There’s a plethora of tweaks, modifications, and custom binaries available for various LG devices, and the LG Velvet is no different either. Although it has only been only a couple of months since its launch, we are already seeing impressive support for this device. But to carry out these tweaks, there is just one requirement that needs to be met- your LG Velvet should have an unlocked bootloader. In this guide, we will help you with just that.

Advantages/Risks with an Unlocked Bootloader

There is a plentitude of perks associated with an unlocked bootloader. To begin with, you could flash custom ROMs like LineageOS, Pixel Experience, etc. Along the same lines, installing a custom recovery like TWRP is also a possibility. This in turn will allow you to flash ZIP and IMG files, wipe various partitions, create and restore Nandroid backup, etc. Likewise, you could also root your device via Magisk and gain access to administrative rights.

However, these modifications come with a few risks as well. For example, it will wipe off all the data from your device and might make the warranty null and void as well. Furthermore, apps like Google Pay, Netflix, and Pokemon Go might not function properly. The entire process is risky and might cause a few issues if not performed correctly. With that said, if you are ready to proceed ahead, then here are the steps to unlock the bootloader on the LG Velvet.
