The new rules include a single device limitation each Xiaomi account can now unlock only one device per year, down from three previously. Users must complete the entire process on one device, from answering eligibility questions through unlocking and post-unlock usage. After receiving approval, you have only 336 hours (14 days) to complete the binding and unlocking process before permissions expire.
Perhaps most frustratingly, Xiaomi now requires users to pass a mandatory quiz demonstrating their understanding of unlocking risks. The system also imposes waiting periods of 72 to 168 hours depending on the device. Some users report the application quota limit gets reached quickly each day, requiring attempts precisely at midnight Beijing time.
For Xiaomi firmware and flash files, the devices still work well once unlocked. The custom ROM scene remains active, with Xiaomi.eu offering enhanced versions of the official software and LineageOS supporting many models. SP Flash Tool handles MediaTek-based Xiaomi devices effectively.
The challenge is getting to that point. If a customer needs quick turnaround on a Xiaomi bootloader unlock, set realistic expectations about the timeline.
