If you don't have PC then you only have one option go to service centre and update with them & for God sake stop complaining about Samsung for server problem it's because of millions of s7 users are downloading update thru ota. So it's up to you guys.
We do apologize for the inconvenience caused. We would like to inform you that the case is already known to Samsung and the device will be able to download the update as per its baseband version as earliest. Thanks again for your patience!
