In this guide, we will show you the steps to flash the TWRP Recovery in the vendor boot partition. If you are stepping into custom development, then a custom recovery will prove to be the most powerful tool that you could have in your arsenal. From flashing custom ROMs to taking Nadroid Backups, these recoveries behold a slew of useful functionalities up their sleeves. However, flashing them has proven to be quite a challenging task in recent years.
The reason for the same is the different partition styles that each device beholds. For instance, while some have a dedicated recovery partition, it’s missing from others. So while you could flash a custom recovery directly to the recovery partition in the former, you’ll have to take the help of the boot partition and then the ramdisk to get the job done in the latter. Then, there’s this third method of flashing TWRP Recovery- which involves the vendor partition. Here’s everything you need to know in this regard.

What is Vendor Boot as Recovery [A/B Partition]
These devices don’t have a dedicated recovery partition. And even though it does have a boot partition, but the ramdisk doesn’t reside there, instead it is present in the vendor_boot partition [hence you cannot flash it via the Install Recovery Ramdisk method]. Moreover, you cannot even use the fastboot boot recovery.img command to temporarily ‘boot’ your device to the recovery. All in all, flashing the recovery to the vendor_boot partition is the only way out.
