Now that you are fully acquainted with the device’s specs, here are the steps to unlock the bootloader of Vivo Z1 Pro.

What is Bootloader?

According to Google “A bootloader is a vendor-proprietary image responsible for bringing up the kernel on a device. It guards the device state and is responsible for initializing the Trusted Execution Environment (TEE) and binding its root of trust”. Confused? So am I! let us leave all this aside. In simpler terms, a Bootloader is a software that runs every time your phone boots (start). It contains a set of instructions that tells the device which program to load at what instance. It also decides whether to boot your device to ‘Android OS’ or the ‘recovery mode’.

By default, most of the OEMs ships their devices with a locked bootloader. The reason for their part is quite simple: they only want you to run the OS that they ship on their device. The reason for the same is due to security concerns. But they still leave a window of opportunity for the tech geeks those who wish to tweak their device’s system. And if you are one of them, then this guide is all that you will require.

Why Should I Unlock the Bootloader of Vivo Z1 Pro

Unlocking your device’s bootloader is like opening the gate to a plethora of opportunities. You could flash various Custom ROMs, install Custom Recovery (like TWRP), try out tons of mods and hacks, and most importantly- root your device. After you get administrative privileges, you could then try out a ton of Magisk ModulesXposed Framework among others.

What is even more interesting is the fact that just by using a single line of code, the bootloader could be unlocked. So what are you waiting for, go ahead and give it a try, or should you? Before beginning with the process of unlocking the bootloader of Vivo Z1 Pro, make sure to read the downsides of unlocking it. All this is mentioned in the below article.

Downsides of Unlocking the Bootloader

The biggest downside of unlocking the bootloader is that the warranty of your device would be void. But why do the manufacturers do this? The answer is simple. All the OEMs ship their devices with a locked bootloader so that the users could only use the stock OS that comes pre-installed.

The device vendors do not want the users to try out the customized version of the OS as they are launched by third-party sources such as LineageOS or Resurrection Remix. The manufacturers are in no way related to these creators, hence they distance themselves by voiding the warranty of the device.

Apart from the warranty void, you will also lose all the data stored on your device. Moreover, some apps like Netflix also has some negative consequences. The L1 Widevine Certificate gets lowered to L3 and as a result, you wouldn’t be able to stream Netflix contents in HD quality. Last but not the least, there’s always some chances of your devices getting bootloop or ending in a bricked state.

So, Should I Unlock My Device’s Bootloader

See, the onus completely lies in your hands. If you are among the tech geeks who love to tweaks with their devices, then give no further thoughts. As far as the warranty is concerned, well trust me there is ‘no’ software issue which cannot be rectified by yourself if you have some knowledge about rooting and flashing related stuff.

So the need to meet the guys at the service center does not arise! In a nutshell, if custom ROMs and rootings are what you think of day and night, then look no further. But if you only use your device only for chatting and calling purposes, then I’m there isn’t much in store for you. You could very well carry on with the normal uses, without ever giving a second thought of unlocking the bootloader.

How to Unlock the Bootloader of Vivo Z1 Pro

    1. Hi Himanshu, here are a few things that I need to know:
      1. Please Double check that OEM Unlocking Options under Developer Options is still enabled. Sometimes after a reboot, it automatically turns off (yaa I know it’s weird, but it does end up happening sometimes).
      2. Make sure you are NOT using Minimal ADB or any other such tool. Only use the official Android SDK and Platform Tools.
      3. When you boot your device to fastboot and connect it to PC, enter fastboot devices command. Does it show a randomly generated strings of alphanumeric command?
      4. Finally, someone has suggested me to try out the following command: fastboot bbk vivo_bsp unlock_vivo . But I haven’t been able to try out this code. If you are ready to try it out, please try this command (maybe risky!) and do let me know if your error gets rectifed or not.

    1. Hi Aakash, it seems that the ADB Drivers are conflicting. Make sure to remove all the other third-party ADB drivers and download only the one provided by Google. You could download it from this guideList of Useful ADB and Fastboot Commands | Download Platform Tools. Where these drivers are installed you would get the platform-tools folder. Launch the Command Prompt window inside that folder (by entering CMD in its address and hit Enter) and then try unlocking your device. Let me know if it helped you or not.
