I have problem with system update on my two weeks old Lenovo IdeaPad K1. The system update sign (big rectangle) will keep popping up. Lenovo tech support says they only support hardware and not software. For software issue they ask me to contact Android. That is something surprising to learn that now I have to deal with two parties. I can send unit back. But I can not reset the system or can not delete my personal information (location on the map, owner name and phone, g mail accounts (in box and all). It seems like no good product from Lenovo or not a great support. Will appreciate any ideas to delete personal info. before I return it to fix.
