I would say it's impossible for a card to be burned out by this.
Yes, there are images past this, here is the latest

I have got at least 5 different arm machines past this, only one had a glitch and resorted to unusal methods, someone did similar here
http://archlinuxarm.org/forum/viewtopic ... 713#p32342
The image he had was a lot older, glibc and filesystem had to be done together
The basic thing is if it appears it's all gone wrong, you prefix command with something, and give full paths, like this
So if you got to the point of bash upgrade, deleted the 3 directories, and --forced, you can continue
If the ls command begins to work, you are out of trouble and can reboot
No one can write a script because it depends on either how old a rootfs is, or when updates were last done.
We only pickup what arch does, at least that gives us a few days breathing space
