Qualcomm Sahara / Firehose Attack Client / Diag Tools

Why

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

Use LiveDVD (everything ready to go, based on Ubuntu):

User: user, Password:user (based on Ubuntu 22.04 LTS)

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
# Arch/Manjaro/etc
sudo pacman -S android-tools python python-pip git xz
sudo pacman -R modemmanager

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

Using serial port instead of usb

With Port autodetection

edl --serial

or Port name

edl --portname \\.\COM1

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)

Your device needs to have a usb pid of 0x9008 in order to make the edl tool work. If your device is semi bricked and entered the usb pid 0x900E, there are several options to get back the 0x9008 mode :

Use a edl cable (Short D+ with GND) and force reboot the phone (either vol up + power pressing for more than 20 seconds or disconnect battery), works with emmc + ufs flash (this will only work if XBL/SBL isn't broken)
If emmc flash is used, remove battery, short DAT0 with gnd, connect battery, then remove short.
If a ufs flash is used, things are very much more complicated. You will need to open the ufs die and short the clk line on boot, some boards have special test points for that.
Some devices have boot config resistors, if you find the right ones you may enforce booting to sdcard instead of flash.

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 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. Do that only when REALLY needed as it will print out everything happening!
