Sonoff Zigbee Bridge Pro, Problems with Firmwareupgrade on Berry Console

[Patrix2911]

Hello. First of all, I hope I’m posting in the correct forum. I purchased a Sonoff Zigbee Pro Bridge and flashed it according to this guide (https://notenoughtech.com/home-automation/tasmota-on-sonoff-zb-bridge-pro/#google_vignette). The installed Version is tasmota 14.5.0 I’ve reached the ‘cc.flash’ point in the Berry console, but I’m getting the following error:

FLH: Flashing started (takes 5-8 minutes during which Tasmota is unresponsive)
stack traceback:
: in function flash
: in function main

I’ve tried with the file ‘SonoffZBPro_coord_20220219.hex’ and also with ‘SonoffZBPro_coord_20240710.hex’. Unfortunately, I keep getting the same error. I’m not very experienced with this, so could someone please help me?

Thank you very much, Patrick.

Can you please provide the full log, not just the error?

I will try later this week on my side. Can you confirm that you didn't flash any other firmware on the CC2652P ? It still contains the factory firmware from Sonoff?
