Trying multiple recommendations listed on this forum, neither helped: 1. holding for 10 seconds reset button while powering FX30: the RSA key is reset (fingerprint is different) but it keeps asking for root password instead of prompting to change it; 2. trying AT RMARESET command: ```auto AT!RMARESET=1 !RMARESET: DEVICE REBOOT REQUIRED Items Restored: 1282 Items Deleted: 26 Items Defaulted: 0 Items Skipped: 5 OK ``` followed by reset as in (1) - same result, it keeps asking for root password. 3) reflashed with [R15.1.0.004 Firmware for Generic](https://downloads.sierrawireless.com/airlink/FX30/CatM/FX30_WP77xx_full_R15.1.0.004-generic-SWI9X06Y_02.36.08.09.cwe) and repeated (1) and (2) - still no change.

Does this help? > [@Factory Reset FX30](https://forum.sierrawireless.com/t/factory-reset-fx30/27337/3): > > Thanks for the suggestion, but this command also didn’t work. After that, I connected through serial instead of ethernet, and I was able to use AT commands through that connection. I then reset the FX30, and I know that I successfully reset the FX30 because I had to create a new password whenever I connected again via SSH. What I’m confused about is that everything remained the same on the Octave website (virtual resources, edge actions, observations). I thought that a factory reset would reset … ---

Unfortunately no. I have tried to do reset using following command: at!entercnd=“A710” at!rmareset=1 it didn’t help and still asking for the root password, that’s confusing. ---

Have you tried the (AT!FWD=FACTORYRECOVERY,ENABLE) command which enables factory reset via the push button? You can also see here > [@\[FX30-4G LTE-M\] Wrong /etc size in ls FW14](https://forum.sierrawireless.com/t/fx30-4g-lte-m-wrong-etc-size-in-ls-fw14/25578/8): > > I tried the swiflash method on the R14 and it doesn’t work (as expected). In all case, the swiflash is not viable for us since we need to erase the overlay on FX30 that are not connected to the PC. Could you confirm that our script that clean the overlay, do enough erasing (we want to create the same behavior as reset.cwe does)? ---

Yes, I did it multiple times, to verify that it is enabled: … AT!FWD?FACTORYRECOVERY ENABLED OK … then press reset button, power ON the modem and keep pushing the reset button for \>10seconds. On the next boot, the RSA key is different, but it still prompts for the root password instead of setting new one. Also tried to flash older R11 release FX30\_WP77xx\_full\_R11.0.0.007-generic-SWI9X06Y\_02.16.06.00.cwe and repeat all the procedures: - reset using reset button - AT!RMARESET=1 - swiflash -m “wp77xx” -r None worked. ---

unfortunately this can be done if I have ssh access to my modem… Could you please explain how to get access to linux shell using second UART? I don’t want to reconfigure working UART1, which is used for AT commands, because I will not be able to reset it. Also is there a way to reboot into bootloader and erase user partition from the bootloader? ---

you can turn the 2nd UART into console port by AT!MAPUART=16,2 ---

Yeah, I know the command, sorry for the confusion. My question was about physical connection? If it’s over the same USB, I don’t see any new /dev/ttyUSB\* after enabling that port with AT!MAPUART=16,2 In my case there are /dev/ttyUSB0, /dev/ttyUSB1 and /dev/ttyUSB2 The AT command service is on UART1, which is /dev/ttyUSB2 in my case. I have tried to use both /dev/ttyUSB0 and /dev/ttyUSB1 after enabling second UART, but neither seems to work as linux console. ---

I believe /dev/ttyusb2 is from the AT port of usb , noy uart And /dev/ttyusb0 and /dev/ttyusb1 are all from the usb port, not uart ---

you are right, /dev/ttyUSB2 is the AT port of usb. So, you are saying, that “AT!MAPUART” command will not have impact on behavior of the /dev/ttyUSB2, am I right? I still don’t understand how to connect to UART1 and 2 in order to start using them. ---
