Hi, Ive had my MBP 2011, i7 for several days now and it was going well until I had updates come up for Thunderbolt (something like that), SMC\EFI? I clicked to reboot & install and decided to wait it out as they were small. After about 10 mins it was still stuck at the gray apple screen with the spinning wheel below it. I then decided to leave it at that for the day, went out for about 8 hours came back and it was still there? (I know you shouldnt) but I turned it off and fired it back up.. It came up and 2 seconds later powered down. Since this time I've: 1) Tried safe mode (left shift), same result 2) Tried Command + S and did a fsck and it came up wuth invalid node structs. So booted off the install disk and disk utility found issues and wouldnt repair 3) Tried DiskWarrior, and that didnt like it any more, just booted so far and halte with 3 beeps (repeatedly - usualy denotes memory issue, but the beep codes ONLY happen with DW) 4) Decided to install to an external drive. Which went well until I first logged in. NOTHING worked, only the dock. With an error "finder quit unexpectedly" ignore does nothing. None of the apps work. Did another disk utility check and all was well on that drive other than the permissions. 5) The pup decided t chew the bloody external drive cable in the process so that a no-go now 6) Booted off install CD again, removed the partition, added another, gave it another name (just incase) and set it to Extended \(journalled) and zero wrote it. Did a verify, and there were node issues?! Did a repair, and it fixed something, verified again, and it was ok. (This was odd as I had just cleared the lot? ANy clues here?) 7) Installed OSX 10.6.7 again, fired it up, dock there, everything else dead as in (4) above. Did the same thing, and same problems. 8) checked /private/var/log/install.log to see what was there, and woah betide me there were OLD entries from previous installs? Regardless whether or not I nuked and zerod the pertition. 9) Tried an SMC/PRAM reset, did nothing 10) Did a hardware test (which I did when I first got the "craptop" which passed all on the extended) and as soon as I pressed "test" on te quick test, it hung on memory. I did try memtest86 from another boot CD which I use and it was happy with the mem after 10 extensive passes. My questions are: Is there a bootable way I can reinstall the "stock EFI and SMC and Thunderbolt" firmware, have I missed out any testing steps or other "resets" like SMC\PRAM?. And where is a good source of valium as I'm on the edge of a vervous breakdown! I hope you guys can help Thanks Adrian Edit: Excuse all the weird slashes etc...as you can see I'm not too accustomed to windows laptops!! Someone save me from the abyss!
