Update QFIL version
QFIL is still in the beta version and has many issues, but it gets frequent updates from time to time. If you try to use an old QFIL version flash with the latest-gen Qualcomm smartphone, it may show a Sahara Fail error on your screen. So the best way is to make sure you’re using the latest version of QFIL software.

USB cable issues
If the USB cable you’re using to flash firmware files to your Qualcomm is of either cheap quality or damaged, then it may create problems in the flashing process. In the worst-case scenario, it can even damage your device or may cause a Sahara Fail Error in QFIL. So make sure to use a good-quality USB transfer cable.
Incompatible programmer file
Each firmware bundle comes with a different set of programmer files intended for use with multiple tools. Tools such as SP flash tool, Img flasher, and QFIL use a different set of instructions to flash programmer files. So make sure to choose the compatible programmer file.
Note: Programmer files compatible with QFIL often have QFIL or Qualcomm in their name. For eg. prog_emmc_qfil_qualcomm_8996_ddr.elf
Issues with File path
File-path is very important when it comes to flashing firmware files using QFIL software. If the file path is not mentioned correctly, the flashing process will not begin or it will terminate automatically giving your Sahara flashing error.
Eg of a bad file path: C:\Users\Rah Ver\Desktop\Flash files\QFIL Qualcomm
Eg of a correct file path: C:\Users\Rah_Ver\Desktop\Flash_files\QFIL Qualcomm
Corrupt Firmware Files
It is important to download the correct firmware files to flash these files successfully onto your device. If the firmware files you downloaded from the internet have integrity issues or are corrupted, then they will show various QFIL errors on the log screen.
Make sure to Download Firmware files for QFIL from official sources. Also, cross-check their “checksum” before flashing them with the QFIL tool.
EDL problems
Putting the device in EDL mode way before the flashing process can lead to Sahara Fail Error in QFIL because of timeout issues. For a good and successful flashing experience, you should put the device in EDL mode right before the flashing process is about to start.
Corrupt Qualcomm driver
Since the QFIL tool is specifically designed to work with Qualcomm smartphones only, you should make sure to download the correct driver for your particular model. Installing the wrong drivers or incompatible drivers will lead to failed flashing and errors.

Disable Driver Signature Enforcement
Driver signature enforcement is a special feature in Windows that prohibits users from installing third-party unverified drivers. This is essential to protect people from any malware or virus attack. However, installing drivers is important for the QFIL tool to work correctly. Here is how you can disable driver signature enforcement in Windows 10.
Open the command prompt in Administrator mode.
Type these commands and press enter
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
Restart your PC and use the QFIL tool normally.
Conclusion
QFIL is just a flashing tool and it can yield Sahara error or other types of error if you don’t handle it with care. I suggest you make sure to use a good-quality transfer cable and correct firmware files. If you do, you will not face Sahara Fail Error in QFIL.
