@fahadj2003: Thank you for the attempts to help, although like I said in my case, whatever you do, the eMMC is simply not detected (in multiple versions of Windows and Fedora, I might add - thus the need to go to Ubuntu for a second try).

It just gets stuck in the loading screen (and what's different from the guy in the link you posted, it gets stuck for HOURS WHILE the dots are STILL MOVING, and it's not stuck on the second dot). I have tried popping out battery and popping in back again during the eMMC process, with or without pressing "u".

And yet, a few days before, I could reflash everything without even a single problem. Similarly, a few weeks before that. Something went wrong somewhere along the line.

Anybody has a rootfs image with the loading bars turned off and verbose boot mode turned on? Maybe that might help me to figure out which part is going wrong.

Again, like I said, will go to Ubuntu for another try. Something tells me my Windows drivers (in both Windows versions) are sorta toasted (as they have been ever since I installed Ovi Suite), and maybe that's causing this issue to reflash eMMC. Doesn't explain why the reflash on Fedora failed though.

@dammie: Well, keep on trying mate. On a side note, have you tried restarting your COMPUTER instead? Sometimes that sorts out the driver issues.
