NixOS 25.11 for Xiaomi Pad 6 (pipa)

An experimental NixOS setup for the Xiaomi Pad 6

Overview

This repo is my personal project to configure and make NixOS usable on the Xiaomi Pad 9.

Key Features

• Relatively small Considering this setup is based on stripped down Gnome including Firefox and some smaller packages, the rootfs comes out to abou 7.6 GB.
• Fully declarative As one would expect from NixOS.

Prerequisites

Before flashing this OS, ensure you have the following:

1. Unlocked Bootloader: Your Xiaomi Pad 6 must have its bootloader unlocked.
2. Android Platform Tools: fastboot installed on your host machine.

Installation

WARNING: This process will overwrite your boot, cust and userdata partitions. All existing Android data will be destroyed. Back up your files before proceeding.

1. Reboot your tablet into Fastboot mode (Hold Power + Volume Down).

2. Connect the tablet to your PC via USB.

3. Flash the Mu Silicium, boot and root filesystem images:

   # Single boot instructions:
   
   # Flash Mu Silicium
   fastboot flash boot_ab silicium.img
   
   # Flash the UEFI boot partition
   fastboot flash cust boot.img
   
   # Flash the Btrfs root filesystem image
   fastboot flash userdata rootfs.sparse.img
   
   # IMPORTANT! Do not forget to erase dtbo_b! Otherwise your device will not boot:
   fastboot erase dtbo_ab
   
   # ALSO VERY IMPORTANT! DO NOT reboot via the power button. Let the tablet completely write the images to UFS:
   fastboot reboot
   

Reference: Fedora Pocketblue installation instructions.

For dual booting

You will need to split up userdata into 3 partitions:

• userdata (for Android)
• boot (1GB)
• rootfs

Default credentials:

• Username: nixos
• Password: nixos
