How to Install a Custom ROM

Complete guide to flash any AOSP custom ROM on Poco X6 Pro 5G (Duchamp). Requires unlocked bootloader. ⏱ ~20 minutes.

⚠ Before You Start

Bootloader must be unlocked — See Unlock Guide →
Full backup of all data — this process wipes your device
Phone charged to at least 60%
ADB + Fastboot installed on your PC
Download: ROM zip, boot.img, vendor_boot.img from the ROM page

1️⃣ Download Required Files

From the ROM page, download:

ROM.zip — the main ROM package
boot.img — custom kernel/boot image
vendor_boot.img — vendor boot image

Transfer all files to your PC (not the phone) before starting.

2️⃣ Flash Boot & Vendor Boot

Power off your phone, hold Volume Down + Power to enter Fastboot, then connect to PC via USB-C.

# Verify device is detected fastboot devices # Flash boot images fastboot flash boot_ab boot.img fastboot flash vendor_boot_ab vendor_boot.img

3️⃣ Boot into Recovery

fastboot reboot recovery

Your phone will reboot into the custom recovery screen.

4️⃣ Wipe Data

In recovery, select Wipe data / Factory reset and confirm. This is mandatory for a clean flash — it deletes all user data.

5️⃣ Sideload the ROM

In recovery, select Apply update → Apply via ADB, then on your PC run:

adb sideload ROM.zip # Wait for the process to complete (may show 47% — this is normal)

6️⃣ Reboot to System

After sideloading completes, select Reboot system now in recovery. First boot takes 3–5 minutes — this is normal. Do not panic!

✅ Done!
