QFIL Flashing Error: Download Fail: Sahara Fail: QSaharaServer Fail - Reasons and Solutions

What is sahara_download() and why it may cause an io error

If you have ever tried to flash a Qualcomm-based Android device, you may have encountered a tool called QFIL (Qualcomm Flash Image Loader). QFIL is a free software that allows you to flash stock or custom firmware on devices with Qualcomm chipsets.

One of the steps involved in flashing with QFIL is sending the programmer file to the device. The programmer file is a binary file that contains the instructions for the device to enter download mode and receive the firmware. The programmer file usually has firehose in its name, and it is specific to each device model and variant.

To send the programmer file, QFIL uses a function called sahara_download(). This function communicates with the device in EDL (Emergency Download Mode), which is a special mode that allows flashing devices with Qualcomm chipsets. EDL mode can be entered by using a special cable, a key combination, or a software command.

However, sometimes sahara_download() may fail and cause an io error. An io error is an input/output error that occurs when there is a problem with reading or writing data. An io error can prevent QFIL from flashing the device successfully, and it can be very frustrating to deal with.

In this article, we will explore some of the possible causes and solutions for sahara_download() io error. We will also provide some tips on how to avoid this error in the future.

How to solve the problem of "saharadownload() -ioerror" in qfil?

Incompatible firmware

One of the main reasons for sahara_download() io error is using a wrong firmware or variant of the device. For example, if you have a Samsung Galaxy S10 with model number SM-G973U, you cannot use a firmware for SM-G973F or SM-G973W. The firmware must match your device model and variant exactly, otherwise it will not work.

To find out your device model and variant, you can check the label on the back of your device, or go to Settings > About phone > Model number. You can also use a tool like CPU-Z or Device Info HW to get more information about your device.

Old QFIL version

Another possible cause of sahara_download() io error is using an outdated version of QFIL. QFIL is constantly updated to support new devices and fix bugs, so it is important to use the latest version available. Using an old version of QFIL may not be compatible with your device or firmware, and it may cause errors.

To check your QFIL version, you can go to Help > About in QFIL. To download the latest version of QFIL, you can visit the official website of Qualcomm Product Support Tools (QPST), which is a package that includes QFIL and other tools for Qualcomm devices.

Incompatible programmer file

A third possible cause of sahara_download() io error is using a wrong or corrupted programmer file. As mentioned earlier, the programmer file is a binary file that contains the instructions for the device to enter download mode and receive the firmware. The programmer file usually has firehose in its name, and it is specific to each device model and variant.

If you use a wrong programmer file, QFIL will not be able to communicate with your device properly, and it will cause an error. If you use a corrupted programmer file, QFIL will not be able to read or write data correctly, and it will cause an error.

To find the right programmer file for your device, you need to look inside the firmware folder that you downloaded for your device. The programmer file should be there, usually with firehose in its name. You can also search online for your device model and variant, and download the official or compatible programmer file from a trusted source.

Space in file path

A fourth possible cause of sahara_download() io error is having a space in the file path to the firmware. For example, if you have your firmware folder in C:\Users\John Smith\Downloads\Firmware, QFIL may not be able to access it properly because of the space between John and Smith. This can cause an error when QFIL tries to send the programmer file to your device.

To avoid this problem, you need to remove any space in the file path before flashing. You can do this by renaming or moving your firmware folder to a location without any space in the file path. For example, you can move it to C:\Firmware or C:\Users\JohnSmith\Downloads\Firmware.

Entering EDL too early or too late

A fifth possible cause of sahara_download() io error is entering or leaving EDL mode for too long or too short. As mentioned earlier, EDL mode is a special mode that allows flashing devices and programmer file for your device. As mentioned earlier, one of the main reasons for sahara_download() io error is using a wrong firmware or variant of the device. The firmware and programmer file must match your device model and variant exactly, otherwise they will not work.

To find the right firmware and programmer file for your device, you need to look inside the firmware folder that you downloaded for your device. The programmer file should be there, usually with firehose in its name. You can also search online for your device model and variant, and download the official or compatible firmware and programmer file from a trusted source.

Remove any space in file path

A seventh possible solution is to remove any space in the file path before flashing. As mentioned earlier, having a space in the file path to the firmware can cause sahara_download() io error. QFIL may not be able to access the firmware folder properly because of the space in the file path.

To avoid this problem, you need to rename or move your firmware folder to a location without any space in the file path. For example, you can move it to C:\Firmware or C:\Users\JohnSmith\Downloads\Firmware.

Enter EDL at the right time

An eighth possible solution is to enter EDL mode at the right time before flashing. As mentioned earlier, entering EDL mode at the wrong time can cause sahara_download() io error. QFIL may not detect your device or lose connection with your device if you enter EDL mode too early or too late.

To avoid this problem, you need to enter EDL mode at the right time before flashing. You can follow the steps mentioned earlier in this article, or refer to the instructions provided by your firmware source or device manufacturer.

Conclusion

Sahara_download() io error is a common error that occurs when flashing Qualcomm-based Android devices with QFIL. It can be caused by various factors, such as incompatible firmware, old QFIL version, incompatible programmer file, space in file path, or entering EDL mode at the wrong time.

Fortunately, there are many solutions that can fix sahara_download() io error, such as restarting your computer, checking your cables and connections, trying an alternative USB port, running CHKDSK and SFC, using the latest QFIL version and QPST package, using the correct firmware and programmer file, removing any space in file path, or entering EDL mode at the right time.

By following these solutions, you should be able to flash your device successfully and avoid sahara_download() io error in the future. However, if none of these solutions work for you, you may need to contact your device manufacturer or a professional service center for further assistance.
