      @moem you can just boot back to twrp and you need to look under advanced wipe otptions. Clear format to ext4 cache and data. Then try again. You might need to do system as well.

          Okay, I managed to do this. But I'm still getting the same error:
          Installing - connection to device lost

          And it also pops up a notification about not being able to mount something. Here's an example, but the numbers differ a bit:

            The installer offered to reinstall OxygenOS, and that worked! So at least the thing boots again. More experiments to follow soon.

                @lakotaubp I don't see anything relevant in that thread... maybe I'm missing something?

                    @lakotaubp Ah, THAT fifth of November! Will check, thank you.

                    Edit: I see a lot of mentions of using TWRP for wiping cache/data/system partitions... which I have done at least five times today in different ways. 😕
                    No success yet.

                      @moem Just found this
                      libremax Just trying to think what I did with twrp. Wipe option, format data-select yes, then in advanced wipe repair change system and data to ext4 then reboot. Then just ran the installer with wipe and bootstrap, booted to fastboot then recovery for the rest. I do remember it took ages for the spinning circles to appear to say it was flashing the device. Remember thinking it had not worked at first. Maybe leave it a little longer rather than force reboot but bit confused I must admit.

                      But that's about all. Will keep looking

                        I know about the wipe, but what is the bootstrap?
                        It does not take long at all to tell me it's flashing. It always fails during the 'pushing files to the device' phase. And I never try to reboot at all... there is, after all, nothing to reboot.

                        Thank you for your time!

                          @moem It was an option given in the installer is it not there now? Also found this from Flohack

                          @sven Also delete system partition to be sure 😉 - If there was encryption used for data before, it needs to be formatted, a simple wipe wont work.

                          Might not help but explains why.

                            I see two options: First Install (tick if the device was running Android before) and Wipe Data. Dalton advised me to tick them both.

                            I've wiped all the things.... so many times. And done a factory reset, and reinstalled Oxygen. All partitions show up as Ext4.
                            I don't by now even remember what I've tried. 😕

                              @moem Sounds like time for a break and come back fresh. Packing in for today soon myself . Good luck and will keep thinking.

                                You are most likely right. Thank you, again, for your time!

                                  @moem I found that it is better to tick "First Install" regardless, then the installer guides you through what you need to do in TWRP recovery to prep the partitions, I also found that if you untick "Wipe Data" the install completes to 100%, otherwise I get the connection lost dialog at around 75% if I tick "Wipe Data".

                                  I can 100% complete the install every time now but my device freezes on the 2nd reboot after install.

                                  I am using UBports installer version 0.8.6 beta on Endeavour OS. It might help if anyone has success to let everyone know which installer version they are using and on what OS.

                                  I am thinking of getting access to a Windows machine to see if it makes a difference, I have tried different usb cables in both front and rear USB ports.
