First of all I would like to apologize for creating a new thread for this question. I asked the same question at [HELP THREAD] Ask ANY Question. Noob Friendly. in September last year.
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"
=============== Memory Detection Report ===============
Size = 0x00020000 (128KB)
Type = DRAM

EMMC_PART_GP3 Size = 0x0000000000000000(0MB)

EMMC_PART_USER Size = 0x00000000E9000000(3728MB)
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.
I really appreciate any help you can provide.
