Forgot the security code from the Nokia phone, what should I do?
You need to reset all settings by removing the battery from the phone (this is what keeps your password quot; afloat "). You need to completely disassemble the phone (to have access to the printed circuit board), find the tiny battery on the board itself, remove it, and quot; shortquot; contacts of the battery panel for a few seconds (to discharge the capacitor, which is soldered parallel to the battery. After that, insert the battery in place and assemble the phone.
The fact is that the code just will not work off. You have to do a reset to the factory settings. From the phone, go off and return to the state as it was in the store.
To reset, type Dial * # 7780 #. After that enter standard factory code 12345. I hope this helps you. Otherwise, the road to the service center.
For such an operation as unlocking an old phone, you will have to go to a service workshop and there the masters will disassemble and unlock the phone. Independently, without knowledge and special tools, you can hardly unlock this phone.
