      Hi guys,

      We bought a bunch of FiPy's ... and one one of them, had the same issue.

      lte.reset()
lte.disconnect()
lte.dettach()

      Do the PyCom-thingie (detach Lipo batter, unplugg usb ... ergo HARD Reset, not soft or button ...)

      pycom.lte_modem_en_on_boot(0)

      Last but not least, comes the little-bit-unsure ... as I trued 1st

      sqnsupgrade.run('upgdiff_33080-to-40343.dup', 'updater.elf', debug=True)

      as it's a new board we are updating all the firmware on

      but that didn't work, so I just ran

      sqnsupgrade.run('NB1-40343.dup', debug=True)

      I'm going out on a limb, and guessing, that maybe in the factory when they test all the boards before shipping ... somehow ... maybe it happened that they forgot to "reset", "discennect" and "dettach" it from the LTE Base station ... and the modem thinks it's still in use ... ergo, the updater won't work ... as it modem is "enabled" ...

        sqnsupgrade.run('upgdiff_33080-to-40343.dup', 'updater.elf', debug=True)

        Diff's dont need the updater.elf param so its just

        sqnsupgrade.run('upgdiff_33080-to-40343.dup', debug=True)

        The full upgrade does how ever need it:

        sqnsupgrade.run('NB1-40343.dup', 'updater.elf', debug=True)

        Ill ask someone more qualified than me to look into this as the process @ktleh took should have worked.

        >>> from machine import SD
>>> sd = SD()
>>> os.mount(sd, '/sd')
>>> os.listdir('/sd')
['CATM1-38638.dup', 'updater.elf']
>>> import sqnsupgrade
>>> sqnsupgrade.run('/sd/CATM1-38638.dup', '/sd/updater.elf')

        should have run just fine.

          Hmmm, says the opposite on your docu - https://docs.pycom.io/tutorials/lte/firmware.html ...

          Important: When upgrading your modem for the first time, even if you have updated it in the past with the old firmware update method, you MUST use the "recovery" upgrade method described below. Otherwise you will risk breaking your module.

          Please also use the file upgdiff_33080-to-39529.dup (1.2M) from the archive.

          import sqnsupgrade
sqnsupgrade.run('upgdiff_33080-to-39529.dup', 'updater.elf')

          and then it says, you must run it a 2nd time ...

          sqnsupgrade.run('NB1-40343.dup', debug=True)

          ... and this is the the 1st time you ever update the modem firmware ...

              Hi guys,
              I tried to update the modem firmware of my GPy, but failed.

              First I updated the firmware of the GPy with the Pycom Firmware Update Tool to version 1.18.1.r7.

              Then I followed the instructions in the documentation for the update via UART Serial Interface. I downloaded the file CATM1-39529.zip and uploaded the file updater.elf via FileZilla into the Flash of the GPy. I got an error message that the connection was interrupted by a timeout, but it seemed as if the file was successfully transferred. The file sizes matched.

              Then I started the update process on the Gpy

              >>> import sqnsupgrade
>>> sqnsupgrade.uart(True,'/flash/updater.elf')

              After the message

              Going into MIRROR mode... please close this terminal to resume the upgrade via UART

              I started the update process on my computer:

               >>> import sqnsupgrade
 >>> sqnsupgrade.run('COM9', 'CATM1-39529.dup')
<<< Welcome to the SQN3330 firmware updater >>>
Attempting AT wakeup...

              I got a timeout error after about 5 minutes.

              After a hardreset of the GPy I restarted the update process on the GPy and got the following message:

              >>> import sqnsupgrade
>>> sqnsupgrade.uart(True, '/flash/updater.elf')
<<< Welcome to the SQN3330 firmware updater [1.2.1] >>>
>>> GPy with firmware version 1.18.1.r7
Could not detect your modem!
Please try to power off your device and restart in safeboot mode.

              Currently, the LTE module can no longer be reached.

              >>> from network import LTE
>>> lte = LTE()

              The command hangs. SIM card is inserted.

              In the forum I read already that the command

              pycom.lte_modem_en_on_boot(0)

              could help, but still the modem cannot be addressed.

              Can you help me?

                @florianrdt What does

                import sqnsupgrade
sqnsupgrade.info()

                return to you?

                  @bqpd On the GPy it does

                  >>> import sqnsupgrade
>>> sqnsupgrade.info()
<<< Welcome to the SQN3330 firmware updater [1.2.1] >>>
>>> GPy with firmware version 1.18.1.r7
Cannot determine modem state!

                  The command took some while.

                    @florianrdt Hmm, I think the sqnupgrade.info() method also tries to create an instance of "LTE" and is also failing.
                    Sorry I can't really help you. I hope your Sequans modem isn't bricked.
                    Maybe the developer team has some better insights and can help you. As @Paul-Thornton said, they are looking into the whole modem firmware upgrade process in the near future.

                        did you try to reset the modem?

                        lte.reset()
lte.disconnect()
lte.dettach()

                        I had the same issues ... and it's because the modem has been turned / power off in "active" state ... and it remembers that as it saves it state to it's internal memory ...

                          @combaindeft Wait, so DID your upgrade of the sequans modem on the FiPy (where it failed in the first place) succeed AFTER you did:

                          lte.reset()
lte.disconnect()
lte.dettach()

                          or did i misunderstand you and it is still not working?
                          Sadly i have no SIM-card at the moment so i can't test it myself for the next few days.
                          Did it actually work in the end just doing sqnsupgrade.run('NB1-40343.dup', debug=True) even without using the update.elf file after you did the lte.reset()?

                          but that didn't work, so I just ran

                          sqnsupgrade.run('NB1-40343.dup', debug=True)

                            @combaindeft I can't try this because I can't initialize the LTE object. The comand freeze.

                              Affirmative! ...

                              I couldn't get it to update the modem firmware ... and I read somewhere, that the update firmware function won't work if the modem is in "active mode" ... ergo I tired to Reset, disconnect and dettach it ... and followed by a reboot (I did a reboot, just to make sure...) ... I could update the firmware of the modem.

                              or did i misunderstand you and it is still not working?

                              No, It is working superfine now :-)

                              sqnsupgrade.run('NB1-40343.dup', debug=True)

                              Step 1)

                              lte.reset()
lte.disconnect()
lte.dettach()

                              Step 2)
                              reboot the device.

                              Step 3a) identify if this is the ABSOLUTE 1ST TIME that you are updating the modem firmware

                              sqnsupgrade.run('upgdiff_33080-to-40343.dup', 'updater.elf', debug=True)
time.sleep(5)
sqnsupgrade.run('NB1-40343.dup', debug=True)

                              Step 3b) - if not 3a) ... That is, it this isn't the 1st time you are updating the modem's firmware

                              sqnsupgrade.run('NB1-40343.dup', 'updater.elf', debug=True)
time.sleep(5)
sqnsupgrade.run('NB1-40343.dup', debug=True)

                              Step 4) if 3a) and 3b) both fail ... by this point you might try this step too ...

                              sqnsupgrade.run('NB1-40343.dup', debug=True)

                              ... and yes ... since 3a) and 3b) failed me ... i did Step 4) as I didn't have anything to loose ...and it worked *yay-me*

                              - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

                              Lastly - a tiny explanation - as may be asking yourselves "Why do you run two firmware updates after each other?!?!?" - in Step 3a) & 3b) ....

                              As explained in the "Modem Firmware Update" in the docs: https://docs.pycom.io/tutorials/lte/firmware.html

                              "After you have updated your modem once using the recovery method, you can now flash your modem again using just the CATM1-38638.dup or NB1-37781.dup file without specifying the updater.elf file. However, should the upgrade fail, your modem may end up in recovery mode and you will need the updater.elf file again. The updater will check for this and prompt you if using the updater.elf file is necessary."

                                Step 1)

                                ###
### STEP ONE
###
import pycom
print('LOG: pycom.lte_modem_en_on_boot() # to check, should be False')
print(pycom.lte_modem_en_on_boot()) # to check, should be False

print('LOG: pycom.lte_modem_en_on_boot(0) #set to False if above command is True')
print(pycom.lte_modem_en_on_boot(0)) #set to False if above command is True

print('LOG: pycom.lte_modem_en_on_boot() # to check again if change was made')
print(pycom.lte_modem_en_on_boot()) # to check again if change was made

                                Step 2)

                                • A) It is imperative that you do a "HARD" reset of the board!
                                  DO NOT PRESS THE "RESET" BUTTON ON THE BOARD

                                • B) To do a "HARD" reset:

                                  • Un-plug any battery source you might have attached!
                                  • Un-plug the USB-mini cable from the board
                                  • wait a few seconds
                                  • Re-attach the USB-mini to power up the device
                                  • continue to Step 3)

                                Step 3)

                                ###
### STEP THREE
###
from network import LTE
lte = LTE()
lte.reset()
lte.disconnect()
lte.dettach()

# few AT commands to check if modem is alive and responsive
lte.send_at_cmd('AT') 
lte.send_at_cmd('ATI')
lte.send_at_cmd('ATZ')

                                If you got back your LTE() ... done the "Reset", "Disconnect" and "Dettach" ... and could execute the AT commands... continue to Step 3a) or 3b) in https://forum.pycom.io/topic/4022/unable-to-update-gpy-modem-firmware/24

                                    @combaindeft Thanks a lot for the in-depth step-by-step walkthrough! I will try this tomorrow, when I get my NB-IoT SIM-card back and i will share if it works for me as well.

                                    I really appreciate your help, thanks again!

                                      It works now for me as well!

                                      So following the steps @combaindeft suggested did indeed result in a successful upgrade of the firmware.
                                      One slight change: if using the upgdiff-file the updater.elf is not needed as @Paul-Thornton said, so for me (using an SD card)

                                      sqnsupgrade.run('/sd/upgdiff_33080-to-40343.dup',  debug=True)

                                      worked perfectly fine.
                                      (Update paused at 96% for about 15 seconds as described in the guide at https://docs.pycom.io/tutorials/lte/firmware.html - whole upgrade took about 5-7 minutes)

                                      So the whole process was:

                                      >>> from network import LTE
>>> lte = LTE()
>>> import pycom
>>> print(pycom.lte_modem_en_on_boot())
False
>>> lte.reset()
>>> lte.disconnect()
>>> lte.dettach()
>>>
>>> lte.send_at_cmd('AT')
'\r\nOK\r\n'
>>> lte.send_at_cmd('ATI')
'\r\nSEQUANS Communications\r\nVZM20Q\r\n'
>>> lte.send_at_cmd('ATZ')
'\r\nOK\r\n'
>>> lte.reset()

                                      Hard Reset

                                      >>> from machine import SD
>>> sd = SD()
>>> os.mount(sd, '/sd')
>>> os.listdir('/sd')
['NB1-40343.dup', 'updater.elf', 'upgdiff_33080-to-40343.dup', 'upgdiff_38729-to-40343.dup']
>>> import sqnsupgrade
>>> sqnsupgrade.run('/sd/upgdiff_33080-to-40343.dup', debug=True)

                                      This first upgrade took about 3-5 minutes -> it resulted in:

                                      SYSTEM VERSION
==============
  FIRMWARE VERSION
    Bootloader0  : 5.1.1.0 [33080]
    Bootloader1  : 6.0.0.0 [40343]
    Bootloader2* : 5.1.1.0 [38638]

  COMPONENTS
    ZSP0         : 1.0.99-3171
    ZSP1         : 1.0.98-3170

                                      I then did the full update without using the differential file:

                                      >>> time.sleep(5)
>>> sqnsupgrade.run('/sd/NB1-40343.dup', debug=True)
>>> sqnsupgrade.info()
<<< Welcome to the SQN3330 firmware updater [1.2.1] >>>
>>> FiPy with firmware version 1.18.1.r7
Your modem is in application mode. Here is the current version:
UE6.0.0.0
LR6.0.0.0-40343

                                      Thousand thanks to @combaindeft again for the great hint with the LTE.disconnect/reset/dettach
                                      This hint should be added to the renewed version of the upgrade guide.

                                        @florianrdt said in Unable to update GPy modem firmware:

                                        from network import LTE
                                        lte = LTE()

                                        hmm, if you can't do that ... then I think there is an issue with our board / modem ...

                                        What is our "main board?" ... a PySense, PyTrack or PyScan? ... you are using with your GPy?

                                        And ...

                                        • did you update the firmware on the "main board"?
                                        • did you update the firmware on the GPy?

                                        As it's most recommended that you

                                        • 1st - update the firmware on the "main board" to the latest
                                        • 2nd - update the firmware on the "Logic board" .. GPy in your case ... to the latest stable version.

                                            Was given a FiPY which had failed a modem upgrade. I have now tried almost every trick in the book and cannot get any life signs from the modem:

                                            
>>> import pycom
>>> print(pycom.lte_modem_en_on_boot())
False

>>> os.uname()

                                            It is not possible to create a LTE() instance, the board simply hangs. Any ideas?
