but still contact service is still blinking.
what to do.

what equipment do i need for this?.
please help me

I take it you have checked IMEI to make sure that is right?, if not then try software upgrade, if still not working then i guess you still have hardware problem.

Try changing the COBBA and reconstructing data with eeprom tools, it should work 100%

thanq you , i'll try now

If it doesn't work, the connection between COBBA and MAD is probably faulty, but that is improbable in a 9210.

I think that your battery might be low

Try charging it externally, or powering the phone manually with, for example, griffin.
Again I recommend you to change the COBBA, that is your problem!

it is showing insert sim.
after inserting sim it is showing contact service

farrell · 04-29-2003, 12:21

Problem is still the COBBA... did you change it???
If so, it looks like your MAD-COBBA connection is faulty

In which case, there is nothing you can do.

(battery is full.)

How about you measure that Vcobba first ?
make sure CCONT has supply to COBBA
then see what happen !

REFLOW WILL NOT HELP !
