Hero update give yellow exclamation point

[UserName872]

Hey everyone I wanted to see if anybody had some advice on the 1.29-1.56 update. I have tried several times including multiple hard resets to get my device to update. Each time the update downloads successfully but after the phone restarts and shows the progress bar unzipping the package it stops halfway and shows the phone with a triangle and a yellow exclamation point. Any suggestions?

i have the exact same problem, its seriously annoying. Have you managed to sort it out? Ive tried the hard reset, the lot. Everytime it tries to update OTA it resets, starts to unload the package and them gets half way and shows the explamation mark. No idea how to get over this at all

I know this is a WAY OLD thread, but to nolimit, just go get the 2.1 RUU from Sprint and run that. Then you will be up to date. Plus, it's not an OTA update. You just DL it, connect your phone to your PC and then update it. It's on the Sprint website, and the HTC one as well.
