Tips wanted for upgrading an Aeotec Gen5 ZW090-C stick

I’m going complete crazy here trying to upgrade my stick to version firmware version 1.02. I have tried it with a Windows PC (Windows 7), tried it with a virtual machine running Windows 10. I even tried it booting into Windows 10 on a MacBook (Intel). But I can’t seem to upgrade my stick.

I followed all instructions I could find on the Aeotec website. I installed all the available drivers they mention. But an upgrade keeps failing. I keep getting the error “Assert RESET_N signal (press reset button)”. After pushing the ok button, I get the error “De-assert RESET_N signal (press reset button)”.

The stick is running version 1.0 and I would like to upgrade it to make a NVM backup. I want to switch to a ZooZ ZST39 and want to prevent to have to re-pair every device. :slight_smile:

I haven’t tried upgrading using ZWaveJS UI yet, as I noticed that it could brick my Gen 5 stick.

Has someone here have the same issue before and have any tips on how I can resolve this issue?

Extra info: I can backup the stick using the Aeotec backup tool. I can turn the led on and off. That all works. I also noticed that the message says the driver is not installed correctly. However, I did install the programming driver and “better driver” from the site from Aeotec.

When did you purchase the controller? You can only upgrade certain versions.

production date 2018 or later, the update simply will not work on much older hardware versions.

from https://aeotec.freshdesk.com/support/solutions/articles/6000252294-z-stick-gen5-v1-02-firmware-update. VMs also unlikely to work according to that.

Your best bet is to contact Aeotec tech support.

I bought this one online from an other user. I have no idea when it was manufactured. Maybe this one is from before 2018. Would be bad luck I guess.

For what its worth, I’ve had my Gen5 stick since at least 2016 and was able to upgrade it (using Windows 10) a couple of years ago.

BTW I don’t know what’s wrong, but

may be the problem??
I made some notes when I updated mine, and here are my notes for installing the software:

3. Click on Install
   A popup "Would you like to install this device software?"
            Name: Sigma Designs Ports (Com & LPT)
            Publisher: Sigma Designs, Inc.
   Click "Install"
     Popup "The operation completed successfully".

Did you get a popup saying the operation completed successfully?

No, the operation will not even start. I get a timeout message after I get the errors above. Even with the new Sigma drivers. I think the problem may be, that the stick is too old. It’s hard to find out when it wast manufactured.

Guess, that if I want to switch to my Zooz ZST39, that I really have to repair everyhing. :frowning:

I have the same issue with a GEN 5+ bought in 2021. Firmware 1.1.
Can’t update to 1.2…
Do you find solution ?

No, i didn’t. I eventually switched to a new version of the stick that also supports S2.

I founded the solution.
When “Assert RESET_N signal (press reset button)” is displayed, you have to push the reset button on the Z-STICK Key and let pushed then release when asked…
I tried to update my key from 1.1 to 1.2. So I restored the NVM. Then replugged to ZW-JS-UI (see 1.2 goog). Backup NVM with ZWAVE-JS-UI and restore NVM to ZOOZ.
It’s fine.
All my modules are here except 2 FGS-224… Don’t understand why

Good to hear you found a solution for the firmware update.

I know it is a little late now but I had a the same issue as Lifelogger, last week, when I was trying to update to 1.02. I ended sending a note to support and they responded within a day. The recommended the following:

  1. Backup your Z-Stick Gen5 using this software: How to use Z-Stick Gen5 backup software (Backup, and Restore).

  2. Factory Reset your Z-Stick Gen5

  3. Run the firmware update to V1.02

  4. Confirm that the Z-Stick Gen5 is updated to V1.02 (LED will be solid yellow or solid green when LED is available)

  5. Now restore the network following the article in step 1.

It worked! I was able to migrate without any issues to ZWA-2 from NabuCasa. Hope that helps someone.

I cannot get my ZW090 firmware version to upgrade from 1.1 to 1.2 either.
I have tried the suggestions here but none worked.

In the Official doco it states…

“If for some reason your update tool is requesting that you press the RESET button, then the drivers were not installed properly. To fully install the correct drivers, follow “Method 2” to manually install the drivers over the Z-Stick Gen5.”
I do get this diagnostic. do what it says and then it tells me it cannot go into programming mode.

So I tried method 2 without success as well.

I cannot determine the year of manufacture as I cannot find any serial number on my stick either.
Has anyone got any suggestions other than repairing all my devices?

I finally got the migration done.

I submitted a support request to AEOTEC .
The first response was not helpful so I replied and was more succinct in my problem.
I had been doing every thing but

  1. Doing a Factory Reset after using their Gen5 Backup tool to backup my network.
  2. Running the firmware upgrader app as “ADMINISTRATOR”

After upgrading my gen 5 stick to 1.2, I restored my network to the the Gen 5 from the above backup.

I then plugged it back into my HA NUC, reloaded the integration and my network was still there.
I then plugged in the ZWA-2.
It was discovered and I then followed the on screen instructions.

All good now.
On the ZWA-2 :+1:

here is my personnale experience

Migration Aeotec Gen5 → Gen7 (without a Gen5+ stick in between)

:warning: This procedure is at your own risk. It is not officially supported and there’s always a chance of bricking the stick.

1. NVM Backup

  • Tool used: Z-Stick Gen5 Backup Tool
  • Instructions: How to use Backup Tool
  • Exported .nvm file before any firmware attempt (mandatory).

2. Firmware Update Gen5 → v1.02


3. Issues Encountered

  • Installed drivers via Method 2: Manual installation through Device Manager → update failed with:
    • assert reset_n signal press reset button
    • read/write operation timeout
  • Tried Method 3: Alternative drivers (CP210xVCPInstaller_x64.exe) → same errors.

4. Final Solution

  • Performed a full factory reset of the Gen5 stick:
    How to Factory Reset Gen5
  • Relaunched Z_Stick_G5_XX_V1_02_DFU.exe as Administrator → update succeeded.

5. Migration Result

  • Gen5 stick successfully upgraded to firmware 1.02.
  • Exported NVM and restored it on the Gen7 stick.
  • Whole Z-Wave network migrated without re-including nodes.
