Warning: Avoid Bricks & Data Loss (sweet_k6a)​

• Flashing the wrong ROM (wrong codename, wrong region branch, or wrong flashing option) can soft‑brick or hard‑brick your smartphone.
• Do NOT flash "sweet" firmware on "sweet_k6a" (or reverse); users warn it can brick the phone into EDL mode requiring service restore.
• Fastboot flashing usually requires an unlocked bootloader, and data may be deleted depending on your choice—always back up first.
• Do not flash across different region branches unless you fully understand the risks (flash errors, vendor data loss, or bricking explicitly warned on ROM index sites).

3. Extract the .tgz file fully on your PC until you see the firmware folder and Mi Flash files.
4. Boot the Redmi Note 12 Pro 4G into Fastboot mode, connect to PC, and load the extracted ROM folder in Xiaomi Mi Flash Tool.
5. Flash carefully (backup first because data may be deleted), and expect longer first boot after clean reinstall.
