Benefits of Fastboot ROM

If you are just a normal every day and have no intention of tweaking your device, then you would probably never require a Fastboot ROM. On the other hand, if you are a tech enthusiast, then you would be interacting with this ROM on a regular basis. When OnePlus rolls out the update package, it is in a ZIP format and is the stock firmware that you normally install onto your device. However, if you further extract this ZIP file, then you will get a payload.bin file.

This payload file consists of all the partition files in IMG format. These include the likes boot.img, vbmeta.img, vendor_boot.img, system.img, among others. Now if your device ends up in a bootloop or softbrick state, then you can easily flash these files to their respective partitions, and your device will be up and running. Likewise, if you are planning to root your phone, then you would need to get hold of the boot.img, patch it via Magisk, and then flash it via Fastboot.

Owing to all these reasons, the Fastboot ROM will come in quite handy for your OnePlus 12 under numerous circumstances. So without further ado, grab them right away from the below section!

Download OnePlus 12 Fastboot and Recovery ROM

If you are planning to unbrick your device, then you could download any version of the Fastboot ROM [just it should be of the same region and it’s better if it’s of the same or higher version]. However, if you want the ROM [or rather the init.img] for rooting purposes, then you need to download the same version that is currently installed onto your device [you could verify the same from the Build Number].

NOTE: The ROMs given below are hybrid in nature, meaning they can be used for both Fastboot and Recovery purposes.

5. Now use the below command, replacing location with the sda address: dd if= location of=/sdcard/persist.img bs=4096
6. In our case, the aforementioned command will transform to: dd if= /dev/block/sda8 of=/sdcard/persist.img bs=4096
7. The persist.img will be placed in your device’s Internal Storage. Transfer it to your PC.

How to Restore Persist Partition

So you have messed up the fingerprint on your device? Well, not an issue as you could easily fix it just by flashing the backed-up persist.img file.

So these were the steps to take a backup of the persist partition on your Android device. If you hadn’t taken the persist backup beforehand and your device is currently facing fingerprint issues, then there’s no point in taking the backup of the persist partition and flashing it. This is because the said partition has already been corrupted. Moreover, you cannot use the persist partition image from another user, even if they have the same device and belong to the same region.
