my freind i have two ways to do this one is to refly the main board

tunjay-gsm · 11-22-2006, 13:09

or your second option is to reball the uem chip

thanks yours respectfully

sandeep_singh · 11-22-2006, 13:29

this problem not from uem.

i can reflow.. but reball is much more successful

but i wish i could 'refly' cos then id be the best phone repairer ever ... haha

second thoughts, id be happy if i knew what refly even is?

Hi brothers.

its my tested and its sw problem 100%.

(1) 1st full erase the phone.

(2) 2nd flash with 3.94 version only mcu ppm.

then check your phone without pm .

your phone will be ok then write pm.

i trust to me.

@gsmstroong : 100% sw prob? ha-ha...
if you solved it, it doesnt mean you have 100% solution.
100% solution is:
1) sw methods (what you say - only MCU????? well,
your customer will be VERY glad for it's EMPTY phone!!) .
if does not help -
2) reball ALL bga chips, including CPU+Flash (sandwich).
