You use a scatter file to write data to the device. You use an addr file to read data from the device—specifically when performing a readback operation. Why Do You Need an MTK Addr File? 1. Performing a Full Flash Dump (Read Back) When you want to back up the entire firmware of a working MediaTek phone, SP Flash Tool requires a readback operation. The readback function does not parse partition names; it only wants raw address ranges.

| Feature | MTK Addr File | MTK Scatter File | |--------|--------------|------------------| | | ❌ No | ✅ Yes (eg., preloader , lk , boot ) | | Used by SP Flash Tool for "Download" | ❌ No | ✅ Yes | | Used by SP Flash Tool for "Read Back" | ✅ Yes | ❌ No (unless converted) | | Human-readable partition info | ❌ Minimal | ✅ Yes | | Typical file extension | .addr | .txt or .xml |

0x380000 0x500000 Read back this region to get a nvram.bin backup. If preloader is corrupted, you need to write a known-good preloader at address 0x0 . However, writing requires a scatter file; but you can use an addr file to first read back the corrupted region for analysis, compare it to a working image, and then use a patched scatter file to flash. 3. Combining Multiple Addr Files For complex operations (e.g., dumping only boot and recovery ), create separate addr entries:
