“Format All + Download” erases critical partitions like nvram (IMEI storage). Always use “Download Only” or “Firmware Upgrade” unless you have a full backup.
Use this only if you have the ROM files (system.img, boot.img) but lost the scatter text file.
If you have a working phone and root access:

| Risk | Consequence | Prevention |
|------|-------------|------------|
| Flashing wrong preloader | Hard brick (no response, no charging LED) | Never flash preloader unless you have a hardware programmer (e.g., Medusa Box) |
| Flashing wrong nvram | IMEI = 0 or 111111, no cellular signal | Always backup NVRAM first; never flash NVRAM from another device |
| Using mismatched scatter | Partition overlap → corrupted data | Triple-check model and firmware version |
| Interrupting flash | Incomplete write → brick | Use a stable PC, quality USB cable, fully charged battery |
Using the wrong scatter file is like using a map of New York to navigate London. You will end up corrupting the wrong partitions, resulting in a bricked device.
