How did you flash TWRP and custom if your USB port isn't working?
Download Mode is independent of ROM so unless your hardware got damaged since flashing custom, there's no reason it shouldn't work
Try installing Samsung S7 driver again, remove old drivers from device manager first while phone is connected / enabled "Show hidden devices" from device manager while phone is disconnected and remove old drivers
Windows should install the correct driver itself

If you have tried 4 PCs, and different USB cables then you need to get your USB port on the phone replaced / repaired

[SOLVED]GIONEE F205 Stuck in orange state bootloop after unlocking bootloader.

I entered fastboot in my gionee F205 through ADB and entered the command 'fastboot continue' which I got a error FAILED (remote: not support on security).
So I tried to unlock OEM and did the same through fastboot. Now when I reboot my device it is stuck in a bootloop with a message 'orange state your device has been unlocked and can't be trusted your device will boot in 5 seconds'. It reboots again after that 5 secs.I have not yet rooted my devicee. Please help
Edit:
Okay, I solved it. The issue was solved when I removed all unnecessary VCOM drivers from my PC and mainly the MTK USB driver since it was the problem(I suppose). My phone was switching between the preloader driver and MTK USB driver and this was causing SP FLASH TOOLS to think my device disconnected, giving me the error(The flashing is happening only when the PC detects my phone as VCOM PRELOADER driver. So I uninstalled that driver and the problem was solved. I also had to plug my USB in at moment when my phone would be recognized as PRELOADER DRIVER in my pc.
So it is now well and running
Hint: Add Gionee F205 to this thread's title thus mainly owners of such device get addressed.
