Xiaomi 17 ultra users commonly run into the device stuck in EDL mode, especially after downgrading the firmware. The stock ROM below is a direct fix for this. This build is made specifically for the Chipset chipset, so confirm your exact model number (e.g. 2512BPNDAG - Global, 2512BPNDAC - China, 2512BPNDAI - India, 25128PNA1G - Leitzphone Global, 25128PNA1C - Leica China) before downloading.
If your Xiaomi 17 ultra (codename: nezha) is stuck on the Mi logo, stuck in a bootloop, showing a dead boot screen, or you flashed a custom ROM and now want to get back to MIUI/HyperOS, you're in the right place. Below you'll find every available fastboot and recovery firmware version for this device, along with working download servers and a flashing walkthrough that doesn't skip steps.
Before you pick a file: fastboot flashing means a full reset, so use it when the phone is genuinely stuck or dead. If you're just trying to repair the system without losing data, go with the recovery ROM instead.

Fastboot vs Recovery ROM — Which One Do You Need?
This trips up a lot of people, so here's the difference. A fastboot ROM is flashed from a PC using Mi Flash Tool and completely resets the device — the right pick when you're dealing with a bootloop, dead boot, or a phone that won't start. A recovery ROM is flashed straight from the phone's Mi Recovery menu and is built for updating, downgrading, or fixing software issues while keeping your data intact (though a backup never hurts).

Downloading in multiple parts? Keep every part inside the same folder before extracting — the archive won't open correctly if a part is missing.
Tools You'll Need
Get the flashing tool and the right USB driver set up on your PC before you start — in most cases, a failed flash has more to do with a missing driver than with the firmware file.
How to Flash Xiaomi 17 ultra Using Mi Flash Tool
- Download the fastboot ROM and extract it fully — don't skip extraction, Mi Flash Tool won't read a zipped folder.
- Install Mi Flash Tool from the link above and open it.
- Power off the phone, then hold Volume Down + Power together to boot into Fastboot mode.
- Connect the phone to your PC using a good-quality USB cable — cheap cables are a common cause of connection drops mid-flash.
- In Mi Flash Tool, click "Select" and point it to the extracted firmware folder.
- Once the COM port is detected, hit "Flash" and let it run — don't disconnect the phone during this step.
- The phone will reboot on its own once flashing finishes. First boot can take a few minutes longer than usual, so give it time.
Common Flashing Errors and How to Fix Them
"Auth file needed" — this usually shows up when the connected Mi account isn't authorized for flashing. You'll need an authorized account, or a test-point based flash for unlocked devices.
"COM port not detected" — almost always a driver issue. Install the Qualcomm/MediaTek USB driver from the link above, then put the phone back into EDL or Fastboot mode and try again.
"Flashing failed" partway through — try a different USB cable or port first; if that doesn't help, re-extract the firmware in case a file got corrupted during download.
Frequently Asked Questions
Is this firmware official?
Yes, these are unmodified stock builds pulled directly from Xiaomi's own update servers.
Will flashing delete my data?
Fastboot flashing wipes the device, so back up anything important first. Recovery flashing is less destructive but a backup is still a good idea.
My model number doesn't match exactly — can I still use this?
Always double-check the codename against nezha from the table. Flashing the wrong region or variant's firmware can leave the phone unusable.
How to Unlock Bootloader on Xiaomi 17 ultra
Before you start: Unlocking erases all data on the phone and lowers its security. Back up first.
Steps:
- Log in to your Mi account on the phone.
- Enable Developer options: Settings → About phone → tap OS/MIUI version 7 times.
Bind your account: Settings → Additional settings → Developer options → Mi Unlock status → Add account and device. This needs a SIM card and mobile data turned on.
- Download the Mi Unlock tool on your PC and sign in with the same Mi account.
- Enter Fastboot mode: power off the phone, then hold Power + Volume Down.
- Connect the phone to the PC by USB and click Unlock in the tool.
Good to know:
- Xiaomi usually enforces a waiting period (often 72 to 168 hours). The tool will tell you how long, and the account must stay bound to the phone during that time.
- Newer HyperOS versions have stricter unlock rules in some regions, so check Xiaomi's official unlock page for your region.
- After unlocking, some banking or payment apps may stop working, and Widevine L1 (HD streaming) may be lost.
- Don't flash any custom ROM or tool on a phone until you've found a confirmed guide for that exact model on XDA or the Xiaomi community.
If you hit an error like "Couldn't verify device" or a waiting-time message, let us know in the comments and we'll help.
