I just reset my firmware (Alt+Cmd+R+P) hoping my new battery will get calibrated.
After the reset, the MacBook automatically started into Linux (debian jessie).
But instead I wanted to boot into Mac OS X Lion. So I rebooted.
But it never rebooted anymore. When I start the MacBook, the screen remains black, blank and dark. The LED keeps shining. There is no start sound anymore. It's gone.
I tried to restore the firmware using the Firmware Restoration CD.
But instead of blinking 3x fast, 3x slow, 3x fast, the LED blinks like several times really fast, when I hold down the Power-button.
I'm afraid, debian bricked my MacBook's firmware because it thought this was empty, free memory, right after the reset.
What can I do now? The Hardware is totally ok, but now the firmware is completely gone. How do I completely restore it? (I don't mind opening this thing, as I opened it a thousand times, to change the logic-board, CD-drive, keyboard …)

Asking here is already the third step! I already tried booting - the MacBook does not do any attempt to boot at all. Neither Alt, nor C, nor anything works, as I guess this all have been firmware functions.
+
+
And of course I swaped the RAM. The former RAM is perfectly working in my not so nice looking backup-MacBook, I recently saved from the dump.
+
+
There even is no start-sound. After resetting the PRAM / NVRAM / w/e RAM with this stupid combination ALT+CMD+P+R, the MacBook booted perfectly exactly ONE TIME! Into Linux! Which must have wiped out the firmware - that is the only explaination I see.
+
+
After the reboot(! ... I didn't even turn off and on the computer), nothing worked anymore.
+
+
That is why I ask for help restoring the firmware even by opening and flashing the firmware w/e chip by hand, violently, in any Apple-unsupported method necessary.
