I have been using z4 root for temporary root because I was a little nervous about doing the permanent root. It has been working fine and I was even able to uninstall some of the sprint bloatware with help from titanium backup app. My only problem is that I would like to now update my phone to 3.70 for the full version of swipe and a few other things but when I try to update my phone, it fails. I have tried the OTA and the manual version.
With the manual version, it goes through recovery just fine and when i choose applysdcard:update.zip it extracts and starts but then ends with this error message:
Installing update…

E:Error in /sdcard/update.zip

Any advice would be greatly appreciated! I'm on the verge of replacing the EVO and passing this off on my husband.
