Method #1: Flashing a Boot Image using Fastboot The same instructions will apply while flashing both, a stock boot or a patched boot image. We have covered both the methods below for you. The latter is more convenient because it wouldn’t require a computer. The alternative way is to flash the boot image file through TWRP recovery (in case you have that installed). Installing or flashing a boot image file on your OnePlus 8T could be easily done by executing a Fastboot command from your computer. It could help you eliminate the possibility of having a modified boot partition causing a problem. In such a case, the stock boot image could come in really handy for uninstalling Magisk and unrooting the phone completely.įlashing the stock boot image is also considered one of the first steps when debugging and fixing software boot loops. However, there could be a chance that Magisk might not have stored a backup of your stock boot image – (1) because you used a pre-patched boot image provided by another person, or (2) because of a general software error. Generally, Magisk creates a backup of your phone’s stock boot image during the installation process. A copy of the stock boot image file for the installed OxygenOS version is required during the rooting process, as shown in that tutorial.Ī stock boot image also plays a very important role when unrooting the phone.

Recently, we covered a tutorial a step-by-step tutorial on rooting the OnePlus 8T without using TWRP recovery at all. Soon after the launch, the phone quickly picked up a decent amount of support from the custom development community. You can root the phone, install TWRP custom recovery, flash custom ROMs/kernels/mods, and do much more. Meaning, you can play around with the software as much as you like. The software on OnePlus devices is easy to customize due to the fact that the bootloader can be unlocked in a straightforward way. In a similar manner, you might often come around a “Patched boot image”, wherein the word “Patched” generally indicates that the boot image is patched with Magisk. The “stock” moniker is added to represent the unmodified state of a boot image file. It is also the first partition image loaded by the bootloader during a normal boot process.

According to Google, an Android boot image (often referred to as a boot.img) contains the kernel and ramdisk that loads the Android system.
