Funky issue: device needs to have flashed halium-boot once; afterwards hybris-boot works as usual Current status: LXC runs; now to actually get tests to run

When i build with CONFIG_PID_NS enabled, i get the following build error on mka hybris-boot (and systemimage):

Plasma boots :) Still have lots of errors in dmesg and logcat to deal with though, and scaling seems woefully incorrect.

Hi,

I have the LTE version. i9195.

I would be interested to get Ubuntu touch running.

I have a few spare serranoltexx(i9195) boards, it shouldnt be that hard to port it since it already boots on the duos. Most likely changing the kernel and some modem stuff.

[rogieroudshoorn]

Since all s4 mini's share a common lineage kernel & device it should be as easy as replacing 4 defconfig flags to get it booting on the LTE version; i think the 3G version will "just work" with what there is.

I am nowhere near getting the modem to work anyway, and if you guys want to pitch in on the 9195, i think we'll go a lot quicker. Warning though - the kernel is so old on this device, the newer versions of plasma will probably not work (they'll require a newer kernel for systemd). UBPorts will probably be fine until they jump to 20.04.

in a few weeks i will get parts for one of my 9195s and il be happy to test it

Any activity still here? Modem does not work because Samsung uses an incompatible RIL layer that will not work with ofonod out of the box. I fixed this for S3, and probably same stuff needs to be done for other Samsungs...

[rogieroudshoorn]

Not really, ordered a pinephone so i'd have something that is usefull for a much longer term ... still have the phone laying around somewhere if there's something you'd like to me test though!

Well interesting question first, can you look in your device tree if there is a RIL.java class to be found (* means something could be written before or after the word RIL). You might want to search in the original tree since Halium tends to strip out those files.
