Exactly my thoughts. What I think is, earlier, they were providing warranty only for unlocked bootloader like other companies (as mentioned on twitter, dated 13th Jan) then they realised they don't have any stock ROM flashing tool, so they said they'll also provide warranty for problems caused by flashing custom ROMs (which they said on 15th). That way they should stop providing warranty for custom ROMs when they launch their stock ROM flashing tool.Most probably flashing Custom Roms will also Void warranty, even Mi don't provide warranty after flashing Custom Roms ( only provides warranty against bootloader unlock, as it is required to flash phones through Mi flash tool). I don't see any reason why a company will actually give warranty against a thing they have actually not made( Custom Roms).
