Install HyperOS 3 on POCO X3 – Complete Guide (Custom ROM Port)

Short summary: HyperOS 3 is not officially available for POCO X3. This guide covers installing an unofficial/custom HyperOS 3 port on POCO X3 (Surya/Karna) using TWRP/OrangeFox. Proceed at your own risk.

Pro tip: Read the full guide before starting. Keep a PC, USB cable and stable internet ready.

Why install HyperOS 3 on POCO X3?

HyperOS 3 is Xiaomi’s newer OS with smoother UI, refined animations, and improved battery management. Official support is limited to selected Xiaomi devices, but the custom ROM community often ports newer firmware to older devices. Installing a HyperOS 3 port can give POCO X3 a modern look, slimmer software footprint, and often better performance than older MIUI builds.

Important warning — read before continuing

Installing an unofficial port carries risks: it may void warranty, cause instability, break certain hardware features (NFC, camera modes, VoLTE), or brick your phone if steps are missed. Back up your data (TWRP Nandroid backup and store a copy on PC).

Supported POCO X3 models & verifying codename

POCO X3 comes in variants with different codenames. Most relevant variants:

POCO X3 NFC — codename surya
POCO X3 (non-NFC) — codename karna

How to check codename:

Dial: *#*#5646#*#*  OR use Device Info HW → System → Codename

Only flash a ROM that explicitly supports your codename.

Prerequisites (what you need)

Unlocked bootloader (official Mi Unlock method)
A compatible custom recovery (TWRP or OrangeFox for your codename)
HyperOS 3 ROM ZIP made for your device codename
Optional: Magisk ZIP if you want root
ADB & fastboot (Platform Tools) installed on PC
Full backup (TWRP Nandroid or export important files)

Download

Before starting, download and verify these files from trusted community sources:

HyperOS 3 ROM for POCO X3 (surya/karna) use vpn if link not working
TWRP or OrangeFox image for your model
Magisk ZIP (optional)

Step-by-step installation (general method)

Follow these exact steps and replace filenames with the ones you downloaded.

STEP 1 — Unlock bootloader

Enable Developer Options: Settings → About → tap MIUI/Build number multiple times.
Enable OEM unlocking and USB debugging.
Log in with your Mi account on the phone.
Use Mi Unlock Tool on PC to unlock the bootloader (this will wipe the device).

STEP 2 — Install TWRP/OrangeFox

Boot into Fastboot (Power + Volume Down) and run on PC:

fastboot flash recovery twrp-your-device.img
fastboot boot twrp-your-device.img

Important: Boot straight into recovery after flashing—do not let the phone boot normally until ROM flash completes.

STEP 3 — Backup & Wipe

In TWRP: Select Backup → make a full Nandroid (Boot, System, Data).
Wipe → Advanced Wipe: Dalvik/ART cache, System, Data. Do NOT wipe internal storage if you stored ROM there.

STEP 4 — Install ROM (and addons)

Transfer HyperOS3-for-poco_x3.zip to internal storage or use sideload.
In TWRP: Install → choose the ROM ZIP → Swipe to confirm flash.
If required, flash firmware/vendor ZIP, then Magisk (if you want root) and GApps only if ROM needs them.
Reboot System. First boot may take several minutes.

Troubleshooting & recovery

Bootloop: Reboot to TWRP → restore your Nandroid backup.
Missing features: Check ROM thread for known bugs and required firmware.
Stuck on logo — try wiping cache/dalvik or reflash ROM + firmware.

Tips to optimize after install

Disable unused startup apps in Settings → Apps.
Enable Battery optimizations and adaptive battery where available.
Install Magisk modules carefully (some may break system UI).
Keep a TWRP backup after you finish configuring the ROM.

FAQ

Is HyperOS 3 officially available for POCO X3?

No — you must use an unofficial community port. Always follow the developer’s instructions for that port.

Will I lose data?

Yes — unlocking the bootloader and flashing typically wipes data. Back up before proceeding.

Which POCO X3 variant do I have?

Use the codename check above. Flash only ROMs built for your codename (surya/karna).

Final notes

Installing HyperOS 3 through a custom port can breathe new life into older hardware, but it requires attention to detail. Always read and follow the ROM developer’s thread for device-specific instructions, required firmwares, and known issues. If you run into problems, community threads (XDA/Telegram/Reddit) are the best place to ask for device-specific help—share your device model, codename, exact ROM build, and logs if possible.

If you want, I can now:

Generate a device-specific command list for your exact POCO X3 variant (Surya or Karna).
Search community threads for the latest HyperOS 3 ports and compatible recoveries and paste the verified links.
