Yep!
I can mistaken, maybe order should be different.
I've just messed up with those commands and suddenly it worked.

@slowcyclist Thank You very much!

I've just copied and pasted some of lines from your topic and USB-tethering WORKS NOW!!!
(I don't know why )
Here are that commands:
$ sudo android-gadget-service enable rndis
$ sudo bash /android/system/halium/usr/share/usbinit/setupusb reset
$ sudo bash /android/system/halium/usr/share/usbinit/setupusb rndis
$ sudo ifconfig rndis0 up
$ sudo tethering enable

Please, test it sombody else with Oneplus3.

Thank You all!
I was confused by the fact that someone said that he had this feature on Oneplus 3.
So...
I hope we will have this in nearest future.
Have a nice day!

@commisde Hey!
If I'm not mistaken there is no problem with USB-tethering on Nexus 4.
You should just type those two commands in terminal:

$ android-gadget-service enable rndis
$ sudo tethering enable

@gischpelino Your idea sounds good.
Thank you for clarifying the question.

@Lakotaubp No results with UT Tweak Tool.
Is it common issue?
Has anybody USB-tethering working on OP3?

Hello!
I have a issue with usb-tethering.
When I type in terminal
$ android-gadget-service enable rndis
rndis enabled
$ sudo tethering enable
Device "rndis0" does not exist.
Error: Connection 'tetherning' does not exist.

I have had this problem for a long time. I installed the new version several times, but to no avail.
This feature worked fine on Android, but does not work on UBports.

Does anyone have any idea where to look for the cause of the fault?
Thanks in advance.

@peat_psuwit Hi!
About video recording on OnePlus 3.
When I press the record button everything freezes, and there are no errors in the terminal.
Last line in the terminal:
[PERFORMNCE]: Last frame took 60 ms to render
Here are a couple of screenshots:

I hope this will be usefull... somehow
P.S.: Great work. Thanks a lot.
P.P.S.: Does IOS werx... somehow?

@peat_psuwit Thanks! I've reinstalled UT and camera works now.
But video recording still doesn't work.
Where where should I provide debug information if you need it?
