      @Fizz Ok, Linux, a bit more. I tend to run from the Command line in the Platform-Tools folder... However, install ADB and fastboot in the CLI. You have to use Chrome Browser (not any other inc. Chromium) to run the Android recovery tool.

      The recovery tool won't see your phone as it needs ADB and fastboot installed.

      What flavour of Linux are you running?

        I am running Linux Mint 20.3.

        OK, so i'll install both fastboot and ADB via the command line first. Then i'll try Vivaldi and Brave again, and failing those, install Chrome.

        sudo apt install fastboot
        sudo apt install adb
        

        Looks like i already had adb installed, just not Fastboot.

          @Fizz If you unzip the factory image PQ3B.190801.002 to the platform tools folder, then run the flash-all.sh from there you won't need to use Chrome and the Android recovery tool (it only works on Chrome, tried it on others it won't work).

            OK, so i have downloaded platform-tools and unzipped it into its own folder.

            I have also installed fastboot via the command line, and adb was already installed.

            So now i'm moved the factory image to the platform-tools folder. So my platform-tools directory contains the following:

            bootloader-sargo-bootloader-sargo-b4s4-0.1-5653622.img
            flash-all.sh
            flash-all.bat
            flash-base-sh
            image-sargo-pq3b.190801.002.zip
            radio-sargo-g670-00011-190411-b-5457439.img

            Also there is the lib64 folder, files adb, fastboot, and all the others that came with platform-tools.

            My phone is connected via usb, it's in Fastboot Mode.

            Do i first need to unlock with fastboot oem unlock? Or do i go straight to flash-all.sh ?

            Sorry if i'm being annoying with excessive questions. I want to be sure i understand things completely, as I've not done this before and i don't want a brick. 😉

              @Fizz Unlock the bootloader first (try fastboot oem unlock).

              Reboot to Android, set it up again when you have done that, reboot to fastboot mode.

              When in fastboot mode run the flash-all.sh command.

              Let it run, when it finishes the phone will reboot.

              Set Android up on the phone again (again) and enable developer options and USB debugging.

              Then run the UT installer and follow the onscreen instructions.

                  @Fizz You won't brick it, I haven't had an unrecoverable brick yet.

                  If your Pixel 3a hangs at the Google logo see my previous mentioned thread.

                  Be patient, UT takes time to install.

                    Well, the first step went well, i was able to unlock the bootloader. Note the exact command was actually "fastboot flashing unlock".

                    I let Android reboot, went through the basic setup, etc. Once that was done i rebooted to Fastboot Mode.

                    But I just tried to run flash-all, and my laptop tells me the command is not found. I've tried "flash-all.sh" as well as "flash-all", but neither is recognized. The file is right there in the current folder. What've i done wrong?

                      @Fizz Try sudo flash-all.sh. I am not on my Linux system so I cannot remember the exact command. If sudo soesn't work try sh flash-all.sh or ./flash-all.sh.

                        Hmmm.... the latter two suggestions work- it executes. But now it tells me:
                        fastboot too old; please download the latest version at https://developer.android.com/studio/releases/platform-tools.html

                        But that link just redirects to the same file that i downloaded and unzipped earlier.

                        Hrmmm... so not sure what i need to do here...

                          @Fizz On your laptop, you are in the platform tools folder and you have the unzipped Android ROM - factory image PQ3B.190801.002 - in there too? You have opened a command prompt in that folder as well?

                            Yes, i created a folder named platform-tools, which has the contents from android's site (https://developer.android.com/tools/releases/platform-tools ).

                            In that same folder i have moved the contents of the image download ( from https://developers.google.com/android/images#sargo ).

                            So the contents of the folder are:

                            lib (folder)
                            adb
                            etc1tool
                            fastboot
                            hpor-conv
                            mak_f2fs
                            mak_f2fs_casefold
                            mke2fs
                            mke2fsconf
                            NOTICE.txt
                            source.properties
                            sqlite3
                            bootloader-sargo-bootloader-sargo-b4s4-0.1-5653622.img
                            flash-all.sh
                            flash-all.bat
                            flash-base-sh
                            image-sargo-pq3b.190801.002.zip
                            radio-sargo-g670-00011-190411-b-5457439.img

                            I know there is still a .zip file in that folder, but from what i read that should be left alone- not unzipped.

                            In the terminal, i am in that same directory, platform-tools, where all the files are.

                              @Fizz Odd it should work? Maybe someone more advanced on Linux could chip in?

                              I downgraded generally with chrome and the android tool on Windows 11(😠 😠 Yes I know), it has worked for me.

                                Well, what i'll try next is installing Chrome on my laptop, and seeing if the flashing will work through the flash tool. Will let you know how it goes.

                                  Well, the Chrome method seems to be working- it has recognized the device and i've pointed it to the correct build.

                                  Quick question- the flasher is asking me:
                                  You are downgrading your bootloader, which normally means you are flashing an older build. This usually requires a factory reset to successfully boot the device.
                                  Would you like to factory reset your device?

                                  Do i want to do this? I've no data on the device i care about.

                                      Well, things aren't going well so far. It does the download of the desired image. But i run into problems shortly after the install attempt.

                                      When it starts the install, it says Rebooting Device into Bootloader. The phone screen flashes briefly, but comes back to the Fastbook Mode screen almost immediately.

                                      A few seconds later, the installer says
                                      Flash Failed
                                      Timed out waiting for device to disconnect

                                      It gives me the option to "retry", but it never works. The only way i can really start it again is to close Chrome (per the instructions the installer gives), re-open it and try again. In that case, it does a full download of the image again. And unfortunately this pattern just repeats.

                                      I'm on my third attempt now, downloading the image again. The install definitely did something, as the phone won't boot Android at all anymore- i can only get it to Fastboot Mode. But it's not getting far with the install either. Ugh.

                                      UPDATE- well third time it made it a lot farther. It got through few stages of writing the image, and appeared to be loading Android (white page with Google logo), but then i again got the Flash Failed Timed out waiting for device to disconnect error.

                                        Being that i am stuck at the Google splash screen, i am looking at your earlier link. Do you mean i should now try the UT installer- that the old version of Android is now sufficiently installed that i can try installing UT?

                                            @Fizz No, it looks like the required version of Android has failed to install for whatever reason on your hardware.

                                            Take a step back and don't try and batter on through it as it won't work.

                                            In the platform-tools folder open a command prompt.
                                            Ensure the phone is in fastboot mode and connect to PC
                                            In the command prompt run the command fastboot devices
                                            It will pick the device up and show its serial number
                                            If it doesn't, reboot the device to fastboot and try again
                                            If it is still not picked up, then try another USB cable on a different port.
                                            If it does get picked up, good.

                                            Then you can either try the flash-all.sh in the platform tools folder or rerun the android recovery tool in chrome. If it disconnects in the middle of it there will be something on the laptop interfering. If it does, unplug the phone and reconnect it and see if it continues.

                                            This is what my platform tools folder looks like in windows, Linux will use the same (I use Ubuntu).

                                            Right click and open your terminal in this folder and run your fastboot and flash-all.sh from here.

                                            You must allow the device to boot fully into Android and ensure that
                                            a) you are on the correct ROM
                                            b) your bootloader is unlocked
                                            c)developer options are enabled so you can enable USB debugging.

                                            This is why I have a Windows system (ugh), my Ubuntu system and a mac too hand. If I cannot get it working on one, I will on another (and I have to use Windows as where I work, most people don't know Linux exists, even though they use it on one system).

                                            Xiaomi Redmi Note 7.... And more...
                                            I have too many devices...
