Crucial Warning: Strictly verify your phone is the standard 4G Xiaomi Mi Mix 3 ('perseus', Snapdragon 845). NEVER flash these packages onto the Xiaomi Mi Mix 3 5G ('andromeda', Snapdragon 855 + X50 modem, which also drops wireless charging coils). Always select 'clean all' in Mi Flash on cross-region installs—choosing 'clean all and lock' on an imported China M1810E5A locks recovery in an error loop.

High-Level Restoration Roadmap for perseus
- Confirm your unit reports codename "perseus" (4G Snapdragon 845), never Mi Mix 3 5G "andromeda"
- Download the matching Fastboot .tgz, OTA .zip, Xiaomi.eu ZIP, or Official TWRP 3.7.0_9-0 .img
- Verify MD5 hashes and double-extract Fastboot .tgz files with 7-Zip into C:\perseus\
- Unlock the bootloader via Mi Unlock and follow the FlashGuideHub Fastboot & vbmeta guide
- Wait up to 10 minutes on first startup while Android 10 MIUI 12 / 12.5 rebuilds ART caches
perseus vs 5G andromeda & Anti-Rollback Pre-Checks
- Verify hardware codename is 'perseus' (Snapdragon 845) via 'fastboot getvar product'—never 'andromeda' (Mi Mix 3 5G Snapdragon 855).
- Check Android 10 Anti-Rollback state ('fastboot getvar anti') before moving between older MIUI 10/11 images and final QEE* builds like perseus_images_V12.5.1.0.QEECNXM_20210704.0000.00_10.0_cn_1d961fefc4.tgz.
- Note recovery ecosystem support: only Official TWRP (twrp-3.7.0_9-0-perseus.img) is officially maintained for perseus; OrangeFox and PitchBlack Recovery Project do not publish official builds for this board.
- Disable Android Verified Boot or format internal /data in TWRP if switching from Global MIUI 12.0 onto xiaomi.eu_multi_MIMix3_V12.5.1.0.QEECNXM_v12-10.zip.
- Check MD5 hashes carefully after downloading 2.6 GB+ archives before unpacking twice with 7-Zip onto C:perseus.
Board Codename, Region Branch & TWRP Compatibility Notes
Unlocked Xiaomi Mi Mix 3 (perseus) phones accept full Fastboot .tgz archives, Official TWRP 3.7.0_9-0, and Xiaomi.eu MIUI 12.5 installs cleanly. Snapdragon 845 enforces Xiaomi Anti-Rollback (ARB) checks as well as online Xiaomi Service Account authorization in Qualcomm EDL 9008 mode.

Mi Mix 3 Hardware Architecture & Build Branch FAQ
Although both phones share a nearly identical magnetic-slider exterior, the 4G Mi Mix 3 (perseus) runs Snapdragon 845, includes a 3,200 mAh battery with 10W Qi wireless charging, and reached Android 10 (MIUI 12/12.5), whereas the Mi Mix 3 5G (andromeda) switched to Snapdragon 855 with a Qualcomm X50 5G modem, omitted wireless charging coils to fit a 3,800 mAh cell, and remained on Android 9 Pie. Cross-flashing their images bricks the board.
In Xiaomi's seven-character build code, leading Q signifies Android 10.0 (Q), EE identifies the perseus Mi Mix 3 hardware platform, CN/MI/RU mark China, Global, and Russia channels respectively, and XM denotes an unlocked retail release.
Xiaomi kept Android 10.0 as the underlying base across all three branches, pushing a final China-only MIUI 12.5 UI refinement (V12.5.1.0.QEECNXM) in July 2021 after retiring Global (V12.0.2.0.QEEMIXM) and Russian (V12.0.3.0.QEERUXM) branches in November 2020. Global owners wanting MIUI 12.5 features with Google services commonly install xiaomi.eu_multi_MIMix3_V12.5.1.0.QEECNXM_v12-10.zip.
No. Neither the OrangeFox maintainer portal nor PitchBlack Recovery Project (PBRP) maintains an official device tree for perseus. TeamWin's official release twrp-3.7.0_9-0-perseus.img (64.00 MB) is the standard supported custom recovery for encrypted Android 10 installs and Xiaomi.eu ZIP flashing.
