小米、Redmi 与 POCO Root：先确认资格，再刷正确镜像

很多机型历史上有成熟方法，但要同时具备真实解锁资格、正确固件和当前设备支持，不能仅看系列名称。

MIUI was Xiaomi's Android skin from 2010-2023 — heavily customized, distinctive UI, large user base. HyperOS (announced October 2023, rolled out from late 2023 through 2024) is Xiaomi's successor — rebranded with deeper integration across Xiaomi's ecosystem (TVs, IoT, cars), more polish, AOSP-aligned where MIUI diverged. For rooting purposes: HyperOS uses similar firmware structure to late-MIUI; the rooting workflow is essentially identical — Mi Unlock Tool + fastboot + Magisk-patched boot.img. Some 2024+ HyperOS firmware introduced additional anti-modification checks; the community has caught up with these but expect minor procedural updates per HyperOS version. The transition is mostly seamless from a rooting perspective; the bigger user-facing change is UI/branding rather than rooting-relevant internals.

Most do, with proper setup. Standard 2026 stack: configure Magisk DenyList + Shamiko + Play Integrity Fix + reboot + verify Play Integrity Test passes BASIC and DEVICE. With this stack, most consumer banking + payment apps continue working: Google Pay variable per region; Indian UPI apps (PhonePe, Google Pay India, Paytm) variable per app + per Magisk version; Bangladesh mobile-money (bKash, Nagad, Rocket) variable. STRONG_INTEGRITY-requiring apps (HSBC UK, several BD/IN/PK banks, some EU banks) may still fail — install Tricky Store module for the additional layer; this handles a meaningful fraction of remaining cases. The honest 2026 caveat: Xiaomi rooting works well for most banking apps but more banking apps refuse on rooted Xiaomi than on rooted Pixel — Xiaomi's Play Integrity DEVICE verdict is harder to pass cleanly. Pre-flight test your specific banking apps before relying on a rooted Xiaomi for daily payments.

Anti-rollback (ARB) is a security feature on some Xiaomi devices that prevents flashing firmware older than a certain version. Once a device is on firmware version X with ARB level Y, flashing firmware older than Y is blocked at the bootloader — attempting to do so will hard-brick the device. ARB is most aggressive on China-region Xiaomi variants; less aggressive on global variants; nearly absent on India-region Redmi/POCO. Practical rooting implications: (1) When sourcing firmware for boot.img extraction, you must source firmware at-or-above your device's current ARB level — flashing older firmware will brick. (2) After rooting, you cannot downgrade past your current ARB level. (3) ARB level is stored in protected hardware and cannot be reverted. (4) For most users, ARB is not a problem — you root using current firmware and stay current. The risk emerges only when attempting to downgrade for specific reasons (older HyperOS version, older ROM compatibility); plan firmware sourcing carefully on China-region devices.

Manufacturer warranty: yes, typically voided by bootloader unlock. Per-region specifics: (1) China-region — Xiaomi's official Chinese warranty is strict; unlocked devices typically refused for warranty service. (2) India-region — Xiaomi India service centres are sometimes accommodating for hardware-defect claims regardless of unlock status; varies per service centre. (3) Global / EU — Xiaomi's official policy is void; EU consumer law (Sale of Goods Directive) provides hardware-defect statutory rights independent of bootloader status for EU purchases for the legal warranty period. (4) Bangladesh / Pakistan — local Xiaomi service centres widely accommodating for hardware claims regardless of unlock; varies per centre. (5) Out-of-warranty paid repair unaffected — Xiaomi service centres will accept paid repair regardless of unlock. The right framing: assume manufacturer warranty is gone; rely on EU consumer law for hardware defects in EU; budget for paid repair elsewhere.

All three are Xiaomi-owned brands using essentially the same Mi Unlock Tool + MIUI/HyperOS workflow for rooting. Practical differences: (1) Xiaomi-flagship line (Xiaomi 14, 13, etc.) — premium hardware, more aggressive ARB on some variants, most cooperative community resources; (2) Redmi mid/budget line — more model variations, some regional variants (Redmi-India) with slightly different firmware procedures; (3) POCO performance-mid line (POCO F-series, X-series) — historically more rooting-friendly target, large community on /r/PocoPhones and XDA. The rooting workflow is essentially identical across all three; the differences are in hardware tier, market positioning, and specific community-resource maturity per model. POCO X-series and F-series are commonly chosen by buyers explicitly looking for rooting-friendly hardware at lower price points.
