Bricked Swift

Try to access the bootloader with the hardware button combo first (volume down + power / volume up + power). If you get into recovery, you will be able to get to the bootloader with adb or a menu entry. Depends on what recovery you have installed for the latter.

In case you have no access to the bootloader (proper soft brick), go for the QFIL method. Avoid using it unless there is no other option.
Here is the thread:

Cant access bootloader.
However, tried your second option and it went well until i got "SaharaDownload fail" at the last step, and now my computer doesnt recognize the phone in device manager. It does not show anywhere that my phone is connected.

Does the phone give any indication of being connected? Notification light, starting the display, etc?

If yes, make sure the phone is in the correct mode and check the drivers - some of the other forum members mentioned this and the gymnastics around the battery. This would be on my to-do list. The device might come up on the device manager as different one, so monitor the manager for any changes once you connect the device.

If you happen to have Windows 7 device laying at you house, you can try with it (if only not to worry about compatibility and sporadic Win10 behaviour).
It will be a good idea to check the turkish website for General Mobile 4G (one of the Android one derivatives of the hardware) where some people have faced similar problems using the same tool.

Finally got my phone back on the device manager! However, I still get sahara error when trying the back to false method.
