Z2M - Zigbee device not working after flash sonoff dongle

[fallen brook]

Hello 👋

I just flashed my CC2652P coordinator https://www.amazon.fr/dp/B09KXTCMSC?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_3) using (https://dongle.sonoff.tech/sonoff-dongle-flasher/) to the latest firmware, because I was not able to pair an Aqara device (https://www.zigbee2mqtt.io/devices/RTCGQ14LM.html)).

The dongle seems recognized by my Raspberry Pi / Home Assistant, and I succeeded in pairing the new Aqara device ✅
But all my older devices stopped working ❌

I’m now seeing these errors:

z2m: Publish 'set' 'state' to 'Module spots Salon' failed:
Error: ZCL command 0x08ddebfffeeeb25b/1 genOnOff.off(...) failed
(Timeout - 59734 - 1 - 12 - 6 - 11 after 10000ms)

z2m: Failed to read state of 'Spot salon 3' after reconnect
ZCL command 0x5c0272fffe2df495/1 genOnOff.read(["onOff"], ...) failed
(Data request failed with error: 'MAC no ack' (233))

z2m: Failed to read state of 'Spot salon 2' after reconnect
ZCL command 0x5c0272fffe2df605/1 genOnOff.read(["onOff"], ...) failed
(Data request failed with error: 'No network route' (205))

My network_key, pan_id, and ext_pan_id did not change.

Here’s an extract from my Z2M config:

  "restart_required": false,
  "version": "1.41.0",

}

👉 Does anyone have an idea what could be wrong, or how to get my old devices talking again?

Battery devices may take a bit to wake up. Otherwise not sure.

Yeah it seems to be the case I start receiving information from devices, damn that's slow !

The mesh need to be recreated from scratch or ?

Reboot

[fallen brook]

already tried that

it seems that randomly some are disconneting O_o

hope that the sonoff flash did not break anything

I still got a lot of :

[2025-09-27 18:52:42] error:     z2m: Publish 'set' 'state' to 'Prise Eclairage Pipistrello' failed: 'Error: ZCL command 0xa4c13828b517e3e8/1 genOnOff.on({}, {"timeout":10000,"disableResponse":false,"disableRecovery":false,"disableDefaultResponse":false,"direction":0,"reservedBits":0,"writeUndiv":false}) failed (Timeout - 19810 - 1 - 4 - 6 - 11 after 10000ms)'

After 1 hour and half of rebooting :/

And device seems to work but the stuff are very slow

New error :

Give it a bit to sort out
