Sprint halts EVO 4G update due to reports of it bricking phones

Oh oh. There's been a tiny little hitch in the latest EVO 4G update, which has resulted in a number of people finding their superphones  becoming unusable. Aside from rooted handsets having their predictable woes with new official software, some users have found that applying the update twice bricked their phones, stock OS and all. That's pretty worrying, particularly when you consider that checking for updates after a successful install gives you the option to apply it all over again.

Sprint and HTC have acted quickly to pull the OTA for the moment, and promise to restore it as soon as its lethal streak has been ironed out:
      While the vast majority of consumers successfully downloaded and installed the most recent HTC EVO 4G software update, we have received a handful of reports from customers having some issues with the update. In light of this, HTC and Sprint have decided to temporarily halt distribution of this software release until we can investigate further. We expect to be able to resume software updates shortly.
