remember you only have 5 tries, you may have hardlocked your phone already. #pw+735 550 750 347 760+7#
“Cannot undo restriction” or “Not allowed” means. After you have made 5 attempts or even 3 attempts on newer phones and failed, the phone displays that message, meaning that the phone is "hard locked." At this point, you will still be able to use the phone with the original provider, but you will not be able to unlock it by codes. You will need to take or send it to a professional for direct unlocking service.
OK MATE cheers ive also got another 6230 locked on orange imei number 355038002668417 need openin to o2 again cheers
