This is a tool that can be used to dump the memory of a Samsung device inupload mode.

There are a few other tools that can do this, but I couldn't make them work (or they were way too slow), so I decided to write my own.

1. Download prebuiltlibusb

   curl -L https://github.com/libusb/libusb/releases/download/v1.0.26/libusb-1.0.26-binaries.7z --output libusb-1.0.26-binaries.7z

2. Extract the binaries

   7z x libusb-1.0.26-binaries.7z

3. If you are on Windows you might need to install a driver for your device. You can do that by runningZadig and installing the driver for your device:Zadig.

If your device's USB ID is not in thec_supported_devs array indumper.h you will need to add it.

1. Runlsusb and find your device's USB ID.

2. Add your device's USB ID to thec_supported_devs array indumper.h.

1. Runbuild.bat orbuild.sh depending on your platform.
2. The binary will be atbuild/upload_dumper.exe orbuild/upload_dumper.

1. Runupload_dumper with the following arguments to dump all memory (ranges are determined using the partition table extracted from the device):

   ./upload_dumper dump_all<output_directory>

2. Runupload_dumper with the following arguments to dump a specific partition:

   ./upload_dumper dump_index<output_file><index>

3. Runupload_dumper with the following arguments to dump a specific range of memory:

   ./upload_dumper dump_range<output_file><start_address><end_address>

Examples:

The following command will dump all memory to thedump directory.

./upload_dumper dump_all ./dump

The following command will dump the memory from0x8F000000 to0x8F010000 todump.bin.

./upload_dumper dump_range dump.bin 0x8F000000 0x8F010000

This one will dump the partition at index13 todump.bin.

./upload_dumper dump_index dump.bin 13

There are a few projects that I used as a reference (and to copy some code snippets :) for this project:

1. alex-segura/s9-sboot-emu
2. nitayart/sboot_dump
