      @NoelFlantier , Thank you, but I'm stuck at stage 7.

      Terminal tells me: error: cannot load 'twrp.img': No such file or directory
      I've name my file twrp.img but don't know where to put it so the system will find it...
      Any clue ?

        Thanks for helping, however I'm new to this and I'm not sure to understand all the meaning of this thread.

        I'm using TWRP App (see screen shot) and it looks quite different from what I've seen online
        WHen I open it, it says: "device not rooted"
        Then I still have the same screen as described before (see screenshot 2)

          @Pschit No not that one you need to download the twrp recovery for your device use fastboot to install it then clear cache format partitions. I know that sounds complicated.
          What I would do is read through that thread. You will see where join in and the full explanation is. Take your time, read, then try. I have only done this once and it does appear more complicated than it is. All the links to twrp recovery are in the thread. I'm on mobile so bit awkward to find them just now. Give it a try and just pop back with any questions.

            Hi @NoelFlantier

            I've manage to go through all steps.
            What am I supposed to do after that ?
            Root the phone ? Not sure what/how to do that

            Thx

              Hi @Lakotaubp ,

              I managed to install TWRP recovery but don't understand the next step about clearing cache format partition to ext4...
              I'm stuck there for now, digging,
              any clue is welcome

                @Pschit Reboot to the now TWRP recovery (vol down and power buttons held together). Use the twrp menu options there to fix system and data and cache. Data and cache should be ext4. Not sure exactly where to find them as only done this once. Then rerun the installer.
                The other option was to boot to fastboot then when connected to a pc with fastboot type

                fastboot format :ext4 cache && fastboot format :ext4 data
                But don't think that worked for me but twrp did. All this is about 6/7 Nov in the OP3/3T thread.

                  Success !! Thanks @Lakotaubp and @NoelFlantier

                  Here is a short summary of the actions I made:

                  • On PC: - Install "UBPorts" and "Minimal ADB and Fastboot"
                    - Download TWRP recovery image and put it in "ADB and fastboot" folder (in program files for Windows)

                  • On phone: - Change to developer settings, activate debugging USB and OEM unlock
                    - Download SuperSU zip file from chainfire

                  • On PC: in a terminal enter:

                  fastboot flash recovery twrp.img

                  Then

                  fastboot boot twrp.img

                  • On phone: When on bootloader plug your phone to PC's USB so TWRP Recovery will start
                    Click on Install
                    Look for superSU.zip file on your phone
                    Slide the arrow to the right
                    Phone will reboot at least 2 times

                  • On PC ; use again the fastboot boot twrp.img to restart TWRP
                    *On Phone: Click wipe
                    Then Repair and change format to ext4 for "System" "data" and "cache" folders
                    Then back to wipe menu select the 3 folders and slide the arrow to the right

                  • On PC: Launch UBPorts and install Ubuntu Touch

                  • On Phone: When you reach the Android recovery screen, go to Android data> android actions > Full factory reset

                  • On PC: launch installation again if needed

                  Then your done !

                        @Pschit Congrats on getting this to work. I have been breaking my head on this for sometime . I tried all your steps . After the Android actions-> Full Factory Reset -> Wipe data , it is loads one plus screen and loads to fastboot mode.
                        Also i did small change in your steps i sideloaded supersu.zip through adb and twrp installed directly. Any advice will be helpful.

                          Hi @CAnoop,

                          The only thing I think about regarding your question is that one of your folder has not been properly converted in ext4
                          Make sure you try them 1 by 1 using "Repair" or "Change" functions
                          If you have an error message saying you can't convert, then try using other functions of TWRP, you should be able to convert them all 3.

                          Also, According to what I read in this forum, the "Android actions-> Full Factory Reset -> Wipe data" action is not always necessary.

                          Good luck !
