Oh, man, corrupted system files is such a long shot considering what was going on just before it blew up. I mean, when build.prop got saved, it might've been saved into the wrong place or ... ?
And emusan's suggestion of a missing (or corrupt?) library file makes at least as much sense as init or fstab or any of that stuff.
.....
I just took a look into my kinda hosey dingo /etc and didn't recognize what I thought I was looking for ... I am, as we say in the tech biz, in over my head.
You know what? Here's what I'd do. I'd have someone use ClockworkMod Recovery to do a ROM backup and then install that file on vicinc's machine, again with CWMR.
What do y'all think?
