Did you dropped your unit? It happened to me before when I dropped my 8250, it freezes once in a while. I opened the unit and do some "hot air" all over the pcb (printed circuit board). Try first to upgrade your version and if still the same problem occurs, then it's time to do some "hot air". After that, let your board to be cooled enough and then turn "ON" the switch of your unit and you will see the difference. By the way, do you have the equipment?

email me if for more help. [email protected]

most of the problem is MAD 2 dry joint,
just replace will do

[crazyas]

yea i got the exact same problem mine recently began to have the problem more constantly :( ive only got a data cable with a MBUS/FBUS switch on it.. is this enough to flash or fix the fone?

Hi,

I have same problem with my 8250, after reding this thread, I use hair dryer to blow the PCB (blow the cpu MAD2).
No intermittent freezes new....
Thanks angjh :)
:D

[leboneez]

where is the "MAD 2 dry joint"
on the pcb baord

[leboneez]

anyonezzz

[mudchild]

mad2 dont mingle with it. take it to the experts.

[angjh]

for old hardware id of the pwb for nsm-3d module, mad2 was underfill with a special type of glue, we just use normal blower to take it out( becareful, it might damage ur pwb or mad2), clean the glue, reball and then put it back.

[leboneez]

coolz

but were is MAD 2

what do u mean by reball

[crazyas]

heh i tried a blow dryer and my fone works good strong yet for only like few hours hehe. it seems to be having problems on hot days as well :( since i can't find a place to get a flash cable i gotta find a place to get it fixed... unless i can convert my mbus/fbus to a flash cable

[leboneez]

how long are u meant
2 heat it for
with a heat station
