      @arnaudp I think you've got incomplete file/files - 55498 bytes is too short (incomplete download from https://software.pycom.io/downloads/sequans2.html ?).

      CATM1-39529.dup is almost 6MB big
      updater.elf is over 400KB big

      The machine is working as good as it's code.

        @rskoniec Yup, that's the file I have on my disk, just checked the size with a freshly dowloaded version. It seems that it's the sending that didn't work. And now it says it won't detect the modem (perhaps because of faulty upgrade). Ok not anymore
        But my files are the right ones on the disk :/

          With some debug infos. We can see the files are listed with their right size :

          File /sd/updater.elf has size 429340
File /sd/CATM1-39529.dup has size 6059510

          Here is the complete log :

            @arnaudp One more thing just came to my mind - do you have SIM card inserted in your FiPy? I don't know if this is an issue, but all of my FiPy modem f/w updates I've done with SIM card.

            The machine is working as good as it's code.

              @rskoniec We haven't received our cat-M1 SIM card yet. Do you think I can try with a regular SIM ?
              In this video tutorial : https://core-electronics.com.au/tutorials/pycom-gpy-fipy-cellular-lte-firmware-update.html
              it seems he hasn't put a sim card in it. Weird. Or the video is a bit outdated maybe.

                @arnaudp I've started a forum chat with you. Can we continue there?

                    @Xykon When I was helping @ArnaudP to resolve the problem with FiPy modem f/w update (sqnsupgrade.run('/sd/CATM1-version.dup', '/sd/updater.elf')) from initial release, we went this path:

                    • upgraded FiPy from 1.10.0.b1 to the latest stable 1.18.1.r4
                    • on FiPy 1.18.1.r4 modem f/w upgrade to the newest CATM1-39529 failed
                    • on FiPy 1.18.1.r4 modem f/w upgrade to previousCATM1-38638 failed
                    • downgraded FiPy from 1.18.1.r4 to 1.18.1.r1
                    • on FiPy 1.18.1.r1 modem f/w upgrade to CATM1-38638 successful
                    • now I'm waiting for @ArnaudP feedback about modem f/w upgrade to CATM1-39529 on FiPy 1.18.1.r4
                    • @ArnaudP has confirmed that after previous step, modem f/w upgrade to CATM1-39529 on FiPy 1.18.1.r4 was successful

                    What I've noticed is that updater.elf file in the previous CAT-M1/NB1 releases is the same and with a size of aprox. 300KB, but for the latest they are different for CAT-M1 (420KB) and NB1 (364KB). I've been told by @ArnaudP that he had already sent you a message.

                    The machine is working as good as it's code.

                        I am on the same page with version r4:

                        >>> import os

>>> sd=SD()
>>> os.mount(sd,'/sd')

                        Please advise on how I may be able to downgrade to 1.18.1.r1, so I may be successful....per post below.

                          @dda Download 1.18.1.r1 from here https://software.pycom.io/downloads/FiPy-1.18.1.r1.tar.gz and downgrade using Pycom Firmware Upate tool with flash from local file option.

                            @arnaudp I've been attempting to update the modem from UART no SD card. Haven't been able to do it.

                              @rskoniec Thanks for these detailed instructions. I've followed them and no longer get the Aborting error, however the process seems to fail:
