Hi Eugene, Can you explain in more details what you did to make it work. What do you mean by removed serial number for example ? My 11 inch, mid-2011 MBA just crapped out one day, I lost keyboard and mouse inside OSX (10.8), this was less than 1h after I had cloned my SSD with an image of Mountain Lion from my iMac (I regret this move to this day, was lazy redoing the install), and then after the crash I had to turn off the machine holding the power button. Since then I see the Apple logo but all I get is a loop chime sound (it barely finishes and I hear a little cracle and the chime sound starts again in a fast loop). I can't select an OS (external), did SMC + PRAM but nothing works. Plugging some usb flash drive on left USB will make it that only one chime then stop, but nothing else. I can't put up the OS selection menu :(.
I wonder if I deleted something on the SSD that makes it that the Mac won't boot and gets stuck on a reboot loop, is that even possible I'm unsure (where is the EFI located ? is it on the SSD or is it like a PC Bios inside flash memory on the logic board ?). I still find it extremely suspect that the MBA died right after I superdupered ML from another machine (iMac 27 late 09) :(.
I did order a replacement SSD from iFixit but it didn't do the trick, I even restored Lion that was originally on the SSD on it but still no go.
I'm thinking my logic board must have a defect (and all this isn't related to my superduper cloning but the timing is too coincidental IMHO) , but I don't know what to do and shelved already 250$ on the SSD, for pretty much nothing. If anyone has an idea it would be appreciated.
Thx
Chris

Eugene, where did you get a new Flash Memory? I had a working Macbook until I reset the SMC. Now I need to replace the Flash Memory but it's unclear what this would be or where I would get it. Thanks!

@Phil - The best answer here is bringing your system into an Apple Store. Apple has the needed tools to reborn your systems firmware. I'm not sure if they will do it for free on yours, they did three of our newer systems a few weeks ago.

Buy a new logic board and swap it. Most flash memory is soldered directly into the logic board.

I was experiencing the same issue with the same symptoms (green light on, webcam didn’t work) and basically my Macbook Air was a paperweight for the last few years until I came upon this post and disconnected the iSight camera and boom it booted up fine… Not quite sure what happened but I did replace the lcd screen maybe something of the webcam broke during that repair.

I was experiencing a similar problem. The MacBook would go no further than white screen and would continuously restart with a chime. It was a hardware issue and was resolved, as follows:
The way I went about it was to first remove SSD from the logic board, however, I had to put it back because it did not solve the problem,
Likewise, I removed the Bluetooth / airport board and put it back because it too did not solve the problem,
I then removed the I/O cable connection between the logic board and I/O board. This resolved the issue and MacBook booted normally!
I reconnected I/O cable back to logic board so as to narrow down and identify the exact fault.
It turned out that, the I/O cable, I/O board and logic board all were fine. It was the camera cable connected on I/O board which was at fault. I then put a shrinkable sleeve the camera cable to cover up its contacts and left it without connecting it to the I/O board.
The MacBook now boots up normally and works perfectly fine!
