Samsung Upload Mode Dumper

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

🔎 Acquiring Dependencies

Download prebuilt libusb

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

Extract the binaries
```
7z x libusb-1.0.26-binaries.7z
```
If you are on Windows you might need to install a driver for your device. You can do that by running Zadig and installing the driver for your device: Zadig.

If your device's USB ID is not in the c_supported_devs array in dumper.h you will need to add it.

Run upload_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>
```
Run upload_dumper with the following arguments to dump a specific partition:
```
./upload_dumper dump_index <output_file> <index>
```
Run upload_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 the dump directory.

./upload_dumper dump_all ./dump

The following command will dump the memory from 0x8F000000 to 0x8F010000 to dump.bin.

./upload_dumper dump_range dump.bin 0x8F000000 0x8F010000

This one will dump the partition at index 13 to dump.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:
