Xiaomi 13 Ultra (ishtar) HyperOS 3 & HyperOS 2 Fastboot ROM + Xiaomi.eu ROM & TWRP (Android 16 / 15)
Xiaomi 13 Ultra is a flagship phone with a 6.73‑inch WQHD+ LTPO AMOLED display, Snapdragon 8 Gen 2 processor, 50MP Leica quad‑camera system and a 5000mAh battery with 90W wired and wireless charging support, designed for heavy photography, gaming and pro‑level use. On such a high‑end device, advanced users frequently rely on full HyperOS Fastboot ROMs to fix bootloops, clean up messy update histories, or switch between China and Global/EEA firmwares, and many also combine stock ROMs with Xiaomi.eu builds and TWRP for more control.
This page is prepared after reviewing HyperOS firmware trackers, Xiaomi 13 Ultra (ishtar) ROM archives, and Xiaomi.eu and TWRP device pages, so that every download listed matches Xiaomi 13 Ultra (codename ishtar) only and uses confirmed version information.
File Selection Guide.
The build numbers and filenames clearly identify Xiaomi 13 Ultra, the region, HyperOS branch (2 or 3) and Android level (15 or 16); checking these before flashing helps avoid cross‑device or cross‑region mistakes.
- Device and codename: HyperOS sites, XM Firmware Updater and MiFirm all list Xiaomi 13 Ultra with codename ishtar, and the stock Fastboot ROMs here use
ishtar_images_...orishtar_*_global_images_...in the filename. - Region suffix: The version endings follow Xiaomi’s standard pattern:
CNXM= China,MIXM= Global,EUXM= EEA,RUXM= Russia,TWXM= Taiwan. - HyperOS & Android level: Trackers show OS2.0.20x/208.0.VMA* builds for ishtar as HyperOS 2 / Android 15, and OS3.0.3.0.WMACNXM as HyperOS 3 / Android 16; the filenames confirm with
_15.0_or_16.0_. - ROM type: For OS3.0.3.0.WMACNXM, XM Firmware Updater lists both Recovery and Fastboot packages; the file here is the Fastboot ROM (
...images_....tgz) while Xiaomi.eu provides a separate custom.zipbased on the same version. - Xiaomi.eu and TWRP: Xiaomi.eu HyperOS ROMs for ISHTAR are custom ROMs built on top of official bases (in this case OS3.0.3.0.WMACNXM Android 16), and
twrp-3.7.1_12-v9.0_A15-ishtar-skkk.imgis a community TWRP image targeted at ishtar (Android 15/HyperOS 2 era).

Flashing Requirements
Fastboot flashing of HyperOS 2/3 often performs a clean install that erases user data, so creating full backups (cloud or local) is strongly recommended before proceeding.
A Windows PC, a reliable USB‑C cable and correctly installed Xiaomi/Qualcomm drivers are needed for Mi Flash Tool or Fastboot to detect Xiaomi 13 Ultra in Fastboot mode.
Bootloader unlocking is typically required for installing Fastboot or custom ROMs on Xiaomi 13 Ultra, and Xiaomi’s unlock tool and documentation explain the official steps and waiting periods.
The phone battery should be charged to at least 50%, and the USB connection must remain stable during flashing to avoid corruption or a hard‑brick.
📱How to Flash the Firmware
Method 1: HyperOS Fastboot ROM via Mi Flash Tool
- Download and extract: Save the matching Fastboot ROM (for example
ishtar_global_images_OS2.0.208.0.VMAMIXM_20251024.0000.00_15.0_global_2081c9f3c3.tgzorishtar_images_OS3.0.3.0.WMACNXM_20251202.0000.00_16.0_cn_3614ef8aba.tgz) and extract it to a folder on the PC. - Enter Fastboot mode: Power off Xiaomi 13 Ultra, boot into Fastboot mode and connect it to the computer via a stable USB‑C cable.
- Load ROM in Mi Flash: Open Mi Flash Tool, point it to the extracted ishtar ROM directory and confirm that the device is recognized.
- Flash HyperOS: Choose the appropriate flash option (clean flash usually wipes data), click “Flash” and wait until the tool finishes installing the selected HyperOS version.
- Reboot and set up: Allow the phone to reboot automatically and complete the Android 15 or 16 HyperOS setup process before restoring apps and data.

Method 2: Fastboot Script (flash_all.bat style)
- Unpack the ROM: Extract the
.tgzHyperOS ROM and locate scripts such asflash_all.batin the ishtar ROM folder. - Prepare the phone: Boot Xiaomi 13 Ultra into Fastboot mode and connect it to the PC; verify Fastboot recognizes the device.
- Run the script: Execute the appropriate script (
flash_all.batfor full wipe) to flash all required partitions for OS2.0.x.x or OS3.0.3.0. - Wait for completion: Keep the cable attached until the script reports success and the phone is ready to reboot.
- Boot into HyperOS: Allow extra time for the first boot into HyperOS 2 or 3, then finish setup.
More details about using flash_all.bat and related scripts are available here: How to Flash Stock Firmware Using a Fastboot Script (flash_all.bat)
Method 3: Xiaomi.eu HyperOS 3 ROM (general outline)
- Confirm base: Check that the Xiaomi.eu package name
xiaomi.eu_ISHTAR_OS3.0.3.0.WMACNXM_16.zipmatches the intended device (ISHTAR) and base build (OS3.0.3.0.WMACNXM Android 16). - Prepare recovery/PC: Follow Xiaomi.eu install notes for Xiaomi 13 Ultra, which generally require an unlocked bootloader and either TWRP or a Fastboot installer.
- Backup and wipe: Create backups, then wipe the recommended partitions according to Xiaomi.eu instructions before installing the ROM zip.
- Flash Xiaomi.eu ROM: Install the ROM through the supported method (custom recovery or PC installer) as documented in Xiaomi.eu’s ishtar threads.
- Reboot into Xiaomi.eu HyperOS: Reboot, wait for the first Xiaomi.eu boot on HyperOS 3, then sign in and restore data.
Exact Xiaomi.eu flashing steps can change over time, so checking the latest Xiaomi 13 Ultra (ishtar) threads on Xiaomi.eu forums is recommended before installation.
Frequently Asked Questions (FAQs)
How can the correct Xiaomi 13 Ultra (ishtar) HyperOS Fastboot ROM be chosen?
The ROM suffix (CNXM, MIXM, EUXM, RUXM, TWXM) should match the suffix shown in the current build in the “About phone” page; using the same region family helps maintain OTA and feature compatibility.
Is OS3.0.3.0.WMACNXM confirmed as Xiaomi 13 Ultra China HyperOS 3 (Android 16)?
XM Firmware Updater and MiFirm list OS3.0.3.0.WMACNXM as “Xiaomi 13 Ultra China – HyperOS 3.0 – Android 16 – Recovery/Fastboot” and show the matching Fastboot filename ishtar_images_OS3.0.3.0.WMACNXM_..._16.0_cn....
Can Global Xiaomi 13 Ultra units flash the China HyperOS 3 OS3.0.3.0.WMACNXM Fastboot ROM safely?
HyperOS pages label OS3.0.3.0.WMACNXM as a China CNXM build; no official guidance endorses cross‑region flashing, and doing so can affect language defaults, services and OTA behaviour, so it is only for users who fully understand the risks.
Does flashing HyperOS 2/3 Fastboot ROM on Xiaomi 13 Ultra always wipe user data?
Fastboot ROM and flash_all.bat procedures are documented as clean installs that usually erase user data, and standard Xiaomi flashing guides strongly advise backing up first.
Is Xiaomi 13 Ultra (ishtar) confirmed for HyperOS 3 and Android 16?
Eligible device lists and firmware trackers include Xiaomi 13 Ultra among HyperOS 3 / Android 16 devices, and OS3.0.3.0.WMACNXM appears as a stable Android 16 release.
Is the xiaomi.eu_ISHTAR_OS3.0.3.0.WMACNXM_16.zip ROM official?
No; Xiaomi.eu ROMs are community‑built using stock bases. The ISHTAR OS3.0.3.0.WMACNXM package is described as a HyperOS 3 custom ROM for Xiaomi 13 Ultra, not an official Xiaomi firmware.
Can the TWRP 3.7.1 ishtar image be used on HyperOS 3 (Android 16)?
The filename indicates targeting for Android 15/HyperOS 2, and there is no official confirmation of Android 16 support, so compatibility with OS3.0.3.0 should be verified in the maintainer’s thread before use.
