Morning, Morkhans.
Yes, I was reading the OpenWRT link some days ago, and believe me if I tell you I was tempted of experimenting the new SA-Vodafone soft (Firmware Upgrade 256.11.10.06.105.SP04, I think so) with your update procedure basis.
You say: "I have personally bricked one router and at least one other forumite has reported bricking theirs".
As far as I´m concerned, that would be a painful assertion when the router-modem is an expensive B970.
Well, I´ll study thoroughly that and perhaps I´ll update it... crossing fingers.
At least, in the worst case, I´ll have a big dongle working as modem with Mobile Partner.
Thanks.
