FLS-PP F/W upgrade not working

I am using 2 FLS-PP with Home assistant / Zigbeeto MQTT Stack and recently my leds started to stay steady green upon powering up. I checked the forum and this looked to be the same behaviour as Hue Bridge V3 bug. i can power on/off, leds are steady green, but RGB light control or any other feature unresponsive via MQTT.

Did a full reset of FLS-PP, then reactivated old Rpi4 with Raspbee II gateway and attempted to upload new firmware 0x201000F8, via Deconz OTAU update , as doing so via HA/ZGBtoMQTT OTA upgrade was timing out.

On deconz, upgrade from 0x201000F5 is smooth with no errors in 9 minutes, but the FLS is not upgraded upon reboot. see screenshot. Resetting to factory and attempting the same make no change, firmware stay on same version. F/W file was downloaded directly from Dresden support site.

What do i miss here ?

I have the same problem here with at least two FLS-PP (third one not yet checked). Those two have date code 20220105.

One of the two does actually switch from green to yellow color after update, the yellow color blinks a few times, and at the end the firmware still reads as 0214.201000F5. The other of the non-working ones does not even switch to yellow after upgrade, it simply does nothing and version also keeps at 0214.201000F5.

One other FLP-PP with date code 20251007 and firmware F6 did upgrade successfully to F8.

Upgrading was first tried with Z2MQTT (didn’t work), then I re-joined them to a ConBee II and tried with deCONZ (same behaviour as @KipiKland).

Any help will be appreciated.

I made some exchanges with Dresden E. Support, and then nothing more about the next steps.
I only noticed that i had apparently 2 generations of FLS-PP:

The older one, which i was finally able to update to F8 was having ST Micro - ST25P40VP Flash memory

The newer one, still impossible to update having Renesas - AT25SF041 Flash Memory.

I reminded support for a new answer but i am still waiting for it…

Thanks for the update, though it is a bit … underwhelming.

I just checked my 4th FLS-PP, this also has date code 20220105 - and consequently didn’t work either.

The F8 firmware was released last year exactly for this reason (color setting won’t work). I don’t have high hopes for a fix. That makes 3 FLS-PP heading to electronic waste for me, certainly not to be replaced by anything from Dresden.
