yes, true. But then, what they do looks quite straightforward. They have one partition on the sdcard that contains a readable configuration file giving the names and kernel image paths of the installed OSs on the card and the kernels and init-rds of the multiboot OSs. And then each installed OS has a (read only) system partition (I guess more or less what would be flashed to the device normally) and a writable data partiton for each OS.

So it looks like one could replace the kernel image and the read-only root partition files and you would be done. Does anyone know of such a root-partition image (or tar file or whatever) with a Ubuntu-Touch 20.04 (Focal) system for a Volla 22 phone that I could download?

But, yes, would probably make sense to ask in the volla forum as well.

Hi all,
I currently have 3 operating systems on my volla 22 phone. VollaOS installed internally and SailfishOS and Ubuntu-Touch as multiboot on an sd card. Works great, so far.

Now I would like to upgrade my Ubuntu-Touch which currently is a Xenial (16.04) to Focal (20.04). Does anyone have some pointers, how I can do that when the OS is installed on sd card (as opposed to the internal storage). The instructions I have found so far all assume that the OS is installed on the internal storage. And I don't want to damage the VollaOS that is installed there on my phone.

I would actually be quite happy with instructions how I could update / install Focal on the sd card while it is inserted in my (Linux) PC. That way, I could be 100% shure to not damage anything on the phone.

I've actually already successfully set up a second sd card and copied Sailfish and UT over to that completely on the pc. So I have a spare card for experiments.

Is there some UT-Focal image somewhere, that I can just copy into the UT root partition on the sd card completely from the pc? Has anyone ever done something like that?

@matteo Good idea to integrate it into the OS. But even in the current state, the app is very useful. Thanks a lot!

Hi @Keneda,
Thanks a lot for the hint! I just installed "datamonitor" and it looks promising. I'll try it.

Hi all,
I am new to UT (and to this forum), so please excuse, if I should be asking a stupid question (or violate some forum nettiquette).

I am inklined to use UT as the primary OS on my phone, but I am missing an important feature (for me, at least) and could not find much information on the net so far:

Is there a counter for network traffic? Especially for traffic via the mobile network? I have a limited amount of network data in my mobile contract, so I would like to keep track of the amount I have used up already. Preferably something that I can reset to 0 at an arbitrary point in time (as my data limit is renewed every 4 weeks not aligned to calendar months).

The only thing I was able to find was this old thread: bandwidth counter for mobile data connection that talks about installing some CLI program for that purpose.

Is there something a little more convenient in the meantime?
