# 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 :)

## Installation

- Get python >= 3.7 64-Bit

Linux/Windows: 
```bash
cp Drivers/51-edl.rules /etc/udev/rules.d
cp Drivers/50-android.rules /etc/udev/rules.d
sudo apt install adb fastboot python3-dev python3-pip
sudo sudo apt install liblzma-dev
sudo apt purge ModemManager
python3 -m pip install -r requirements.txt
```

Mac:
```bash
brew install libusb
sudo python3 -m pip install -r requirements.txt```
```

Windows:
- Boot device into 9008 mode, install Qualcomm_Diag_QD_Loader_2016_driver.exe from Drivers\Windows
- Use Zadig 2.5 or higher, list all devices, select QUSB_BULK device and replace
  driver with libusb >= 1.2.6.0 one (will replace original driver)
- Get latest Zadig release [here] (https://zadig.akeo.ie/)

## Convert EDL loaders for automatic usage

- Make a subdirectory "newstuff", copy your edl loaders to this subdirectory
- ```./Loaders/fhloaderparse.py 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.py sniffeddata.bin```

## Run EDL (examples)

### Generic

- ```./edl.py -h``` -> to see help with all options
- ```./edl.py server --memory=ufs --tcpport=1340``` -> Run TCP/IP server on port 1340, see tcpclient.py for an example client
- ```./edl.py xml run.xml``` -> To send a xml file run.xml via firehose
- ```./edl.py reset``` -> To reboot the phone
- ```./edl.py rawxml <xmlstring>``` -> To send own xml string, example :
   ```./edl.py rawxml "<?xml version=\"1.0\" encoding=\"UTF-8\" ?><data><response value=\"ACK\" /></data>```
- ```./edl.py [anycommand] --debugmode``` -> enables Verbose. Only do that is REALLY needed as it will print out everything happening !

#### Dump memory (0x900E mode)
- ```./edl.py memorydump```

### Streaming mode (credits to forth32)

#### 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
- ```./edl.py --vid 1199 --pid 9070 --loader=loaders/NPRG9x35p.bin printgpt``` -> To show the partition table

#### Netgear MR1100
- run ```modem/boottodownload.py```, device will enter download mode (0x900E pid)
- ```./edl.py printgpt --loader=Loaders/qualcomm/patched/mdm9x5x/NPRG9x55p.bin```, device will reboot to 0x9008
- now use ./edl.py regulary such as ```./edl.py printgpt``` (do not use loader option)

#### ZTE MF920V, Quectel, Telit, etc.. Modem
- run ```modem/enableadb.sh```, or send to at port "AT+ZCDRUN=E", or send via ```./modem/diag.py -sahara```
- ```adb reboot edl```
- ```./edl.py printgpt``` -> To show the partition table

### QFIL in linux console (credits to LyuOnLine):

- For flashing full image:
   ```
   ./edl.py qfil rawprogram0.xml patch0.xml image_dir
   ```

## Install EDL loaders

- ```mkdir examples```
- Copy all your loaders into the examples directory
- ```./fhloaderparse.py 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 Diag port tools (examples)

For Oneplus 6T, enter *#801#* on dialpad, set Engineer Mode and Serial to on and try :

- ```./modem/diag.py -vid 0x05c6 -pid 0x676c -interface 0 -info```

### Usage

- ```./modem/diag.py -vid 0x1234 -pid 0x5678 -interface 0 -info``` -> Send cmd "00" and return info
- ```./modem/diag.py -vid 0x1234 -pid 0x5678 -interface 0 -spc 303030303030``` -> Send spc "303030303030"
- ```./modem/diag.py -vid 0x1234 -pid 0x5678 -interface 0 -cmd 00``` -> Send cmd "00" (hexstring)
- ```./modem/diag.py -vid 0x1234 -pid 0x5678 -interface 0 -nvread 0x55``` -> Display nvitem 0x55
- ```./modem/diag.py -vid 0x1234 -pid 0x5678 -interface 0 -nvbackup backup.json``` -> Backup all nvitems to a json structured file
- ```./modem/diag.py -vid 0x1234 -pid 0x5678 -interface 0 -efsread efs.bin``` -> Dump the EFS Modem partition to file efs.bin
- ```./modem/diag.py -vid 0x1234 -pid 0x5678 -interface 0 -efslistdir /``` -> Display / directory listing of EFS


## Issues

- Secure loader with SDM660 on Xiaomi not yet supported (EDL authentification)
- VIP Programming not supported (Contributions are welcome !)
- EFS directory write and file read has to be added (Contributions are welcome !)
