Would it be possible for someone to check on the links provided by the .RAR files? I've been trying to download the necessary .PUP files in order to upgrade my PS3 from 3.55 to 4.46, but my download speed slows to a crawl as soon as the process begins at 14 KB/s. I doubt it's my internet since I subsequently ran speed tests, and I even tried downloading through multiple browsers. Unfortunately, nothing has worked, and my computer tells me that the file has finished downloading when it's only 15 of 201 MB in size. Can anyone explain what's going on?
