## How to flash ## How to prepare a phone
Firstly, you need to unlock bootloader [(See section below)](https://github.com/MeexReay/pmos-xiaomi-angelican?tab=readme-ov-file#how-to-unlock-bootloader). \ ### Unlock bootloader
If you have already manipulated partitions, it is recommended to [flash MIUI back](https://github.com/MeexReay/pmos-xiaomi-angelican?tab=readme-ov-file#how-to-flash-stock-firmware), and flash PMOS above it.
### Flash with prebuilt images Here is described the unofficial method with mtkclient
Enter fastboot mode (hold vol- and pwr buttons while turned off), and run this command: #### Drivers
```bash - **For Windows:**
cd prebuild && ./flash.sh
```
Password: 1234
UI: surprise
### Flash manually
1. Build images
```bash
pmbootstrap init
pmbootstrap install
```
2. Disable VerifiedBoot and flash boot partition
Enter fastboot mode (hold vol- and pwr buttons while turned off), and run this commands:
```bash
fastboot flash vbmeta prebuilt/vbmeta_disabled.img
fastboot flash vbmeta_system prebuilt/vbmeta_disabled.img
fastboot flash vbmeta_vendor prebuilt/vbmeta_disabled.img
pmbootstrap flasher flash_dtbo
pmbootstrap flasher flash_kernel
```
3. Flash system
```bash
fastboot reboot fastboot # enter fastbootd mode
pmbootstrap flasher flash_rootfs # flash system
```
4. Reboot
```bash
fastboot reboot
```
## How to flash stock firmware
