsive, no image displays no matter what I do. I can't go to users/settings/reset, I can't remove during boot loader as there is no way for me to know what is going on.
Think of it like this, If you turn your computer on but leave the monitor cable removed from your video card. Can you hit esc or f12 or whatever during you boot up cycle....no cuz you can't see when and where to do it.
(sorry if I sound angry, very bad day at work and spent a lot of time trying to fix this issue on my own.)
What about connecting to your computer and nvflashing a stock rom. Or at least deleting some files and or folders...
First of all, **** the one linking search thread. Second mate i would connect it to tv with mini-hd, if that is an option for you.

For your personal data, you could use adb to wipe /data and the sdcard. I'm guessing that you don't have root, but I think you could temp root your TF with gingerbreak. You mightnot need root/temp root just to wipe data.
I think the hardware factory reset will erase everything for good measure, but adb woould be my preference.
For hardware reset: turn TF off. You might have to hold the power button down for 20 seconds and release to force a shutdown.
phold volume down and press power button. release power button and wait at least 5 seconds, longer is probably OK. press volume up and wzit for the magic to happen. It will probably take 15 mins. Admittedly, the hardware reset will be tough because you won't be able to see what is happening, but you could use adb to confirm that it worked.
good luck!
I had a similar problem. Used Android Screencast to view the ouptut on my PC. Unfortunately, even though it was rooted the remote input didn't work so I had to guess where on the screen to tap.

Fighting a lost cause?

I've got a rooted (Super SU, but the original root manager was Superuser) LG C800 that I was having problems with. To be specific, I installed some apps on to the system. Some of these apps would be Titanium Backup for root, Avast Mobile Security, ROM Tool Box Lite, Super SU, and a quite a few others. From day one they seem to be kicked right back to my S.D. card, but not all at the same time, and some would stay on the system. I read where I should move the apps back to my S.D. card and try to re-install them on the system minus the data. When I did, the phone went nuts. Now it stays in a restart mode but never fully boots up. Can I salvage it, and if so, please tell me how?! I have tried the hard reset/recovery boot where you hold down the power button, volume, and a few other keys, but it did not work. I'm a broke college student and can't really afford to buy a new phone. I used this one for everything including tethering it to get my assignments done at home and turned in on time. Please help! I'm open to suggestions....... My phone will be completely off. When I plug it into my computer, via U.S.B., it automatically turns it on whether I want it to be on or not. Then it starts off in "reboot recovery" mode, will boot all the way to the point to where the home screen would normally turn on, but then it starts in that "boot loop" all over again but never fully boots up before going back to the beginning of that "boot loop" yet again. I can't even get it to register on my laptop as being plugged in. The reason I took the apps I placed on the system off was because sometimes when I'd re-boot the system the apps would be on the system and sometimes back on my S.D. card without my involvement of any kind other than rebooting my phone. Is completing a Nandroid recovery or re-installation of my ROM even possible with my computer no longer recognizing it as even being plugged in? From what I can tell it won't be. Am I fighting a lost cause or is it salvageable?
Rooted myTouch Q 4G, a.k.a. LG C800
I believe it has a 2.3.4 GRJ22-perf, and then something like 2.6.35.7? I can't remember off the top of my head, and I can't pull it up on my phone anymore or else I'd double check.
Have you tried booting into recovery?
(More about my phone from the original post) Honestly.........I'm not what you may consider technologically inclined. I have however done about as much research online concerning this matter as any one person can do. I've looked it up on all major sites, and many smaller ones too, that post remedies for phone, or "human" if you'd rather, malfunctions. They all talk about still being able to reach a home screen or doing the whole holding the power and volume decrease buttons until I "reboot recovery" screen appears (if that's what you're referring to as doing a recovery reboot as). Don't forget the one where you hold hold the power and volume decrease buttons along with the "A" and "F" keys as well. I even tried one from here where you're supposed to push the genius button after the Android figure leaves the screen. My phone won't allow me to do either. Basically if it's online, I myself, or this girl that's been staying with me, have tried it without any results. On the initial boot the Android figure and the box with the arrow coming out of it show up and it boots until just about the point that it use to switch over to the home screen and it will start the whole "boot loop" over again. The thing is though that the Android figure and box aren't there any other time after the first boot, and with every boot loop it makes after that, the time is reduced from the beginning of the loop to the end when it starts all over again. The phone won't shut off unless I remove the battery and even though my laptop no longer recognizes the device, when I plug my phone into it or another power source and it's off, it automatically turns itself on and begins that boot loop all over again. there is one thing I have yet to try. I read on one site where I could download a custom ROM on my S.D. and then try reboot it, but it never makes it to the point in which the files on my S.D. card are ran, much less scanned. I am still 100% open to any and all suggestions in the diagnosis of this issue. I may record and place a video on one of the more popular "tube" sites to better show or further explain what's happening and then come back on here to post the link?! Feel free to reply back if it's possible you can help before I'm able to complete that later this evening. And thanks for any and all help in advance to everyone.

[Q] Samsung Galaxy Tab 2 10.1 Hacked, Touchscreen unresponsive

Samsung Galaxy Tab 2 10.1 Hacked, Touchscreen unresponsive
Hi! I need help with my tablet.
Device: Samsung Galaxy Tab 2 10.1 Tablet, model GT-P5113 TS. This model doesn't have a way to yank out the battery.
What's wrong: Touchscreen is not responding.
Current state: Attempting to drain the battery. Doesn't appear to be turned on. Factory reset apparently performed.
What happened: Sorry, this is long. It is as best as I can remember it. It may be somewhat inaccurate.
Yesterday evening, I was on my Windows laptop and logged into my Google account. I *thought* I used the Google Play Store to install Chrome to the tablet. (I had looked at the html5test website and it said Chrome had a higher HTML5 rating than the Dolphin/Jetpack browser I've been using on my tablet.)
But something went terribly wrong.
After sending Chrome to it, I unlocked the tablet and used both Chrome and Dolphin to go to html5test website. They both scored the same or nearly the same. I don't know if any of that is relevant, but I'm including it just in case.
At some point after that, I woke the tablet with the power key and used my unlock pattern on the dots lock screen.
That's when I saw what I believe was mal-ware in action. The settings menus were scrolling and sub-menus being selected, all by themselves. I couldn't say exactly what was changed because whatever program or script that was running the process was going extremely fast.
When I realized it might be trying to send out data over my Wifi network, I turned off the Wifi router in my home.
I repeatedly held down the power key to turn the system off, but doing so only rebooted back to the useless lock screen which was not responding to anything. The normal method of holding the power button for a few seconds to bring up the menu and then tapping the "Power Off" option on that menu refused to power off the system. Nothing on that menu responded to touch.
Entering my pattern on the lock screen did absolutely nothing. I didn't even see any lines traced when I ran my finger over the screen.
At some point, I pulled out the external SD card. I have no idea if whatever hacked the tablet also put a copy of itself on the SD card.
I called a friend who looked up how to restore the tablet to factory settings. I didn't understand the directions exactly, so I ended up on a screen with a Warning!! about installing a Custom OS. (Holding down the Power + Volume Up seems to get me there)
I left it on this screen, and I turned my router back on and using my laptop, contacted Live Chat at Samsung but they didn't understand my problem. They told me to reboot the device and swipe my pattern several times and then after several failed attempts I would have the chance to use my Google credentials to get into it. But the device apparently never registered that my swipe attempts were failing.
So my device was booted up with me locked out, with the WiFi router on for a little while again. I turned off the router as soon as I realized that. That disconnected the chat session, but since Samsung chat wasn't helping me anyway, I didn't bother trying to go back.
I got the device back to the "Warning!!" screen. Then turned the router back on and searched for how to do a factory reset of the device. I found a video on YouTube and followed it.
I pressed the Volume Down and Power buttons simultaneously, followed by letting go of the power button. That brought up a menu which contained several options, including an option to do a factory reset. I used the volume buttons to highlight that and pressed Power key. A second screen came up and I used the volume buttons and power button to select "Yes" to confirm the reset.
It appeared to have done a factory reset, rebooting eventually.
However, after that, when I tried to tap on the touch screen to move forward through the selections, the touch screen was still unresponsive!
So I brought back the "Warning!!" screen and ran the battery down until the screen was blank and it wouldn't start when I held the power key.
Then I charged it for about 20 minutes and rebooted it. I think when it came back it was on the Recovery menu. I think I did a second factory reset, but not 100% sure. It eventually rebooted after a lot longer than usual.
When it came up, it was saying battery was low. I tried to tap the OK button, but nothing happened. Behind the battery window was the first setting screen to set up the device for the first time after a factory reset. (I think selecting USA?)
I brought back the "Warning!!" screen and left it on overnight so that the battery would run down.
That was about 8 hours ago. When I woke up, I used clear tape to keep the power button pressed down, to ensure that the battery will continue to run down.
____________________________________________
What do I do next? How do I get the touch screen to start working again? It is not a hardware problem, unless mal-ware can break the hardware. The touchscreen had been working fine until this happened.
Should I take the tablet back to Best Buy where I bought it at least a year (maybe 2 years) ago? I don't know if it's still under warranty.
I have over 20 year of experience as a software developer, but not for Android. I am not very experienced with doing anything to hardware.
Should I try to fix it myself?
I have never rooted any Android device and I'm not sure what that means, either.
I've never re-installed the ______ ? (rom? image? Odin?)
I read on this and/or other forums that there's a way to replace something, but the instructions were beyond my level of understanding. I would need the procedures to be broken down into steps which don't assume too much about what I know.
I understand how to download a file to Windows, given a URL for it. I understand what a zip file is and how to extract it. I understand how to press hardware buttons and plug in cables, and do these steps in the order I'm told.
I don't understand what I'd use to get the downloaded whatever-they-are onto the tablet to replace whatever-the-other-thing-is so that the touchscreen works again.
As far as I know, Odin is a Norse god.
The only firmware updates I've ever done are the ones that the device does on it's own through Samsung's updates.
I'd deeply appreciate getting this device back since I have extremely limited funds and probably won't be able to buy a replacement.
Thank you,
Linda

Definitely sounds like malware. You have two choices that I see, either root and custom rom or flash back to stock. Since you are stock you'd just be overwriting your existing install. Read this thread and decide your course of action http://forum.xda-developers.com/showthread.php?t=2203309

[Q] DESPERATE HERE: Phone won't boot after soft reset?

A couple of months back I decided to root my device. I did this using the unlocking the bootloader method. As a result, I lost my DRM keys, and I managed to restore DRM function by following the methods detailed here: http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
I had to download the stock Android 4.4.4 from online, which I flashed my phone with - no problems. Things ran smoothly from then for about a month, and then I realised that my cellular network started to malfunction, and I couldn't access apps like YouTube and Snapchat on the cellular network. This prompted me today to do a "soft reset" of my phone, by holding the power button and volume up button simultaneously for about 3 seconds - under the impression that it would restore my phone settings back to the factory default.
Much to my horror, the worst case scenario happened. When I performed the soft reset, my phone vibrated 3 times and switched off. When I tried to turn it back on, it would show the boot-up screen indicating "SONY", followed by the next screen indicating "powered by android", and then it would show the blue screen with the wavy lines. It stayed on this screen for about 20 minutes. I figured something was wrong, and I tried to soft reset it again, only to be stuck at the blue screen once again. I decided to let it stay that way for 2 more hours, in order to drain the battery. When the battery drained, I turned it back on, and it was still stuck at the blue wavy screen.
I don't know a whole lot about Android phones, and I have no idea why this is happening, but it is causing me an immense amount of frustration - I have invaluable data on that phone, and to lose it would just be devastating. I can't even begin to describe it. I'm using TWRP recovery, and I'm also using TitaniumBackup which is backed up onto my phone's internal storage, and I can't access any of the files on my phone from my computer, because it doesn't recognise my phone.
This has been a long one, thanks for bearing with me. I've got a few questions:
1. What's the problem that's preventing my phone from booting?
2. How do I fix it?
3. If it's unfixable, how can I retrieve my data from my phone?
Really, really hoping someone can help me out on this - I'm completely lost and am desperate here. Thank you in advance!
Can you boot into TWRP's recovery mode using the volume down key?
Just press volume down when you see the green light on your notification led upon powering on your phone
Well something keeps the phone to boot, try to clean cache in recovery, it might help.
But to restore data on internal storage, count it as unpossible.

Pulled sim broke screen? Can't do anything

Heu guys,
So I received a P30 as a gift yesterday, it said it had an update so it downloaded. Then it said it needed to be at 20% to install the update so I just left it until later when I could get to a charger. The thing is, I also didn't have a sim card in it.
I pulled the sim slot with the phone turned on (install pending) , and as soon as I did that I got a new black screen of death, nothing like in any of the videos online.
This one allows me to interact with the screen, however the entire screen stays black except for about 50% of the top (like I can see 50% of the battery icon) notification area. The tiny section of the screen that turns on also looks sorta wonky, like screens often do when they get water damage.
I've been able to turn it off, by guessing where the power buttons were. I *think* I even got it to the hard reset menu, but not being able to see, I can't type on the screen. It does react to the soft reset (power + volume down) but when it turns back on, it won't even show the logos on boot, everything still stays black minus a section of the notification bar.
Is there a way to do a hard reset without being able to interact with the screen at all? Can I do it using my computer somehow?
I know the screen is not broken because I can interact with it. Also on 1 of the 30 soft resets I did, the screen flickered some sort of error message for a quarter of a second, so fast all I could do was see it was text.
I'd just return the phone but it was a friend's old work phone and there is no way to get a replacement.
I recommend you to use Hisuite on a computer, try to connect the phone (I said try because you must select the type of connection on the phone). If the phone connects to Hisuite, use the recovery option to reinstall the default firmware. Good luck!

this might be my only option. I was trying to find something just like that. Couldn't figure out if there was a software for it or not. Thanks will try when I get back to a computer tomorrow!
