I am gettng the same basic problem as the OP. I'm not as experienced but in the past I've flash a friends evo and a HP touchpad several time so I'm not a complete novice at this. Basically I'm also at the point where I can't get anything to flash, largely for mounting issues as far as I can tell. So i'm trying to RUU and it fails just like OP except with 12 failures instead of 43. Can anyone post what the solution was or help me through it? Thanks so much.
