Are the steps how to hard reset the Nokia 8110 4G similar as shown under "Is the FAQ/How do I hard reset my smartphone and completely restore it to the original factory settings? by Moderator Anna" or are they different since the Nokia 8110 4G is not a smartphone but a feature phone?
Under "Settings", "Device" and "Device Info" there is a "Reset Phone" option. Is that what you are looking for, or some 'magic-key-combo' like the good old days?
I was hoping for the 'magic-key-combo' like the good old days because I saw on YouTube, that could be done on the Jio Phone.
There is a combo described here
but of course this requires the device to be functional enough to go to phone number entry.
1) Remove battery
2) Hold scroll, and keep it pressed
3) Insert battery
4) Press power (long)
(and release scroll)
A menu appears, navigate with arrows up/down, use power key to select. :)
Tried to answer, but it disappeared, here a shorter version:
Hold the Scroll key while inserting the battery, and press Power to turn on. A menu appears, navigate with up&down, use Power (not scroll) to select item.
