I was using 2.1update1 which was rooted using easyroot. I deleted a few stock applications that i didn't need such as corporate calendar, visual voice mail, and amazon mp3. Now after attempting to apply the OTA 2.2 update, i receive the following error message: assert failed: apply_patch_check("/system/app/CorpCal.apk") followed by a bunch of numbers and letters and then E:Error in /sdcard/update.zip (status 7) Installation Aborted. Any ideas what I'm doing wrong? Did i need that Corporate Calendar app for some reason? Thanks for your help.
