To start off, I suffered, what seems to be a common problem, of the fingerprint unlock on Samsung Galaxy S6 Edge randomly being unable to recognise my fingerprint. Followed by my back-up password not being accepted. Unfortunately, I turned off my data and wifi before the phone locked so the problem doesn't seem to be able to resolve itself unless I Factory Reset the phone.
This i am happy to do as long as I can find some way to retrieve the media files from the phone (just pictures and videos). I read up and watched some videos where some people were able to use ADB through Recovery Mode or Field Test mode, and pull the files from the phone. These people however were using older models of Android phones but I decided to read numerous pages etc and go ahead and try.
I set up everything (I believe) i needed on my Mac Book pro in order to use the Adb Terminal. However when I tried to connect my phone Adb couldn't detect my device. I then decided (after reading somewhere to do so) to press "Apply update using ADB" on the Recovery menu. Again, Adb did not detect my device.
i left this screen up on my phone which resulted in "dm-verity verification failed..." appearing at the bottom of the screen. It then switched back to the Recovery menu and continues to show "dm-verity verification failed..." at the base of the screen. Now when I try and power up the phone normally, the start up screen just repeatedly flashes and it goes no further than that.
Im not completely brain dead when it comes to this stuff but I obviously don't fully understand what I am doing, So Im wondering if there is a genius out there who, even after what I've done, can help me pull the files from my phone before I have to Factory Reset!

LG Escape running 4.1.2
here is the progression of events:
1. rooted device
2. root seemed successful and no malfunctions
3. backed up all apps and system data with Titanium backup
4. the lg escape has no way to unlock the bootloader, so I tried various other methods. one of which was entering recovery mode via terminal commands. this is basically a hard reset, and it wiped all my data
5. I restored all my apps and data from my external sd card with titanium
My best guess is this is where something went wrong
6. upon restoration it prompted me to reboot the device
7. reboot passes manufacturer logo, but resets when AT$T logo appears
8. as stated earlier, there is no way to enter recovery mode during boot.
9. there is a hard reset during boot, but mine will not work, as it requires touching buttons which do not seem to be active in my stage of the boot sequence
so, I understand this does NOT mean my phone is bricked, but I don't know how else to get it to boot back up, or what is even causing the boot loop, as I DO NOT HAVE ANY CUSTOM ROMS flashed. any help here is very appreciated!
EDIT: so I have attempted to use adb on my pc to reboot into recovery from there, but it occurred to me that while I was in recovery the first time, I never checked "usb debugging". as a result my adb console commands cant even see my device. any way to turn on usb debugging while locked in a boot loop?
also, I can get it to enter download mode. I was hoping I could just reflash the firmware to it without needing to enable usb debugging, but have no clue how to do that while locked out of the phone.
I realize this is a very specialized set of questions, but it is necessary to ask here as the most people will see it. im open to any ideas

i have now tried to flash the firmware while in download mode using a less than legitimately obtained lg R&D tool. however, i need V10F_00.kdz and i am facing a bit of censorship. any kind soul willing to host this file on dropbox or similar so i can download it?
Usually devices have a button combination to press when powering on to get into different modes. Maybe try searching for the button combination of your phone on Google? Try ' lg escape button recovery ' ?

believe me i have. the only combo i can get to is download mode. there is a combo for a hard reset, but my touch buttons arent active during boot.
Hi, I got Motorola Moto G, original system, no root. I just encrypted my phone, process most probably finished without problems - I stopped watching the phone on around 90%. Then it restarted, boot animation, "enter your password to decrypt the phone", I type it in, green robo shows for 1 second and then black screen (backlighted) :/ After couple hours nothing changes.
If I type wrong password, phone ofc doesn't acccept it. Computer sees device, but I can't access it. When I turn off the phone by pressing POWER for long time, it just resets and goes back to asking for passwod again.
Please help me recover my data...
EDIT
before entering password PC says phone is off, after typing it, PC says it doesn't have drivers (it worked normally before encryption).
EDIT 2
I can enter fast boot, but IDK what next. Recovery mode just ends with "NO COMMAND"
I see that probably all users who got this problem have Motorola Moto G too. Mostly people who use CM and tried to encrypt phone.
I downloaded Android SDK, fastboot.exe tool sees my phone in this state. Not sure if it can be used to do something useful....
adb.exe doesn't see device
Cyanogenmod is very buggy and in perpetual development state, not recommended.

Thanks, but I got stock Android and I don't want to loose my warranty :/

So, I left the phone in black screen step over night. Battery ran out. I tried turning it on/off, entering fast boot mode, but nothing happened, then connected to USB. LED turned on for a while, screen too, showing battery with 0%. But now nothing again. Just black or off, not sure. Can't do literally anything, I tried pressing different keys for minutes and changing USB slot.
EDIT
nevermind, fixed battery problem, Moto G with no power needs normal charger or much longer time on USB
From what I've read, encrypted data on phone is protected by password and some kind of encryption key/file. Reflhasing firmware would cause permanent lose of that key and thus whole encrypted data.
The only solution I guess is copying that key on PC. Copying encrypted data if possible, and decrypting on PC using some tool, as Android is open source, so it shouldn't be a problem to extract it's decryption mechanism and run it on PC.
OR copying key to PC, reflashing phone, copying back key and praying this time system will start.

The problem is, that you don't have the ability to use adb pull through the stock recovery. This kind of thing can only be done via a custom recovery like TWRP, CWM, or Philz. Now that it's not booting, pretty much the only thing to try is to install a custom recovery and boot directly into it before it tries to restart. Make sure you find one for the correct variant of your phone. If yours is a VZW or ATT version, you're in trouble because they don't have custom recoveries like that for them.
**The problem as it stands**
My Galaxy S6 Active is stuck in a sort of bootloop, except it never seems to attempt a boot. If it was turning on, without any combination of keys, it would go to the "No Command" screen. From there all I can do is force reset (power + volume down) to get it to restart to the same place or as it displays the Samsung splash screen, press volume up + power + home, it goes to the download screen. From the download screen, I can use my pc to flash a rom (that may not be correct) to the device and according to Odin, that is a success but my device freezes on "erasing".
Imgur album with pictures of the accessible screens (http://imgur.com/a/Rd9ND)
**Description of the problem when it was booting**
At seemingly random times, the device would freeze and the only way to get it to do anything was to reset it. Sometimes it would enter a bootloop but through key combinations, I would be able to get it out. One time after a bootloop, I had the sense to back up the device's storage, so luckily I have that.
**What I've done**
- I have tried wiping the storage in device recovery -- when it was accessible, I can no longer get to it.
- I have tried using Kies/Smart Switch emergency software recovery -- but when provided with the model name and serial number they would both crash.
- When the device booted, I tried using the standard recovery feature in Smart Switch. I can't remember the exact message but it was something along the lines of "This device does not support initializing"
- I have tried using Odin to flash ROMs (again, I may be using this incorrectly) to the device. I have only tried Samsung release ROMs, meaning ones that have not been modified by a 3rd party. I followed the second and third methods of a guide on XDA forums (https://forum.xda-developers.com/ga...e/downloading-flashing-att-galaxy-s6-t3260744). Odin never throws an error and it always says it was successful. During the device's initialization with this new ROM, it gets to 32% then goes to "Erasing". A few seconds later the animation freezes. I can leave the device here for hours but nothing happens. So I believe more than the animation is frozen.
- I tried using ADB recovery via the device's recovery mode (when it was accessible) but from what I can gather, Samsung uses a proprietary ADB interface that would not work with what I was trying to do (I was following method 3 of the previously mentioned guide (https://forum.xda-developers.com/ga...e/downloading-flashing-att-galaxy-s6-t3260744). I would always get a message saying "ADB server out of date".
I may have done more than that but that's what I can recall.
Any help would be appreciated. Even if you know of a better place to post this, let me know.
Thanks
My s6 active did the same thing on 08/24/17. I have not yet found a solution.
I did the infamous update to Android 12 yesterday and this morning tinkering with the new settings I accidentally blocked myself out of my phone.
Before testing yourself I want to give a warning to not you bother to try this setting on, just in case the same thing happens to any of you: it was a setting called "Quickly unlock screen without password" or something like that, it was in Settings > Privacy & Security > Lock screen Password. If anyone that still has the Android 12 update installed would be so kind to share some screenshots of those steps I could tell right away which option was the one I activated, since I can't even access my phone anymore...
Don't know why, but it seems that with this option the system just tries to fill the password but it always fails and it just keeps vibrating forever and can't do anything at all. The only time it stops is after rebooting into the SIM unlock prompt, but after unlocking the SIM it starts vibrating again and can't even input my password.
After this now I'm trying to recover all my stuff from my phone before doing a factory reset, which seem inevitable at this point. I have tried to access mass storage from Recovery Menu but it doesn't seem to be recognized by my PC. I have seen that OnePlus devices have different recovery menus, this one has a menu with four options (Format data, Reboot device, Power off and Advanced) and at the bottom it says "Ver 1.2", which tapping on it twice gives a message telling to go into Download Mode, but it doesn't seem to do anything aside from rebooting.
Also tried to go into Fastboot from the recovery menu (Advanced > Reboot into Fastboot mode) but it just shuts down instantly after the Fastboot logo shows up.
So, please, could anyone give some advice here? I'm pretty much lost at this point and I don't want to factory reset right away just yet. Any help will be appreciated.
are you able to fix your phone?
