how to install firmware via ssh ?

[CrashXRu]

There is a need to install the firmware via the router's cx console
how to do it?

I know that you can unpack the firmware using binwalk

binwalk -e GT-AC2900_3.0.0.4_386_41793-gdb31cdc_cferom_ubi.w

I checked the sections and realized that the unpacked parts do not correspond to one of the sections

?

bcm_flasher or hnd-write

For older routers

mtd-write2 RT-AC3200_384.11_2.trx linux
or
mtd-write -i /path/to/file.trx -d linux && reboot

I found this in @RMerlin's repo:

~/asuswrt-merlin.ng/release/src/router/rom/webs_scripts/urlfw_webs_upgrade.sh:
    8  dl_path_SQ_beta="https://dlcdnets.asus.com/pub/ASUS/LiveUpdate/Release/Wireless_SQ/app"
    9  dl_path_file="https://dlcdnets.asus.com/pub/ASUS/wireless/ASUSWRT"
   10: #wget -q -y -O- ${path}/${file} | hnd-write -
   11 
   12  echo "---- URLFW To download fw/rsa, Start ----" > /tmp/webs_upgrade.log
   ..
   77  if [ "$update_url" != "" ]; then
   78      echo "---- wget fw nvram webs_state_url ${update_url}/$firmware_file ----" >> /tmp/webs_upgrade.log
   79:     hnd-write ${update_url}/$firmware_file
   80  elif [ "$forsq" -ge 2 ] && [ "$forsq" -le 9 ]; then
   81      echo "---- wget fw sq beta_user ${dl_path_SQ_beta}${forsq}/$firmware_file ----" >> /tmp/webs_upgrade.log
   82:     hnd-write ${dl_path_SQ_beta}${forsq}/$firmware_file
   83  elif [ "$forsq" == "1" ]; then
   84      echo "---- wget fw sq ${dl_path_SQ}/$firmware_file ----" >> /tmp/webs_upgrade.log
   85:     hnd-write ${dl_path_SQ}/$firmware_file
   86  elif [ "$urlpath" == "" ]; then
   87      echo "---- wget fw Real ${dl_path_file}/$firmware_file ----" >> /tmp/webs_upgrade.log
   88:     hnd-write ${dl_path_file}/$firmware_file
   89  else
   90      echo "---- wget fw URL ----" >> /tmp/webs_upgrade.log
   91:     hnd-write ${urlpath}/$firmware_file
   92  fi
   93  wget_result=$?
   94: echo "---- [LiveUpdate] hnd-write fw, exit code: ${wget_result} ----" >> /tmp/webs_upgrade.log
   95 
   96

As far as bcm_flasher is concerned it comes prebuilt. Either @RMerlin can tell what it does or somebody should risk and check it.
