What HyperOS changed
HyperOS reworked the recovery environment and the Mi account verification handshake. Methods that relied on older MIUI recovery menus, or on sideloading through the pre-setup wizard, stopped working on a large share of devices upgraded to HyperOS.
The enduring route is chipset-level: MediaTek devices expose BROM/Preloader, and many Qualcomm devices expose fastboot. FRPB drives those transports directly, which is why it continues to work where menu-based guides do not.
Pick the right transport for your chipset
Getting this wrong is the most common cause of a failed Xiaomi FRP attempt. A MediaTek handset will never appear on a fastboot scan, and a Qualcomm handset will never answer a BROM handshake — they are different silicon and different boot ROMs.
FRPB probes the USB vendor ID and interface class and tells you which transport the device is actually offering. You do not have to guess; read the detected mode before continuing.
- 1MediaTek (Helio / Dimensity): use the BROM / Preloader path — hold Volume Up + Volume Down and connect USB.
- 2Qualcomm (Snapdragon): use fastboot — Volume Down + Power.
- 3Uncertain? Let FRPB detect first; it reports the vendor before running anything.
MediaTek BROM walkthrough
BROM mode is the Boot ROM: a tiny first-stage loader burned into the chip that runs before any firmware. It is reachable even when the phone cannot boot, which makes it the most reliable path for a locked MediaTek Xiaomi.
Windows must detect a MediaTek USB Port (often on a COM port). FRPB's detector specifically watches for the MediaTek vendor ID and treats the Bluetooth and virtual COM ports your PC also owns as irrelevant — so it will not attach to a headset by mistake.
After the reset
Once the account lock is cleared the device boots to the setup wizard. Connect to Wi-Fi there and sign in with the owner's own Google account — you do not need the previous Mi account, but you do need a Google account to complete Android setup.
If the device immediately re-locks, it was wiped while still signed in to the old Mi account. Re-run the operation after a fresh wipe rather than repeating it on the same state.
Safety, legality and when to stop
FRPB is intended strictly for authorised device owners and licensed repair professionals. You must own the device or hold explicit written permission from its owner. Using an FRP bypass tool on hardware you do not own may defeat an anti-theft control and can be illegal in your jurisdiction.
Stop and reassess if the device reports a bootloader state you did not expect, if the model or chipset FRPB detects does not match the handset in front of you, or if the operation halts mid-way. A mismatched firmware package is the single most common cause of a hard brick — abandoning an operation is always cheaper than recovering from one.
