Trying multiple recommendations listed on this forum, neither helped:
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;
followed by reset as in (1) - same result, it keeps asking for root password.
3) reflashed with R15.1.0.004 Firmware for Generic
and repeated (1) and (2) - still no change.
What could I miss?
Some additional details about the FX30:

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.
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:
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?
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.
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.
Well, according to dmesg there are only three new devices registered (/dev/ttyUSB0,1 and 2) when connecting usb cable:

In some other thread I saw that there should be separate devices for these UARTS, but not in my case
Okay.
Lets return to my question regarding possibility to erase user partition from bootloader.
Is that possible? Or the bootloader allows to download firmware only as mentioned in the description of the “AT!BOOTHOLD” command?
