Hi freaks,

happy Christmas first!!

Unfortunately I'm not able to finalize the flash on 1750e Repeater, tried out with 2 items.

Any ideas?

Thank you

don't own the device, but I think the wiki entry's confusing.

you either have to use the -pnvd or the debug and passive commands, not both.
running them inside the ftp client while using the command line params, disables them again.

Hi frollic,

your hint was correct!!

start with:
**ftp -pnvd 192.168.178.1**
but no:
ftp> **debug**
and
ftp> **passive**

Log and pls update the OM:
