Q: Data recovery after failed 10.10.4 update
So I updated to 10.10.4 and now my MBP won't boot. Get's about 1/3rd of the way through the loading bar and crashes. Can't reinstall Yosemite from recovery mode, can't repair permissions or the disk with disk utility, can't reinstall 10.10.3 booted from a thumb drive, and can't get a "borrowed" version of DiskWarrior 4.4 to work. Fsck also crashed when I tried to repair with that. I can wipe everything and do a clean install of 10.10.3 but I'd like to get my data off first as I haven't backed up my HDD in 9 months (I know, I know...). Since this is purely a software issue I should be able to get all of that data back, correct? Can anyone recommend what tools to use or how to go about doing this?
Here's what I'm working with for hardware options at the moment:
Failed mac: 2012 MBP, 500gb HDD
Working mac: 2010 MBP, 250gb HDD (my girlfriend's computer)
1TB external HDD, partitioned into 500gb time machine backups and 500gb storage with ~150gb of files
64gb USB stick
MacBook Pro, OS X Yosemite (10.10.4)

Problem solved. I was able to set the hard drive to ignore permissions from "Get Info" and am now copying my entire user account over to my external drive. After that I'll reformat the hard drive and do a clean install.
