Flashing Requirements
- Only use these ROMs on devices that report lake when you run fastboot getvar product in fastboot mode.
- Bootloader must be unlocked before flashing any fastboot `.tgz` package; locked devices should use official OTA/recovery ZIPs instead.
- A Windows PC, Xiaomi USB drivers, Mi Flash Tool (or manual fastboot), a reliable USB‑C cable and at least 15–20 GB of free storage.
- Battery charged to at least 60 % to avoid shutdowns during flashing and to reduce extra lag when the CPU throttles at very low charge.
- Full backup of photos, chats and documents because recommended “clean all” flashes erase internal storage completely.
How to Flash the Firmware
Fastboot ROMs (.tgz) with Xiaomi Mi Flash Tool
- Download the correct lake_…_images_… fastboot ROM for your region and extract it until you see the images folder and flash_all*.bat scripts.
- Install Xiaomi Mi Flash Tool and drivers on your PC, then point Mi Flash to the extracted firmware folder.
- Boot your phone into fastboot mode, connect it via USB and click “Refresh” in Mi Flash to confirm the device is detected.
- Select the clean all option for a fresh install, press “Flash” and wait patiently until the tool shows a success message.
- Reboot the phone and let HyperOS 2 finish optimising apps; performance should become smoother after the first few minutes of use.
If you prefer visual, step‑by‑step instructions, follow these detailed guides: how to flash with Xiaomi Mi Flash Tool, how to use a flash_all.bat fastboot script, and how to install OTA updates via recovery/ADB sideload.
