I have a Samsung Galaxy A30S. I added a screen lock PIN code and can't remember it. The airplane mode is activated and I cannot turn it off, cause it's asking for PIN. I don't want to do a hard or factory reset since I have very important memories of photos and phone numbers in it. Please Help.

**Context**, in case anyone believes I'm trying to do this for nefarious purposes. I have a Samsung Galaxy A12 running Android 11. Long story short, two years ago I shattered my phone's screen, I was already planning to change up the phone so, yes I was a little bummed out. Recently, I fixed the screen. I wanted to access some old files that I had in there, but I can't remember the password. It's a fairly long password, so it wouldn't be easy to remember after 2 years. I decided that maybe I can try to recover some videos and pictures, but apparently I didn't have USB debugging on in the past, or maybe it disabled on its own. It should have Dev options on though. I went to recovery mode and tried to mount /system, but it also gives me

failed to open /dev/block/dm-0 no such file or directory
mounted /system

and even after spamming it to the point it just says **mounted /system**. When I type adb pull /data/property/persist.sys.usb.config ~/ it just says adb: error: failed to get feature set: no devices/emulators found I have also tried to switch USB ports, but nothing. Overall, I'm confused, don't know what I'm doing anymore, much less how to fix things.

I am using Samsung Galaxy A14, but it's locked with my password. I need my phone back without resetting it. I have tried my password many times to the point where my phone has been locked for 24 hours. I also have my fingerprints as an unlocking method. However, it only asks for the password. Any idea?

I have a Samsung A13 phone that has been used, but have no PIN code. The phone is turned on, but locked. To reset the phone I need to shut it down, but to shut it down I need the PIN. The battery is at 100%. I want to fix this before tomorrow. (I could turn on the flashlight, so I'm doing that to drain the battery.) This unlockjournal about the A13 mentions that I repeat entering the PIN to get alternative options to unlock the phone. The only thing that happens is that I get a 30 second time out. --- **Update** As @Robert suggested, I could restart the phone after holding Power + Volume Up + Volume Down for about half a minute. Then I could restart in Boot menu while holding Power + Volume Up. Then I did a factory reset and rebooted. Guess what! The PIN is still needed, so this is not a reset to factory settings. Wiping the cache partition didn't make a difference. Samsung knows the phone and expects an ID of some kind. It offers the option to login using a previously used Google account, but what if that is not possible? **Question** How do I reset the PIN?

I have my daughter's Pixel 1 set up with **Family Link**. It should be running Android 10 I believe. Recently I changed her screen lock password via my linked Parent Phone. I forgot to tell her and since she usually logs in using her fingerprint, she didn't notice the change until she had to restart her phone a month later, which enforces unlocking with her password. Unfortunately, I forgot the new password in the meantime. If I see this correctly, - I cannot unlock the phone using my Parent Account after the reboot, right? - Also, since the phone has not fully booted without the initial unlock, I cannot change the password using the Family Link app because that has not started yet. I mean, I can change the password on my, it just doesn't change anything on hers. I tried the suggestion here: https://android.stackexchange.com/questions/214394/how-to-reset-a-kids-forgotten-phone-lock-screen-password , but my daughter's phone does not have Find My Device installed. Any ideas? The last resort would be to factory reset but I would like to avoid data loss. I think I had the phone set up for Developer Options last time I was able to access it. So if there is a way to do it with ADB or something I might try that although I would like to avoid the installation trouble if there is another way. It would already help me to verify whether I am right in assuming that the initial boot unlock runs before the Family Link app or whether I may have made a mistake somewhere else. I am wondering whether something else is going on since the login itself seems buggy (I can enter the password once, but then the phone does not give me a keyboard for a second try, so I need to reboot again).

I have an old (unlocked, I think) Alcatel AT&T-branded phone that I have not used for years. I charged it up and reset it to factory with the Vol-Down + Start and booted. I was greeted with "This phone is connected to an existing email account". I entered the account ...@gmail.com and Google asked for the last password I remembered. I added that in, yes, still had it. After about a minute, it came back with "That email account has been deleted and we need more information." But it does not say what or how to continue. I never deleted that account and actually have never used the email. I had to create a Google account years back when I got the phone. I do not have any other Google (and never will) account, so they seem to own MY phone. How can I get this working?

My child forgot her lock screen PIN and I use Family Link, but I can't figure out how to get into it or reset the PIN through the app. What are my options?

I have an issue where this alleged waterproof phone's power button starts malfunctioning when in contact with the slightest hint of moisture. This is a horrible in combination with the fact that Samsung XCover 5 will start calling an emergency hotline if power button is pressed 5 times in a row. This feature cannot be disabled or mapped to different key. Really stupid decision if you ask me. With my broken phone trying to call ambulance multiple times a day, sometimes even at night, I have been removing its battery a lot. Today after a few restarts I got a notification saying I need to enter phone password to login to my work profile (Gmail, calendar etc). I entered it, presumably wrong, and the login window said to try again in 24 hours. This was my first attempt in that window. When I locked the screen I found out this timer applies to lock screen as well. I need the phone tomorrow. I have access to the Google account the phone is associated it. Is there anything I can do to remove the timeout?

I forgot my Huawei G6-U10 PIN and tried multiple times but couldn’t unlock it. I searched online and found that pressing the Volume Up and Power buttons together should bring up recovery options. However, instead of the expected options, I see messages like “Check SD update pkg exists…” and “Make sure USB cable is inserted!update starting…” How can I fix this?

This is a follow-up question to https://android.stackexchange.com/q/230996/202005 . Basically, I intend to somehow use this command to remove the lock screen: adb sideload customROM.zip But, the customROM.zip should be something like described [here](https://www.isrgrajan.com/how-to-enable-usb-debugging-in-android-using-recovery-mode.html) to enable USB debugging. The problem is, those steps are incomplete: > **Steps to Enable USB Debugging Using Recovery Mode** > > * Unzip the stock ROM. > * Within the extracted folder, you will find the **system.img** well extract it too using Ext4 Unpacker > * Also, extract the **Update-SuperSU.v1.65.zip** file. > * Now open the folder where you have extracted the **system.img** files > * Grab any **.apk** file from this folder and change the extension from **.apk** to **.zip** > * And Copy the **RSA Certificated** to the **Update-SuperSU.v1.65** folder (delete previous files if exist) > * Also, copy the **build.prop** to the system folder located within **Update-SuperSU.v1.65** folder > * Locate the **update-script** file within this folder and edit it using **Notepad++** > * You need to update the **build.prop** file after adding the following line at the bottom > persist.service.adb.enable=1 > > * Next step is updating **SQLite** Database > * Which can be done by adding the following code to the update-script file > sqlite3 /data/data/com.android.providers.settings/databases/settings.db "UPDATE global SET value=1 WHERE name='adb_enabled'" > > Cheers! You have Enabled USB Debugging > Now you can install your custom or stock ROM using ADB – USB Debugging Although the above steps seem **incomplete**, they look convincing that there might be a way to modify a stock ROM to enable USB debugging by: adb sideload modified-stock-ROM-which-just-enables-USB-debugging-and-does-nothing-else.zip Is there any better explanation than [those steps](https://www.isrgrajan.com/how-to-enable-usb-debugging-in-android-using-recovery-mode.html) ?

Imagine I forgot the PIN for my lock screen. Is there an alternative way to unlock my locked Android phone or tablet? Other than resetting my device, and losing any data that was not backed up?

For some reason, I changed my keyboard to Greek, yet my password is in English. I am unable to enter the password to unlock the phone. I can't pair with Bluetooth without unlocking, and there is no option to change the language of the keyboard. The device is a Sony Xperia Z, Android 4.4, not rooted, and using the default keyboard, if it's relevant. Any help is greatly appreciated.

On my CM9 / ICS 4.0 phone, if I incorrectly enter the drawn pattern five times in a row, it locks itself for 30 seconds. I can't enter any more passwords, but I can click the "Forgot my password" button and enter my Google Account password. On my rooted 4.0.3 tablet running a custom ROM, my lock screen is set with a numeric PIN. If I input it incorrectly five times or more, it locks itself and I can't enter any more passwords. I'm not offered the option to enter my Google account password to bypass this, although I have configured a Google account on the device. I want to activate the "I forgot" button in order to enter my Google Account credentials. Is it possible?

My cousin's kid has played with his Samsung A8 (2018) phone and has changed his unlock pattern. So, nobody knows the pattern the child has set. * The phone has no Google account set up * The USB debugging is *not* activated on device before I have rebooted into recovery mode, and entered the option Apply update from ADB: There is a message on recovery screen saying: > Now send the package you want to apply > to the device with adb sideload ... I'm able to see the device by adb devices command: According to [another post](https://android.stackexchange.com/a/197443/202005) , looks like it is possible to use [TWRP for Samsung Galaxy A8 2018](https://twrp.me/samsung/samsunggalaxya82018.html) to clear the screen lock. So, I have downloaded the following apk package: Now I plan to install TWRP on phone by the following command and then follow the [previous post](https://android.stackexchange.com/a/197443/202005) :

adb sideload me.twrp.twrpapp-26.apk

### Questions Now, before doing so, I have these questions: * Is it possible to install *.apk packages by adb sideload? Is there any possibility that it would mess up the phone? * What else can I do with adb sideload to clear the screen lock? * What else can be done with adb sideload to back up the phone camera images and videos without wiping the data? Thanks =)

Recently, I updated my Infinix Hot 20i, and I encountered the following issue. The phone took a long time to update, and upon rebooting, it prompted me to enter the graphical key on the unlock screen. I have a very simple pattern lock that I have not forgotten. However, when I enter the correct pattern, the phone thinks for about five seconds and then says that the pattern is incorrect. If I enter an incorrect pattern right away, it immediately shows an error. Could you advise me on how to resolve this situation without losing my data, as I do not have a backup?

I have a Samsung J3 2016 (without root, USB debugging not enabled and stock ROM if I remember correctly android 5.1.1.), I need my old WA for legal issues. I currently have the screen lock, but I don't remember the password. I tried to access with ADB, but from recovery, I can only use ADB Sideload. I tried to install different versions of aromafm.zip from recovery, but J3 2016 gave me an error, so I abandoned this option too. Any suggestions for me to recover user data?

I've made the mistake of putting an emoji character (❌) in my unlock pin. This usually works fine, but after the last time I restarted my phone, the two keyboards I have installed on my phone refuse to show the emoji keyboard on the lock screen. This makes it impossible to type in my password :( I've got an external keyboard, but after reading some HID documentation I can't seem to find a way to enter this character. I found some solace with the special charcodes \uef00/\uef01, which would allow me to input something, but they don't seem to work; they're mapped to x+shift+alt and space+capslock, but they don't seem have their intended effect, even on another phone I have lying around (although with \uef01, I see something going on at the bottom of the screen pop up, but it doesn't let me input anything...) Do people have any other suggestions? I don't have USB debugging on :(

I have switched on my old Huawei Honor phone after a long gap. On the screen, I have a message stating below > Android system > * User data locked > * Password required after you restart the device > * Some features are disabled automatically for security I have given the pattern that I remember giving when I used to use it, but then it doesn't get unlocked, and it says incorrect pattern. I tried various other patterns, but they didn't work. Can anyone help unlock my phone without losing data?

I can't get into my Motorola Moto G after a factory reset. It is number code screen-locked and Google-locked. I've tried using the emergency call from the start screen already. I'm looking for help using a USB and tablet to get into my phone. I am open to any way to do it too.
