Which ROM Does My Mi 11i Need?

Open Settings → About phone and look at the OS version. The two letters before XM at the end show your region:

Not sure which ROM you have? Paste the version from Settings → About phone to see its region, Android version and whether a newer build exists.

Check

Install a ROM of the same region your phone already runs. Officially, a different region needs an unlocked bootloader and a Fastboot ROM. Never flash a China (CN) ROM on a Global, EEA, India or other international phone: on some models it hard-bricks the phone.

How to Install Mi 11i Firmware

Recovery ROM (no PC, keeps your data)

1. Download the Recovery ROM (.zip) for exactly the region your phone runs now and copy it anywhere in the internal storage (for example Download). Don’t unpack it.
2. Open Settings → About phone and tap the OS version card. Tap the large HyperOS logo about 7–10 times until a message says extra features are enabled.
3. Tap the three dots → Choose update package, select the ZIP and wait until the phone installs it and reboots.

The updater only installs a build that is newer than yours and already public for your region. Pilot builds are often refused with “Installation of this software version is prohibited”: then wait for the wider release. More help: update not showing? install it manually.

Fastboot ROM (PC, clean install)

1. Unlock the bootloader first: HyperOS bootloader unlock guide.
2. Install ADB, Fastboot and USB drivers and Mi Flash Tool.
3. Extract the .tgz with 7-Zip to a short path without spaces or non-Latin characters (for example C:\rom). Deleting flash_all_lock.bat from the folder rules out an accidental relock. Boot the phone into Fastboot (Power + Volume Down) and check the codename with fastboot getvar product: it must say haydn.
4. Select the ROM folder in Mi Flash, choose Clean all and click Flash.

Warning: don’t edit or delete the checks at the top of flash_all.bat (codename and anti-rollback). Use Clean all and lock only with an unmodified official ROM that matches the phone’s market: a China ROM on a China unit, or an international ROM (Global, EEA, India…) on an international unit. Relocking a mismatched phone usually leaves it unbootable. Don’t relock right after a downgrade from HyperOS 4 to HyperOS 3.

Are these files official?

Yes. Every download goes straight to Xiaomi’s servers (bigota.d.miui.com or Xiaomi’s Aliyun storage). We don’t host or modify the files. Compare the checksum shown on the download page after downloading.

Recovery or Fastboot ROM: which one should I download?

Use the Recovery ROM to update without a PC and keep your data. Use the Fastboot ROM with Mi Flash to fix a bootloop, change region or do a clean install. It needs an unlocked bootloader and erases the phone.
