All Answers about What is OEM Unlock

Do you want to enhance your Android device's functionality? Yes, you can do it by unlocking the bootloader, installing a custom recovery, installing a custom ROM, and, of course, rooting and personalizing your Android device. Therefore, if you wish to do either of the above, you must proceed by authorizing OEM unlocking on your Android device. Here's a comprehensive explanation of what is OEM unlock, why you may really need it, and how you can do it in minutes on Android phone.

Part 1: What is OEM Unlock

OEM unlock is a function that was included in the Android OS' Developer Options menu. The function has been introduced to Settings that must be enabled before users may decide to open their Android device's bootloader. If enabled, the bootloader of your Android device enables rooting, whether it was limited to a single network provider when bought.

Besides, the OEM unlock has the basic purpose of enabling the command "fastboot flashing unlock" to run. The option is hidden from display, as neither Google nor the Android OEM brand that manufactures your smartphone wants you to tweak with the device beyond what it was designed to do.

So, this is actually what does OEM unlock means.

FAQs about OEM Unlock

1. Distinction Between Bootloader and OEM Unlock

The Bootloader is a storage-based operating system that must be loaded into memory prior to usage. When your device boots, its memory does not have a program that allows it to access components such as I/O devices or storage.

On the other hand, the Fastboot OEM unlocking procedure involves activating a special switch that enables you to unlock the bootloader via fastboot commands. Bootloader and OEM unlocking are intrinsically tied, as the OEM unlock is required to unlock the device's bootloader.

2. Is OEM Unlock safe?

Android geeks sometimes unlock their devices' bootloaders in order to root them and mount custom ROMs. However, devices come with disabled bootloaders for a reason – opening the bootloader poses security risks. For the same cause that Android is not pre-rooted, it is not pre-unlocked – with additional strength comes additional risk.

3. Why OEM Unlock Missing?

On many smartphones running Android 5.0 Lollipop or higher, the Developer Options menu can include an option named “OEM unlocking”. Typically, this error occurs as the device enters the Prenormal RMM state.

4. Why OEM Unlock Greyed out?

OEM unlock becomes inaccessible for one of three reasons: Android OEM unlock is not accessible, your smartphone is already boot loaded, or you recently activated the bootloader.

Certain Android OEMs would consider the guarantee null and void if you open the bootloader. Additionally, it's reasonable to assume that they're not really comfortable with you doing it.

Moreover, anytime you need to open or relock your mobile device's bootloader, this error appears. However, the Developer Options' OEM Unlock feature can be greyed out or unchecked.
