FX30 3G: broken pipe error when running fw-upgrade

IoT Gateways FX30
1

After update the firmware, I cannot run further updates or run modem commands like “cm info”. We believe the first update was with a partial image, so we would like to overcome the error message or reset to the original firmware and try again.

  1. Coworker set up a FX30 and updated successfully, who then instructed me
  2. I started with a fresh FX30 3G (PN:1103214)
  3. followed instructions to set up the leaf environment in a Ubuntu 18.04 followed instructions to set up the leaf environment. We added minor steps to stay in Python 2.
  4. obtained firmware image, “.leaf/wp85-modem-image_17/9999999_9904559_SWI9X15Y_07.14.01.00_00_GENERIC_001.042_000.spk”; firmware updated successfully
  5. “fwupdate query” shows up-to-date firmware and bootloader but factory versions of legato, linux, and fx30 (see info at the end)
  6. “fwupdate download {any file}” returns

Error in download, cat: write error: Broken pipe

  1. Similar results after transferring the file and running it inside ssh. Similar results unpacking the spk file into cwe files and trying one individually.
  2. We notice the spk file we initially used does not contain as many cwe files as “.leaf/fx30-3g-image_1.0.1/9999999_9904559_SWI9X15Y_07.14.01.00_00_GENERIC_001.042_000-full.spk”, so maybe the missing updates are causing the issue
  3. The Windows FDT2 tool command:

fdt2.exe -d wpspk -fd firmware GenericFull.spk -force -log firmware

returns:

Firmware download failed - firmware and PRI version mismatch.

  1. I noticed “at!image?” showed the active FW image is deleted (slot 255) and a different version than PRI, so I deleted both using “at!image=0,0”, but similar results.

Here is my modem info:

I forgot “-f” in the windows tool. I corrected that typo and it seems to have worked! The Windows tool was able to perform the update, maybe since it didn’t use VirtualBox.
I used the “full” spk file to avoid getting stuck again.
