How to fill out the configuration files?

The most challenging part of the packaging process is filling out the configuration files. You can use the lpdump command to query the required information, or extract it from the official EDL package (EDL.zip/META/dynamic_partitions_info.txt and ab_partitions.txt).

Additionally, I've written a setup.sh script that can quickly help you fill out the dynamic_partitions_info.txt and ab_partitions.txt configuration files.

cd Payload_Repack_Tool
./setup.sh
# Chinese version:
./setup_zh.sh
