Looks like a broken flash Hi,. Can you help us and explain us how the flashing process work ? From what i've seen, it's seems that we have multiple copies of the boot loader ( seems to be at least two). And the upgrade seems to write a new version , calculate the checksum and after that switch to t...

From the diagnostic information you provided, I see 2 separate problems. Problem 1: The z-way-server.log file shows an error executing serial API command 0xF4. This is a proprietary command (i.e., the purpose is not public knowledge, although we can infer from the error message that the command doe...

Please try to upgrade using the Z-Way UI as suggested by seattleneil Hi, I tried without success and also did the same thing with another host machine ( first was a raspberry pi, used for year with the dongle, second is a intel haswell generation computer). I have the full log from z-way if wanted....

You've reached the limit of my understanding of the ZMESerialUpdater tool. Does the log file (zme_updater.log) reveal why you're getting the error "Can't write NVM data! at=4200"? I run the ZMESerialUpdater as root. Could it be a permissions issue (I'm just guessing)? If you're still stuc...

In looking at https://service.z-wave.me/expertui/uzb-stats/versions-graph.html?hw=277, the bootloader filename is: UPD_bootloader_UZB500_from__05_17_to_9D04.bin (which you already knew). Just checking... I assume you've stopped the Z-Way firmware when you are trying to run the ZMESerialUpdater comm...

This is a point of confusion. The filename uses hex digits and the UI uses decimal digits. You already have the most recent firmware (0x17 = 23 decimal). As for changing the frequency, you can download a shell script from Z-Wave.Me: https ://z-wave.me/download/changezwf.sh Once downloaded, run from...

Go in Controller Info, press Debug and then back to change the frequency Hi, i was already able to go back to EU frequency scheme. The issue is that i cannot update the boot loader version ( blocked with 29304 version ). Can you please help me and tell me which boot loader and firmware file i shoul...

Hi rafale77, I had the same problem as all above. My UZB-Stick status was 5.23/29304, so I tried to upgrade bootloader to 40196 with file UPD_bootloader_UZB500_from__05_17_to_9D04.bin But the upgrade procedure with ZMESerialUpdater serialapi_uzbupdate -b UPD_bootloader_UZB500_from__05_17_to_9D04.bi...

Hi,

Anything have changed about the issue ?
I’m encountering the exact same thing .

I also encountered JP frequency switch issue ( from EU) during the upgrade journey before being stuck with boot loader 29304/7278.

Thank you in advance ,
