        So, I wanted to modify the file /system/usr/keylayout/gpio-keys.kl but the file system is readonly.

        You would have to do this from recovery, as it's modifying the Android side.

        I don't know if it will work, but if it does then your volume buttons will not be usable for volume any longer.

          Hi, thank you for your fast reply.

          Can you explain a bit what you mean by "from recovery".
          I am ready to try anything, am i not using the right tools ?

          I understand what it implies but I think I can live without volume buttons as I can change the volume inside the settings pannel. Unfortunately, a phone without a power button is almost not usable. When the screen is locked, the only way to wake it right now is to plug a USB cable and then unplug it to unlock the screen. :beaming_face_with_smiling_eyes:

            @creuzdos You can also use a magnetic case or any magnet šŸ˜‰

              adb reboot-recovery

              You will need to adb shell in recovery mode, to make any changes to the Android image parts, such as gpio-keys file.

                @kugiigi Wow... I didn't know this trick could work... this could be a solution indeed. Unfortunately, I have none to try it now but this is very interesting.

                @dobey Ok thanks, i'm not very comfortable but I'll try my best. I think you provided a great help putting me on a good track.

                note : it's adb reboot recovery according to the man page šŸ˜‰

                  @dobey In recovery mode, the /system directory contains only a lost+found directory and i can't find the file /system/usr/keylayout/gpio-keys.kl

                  I tried this : https://nattster.wordpress.com/2015/09/22/use-volume-button-to-wake-up-nexus-5/

                  but at step 6 as i just said... the file doesn't exist. I'm a bit stuck here.

                      It can be repaired, but I would hardly use the word simply to describe the act.

                        @creuzdos I think you need to mount /system first, as it's not mounted yet in recovery, IIRC.

                        Beyond that, I'm not sure.

                              @keneda Even as a hardware geek, it is still quite difficult. It is a very tiny button which must be placed just right, and requires liquid solder paste and hot air rework station to do correctly. It's not a simple solder job.

                                I know i can do it, i already did that kind of solder work.

                                It's just a proposal if he feels he can do it (and have tools for that), or know someone that can do it for him.

                                  @keneda Thank you very much. If you want the full story :
                                  I bought 2 replacement buttons on the internet. I tried to do it myself first... it was a total disaster šŸ˜‚ Then I brought it to a local repair shop. It cost me 35€. And it worked 2-3 months and broke again...
                                  So now I just want to have a usable phone to play with UT. šŸ˜‰

                                  @dobey Ok, I managed to flash my Nexus with an android rom. I could edit the files and it worked perfectly as expected. Then I reinstalled Ubuntu touch. I did not check the "wipe system" checkbox hoping the /system files would stay but unfortunately they have been replaced. I'm trying again tomorrow.
                                  Thank you and good night

                                    Ok i understand :disappointed_face:

                                    However, i must tell, never again go to those so-called "phone repair shops" that pop up from here and there, they're 99% owned by incompetents, always go to real electronician repair shop (hard to find i know).

                                    Hope you will succeed in software workaround.

                                      Here is a little update.
                                      Day 3 : I have installed multiple times android, paranoid android and ubuntu touch
                                      I have used twrp recovery img and modified /system/usr/keylayout/gpio-keys.kl
                                      as I said yesterday it works absolutely as expected on paranoid android but everytime I come back to ubuntu-touch (even when I uncheck every checkbox inside the ubport-installer )
                                      the file /system/usr/keylayout/gpio-keys.kl is the default read-only file.

                                      If anyone has a tip to help me set the /system partition writable or replace this file one way or another. If it is not possible, what i'm going to do next is probably go try paranoid android to play with in the next few days / weeks.

                                      Is it possible to get a zip with the ubuntu touch ROM for NEXUS 5, so i can install it through twrp like i did with the other android systems ?

                                      Thank you all for your help and keep up the good work.

                                        @creuzdos I may be wrong but couldn't you boot into TWRP, use

                                        adb push path/to/new/file /sdcard
                                        

                                        from your host to get the new file on the device and then use the file manager under advanced in TWRP to replace the one that keeps being over written with the one you placed in /sdcard?

                                          Go to \system with file manager, after image made writable with UTTT, then check infos for folders and files in here : all is read only, you will not be able to paste anything here, you can copy files from, then paste in writable folder like "downloads", but that's all.

                                              Go to \system with file manager, after image made writable with UTTT, then check infos for folders and files in here : all is read only, you will not be able to paste anything here, you can copy files from, then paste in writable folder like "downloads", but that's all.

                                              That I why I gave instructions for doing it via the file manager in TWRP. Because in TWRP everything can be written over.
