@RobbieThe1st: Thanks, a rootfs with a working copy of your flasher tool would be much appreciated - I wiped it out the moment I reflashed to the stock PR1.2 fiasco.

But really, I'm thinking more of sending it to be repaired (at a cost) to the local Nokia distributor/service agent. But if it can be revived through any other means (however unlikely as that may be), the better.

As of now, chances look slim though. And booting from SD card sounds like a dodgy solution from a long term point of view.

Okay, now that we've kinda established that the eMMC might be dead, let's move on to discussing WHY, shall we?

Reasons I could think of:
1) OC related write errors (Can eMMCs/flash memory in general get bad sectors? I thought that was a HDD related problem).
2) OC related voltage issues (Was running it undervolted, but isn't that only CPU/DSP related?).
3) Me zapping the chip with static when I opened her up.

Anybody else?
