Bootloader unlock on Xiaomi
All Xiaomi-family unlocks run through the official Mi Unlock tool with a bound Mi account and a mandatory waiting period (historically 72 hours to 30 days). HyperOS added stricter account eligibility rules; nothing legitimate skips the wait.
Platform notes
Qualcomm Snapdragon platforms are the best-supported in the root community: fastboot works as documented, and even a failed flash can usually be recovered through EDL (9008) emergency mode.
Before you start
- Bootloader unlocking factory-resets the device on almost all models — back up everything first.
- Never use the "clean all and lock" option in Mi Flash unless deliberately re-locking on full stock firmware — it is the most common Xiaomi hard-brick cause.
- Anti-rollback protection makes downgrading firmware dangerous on this brand; always flash equal-or-newer versions.
FAQ
Can I root the Xiaomi Redmi S2 (Redmi Y2)?
Yes. The bootloader must first be unlocked with the official Mi Unlock tool, which requires a bound Mi account and a mandatory waiting period. After the unlock, root is Magisk via patched boot image (fastboot).
Does the Xiaomi Redmi S2 (Redmi Y2) support custom recovery (TWRP)?
Popular Xiaomi, Redmi and POCO models usually get TWRP or OrangeFox builds — check that one exists for this exact codename. A custom recovery is optional for root: after the Mi Unlock waiting period, Magisk installs by flashing a patched boot image over fastboot.
Will root the Xiaomi Redmi S2 (Redmi Y2) void my warranty?
Xiaomi will generally treat a rooted Xiaomi Redmi S2 (Redmi Y2) as outside warranty while it is modified. Restoring full stock firmware before a service visit usually restores normal treatment in practice, and consumer law in some regions (such as the EU) may still cover defects unrelated to root.
What Android version does the Xiaomi Redmi S2 (Redmi Y2) run?
It runs Android 8.1 (Oreo), upgradable to Android 9, MIUI 12. The specifications table on this page lists the full software details.
