At the moment there are two way to resolve the problem of keypad for vodafone mobile. On vodafone branded mobile (K800 and w880) operator key and quick menu button are instead call and end-call button.
For people who wants to debrand his mobile, they should sustitute the keypad with a not-branded one or find the right patch to change the keypad map as in the vodaphone mobile. For people who wants to unlock, they just need the vkp for their vodafone firmware.
I unlocked my w880 (vodafone branded) patching the W880_R8BA024_MAIN_VODAFONE_AI_RED52.mbn. On my K800 instead I preferred a unbranded software and I substituted the keypad because I don't have the right knowledge about the keypad map and how modify it.
