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 :)

Installation

Get python >= 3.7 64-Bit
Add "blacklist qcserial" as last line to /etc/modprobe.d/blacklist.conf
Copy Drivers/51-edl.rules to /etc/udev/rules.d
Copy Drivers/50-android.rules to /etc/udev/rules.d
sudo apt install adb
sudo apt install fastboot
sudo sudo apt install liblzma-dev

Linux/Windows:

"python -m pip install -r requirements.txt"

Windows:

Boot device into 9008 mode, install Qualcomm_Diag_QD_Loader_2016_driver.exe from Drivers\Windows, then install libusb-win32-devel-filter-1.2.6.0.exe. Run Filter Wizard, "Install a device filter", select "Qualcomm HS-USB QDLoader 9008" and press "Install" to install libusb filter driver otherwise we won't detect the device. Then use the edl tool. or
Use Zadig 2.4 or higher, list all devices, select QUSB_BULK device and replace driver with libusb 1.2.6 one (will replace original driver)

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 ' -> To send own xml string, example : '''bash ./edl.py rawxml "<response value="ACK" />" '''
"./edl.py [anycommand] --debugmode" -> enables Verbose. Only do that is REALLY needed as it will print out everything happening !

"./edl.py printgpt --memory=ufs" -> to print gpt of all lun
"./edl.py rf lun0.bin --memory=ufs --lun=0" -> to dump whole lun 0
"./edl.py rf flash.bin --memory=ufs" -> to dump all luns as lun0_flash.bin, lun1_flash.bin, ...
"./edl.py rl dumps --memory=ufs --lun=0 --skip=userdata,vendor_a" -> to dump all partitions from lun0 to directory dumps for device with ufs and skip userdata and vendor_a partition
"./edl.py rl dumps --memory=ufs --genxml" -> to dump all partitions from all lun to directory dumps and write rawprogram[lun].xml
"./edl.py rs 0 15 data.bin --memory=ufs --lun=0" -> to dump 15 sectors from starting sector 0 from lun 0 to file data.bin
"./edl.py r boot_a boot.img --memory=ufs --lun=4" -> to dump the partition "boot_a" from lun 4 to the filename boot.img

"./edl.py wf dump.bin --memory=ufs --lun=0" -> to write the rawimage dump.bin to flash lun 0

Install EDL loaders

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

Run Diag port tools (examples)

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

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

Usage

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

Issues

Secure loader with SDM660 on Xiaomi not yet supported
EFS directory write and file read has to be added

Tested with

Oneplus 3T, Oneplus 6T, BQ X, BQ X5, BQ X2, Gigaset ME Pure, ZTE MF210
