cs8210

[rey]

hi......

i got a 8210 with contact service displaying when switched on.

checked using noktool, cobba id displays as zeros only .
does this mean the cobba chip is bad and needs replacement ?
is this a simple procedure or better to send it to a proper service centre?

appreciate ur help , tq .

i got this when i didnt flash mine properly

try reflashing it with the latest version and update faid....

should work if its software failure!

Download eeprom tools,
then open it up, connect your phone, turn it on.
Then click on test in eeprom tools this will then tell you the reason for the 'contact service'

Most of the time it is a checksum error, which can be solved with a reflash!

If it says eeprom checksum error just reset the IMEI and that will solve the problem!

hi guys,

thanks for your replies . will try as advised & get back to u !!

i did as danwood suggested ..........eeprom tools test says cobba parallel failed .

so i guess this requires a cobba ic replacement right ?
from what i've read so far , i'll need some special soldering & heat gun equipment which i dont have .
guess this phone'll be dead for awhile .

anyway thanks a lot guys!!
