We recently talked with you about the bootloader on Android and its importance on Android. The first step if we want to get into the world of roots, to know if this is on or not. The most common is that Android phones come automatically locked, forcing us to unlock them.
Although important Know first when the phone bootloader is actually locked or Not To know this there are many options, which allow users to check and know its status in several steps. We tell you the different ways we can use it below.
What is your Android bootloader and why is it so important
We explain what your portable bootloader for Android is, what security functions it performs and everything to look for in reference.
How to you know the phone booth is locked or not using recovery mode on Android, the most important task. It's a way we can access all Android phones, even though our access to this mode may vary depending on the type of phone. But it's one of the most reliable ways to know this device.
How we can get in It depends on the type of product. The most common is to turn the phone off completely and then turn it on while pressing the volume key down at the same time (mounting other products). If you do, you have access to the phone recovery mode. In this mode you should get details about the bootloader.
Here you will be able to see whether or not she is on the phone. As we have already mentioned, it will automatically be locked. There are a few products on Android that open it up, it's small and small, so we can expect some effect in this case.
The secret codes
In Android we find many codes called confidential, giving us access to certain functions or information on the phone itself. They are very useful in these types of situations and we can reach out to most brand on Android Though it is something that loses its existence and over time. Therefore, in most current phones we cannot use certain codes, because they do not work.
To find out when the boot booter device is locked, there is a code. This code is # # # 7378423 # * # * that we should get inside the phone app for. Because of it you have access to a new window, where we have in formation by phone. You must enter a section called Service info and edit. Inside it, it will be notified whether this bootloader is blocked or not.
Introduced as a very useful way for users on Android. It's easy to use and very fast. But it has a problem, from this perspective does not apply to most current models. In most cases when putting this code into a device doesn't happen, so it's not something that will work for other users, which is annoying.
Huawei would not agree to open the bootloader on the Mate 30
A few days ago, Huawei's CEO confirmed that the product type would allow the Mate 30 bootloader to unlock, a decision they didn't take long to fix.
In addition, it is unknown if there are certain products or models where it does not work. I have tried it on several models (Huawei P30 Lite, P Smart + 2019 and Galaxy A50) and none of them happened to use that code. But if you have an Android phone for at least a few years, then this tactic might work for you. It's worth a try, because it's something that works quickly and simply over the phone.
From the PC
One way to know whether the bootloader is locked or not is to use a computer. To get this we have to use ADB and Fastboot
First you need to have the phone in Fastboot mode, what can we do with ADB. We will only need to execute the command called adb reboot fastboot on it and enter that mode. Once this is done, you should use the instructions for the hardboot devices, to make sure the system recognizes the phone. This command is responsible for opening or at least trying, the phone bootloader.
It is normal to say that it is right, which means that it is no longer blocked or in error. If an error occurs, it means that it means the bootloader is still closed There are several additional commands that can be tested, but none of them change anything. Also, they rely on the phone type, because it doesn't work at all. But with the previous command we often know if it's blocked.
