How To Fix OEM Unlock Missing on Xiaomi Redmi Note 12 Pro 4G?

Original Equipment Manufacturer (OEM) Unlock is a function on Android devices. It allows you to unlock your phone bootloader. A bootloader or bootstrap loader gathers the operating system files, loads them into memory, and hands over control, essentially starting your device. Unlocking the bootloader assists you in installing custom ROMs, flashing custom kernels, and rooting your phone.

However, this freedom comes with some trade-offs. Most manufacturers will void your warranty if you unlock the bootloader, and it can also make your phone face higher risks of malware and other security threats. Additionally, it can be difficult to relock the bootloader once you unlock it.

If you encounter the OEM unlock missing on your Android phone despite wanting to unlock your bootloader, this article can help. You will learn the step-by-step guide for the different methods to fix the missing OEM unlock option. Before diving into solutions, let’s explore why this option might be unavailable in the first place.

Part 1: Why Is OEM Unlock Missing on Your Device?

Finding that OEM Unlock is missing on your Android phones can be frustrating, particularly if you plan to modify your software or install a custom ROM. But don’t worry. There are several possible explanations for this. Let’s explore some of the most common reasons:

Manufacturer Restrictions

The Missing OEM Unlock option can often be due to restrictions imposed by your device’s manufacturers. They may intentionally remove this option to safeguard device security and compatibility. It is common with carrier-locked devices. As a result, the OEM Unlock option may not show.

Bootloader Already Unlocked

In some cases, the Android OEM Unlock Missing issue arises when the bootloader has already been unlocked. Relocking the bootloader might make the option reappear. But exercise caution as this process can erase device data.

Developer Options Not Enabled

It might seem obvious, but sometimes the simplest things get overlooked. The OEM Unlock option can only be accessed from within Developer Options. If this menu isn’t enabled, you won’t see it.

Carrier-Locked Devices

The OEM Unlock Missing issue can also occur if your device is carrier-locked. Carriers often impose restrictions to prevent users from switching networks, and bootloader unlocking is one way to do that. Unfortunately, the missing OEM Unlock option is usually intentional, and unlocking your device can be more complicated.

Security Features

Enhanced security features, like Samsung’s KNOX, can sometimes conceal the OEM Unlock option. Temporarily turning off these features might show the option, but it’s crucial to be aware of the potential security implications of doing so.

Corrupted Bootloader

A corrupted bootloader can also lead to the Android OEM Unlock missing problem. The bootloader plays a role in the boot process, and if it’s damaged, it might not display the necessary options. This can be caused by software glitches, failed flashing attempts, or even hardware issues. In this scenario, you might need to consult your device’s manufacturer or a technical specialist to help repair or re-flash the bootloader.

Connectivity Issues

A poor connection between your device and computer can also prevent the OEM Unlocking from showing up. Check your cables and try using different USB ports to ensure a stable connection.

Part 2: How To Enable Missing OEM Unlock Without a Password?

Unlocking your phone’s bootloader (OEM Unlock) varies across models and brands. Some need a passcode or PIN after rebooting the phone, while others don’t. Even if your phone doesn’t require a separate password, your existing screen lock (password, PIN, pattern) will usually be needed to enable the missing OEM unlock option.

But what if you forgot that, too? Wondershare Dr.Fone - Screen Unlock can help bypass forgotten passwords and unlock your phone even if you don’t have the technical knowledge. Here’s a quick breakdown of its key features in this area:

Now that you’ve regained access to your device thanks to Dr.Fone - Screen Unlock, you can move forward with enabling the OEM unlock missing option. Next up, we’ll guide you through the steps in several ways. Let’s start with the Developer options.

Part 3: How To Enable OEM Unlock Missing From the Developer Options?

Developer Options, a hidden menu in Android, offers advanced features like app debugging and custom ROM installation. But if the Android OEM unlock option is missing, you can’t unlock your device’s bootloader. Below is a step-by-step guide for you so the OEM unlock missing option will show in the Developer Options. Remember, this process may erase your device data, so a complete backup is essential before proceeding.

  • Step 1: Open the Settings app on your Android phone.
  • Step 2: Navigate to About Phone at the bottom of the list, then tap Software information.

  • Step 3: Tap on the Build number repeatedly (7 times) until you see a message saying, “You are now a developer!“ or similar.
  • Step 4: Go back to Settings > System and find the Developer options menu.
  • Step 5: Scroll down and tap the toggle switch next to Enable OEM Unlock to turn it on.

  • Step 6: A warning message explaining the risks of turning on the OEM unlock will appear. Read it carefully and tap Enable if you want to proceed.

turn on oem unlock

  • Step 7: Enter your PIN or password to confirm the unlock when prompted
  • Step 8: Your device will reboot, and OEM Unlocking will be enabled.

Part 4: How To Fix OEM Unlock Missing by Adjusting Date and Time?

Some manufacturers intentionally delay the availability of the OEM unlock after a software update for security reasons. Changing the date to a past date before the update rolled out can trick the system into displaying the option, as it thinks the update hasn’t happened yet. It is a temporary fix, and the option will likely disappear again later when the Xiaomi Redmi Note 12 Pro 4G device automatically syncs the correct date.

If you intend to try this method, follow these steps to enable OEM unlock missing or greyed out after an Android update:

  • Step 1: Open the Settings app.
  • Step 2: Go to System or General management, depending on your Android version.
  • Step 3: Tap on Date and Time.
  • Step 4: Turn off Automatic date and time.

turn off automatic date and time

  • Step 5: Tap on Set date and choose the desired older date from the calendar.
  • Step 6: Tap on Set time and choose the desired time from the clock.
  • Step 7: Tap on Done to save the changes.
  • Step 8: Go back to the Developers options and turn off the Auto update system option.

turn off auto update system

  • Step 9: Go to Settings > Software update, then turn off Auto download over Wi-Fi.

This method should enable the OEM unlock missing issue. Otherwise, proceed to the next section for another solution.

Part 5: How To Fix OEM Unlock Missing by Removing SIM Card?

Certain carriers restrict bootloader unlocking on their devices to ensure compatibility and prevent unauthorized modifications. For these phones, unlocking the SIM card becomes crucial before you can toggle the OEM unlock option. Here are the steps to fix the OEM Unlock missing or greyed out using SIM card removal:

  • Step 1: Use the SIM ejector tool (often included with your phone) or a small pin to push the tray out.
  • Step 2: Go to Settings > General Management > Reset, then select Factory data reset. Enter your PIN or password if needed.

  • Step 3: Review the warning and tap Reset to confirm.
  • Step 4: Once the reset is complete, your phone will restart. Connect to Wi-Fi when prompted.
  • Step 5: Skip any prompts to log in to your Google or email account. Then, repeat the process to open the Developer Options in the previous sections.

Conclusion

Having the OEM Unlock missing or greyed out can leave Android users feeling locked out of customization possibilities. Fortunately, this article has outlined helpful solutions like enabling the Android OEM Unlock missing option via the Developer Options. You can also try other methods above, like adjusting date and time settings or even a sim card removal trick. For those facing forgotten lock screens, we’ve offered guidance on bypassing them using the Dr.Fone - Screen Unlock tool to access the necessary phone settings.

While these methods provide a solid foundation, it’s always wise to research steps specific to your phone model. And never forget – caution is key. If things get technical, don’t hesitate to seek help from online communities or professional repair services.

Pattern Locks Are Unsafe: Secure Your Xiaomi Redmi Note 12 Pro 4G Phone Now with These Tips

Pattern locks have been available for about as long as people can remember, and they have been hugely popular with people thanks to how easy it is to simply swipe your screen and unlock your smartphone, as against, say, keying in the 4-digit PIN/ 6-digit PIN. However, pattern locks are easy to crack, and today, we bring you all you want to know about pattern locks and how to create a hard pattern lock. Further to this, we also tell you how to move beyond pattern locks and what to do in case you forgot the hard pattern lock you just set and are unable to unlock your smartphone.

creating more secure pattern locks

Part 1: What You Need to Know About Pattern Locks

Pattern lock is an Android-only feature that makes it easy for users to have a modicum of security on their smartphones. Most users do not prefer using and remembering a PIN to unlock the smartphone. Creating a pattern makes it easier, somehow.

There is a 9-point grid on which you swipe your finger from point to point, in any direction, and when you take your finger off, that pattern you swiped becomes the key to unlock your smartphone.

Pattern locks were exceedingly common only a few years ago, and they are not recommended for use any longer due to concerns (mentioned later in the article).

BLUETTI NEW LAUNCH AC180T

1.1: Popularity and Usage

Old habits die hard, or so they say, right? That’s because it is true. We are creatures of habit, and pattern locks have been around for a long, long time. We are accustomed to pattern locks. So, even with even easier technologies such as fingerprint recognition and face recognition, we tend to gravitate towards the familiar old pattern lock.

The only thing is, there is a reason why pattern locks are no longer the preferred option to use for unlocking your smartphones. As it happens, that reason is security, and it can be very easy for humans to take a swipe (pardon the pun) at your pattern lock. And guess what? The research conducted suggests that they would get it right with an unsettling accuracy.

1.2: Advantages and Drawbacks

With on-the-go lifestyles, our smartphones have become indispensable and contain some of the most sensitive aspects of our lives – IDs, credit and debit cards in digital wallets, photo and video memories, business documents – you name it, the smartphones have it, on the go. This has opened our lives up to the public at large, and if someone steals our smartphone or, best case, finds it, the only barrier preventing them from being privy to all that wealth of our sensitive information is that screen lock – the pattern lock that we set on our smartphones. That’s it – the single pattern lock stands between malicious actors and our data. You might be beginning to realize just how crazy this is.

Advantages of Pattern Locks

There are two advantages to using pattern locks. One, they are better than nothing. Two, they are easy to use. And that’s about it. There is no third advantage to pattern locks. We might think we set a hard pattern lock that nobody could guess, but, as research proves, we might be thinking too low of human prowess.

Disadvantages of Pattern Locks

Security, or rather, the lack of it, is the lone disadvantage of using a pattern lock. What good is a pattern lock that can be easily deciphered? Sure, they are easy to use, and they are better than not having anything, but would you really want to protect your life’s data with something that could be, as researchers found out, breached in under 5 attempts? We don’t think you do!

The research found that 64% of test subjects who were shown videos of people unlocking their phones could correctly guess a 6-point pattern lock, that too after viewing the video only once! That number shot up to 80% if they were allowed to see the video again. That is simply astounding and a nightmare for security. When it comes to PINs, only 11% could guess a 6-digit PIN after viewing the unlocking video once, and that number shot up to 27% when they could see the video two times.

Part 2: How To Create a Hard Pattern Lock (Including Remembering Complex Patterns)

Now, if you must continue using a pattern lock, let’s help you know how to create a hard pattern lock that would not be as easy to decipher as easy pattern locks. For that, you should know how people use pattern locks, the kind of pattern locks they create, and the ones that are the most commonly used pattern locks. That way, you can avoid those fallacies and create a hard pattern lock for your smartphone.

2.1: The Pattern Locks People Use Most Commonly

![common pattern locks](https://images.wondershare.com/drfone/article/2023/09/hard-pattern-lock-2.jpg)

Marte Loge, an M.Sc. Computer Science student, gave a presentation on pattern locks at DEFCON 23 and made a bold claim. She said, “Tell me who you are, and I will tell you your lock pattern.”

She presented the following statistics to support her claim:

  • - In her research, she found that 77% of people started with one of the 4 corners when creating a pattern lock.
  • - 44% of people started with the top-left dot and 15% with the top-right, while the bottom-left was preferred by 14% of her test subjects.
  • - People set 5-point pattern locks on average, and most users were content with a 4-point pattern.

These are some of the most common pattern locks people create:

  • - patterns in the shapes of alphabets,
  • - patterns in the shapes of numerals,
  • - patterns in any other simple shape, such as square, triangle, star, etc.

To understand how this is a security nightmare, the possible combinations for a 4-point pattern are a measly 1624, whereas by adding just 1 more point to the pattern and creating a 5-point pattern, the number of possible combinations becomes 7152, an increase of 5528 combinations. In stark contrast, creating a 9-point pattern would give you over 140,000 possible combinations!

2.2: How to Create a Hard Pattern Lock

Knowing what most people do when creating a pattern lock, it becomes easy to avoid those mistakes and instead create a hard pattern lock for oneself.

  • - Do not start creating a pattern lock from any of the 4 corners of the grid.
  • - Never use your first initial as your pattern lock.
  • - Never use the shape of a numeral as your pattern lock.
  • - Use all 9 points on the grid to create your pattern lock, and contrary to popular belief, you can go over the connecting lines several times, creating a hard pattern lock that would not be as easy for people to decipher!

Part 3: Going Beyond Pattern Locks

You might think that now that you have set a hard pattern lock, you are good to go. Hardly. Technology has evolved, so have methods to break into your device.

Step 1: Set a 6-digit PIN

The minimum you should do today is set a 6-digit PIN to unlock your phone. Consider this a necessary investment into the safety of your data residing on your smartphone.

Step 2: Use Fingerprint Recognition (or Face Recognition on Apple Devices)

All modern smartphones released over the last decade have come with fingerprint recognition. Using fingerprint recognition requires you to set a 6-digit PIN and then set a fingerprint to unlock your device. You can set additional fingerprints, too.

This way, your device is the most secure it can be today. In case your fingerprint is not recognized for any reason, the phone falls back on the 6-digit PIN that you can enter and unlock your phone.

While face recognition is available on both Android and Apple devices, it is truly secure only on Apple devices. This is why Apple iPhones released after the iPhone X in 2017 have come only with Face ID. They fall back on a minimum 6-digit PIN (called Passcode in Apple world) to unlock in case the face does not get recognized in the first attempt.

Part 4: How To Unlock Phone If Hard Pattern Lock Forgotten

Just in case you set a hard pattern lock and promptly forgot that abstruse pattern you just set, we have a tool for you to quickly unlock your phone in case of a forgotten hard pattern lock: Wondershare Dr.Fone - Screen Unlock.

Closing Words

Whether it is an easy pattern lock or a hard pattern lock, the fact is that pattern locks are antiquated and a security nightmare. A minimum 6-digit PIN must be used, and using fingerprint recognition is the preferred way to go for Android devices. Using fingerprint recognition will require that users create a 6-digit PIN.

Are you stuck with a locked phone? And you’re still confused about what just happened. Face unlock may face problems such as

  • Face unlock app may be buggy
  • Your face unlock settings may be unstable

Whatever the reason, they are equally big obstacles for you to use your phone as usual; trying to unlock your device can lead to a permanently locked phone. So how do you bypass face unlock?

Follow the guide below to bypass the face unlock settings and choose the best one for yourself.

How To Bypass Android Face Lock by Ourselves?

If you want to bypass face lock by yourself, then different methods can help you. These are all tested and work well.

1. A Picture Possibly Bypasses Face Lock

You can use your photo to manipulate the face lock app. Simply use your photo to unlock the phone, which should work fine. If your phone doesn’t recognize your face from a photo, try again.

If it still doesn’t recognize your face, try a different photo or even change the camera’s lighting settings or the angles to see if that helps.

Anyway, this method is still unstable because of many uncontrollable factors. If everything fails, consider the following methods to bypass the face lock.

2. Hard Reset your phone

To get around the Android lock screen, perform a factory reset. While resetting your phone allows you to set a new password, it also erases all data from your device. This method works like a charm, but it also requires more technical knowledge. To bypass screen lock via factory reset, follow these steps.

android hard reset

Step 1: Turn off your phone and hold the Power and Volume-down buttons simultaneously until the recovery mode screen appears. There are minor variations depending on the brand and model.

Step 2: Select the Wipe data/Factory Reset option using the volume buttons. To confirm the option, press the Power button.

Step 3: Choose Yes > Delete All User Data, then press the power button to continue. When the process is complete, turn on your phone.

So, before facing such awkward cases, like data loss, we suggest you have a backup habit of keeping your data safe.

3. Google Find My Device

Google Find My Device is a service that lets you remotely lock, track, and wipe data from stolen or lost phones. With a Google account and the password, it won’t be complicated to remove any locks on your phone. You can bypass the Android lock screen by following the steps below:

google find my device data reset

Step 1: Navigate to Find My Device and sign in with your Google account.

Step 2: Your phone receives a notification.

Step 3: Select Erase Device, confirm, and click Erase as a warning pops up on the screen.

Step 4: The factory reset process on your phone begins. When it’s finished, choose My Google Account instead of using your phone as if it were brand new.

Just like the hard reset, after using Google Find My Device, all your data and settings will be erased. Please make everything well prepared before you decide to unlock your device.
