OK, everything looks normal. (1 bad block in /cache, but I don't know why that would cause a problem)
Go ahead and flash a ROM file after performing a
wipe -> wipe data/factory reset
Watch the screen carefully for any errors (indicated with an "E:")
If flashing of the ROM succeeds, power the phone off with the menu, start it up in fastboot mode (Send+End), and then perform a flashing operation of the recovery partition:
fastboot flash recovery recovery-RA-eris-v1.6.2.img
Then, after waiting for all visible activity to cease on the screen, pull the battery, re-insert it, and power the phone up normally. It will take quite a bit longer to get to the initial screen than normal, but that is typical for a first boot.
Let me know if you see any errors anywhere - watch the phone closely through all these steps.
