This file needed if you can not download OTA updates on the phone.
Please note that there is 2 different model number in this particular phone, this update works with : KN19 , not with KN16
You can find out which yours is , by checking it in the settings -> about phone menu.
Just downoad this file to your phone memory or an sd card in the phone , then go to settings ->about phone->system update , then tap on the 3 dots and choose manual update from the menu.
Then point to the file ,phone will ask if you want to update, answer yes.
Thats all.
Hope someone find this useful. Quite a large file, so might take some time to download.
