I was messing about with my phone the other day when I discovered what seems to be a secret menu. if go onto your menu and press a number it goes to a certain sub-menu right? Go to the last sub-menu and record what number it is e.g 13. Then go onto your menu and select the number 1 above the last menu e.g 14. It will say shortcut not available. Now if you go to the number 2 above the last menu it will say shortcut invalid, Maybe this means that 14 is a menu, but you arent allowed to goto it, anyone have any ideas?

. What phone are you using, if its a DCT3 then it's the netmonitor or simservices menu you are hitting. This also happens with DCT4 phones, so a lot of people reckon that netmonitor is also on these phones but no-one has cracked it yet, more is the pity.

mostly dct 4, the 3300, 3510i but also the 3310

u may flash the phone again, then fix.

Thanks a lot

It's no secret menu. Menu 14 is for provider special Menu. So in germany at T-D1 ist's called T-D1 Special.

edit you

the menu of 14? i think is close the net monitor on phone within sim card by press the command key *144#,after that phone cant find the phonebook menu and last dial no .pls reset factory setting by manual..
pls post the result
sorry for bad english.... :(

Same thing on my nokia 6230!
menu = 10: sms - services
menu = 11: "Shortcut not available"
menu >=12: "Invalid shortcut"

As far as i know the Net Monitor ("Field Test Display") can be activated by a firmware update. Question is if it is actually already implemented and only a bit has to be switched or something alike. That's how it worked woth the old 6150 etc.

I'm looking for a solution.
