So i have lenovo s820(android version 4.2.1),like 3 or 2 days ago i checked system update to check if there is any update available for my phone and luckily a upgrade for android 4.4 showed but i decided to download it later and after some days when i checked again it disappeared, i tried checking system update again again but failed all the time, i tried rebooting my device many times also did the checking method but nothing worked. help !
