Enter Password to Unlock 30/30 Attempts Remaining Error (Full Fix Guide)

Are you facing trouble on the “Enter Password to Unlock (30/30 Attempts Remaining)” page and unable to enter your Android phone’s password? Don’t worry, because there are numerous options you have that will help you get out of this situation.

Although it might seem like you will lose all your data because of this message, there are ways to unlock your device. All it takes is knowing which method works best for you without triggering any data loss.

In this guide, we will show you 10 methods to resolve this problem with ease. We will also explain what causes these issues and how you can avoid them in the future.

1. The Science Behind the “Enter Password to Unlock 30/30 Attempts Remaining” Error

“Enter Password to Unlock 30/30 Attempts Remaining” is the name of a security protocol for Android devices. This security protocol comes into play when the system prompts for a password to authenticate the user’s identity, and by that time, fingerprint or face unlock is disabled.

Due to the use of encryption on the Android OS, along with security measures such as secure startup. To access the encrypted data and gain entry, you need to provide the password, nothing else.

Why does this error appear?

This message may appear for the following reasons:

• Someone entered the wrong passwords several times
• Restart the device that asks for the password
• If Secure Startup is enabled in your device
• System crash or reboot
• Interference from third-party lock screen applications
• Incorrect settings of the time/date

Additional Cause: Second-Hand or Used Phone

This problem occurs quite frequently in secondhand Android phones, particularly the old LG handsets.

If the prior owner of your phone does not unlock or reset it before you use it, the phone will still ask for a password.

• The device has not been wiped properly before being sold
• The password from the previous owner is still needed
• Someone can still enable Factory Reset Protection (FRP)

What this means:

You cannot unlock the phone with any other credentials. It simply means that your phone is currently locked for security purposes, not because there is anything wrong with it.

2. Why LG Phones Are Most Affected (FDE vs FBE Explained)

This problem is much more prevalent in older LG devices, such as the LG G6, G7, G8, and V35, that run Android 8 or 9. The reason behind that lies in the type of encryption used.

2.1 Full Disk Encryption (FDE) on LG Devices

All older LG mobiles running Android 9 or earlier use FDE.

• The whole storage of the device is locked from the time of booting
• Can only load user data after providing the right password
• Post-restart, the phone first needs verification of the password

That is why:

•  Enter Password to Unlock (30/30 Attempts Remaining)” appears directly after rebooting
• Both fingerprint and facial recognition are disabled
• There is no option without the right password

In other words, with FDE, your mobile device is locked until the verification step is passed.

2.2 File-Based Encryption (FBE) on Newer Android

Instead, contemporary Android smartphones utilize File-Based Encryption.

• Just fragments of the information are encrypted right from the start.
• The system can partially boot without complete verification.
• Can perform several functions before the device is unlocked.

As a result,

• The frequency of total lockouts on newer mobile devices is lower.
• More recovery methods are available for users.
• The lock screen’s functionality is not limited.

Key Takeaway

All information stored on older LG mobile phones with Full Disk Encryption is fully encrypted and cannot be accessed without the password. 

3. What Happens After 30 Attempts?

If there have been numerous attempts to unlock the password, the Android operating system guarantees complete security against further attempts.

In case the maximum number of trials (that is, 30 attempts) has been made, one can exercise the following options:

• Temporary locking of the phone
• Delay before every attempt
• Full lock until inputting the right password
• Data wipe automatically (only if the data wiping feature is selected)

4. How to Fix “Enter Password to Unlock 30/30 Attempts Remaining.”

Want a smarter way to handle device lock issues automatically?

Manual fixes don’t scale. We help businesses build AI-driven automation systems for device management, security alerts, and recovery workflows. 

Fix 1: Wait for the timeout

The system will lock out the user if they repeatedly try to use the wrong password to access it.

However, it is advised that the user not attempt to determine the correct password. On the contrary, the user should relax, take it easy, and allow themselves to be locked out first before attempting to use the correct password. It takes a few seconds to a minute.

Fix 2: Enter the Correct Password

While it may appear to be an extremely easy fix, errors can occur when typing the correct password. Before attempting any of the methods, the individual should be patient and try entering their password. It includes making sure your Caps Lock is off during typing. This is to make sure that you type everything correctly, including letters and numbers in the correct positions. If there was fingerprint recognition before, keep in mind that you will be required to enter your password after restarting your phone.

Fix 3: Use Backup PIN

The Backup PIN may also appear in the list of unlock options on some Android phones if the device passcode is forgotten.

Once you see the “Back UP PIN Unlock” option on the lock screen of your mobile phone, tap Backup PIN and type the PIN code that you have created earlier. Once done, you will be able to create a new passcode for your phone.

Fix 4: Use Your Google Account to Unlock

Your phone might display the “Forgot Password” option, which you can use to reset your password with your Google account. While this fix may work with most old Android versions, it doesn’t hurt to try it.

Go ahead and click the “Forgot Password” option that appears on the lock screen. Now enter your Google account details to authenticate. Next, you can reset your password on the lock screen. Lastly, you will regain access to your phone after changing the password.

Fix 5: Use Find My Device

If you’re unable to unlock your phone directly, you can use the Find My Device service on another phone.

Just launch any browser and log in to your Google account. Select the device listed below, then click Erase Device. This means that all the passwords on the lock screen will be removed. Please keep in mind that this solution will erase all the files stored on your device.

Fix 6: Use Samsung Find My Mobile (No Data Loss)

If you have a Samsung phone, you can unlock it remotely using Samsung Find My Mobile even without a Google account.

Steps:

1. Go to https://findmymobile.samsung.com
2. Sign in with your Samsung account
3. Select your device
4. Click Unlock

This removes the lock screen without deleting your data.

Works only if:

• The Samsung account was added before the lock
• Device is online
• Remote unlock is enabled

Fix 7: Boot into Safe Mode

This is because of an external screen lock app, which can be removed by using the safe mode option. In safe mode, only apps pre-installed with the OS can run.

First, press your device’s power key until you see the reboot options. Then click on Power off for a few seconds until Safe Mode appears. Next, from safe mode, go to settings and uninstall the problematic app.

Fix 8: Factory Reset Android Phone (Remove Lock Screen)

A factory reset will help you remove the password by wiping all the data from your phone.

 Before You Reset

• This will delete all data (apps, photos, files)
• After reset, you must sign in with your previous Google account (FRP lock)

What is FRP and How to Bypass It After Factory Reset

Factory Reset Protection is a security measure built into Android smartphones to prevent unauthorized use of the device after a reset. When you reset your phone, the phone will prompt you to log in to your previous Google account for authentication.

Step 1: Sign in with Your Google Account

Log in to your phone with your previous Google email address and password.

Step 2: Forgot Your Google Account?

If you don’t have any memory of your Google account login details, you can visit the account recovery page from another device.

Step 3: FRP on LG Devices

FRP on LG handsets is much more complicated due to their Secure Startup and encryption capabilities. LG phones will still need to authenticate with the original Google account, even if they are sold after a factory reset.

Step 4: Last Option

If none of the previous options work, bring your phone to an authorized service center and show them the purchase receipt. They will be able to unlock the phone using the information provided.

Important: There is no officially approved or secure way to bypass FRP.

Fix 9: Use Professional Unlocking Tools

As a last resort, you can use third-party tools to remove the lock screen. Note that this method may erase your data on some devices.

Steps to use third-party tools:

1. Download and install them on your computer, then open them.
2. Click on “Screen Unlock” from the main dashboard.
3. Connect your locked Android phone to the computer using a USB cable.
4. Select “Unlock Android Screen” from the available options.
5. Choose your device brand, name, and model correctly.
6. Follow the on-screen instructions to enter Download Mode (usually by pressing the volume and power buttons).
7. Once detected, they will automatically download the required firmware.
8. After the process completes, I will remove the lock screen.
9. Your phone will restart, and you can set it up again.

Advanced Technique: ADB (RARE USE CASE)

This approach involves using ADB to delete the lock screen files from your Android device. It is worth noting that this solution only works if you previously enabled USB debugging. Unfortunately, for most users, this option would be impossible to implement because it is rarely used.

How it works:

• USB debugging was already enabled
• The device was previously authorized on the same PC
• The device is not fully restricted by encryption

Fix 10: Go to an Authorized Service Center

If you are uncomfortable with technical solutions or if your phone contains sensitive information, going to an authorized service center is your best option.

Your phone will be unlocked by technicians using legitimate methods at the authorized service center. While it takes time and incurs costs, it is less risky than other solutions.

5. Is “Enter Password to Unlock 30/30 Attempts Remaining” a Problem with Other Android Phones Too?

Yes, the problem is not exclusive to LG Android phones. It can also be displayed on a Samsung, Xiaomi, Vivo, Oppo, or any other Android smartphone.

5.1 On Samsung Devices

On Samsung phones, the problem is often associated with Secure Startup and device encryption. After the phone is rebooted, Samsung requires the correct password to unlock using fingerprint or face unlock.

• Repeated incorrect attempts will lead to delays or even blocking access.
• On Samsung One UI, the wording might differ, but the concept is the same.

This is particularly prevalent on devices running older versions of Android or on devices where encryption is strictly enforced.

5.2 On Xiaomi Devices

On Xiaomi devices (MIUI), the error is usually tied to Mi Account security and system encryption.

• The device may require the password after reboot for verification
• If linked to a Mi Account, it may require additional authentication
• In some cases, incorrect attempts can trigger temporary lockouts or syncing issues

Xiaomi devices may also show account verification prompts instead of a simple password retry screen.

5.3 On Oppo and Vivo Devices

On Oppo and Vivo phones, this issue is typically related to system-level security and lock screen protection.

• After a restart, the device requires the main password instead of biometrics.
• Repeated incorrect attempts can lead to temporary input restrictions
• Some models may enforce stricter delays between attempts

While less aggressive than LG’s Secure Startup behavior, the lockout mechanism still prevents unauthorized access.

6. How to Prevent “Enter Password to Unlock 30/30 Attempts Remaining” Error

6.1 Pick a Strong but Memorable Password

Make sure your password is strong enough to protect your data while remaining memorable. Do not try any passwords that will definitely not work; instead, use the recovery service.

6.2 Set Up Date & Time Right

Incorrect date and time settings can sometimes cause issues with the device’s authentication process. Ensure that date and time settings are done automatically through the device’s settings menu.

6.3 Ensure Regular Updates

Updates solve the bugs that may arise during authentication when you log in to your device.

6.4 Disable Secure Startup

To turn off this option, go to:
