It helps if you use the correct charger for your mobile

Ach-6


One eagle-eyed visitor noticed that although I correctly said ACH-6x (10 volt 740 mA) as the correct charger for the 8110 series mobiles on some videos, on one of them I grabbed the wrong charger and said ACP-12x (5.7v 800mA) which of course is the charger for the Nokia 7110. Apologies.

So make sure you use the one on the right and not the left. You can try the one on the left but as the voltage is insufficient it will just beep at you in disgust and do nothing.
