A:
that is hardware problem and nothing to do with software. usually it is bad soldered flash chip.
latest mid-range semc phones quality is below zero.
as last resort, you can try to raise voltage on FLASH VPP upto 12v
(for start, try to flash it with dcu60, it also has increased voltage)
but what say to customer if phone works before servicing?
have no idea - think yourself- that is risk that you including in each service cost.
sadly, but such thing can be happened - flash sector can read good, but fails on erase/write.
