Same problem here! I have updated my firmware from k800 vodafone to k810 generic. I want those button for send/end. Anybody can find a patch? I`m searching about 2 days and I didn`t resolve my problem.
No. Only K800 have Vodafone branded SW.
K810 haven't Vodafone version !!!
You can resolve your problem -> just again flash with K800 Vodafone SW and "send/end" buttons work :D
