unable to flash Sonoff ZBDongle-E as a router

[wolfgang-muc]

Silabs flasher (Chrome on Windows 10 or Ubuntu 22.04) shows immediately after selecting the file:
Auf darkxst.github.io wird folgendes angezeigt:
Failed to parse firmware: PythonError: Traceback (most recent call last):
File „/lib/python3.11/site-packages/universal_silabs_flasher/gbl.py“, line 118, in from_bytes for tag_byres, value in parse_silabs_gbl(data):

Zigpy.ota.validators.ValidationError: Image is truncated: tag value is cut off

Flashing with putty on Ubuntu:
I'm setting the dongle in boot mode, getting the boot loader displayed, select 1, getting the "C" start the xmodem transfer, but nothing happens. When i close the xmodem terminal, putty several times shows the boot loader and i can select between 1-2-3 again.

Can you help?

Thanks
Wolfgang

Hi guys,

same over here! Would be great if I could flash the router-fw easily to finally use my second ZBDongle-E.
Anyone knows if this is a known bug which is beeing worked on?

Regards,
Sven

Hi guys,

yesterday I was able to flash the fw without errors - layer 8 problem. ;) I downloaded the fw-file through "save link as" via the following site, which gave me a 313 kb "Z3RouterUSBDonlge_EZNet6.10.3_V1.0.0_direct.gbl". The one I was not able to flash.

When downloaded "Raw" (see the next image) the filesize changed to 281 kb - the fw-file I was able to flash without any problem. Maybe this will save someone´s day... @wolfgang-muc @aro78

Both files to compare:

Thanks @ganJAHman, the proposed solution worked for me (I had the same problem).
