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):

Installation

Linux (Debian/Ubuntu/Mint/etc):

# 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:

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 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

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
  • edl xml run.xml -> To send a xml file run.xml via firehose
  • edl reset -> To reboot the phone
  • edl rawxml <xmlstring> -> To send own xml string, example : edl rawxml "<?xml version=\"1.0\" encoding=\"UTF-8\" ?><data><response value=\"ACK\" /></data>
  • edl [anycommand] --debugmode -> enables Verbose. Only do that is REALLY needed as it will print out everything happening !
