I own a Jiayu G3 and one day it suddenly stopped working.
It's possible to access the META mode and therefore I can flash it with a new firmware (for example: G3-20130116-221844 stock rom) with SP Flash Tool. However the phone won't power up. I don't know if I'm doing anything wrong. The flashing seem to be OK, but when I perform a memory test with the same software it gives me an "ERROR: Nand flash was not detected"

I guess there's a chance the problem being a physical one. Although the error message makes me a bit more optimistic and make me think there's an easier "do it yourself" solution.
However, I noticed another thread on this forum: http://www.modaco.co...yu#entry2167782
In reality I most likely have the same problem as him. But do any of you guys/gals have a guess which part that may be faulty? I managed to turn on the phone three times but the screen went black during the boot image.
I really appreciate any help you can provide.
