after flashing device, all qfst tool worked finely. i can backup and restore file from my device. after get OTA update, all that tool give me sahara failed response. all driver work fine, but port diag status is " no phone" detected when i open QPSTconfig. what can i do to fix this??? i need to make backup new firmware, because i don't find infinix s3x x622 stock rom firmware with this version.
when i used old version boot.img in magisk root tool, my device get bootloop, after factory reset, it stuck in infinix logo. any idea for root with magisk???

Thanks for your response, EDL mode is fixed with smartuninstaller, remove all qualcom driver and registry than re install the qualcom driver. But i still have problem with port DIAG. when connected, Port detected, but No Phone, so i cannot backup/restore qcn file.

try to manual update the driver as detected in device manager to "qualcomm hs-usb android diag 901D", if successful then retry connecting to qpst
btw how did you enable diag mode on the phone?

you've already installed the qualccomm driver exe
goto device manager > diag driver > update > browse my computer for driver software > let me pick from a list of ... > show all devices > untick the checkbox beside compatible hardware > select 901D and complete the installation

You don't seem to be in EDL Mode. How are you entering EDL?
