Download Fail Sahara Fail error in QFIL
With QFIL, one error You will eventually encounter is the Download Fail: Sahara Fail: QSaharaServer Fail: process fail error.
There are a number of reasons You may get this error so let’s see their Solutions.
Reasons for QFIL Sahara failure and solutions
- Incompatible firmware:- If you are trying to flash the wrong firmware or version of your device you may run into this error.
- using an old QFIL version:- you may run into this error while using an old version of QFIL.try with the latest version.
- using QFIL standalone:- There are two formats of QFIL- one which is co-installed with QPST and QFIL standalone . in case you’re encountering Sahara fail while using the QFIL standalone then install the latest version of QPST and use the QFIL that comes with it.
- Incompatible programmer file:- You Will usually find multiple programmer files (with firehose in the name) in your firmware, in case you do then consider trying the others in the firmware. If not, try With A different Flash File.
- Space in file path:- Check the file path to your firmware and ensure there’s no space in any of the directory names Example: C:\Users\Hovatek\Desktop\Hovatek_files\QFIL_Qualcomm instead of
C:\Users\Hovatek\Desktop\Hovatek files\QFIL Qualcomm
- Entering EDL Mode too early:- Entering and leaving the device in EDL mode for too long before flash should cause a Sahara error due to timeout. putting the device into EDL mode should be the last thing you do just before clicking download (which initiates flashing)
