Seems you are not using FX30 FW:

I don’t see problem to use UART AT command port:

your link is for standalone WP77 module.
For FX30 with WP77 inside, you can use this:

this is the link you provided me previously for the FX30S

Ok I will use the new link, but will I use Firmware for ATT or other?

It depends on your network carrier.
If it is not ATT or verizon, you can use generic one.

Please note that you can still use WP77 FW, as inside your FX30, it is still a WP77 module.
But people will prefer to use FX30 FW for FX30 device as it contains extra feature.

I found this procedure

I am no expert! Can you give me more details (or a more detailed tutorial) explaining how to use SSH to run FW.

thanks,

#8

you can use teraterm to open SSH on 192.168.2.2
For transferring the CWE file, you can use WINSCP tool

#9

Is there a password?

#10

I don’t know if you set it before, i just use “root” for username

#11

Hi,

I still can’t seem to fix the problem, I’m not used to using these tools. is it possible that i give you Teamviewer access to my computer so that you can see with me to update the firmware? if so, we can make an appointment.

#12

What is the problem now?
Can you ping 192.168.2.2 from your PC?

#13

Yes I can ping 192.168.2.2

He ask me a password!

I don’t know the password of your device…

Another unofficial way to update module FW is as follows:

  1. download a WP77 FW EXE
  2. use 7zip to extract it
  3. there should be a fdt2.exe inside
  4. put the new xxx.cwe inside the same folder
  5. use command prompt to update by “fdt2.exe xxx.cwe”
