Twice now, I've successfully used AR recovery routine to install the 2.1v3 (rooted) on my Eris, (previously running the original "v1" root). Install was a breeze--tho' I had to "push" the recovery .img and the flash routine by dragging them onto the SD/into nested "system" and "bin" folders manually while mounted to my Mac, as the first command prompt instructions generated error messages...the remainder of the command prompt instructions then executed successfully on my girlfriend's Windows machine, where I could install the SDK. I restored my Apps...got everything set up, widget-ed, etc. All well until I turned my phone off when going to the theatre...on powering back on: got to lock screen, but when I unlocked I had a black screen with an "unexpectedly stopped. Force close and try again" message for com.htc.launcher. When I click the Force Close button, I immediately get another dialogue saying com.htc.mms has stopped...and then the first, com.htc.launcher dialogue pops up over and over, with the background behind never therefore progressing beyond the black screen with silver/gray "htc" logo. Have just gone through this entire life cycle for the second time. Has anyone else seen this behavior, or have any suggestions? The one reference to massive cascades of FC's I'd found mentioned Facebook sync as a possible problem, so I didn't enable Facebook syncing this second time...apparently that wasn't the problem. Help! Or I'll never be able to turn my phone off again.
