Currently I am running 4.5.0.131 on my sprint 8330m. My available ota upgrade on my phone is 4.5.0.175. I have tried the ota download and desktop manager and I keep getting errors on both. On my phone the error message says update request failed. Try again later or use desktop. When I tried to download the upgrade with desktop, I get that the download failed check internet connection. My internet connection is working fine on both pc and phone. I know I am two upgrades behind..is that part of the problem? Is this a Rim problem or something else? Any help would be so appreciated!
Do you have a broadband internet connection? You can't download an an OS using dialup... also, did you try downloading the OS from Sprint's site or RIM's?
