# Qualcomm Sahara / Firehose Attack Client / Diag Tools
(c) B. Kerler 2018-2021

## Why

- Because we'd like to flexible dump smartphones
- Because attacking firehose is kewl
- Because memory dumping helps to find issues :)

### Use Re LiveDVD (everything ready to go, based on Ubuntu):
[Download Re Live DVD V2](https://drive.google.com/file/d/1VUK0toC6I0jhJ4ZTFPREhSXFTkSe9_gl/view?usp=sharing)

## Installation

### Linux (Debian/Ubuntu/Mint/etc): 
```bash
# Debian/Ubuntu/Mint/etc
sudo apt install adb fastboot python3-dev python3-pip liblzma-dev git
sudo apt purge modemmanager
# Fedora/CentOS/etc
sudo dnf install adb fastboot python3-devel python3-pip xz-devel git

sudo systemctl stop ModemManager
sudo systemctl disable ModemManager
sudo apt purge ModemManager

git clone https://github.com/bkerler/edl.git
cd edl
git submodule update --init --recursive
sudo cp Drivers/51-edl.rules /etc/udev/rules.d
sudo cp Drivers/50-android.rules /etc/udev/rules.d
python setup.py build
sudo python setup.py install
```

### macOS:
```bash
brew install libusb git

git clone https://github.com/bkerler/edl.git
cd edl
git submodule update --init --recursive
python setup.py build
sudo python setup.py install
```

### Windows:
#### Install python + git
- Install python 3.9 and git
- If you install python from microsoft store, "python setup.py install" will fail, but that step isn't required.
- WIN+R ```cmd```

#### Grab files and install
```
git clone https://github.com/bkerler/edl
cd edl
git submodule update --init --recursive
pip3 install -r requirements.txt
```

#### Get latest UsbDk 64-Bit
- Install normal QC 9008 Serial Port driver (or use default Windows COM Port one, make sure no exclamation is seen)
- Get usbdk installer (.msi) from [here](https://github.com/daynix/UsbDk/releases/) and install it
- Test on device connect using "UsbDkController -n" if you see a device with pid 0x9008
- Works fine under Windows 10 and 11 :D

------------------------------------------------------------------------------------------------------------------------------------
## Get Loaders
You should get these automatically if you do a ``` git submodule update --init --recursive ```
or from [here](https://github.com/bkerler/Loaders)

## Convert own EDL loaders for automatic usage

- Make a subdirectory "newstuff", copy your edl loaders to this subdirectory
- ```fhloaderparse newstuff Loaders```

- or sniff existing edl tools using Totalphase Beagle 480, set filter to ```filter({'inputs': False, 'usb3': False, 'chirps': False, 'dev': 26, 'usb2resets': False, 'sofs': False, 'ep': 1})```, export to binary file as "sniffeddata.bin" and then use ```beagle_to_loader sniffeddata.bin```


## Install EDL loaders

- ```mkdir examples```
- Copy all your loaders into the examples directory
- ```fhloaderparse examples Loaders``` -> will autodetect and rename loader structure and copy them to the "Loaders" directory
- Or rename Loaders manually as "msmid_pkhash[8 bytes].bin" and put them into the Loaders directory

------------------------------------------------------------------------------------------------------------------------------------

## Run EDL (examples)

### Generic

- ```edl -h``` -> to see help with all options
- ```edl server --memory=ufs --tcpport=1340``` -> Run TCP/IP server on port 1340, see tcpclient.py for an example client

------------------------------------------------------------------------------------------------------------------------------------
### Streaming mode (credits to forth32)

#### Enter streaming mode

##### Sierra Wireless Modem
- Send AT!BOOTHOLD and AT!QPSTDLOAD to modem port or use ```modem/boottodwnload.py``` script
- Send AT!ENTERCND="A710" and then AT!EROPTION=0 for memory dump

- run ```boottodownload```, device will enter download mode (0x900E pid)
- ```edl printgpt --loader=Loaders/qualcomm/patched/mdm9x5x/NPRG9x55p.bin```, device will reboot to 0x9008
- now use edl regulary such as ```edl printgpt``` (do not use loader option)

##### ZTE MF920V, Quectel, Telit, etc.. Modem
- run ```enableadb```, or send to at port "AT+ZCDRUN=E", or send via ```qc_diag -sahara```
