3310 interesting FLASH IC


Hi,
i have one 3310 with flash problem...
Phone can be flashed, but after flashing in flash ic is only trash.
I already tried to change flash ic, ccont, RAM....
interesting is that if i send only small data(for ex. 65KB) in flash ic and then stop flashing, it is ok! But if i leave flashing till the end it will corrupt these data!

Any Idea?

Platy

After flash then ur flash IC become a defective flash IC?
How can u know data in flash IC were corrupted. After U flash the flash file, read it back and then compare the files or what ?

maybe .........

maybe not only flash rom occupies the DATA bus , ( maybe RAM at same time) this can corrupt flash data ( and can corrupt even flash IC ) , for me was such case in 3410 .....

if i flash only small data and then stop flashing in phone it is ok! i can read it back correctly!
but if i won`t stop flashing and wait till the end of flashing whole flash then data would be corrupted - if i read it back it is corrupted!
I already tried to change RAM...

Or change the flash IC with one that is programmed with good stuff (from a working 3310 that can be flashed correctly) .
