ZTE SmartTab10 asking for password after update - Android Q&A, Help & Troubleshooting

Hello,
I've recently acquired a ZTE SmartTab10 and it was working just fine, after a software update started asking me for password. So it boots up and it says 'enter your password' on the screen. Thing is, there is no password. Empty doesn't work, any password from any of the accounts don't work, and I never even set a password.
While I realize this may be solved by formatting the device (I do have full access to the recovery), the data on the tablet is very important and unfortunately, only copy, so I'd like to extract it before I go ahead and evaporate the OS. Is there any way to do this?
- Recovery is stock
- Vol up + power gives me android logo with FTM in the middle
- No matter how I connect it to pc ('enter password' mode, FTM mode, recovery) PC doesn't see it as a device and I can't access files
Thank you for taking time to read this,
Have a great day!

[Q] Is My tablet Unrecoverable?

So my friend attempted my pattern till it was locked out. i am entering the usernames and password correctly but it says invalid, i am guessing it was because of the lack of the wifi. So i turned to factory reset. but my tablet ( chineese brand. Sanei n77) would not boot to the recovery mode. i tried power + volume (+ and -) with no luck. So i decided to use ADB. but turns out USB Debugging isn't enabled. So the option to do it through ADB also fails.
So what should i do? Any directions from here?
Thanks for any suggestion.
I think you should send it to the manufacturer or to the store so they can do a factory reset. Googled about how to boot into recovery mode on your tablet, but found nothing.
Good luck

HELP phone is dead after encryption, system not starting

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.

NEED! Help on How to pull files using ADB from Recovery Mode !!

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!

Tried to flash stock onto encrypted phone. hits FRP lock when it gets to system.img

Now it won't boot.
Trying to get rid of carrier trash and microsoft bloat.
Yes I should have unencrypted it first. yes I know the password.
It won't boot to the keyboard so I can't input the password to fix it.
(I know both the google android account pass and the samsung one.)
stuck at download mode / use emergency recovery on smart switch. I haven't got a windows pc I'm pushing with heimdall on linux.
Won't even power down. just blue screens. Any ideas thanks?
edit now I've pressed close pc screen (hoping to turn off the screen) and its bootlooping with vibrate. -- ok back to download model.

Question Trying to recover OnePlus 9R LE2100 after Android 12 update

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?
