Firstly, you need to unlock bootloader (See section below).

Enter fastboot mode (hold vol- and pwr buttons while turned off), and run this commands:

1. Disable VerifiedBoot

```bash
fastboot flash vbmeta prebuilt/vbmeta_disabled.img
fastboot flash vbmeta_system prebuilt/vbmeta_disabled.img
fastboot flash vbmeta_vendor prebuilt/vbmeta_disabled.img
```

2. Flash dtbo and boot

```bash
pmbootstrap flasher flash_kernel
pmbootstrap flasher flash_dtbo
```

3. Flash system

```bash
fastboot reboot fastboot
fastboot delete-logical-partition product
pmbootstrap flasher flash_rootfs
```
