[SOLVED] Impossible USB tethering (standard, not reverse) connection

jumpy88

No question is stupid when debugging
I haven't tried (I will) but the one I'm using is the same I used to install UBports UT, and I had no problem.

@jumpy88 can you check these steps https://bugs.launchpad.net/ubuntu/+source/dbus-property-service/+bug/1427697/comments/8?

Ok, for completeness I've tried another cable and I'm experiencing the same issue. Moreover, both of them work fine for MTP.

@advocatux ok, I think we are done. In the previous OS version I had on my phone

android-gadget-service enable rndis

was enough. Reading the guide you posted I found out there is a

sudo tethering enable

to be executed. I tried and now this post is flowing through my BQ E4.5
Now I have just two more questions: before to see the command I had already enabled RW permissions on my device. Is there a way to go back to RO without reinstalling the OS or is it impossible as described here? Should I be scared of having a RW OS or is it ok?
Thank you for the support up to here.

@jumpy88 you're welcome. The easier way to switch from ro and rw and vice versa is using UT Tweak tool

@advocatux ok, thank you, I'll have a look in that. For now I think it's enough today

Just to summarize:

no need any OS modification
no need developer mode enabled
just run on phone terminal:

android-gadget-service enable rndis
sudo tethering enable

ps Would it be difficult to integrate this with the network menu? It's a pretty common feature to require.

I understand this correctly? You are trying to use your phone's internet connection as your desktop internet connection via USB cable?
And you were able to make it work?
because I filed this bug long time ago after the xenial switch because it stopped working. In vivd, switching in the UT tweak tool was enough.
Do you mean ```
sudo tethering enable

jumpy88

Hello @kugiigi, yes you understand correctly. I guess UT tweak tool just calls

android-gadget-service enable rndis

because I have tried it and I see the same behaviour. After that you have to call

sudo tethering enable

and it should work. Remember to do both, not just the second one, and it is necessary each time you switch to MTP.

@jumpy88 oh I see, that's good news then.
I will try it on my phones and see.
If we can confirm this, then we can add this information in the bug and maybe close it.
And add a bug in UTTT

@kugiigi already added in the bug report 6 minutes before your last post

@mito77 If you use UTTweakTool and go to system ADB Settings it will tell you if MTP is on. By the way did you notice how old this thread is.
