Followed the procedures here as well and still my 8110 will not accept an update from 4.3 to 4.5. I honestly think that There is something physically on the phone that will keep this update from happening. After several texts from RIM about how I have to update it still doesn't work. I'd contact them, but unless they find the fault to be with them, which is solely at their whim I have to pay for any advice on their part. However, I don't see how I should have to pay for anything since I've followed all of their and your directions multiple times over the last 3 months and still can't upgrade to 4.5, even when AT&T offers the upgrade, this is ridiculous. iPhone here I come, I think..??..
