@Lakotaubp Okay. I solved the problem now.

@doniks excellent point, well spotted. I suppose the correct number is 64 then, not 256 as previously stated by me. Why this is so? Might have something to do with block size. But I haven't done proper research to know for sure. EDIT: Turns out the fdisk man page talks about tracks and sectors. 1 track consisting of 63 sectors by default. Partitions are not allowed to span tracks, i.e. the number if tracks in a partition must be an integer value.

ha-ha, your right, i mixed it up with the oneplus 3T I have. I have the 64 GB, so everything is OK. Slightly wobbly start on this forum, but I will do better

I am also interested in this. Maybe this could be added like a customization of shortcuts... like in a desktop OS - since not all the phones have the same physical buttons.

Oh... It seems I've assumed, that there was some kind of black magic switching channels for me... A compelling case of rtfm (respectively wiki) - I'm sorry...

@mlinodasilva I have not such a problem with sound, but other users reported that already. So yes a bug. You can still install some scopes from Canonical Ubuntu store. Maybe not all, but most yes.

@Sconio look on the xda forum, just Google : xda multirom pro 5 :

Revised command worked .. now installed and working
