I had a root go flaky, got it bootable, then tried to restore factory settings, I flashed the bootloader image out of order and lost ability to communicate by usb to flash any other files.
But, the folks at Best buy were nice enough to replace it for me, when I explained what happened, they pointed out that with the replacement plan I bought I could have run the thing over with a lawnmower and brought the pieces in and they would have replaced it.
I am not screwing around with rooting again though.
I had unlocked it.
Flashed the rootboot
flashed the recovery (clockwork crespo?)
then it would only boot to a menu with mount options and other sys level stuff
I flashed a boot.img that got it back to the os
put the power user app on
then it wouldnt go into the os again, only the sys level menu
flashed the boot.img again after going around in circles for a scary hour or so
got back to the os and decided screw this and tried to restore factory settings
then it wouldnt boot again, got stuck at the "Google" screen with the unlocked icon
went back in and flashed system.img and tried to flash recovery.img from the original rom, that failed.
Thats when I flashed the bootloader.img and removed the ability to communicate via usb to flash any further.
