Nokia 8810 "Contact Service", can't solved by re-solder EEprom, Flash & Ram.
 

As topic, any ideas?? Also, I discover that the phonce can't communicate with Wintelsa.

Hi ,

I tried that is MAD 2 failure or dry joints.
Because MBUS is link to MAD 2 & phone
can't communicate is MAD 2 not operate.

Sorry about my badly english

Regards

Nevermind, thanks for your info!! BTW, my english is not good enough thru. :)

Reflow mad. Take of the nozzle from your hot air gun and reflow mad for 30 secs. Using 300 C and 3.5-4 setting on ****er using Quick 850+.

Thanks mate....

It connect now.... But still can't solve the "Contact Service" problem.... I think that the EEProm content is corrupt.

Do you have the full flash / EEprom files for Rolis???

Try connecting an mbus cable and read test on wintesla or eprom tools for what the reason is for contact service. Yes you might have to reflow eprom or ram too. Good luck.

Thanks for your kindly reply....

The version of Wintelsa that I use now is V5.38, the DDL for 8810 is something wrong with it.

If possible, would you kindly pls telling me where could I download the Wintelsa w/ all cracked DDLs (Included 8810) ??

Also, PCLocal.....

Thanks a lots!!

Hi

Ken-mkII: If you already connected mbus cable, try reading it with Nokia Tool and look if data are correct. I mean SP lock, IMEI data.

Or use b-phreaks eprom tools, click on test and it will tell you the reason for contact service. If it says eprom tune checksum or interface... just flash eprom area with a copy of another phone's eprom area. change IMEI, recalc FAID..
