How To Fix OEM Unlock Missing on HTC U23 Pro?

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.

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 HTC U23 Pro device automatically syncs the correct date.

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.
