Why my 8250 can just only use INTEL flash ic?

[SWAT_Unit]

When i change to SHARP LRS1360 flash ic,
SRAM can't properly erase n write.
Anybody know what's happen,n can explain it.
p.s. :no broken line,flash ic is good,use to other phone can work.

ThX for reply

Check for cold spot solder
try reflowing it again
might work then
if not replace with a new one

Thx crashynot,i try ur solution many time already.
But the result is same,i use intel ic,i flash the phone,
after that read the fls from phone.Than use hex workshop to compare,
it will show match.But when i use any sharp ic,it will show some
place have difference value in sram area.
I think the phone is set something by factory,
so the phone can select the flash ic vendor?
