# PostmarketOS for Xiaomi Angelican (Redmi 9C NFC)
|
|
|
|
This port also might work on angelica (without NFC) and other phones on MT6765 processors (like Redmi 9A).
|
|
If you want to develop it together, or maybe you have a working port, please write me in discord/telegram: [@meexreay](https://meexreay.t.me).
|
|
Also you can find more about me on my site: [meex.lol](https://meex.lol/about)

### Flash stock firmware
|

|
It is recommended to flash stock firmware before doing anything.
|
|
|
|
[Download Firmware](https://xmfirmwareupdater.com/miui/angelican/stable/V12.0.16.0.QCSMIXM/) (MIUI v12.0.16.0) and unpack it
|
|
|
|
- **For Windows:**
|
|
|
|
1. Download [MiFlashTool](https://cdn.alsgp0.fds.api.mi-img.com/micomm/MiFlash2020-3-14-0.rar)
|
|
2. Unpack firmware.tgz to some folder and copy its path
|
|
3. Launch MiFlash.exe and paste the path of firmware folder to that lonely input entry
|
|
4. Click refresh, then flash button
|
|
5. That's all, close the window
|
|
|
|
- **For Linux/MacOS:**
|
|
|
|

|
|

|
### Disable vbmeta
|
|
|
|
```bash
|
|
fastboot flash vbmeta vbmeta_disabled.img
|
|
fastboot flash vbmeta_system vbmeta_disabled.img
|
|
fastboot flash vbmeta_vendor vbmeta_disabled.img
|
|
```
|
|
|
|
## How to flash
|
|
|
|
1. Build images
|
|
|
|
```bash
|
|
pmbootstrap init
|
|
pmbootstrap install
|
|
```
|
|
|
|
2. Flash partitions
|
|
|
|
Enter fastboot mode (hold vol- and pwr buttons while turned off), and run these commands:
|
|
|
|
```bash
|
|
pmbootstrap flasher flash_kernel # flash kernel to boot
|
|
fastboot reboot fastboot # enter fastbootd mode
|
|
pmbootstrap flasher flash_rootfs # flash rootfs to userdata
|
|
# in some cases its good to flash rootfs to system partition too:
|
|
# pmbootstrap flasher flash_rootfs --partition system
|
|
```
|
|
|
|
3. Reboot
