About this MTK SP Flash Tool Readback feature file generator

Link to the script Github repo: https://github.com/Eb43/readbackbackup/

Phones on MTK processors (typically Xiaomi, Poco, Redmi, Vivo, Oppo, Realme, Motorola, Nokia, Alcatel, Techno, ZTE) can be fully backed up woth the use of SP Flash Tool utility. This backup can be used for restoring phone's functionality after major problews with its firmware, including full dead brick (wrong flash of boot.img, preloader.bin) that does not react on buttons no logo, no charging sign. The NVRAM and NVDATA partitions that contain IMEI numbers, reuired for the phone operation, can be backed up.

In order to make SP Flash Tool functional a phone must have an unlocked bootloader. Not all smartphone vendors allow to unlock bootloader. The butloader has to be unlocked when the phone is functioning normally. Additionally, ensure your phone's MTK processor has available MTK bypass. New MTK processors are locked for low-level connection to PC.

The script takes the data on partition's offset and partition length from the Scatter.txt file, which is unique for each smarphone model. The Scatter file can be obtained from the official firmware for the smartphone.

Take the output of the script and paste it into the readback_ui_bak.xml file located in the the SP flash tool directory. MTK SP Flash Tool Readback feature file generator

Note the preloader readback adress should be added manually, since it is located in other part of the phone's NAND flash.

The readback_ui_bak.xml file is created automatically by the SP flash tool on any edit on the Readback tab. Ensure your file follows the structure. Verify the backup folder path leads to an existing folder on your disk.
