Nokia 7110 - "Contact Service"- problem - GSM-Forum

nicos · 10-31-2001, 09:31

Hello to all, Nokia 7110 was felt (dropped) on the floor. After that it shows "contact service". Anybody sugestions what is the problem? Can something like that cause errors in software of the phone. Is it smart to try flash it (full flash - upgrade)? Thank you Regards, nicos

Yes. Rehot cobba & ccount.

Just CCONT faulty, not COBBA. Reball or change CCONT!

I'd try to flash it first before I even open the phone.

If cant be solved by flash, then go ahead and open it up.
