Xiaomi 15, codename dada, is a compact flagship with a 6.36‑inch LTPO OLED 120 Hz display, Snapdragon 8 Elite chipset, up to 16 GB RAM, 1 TB UFS 4.0 storage and a roughly 5.2–5.4 Ah battery with 90 W wired and fast wireless charging.
Early owners praise the Leica camera system and raw performance but frequently report thermal build‑up during social media and video, faster‑than‑expected idle drain and post‑update lag on some HyperOS versions.
The official dada fastboot packages listed below – China OS3.0.5.0 (Android 16 HyperOS 3), EEA OS3.0.6.0 plus multiple HyperOS 2/2.2 Android 15–16 regional builds and a Xiaomi.eu custom ROM – give power users a clean way to unbrick, reinstall or upgrade while applying the latest security patches and stability fixes.

Flashing Requirements
- Xiaomi 15 with codename dada, confirmed in fastboot using fastboot getvar product or via a trusted codename list.
- Bootloader unlocked for all fastboot TGZ and Xiaomi.eu ZIP installs; stock OTA/recovery only on locked devices.
- Windows PC, Xiaomi USB drivers, Mi Flash Tool, reliable USB‑C cable and at least 20 GB free storage.
- Battery charged to 60 % or more because Snapdragon 8 Elite phones can heat up and draw extra power during major updates.
- Full backup of photos, documents and app data; “clean all” fastboot flashing wipes internal storage.
How to Flash the Firmware
Fastboot TGZ ROMs (Mi Flash Tool)
- Download the correct dada_…_images_… TGZ for your region and extract it until you see the images folder and flash_all*.bat scripts.
- Install Xiaomi drivers and Mi Flash Tool on your PC, then select the extracted firmware folder inside Mi Flash.
- Boot Xiaomi 15 into fastboot mode, connect it via USB and click “Refresh” to ensure the tool detects the device.
- Choose “clean all” (recommended for unbrick and major Android 16 upgrades), click “Flash” and wait patiently for a success result.
- Reboot and complete initial setup; slight heating and higher drain for a few days after a big update are considered normal while background optimizations run.
Xiaomi.eu OS3.0.5.0 ZIP (custom ROM)
- Unlock the bootloader, install a compatible custom recovery, then copy xiaomi.eu_DADA_OS3.0.5.0.WOCCNXM_16.zip to internal storage.
- Boot into recovery, back up your current system and wipe data/cache (and system if Xiaomi.eu recommends).
- Flash the Xiaomi.eu ZIP, wait for completion, then reboot into system.
- Expect the first boot to take longer as the ROM configures apps and services; test thermals, battery and notifications after setup.
For step‑by‑step tutorials with screenshots and videos, follow the official guides for Xiaomi Mi Flash Tool, fastboot flash_all.bat scripts and manual OTA / ADB sideload installs.
Frequently Asked Questions (FAQs)
What problems can these Xiaomi 15 ROMs help with?
Full fastboot ROMs can recover Xiaomi 15 units stuck in bootloops, fix failed OTA updates, clear out severe lag from broken mods and apply newer security patches in one clean install.
Does OS3.0.5.0.WOCCNXM fix battery and heating issues?
The changelog mainly mentions a newer security patch and general stability improvements, and community experience suggests that heating often improves slightly after a clean flash plus a few days of background re‑optimization, but heavy loads will still warm a Snapdragon 8 Elite phone.
Should I pick HyperOS 3 or stay on HyperOS 2?
HyperOS 3 on Xiaomi 15 brings Android 16 and long‑term support, while HyperOS 2.2 global builds are more mature and may feel slightly more predictable; if you value stability above new features, updating to the latest stable build for your branch and doing a clean install is usually safest.
Will flashing these ROMs void my warranty?
Official fastboot packages are genuine Xiaomi firmware, but unlocking the bootloader or using non‑standard flashing methods can affect warranty service depending on region, so checking local policy before proceeding is strongly recommended.
How do I confirm my phone is really codename dada?
Boot into fastboot mode, connect to a PC and run fastboot getvar product; Xiaomi 15 should report dada, matching firmware trackers and Xiaomi’s own codename lists for this model.
