1. Insert a non accepted sim, most times it will show "Phone Restricted"
2. Press the UNDO option
3. You should see a box that says enter restriction code.
4. Enter the code given and then press (OK)

 

For some reason it said "Cannot undo restriction" i will be greaateful if u could help me out

Thanks

 

“Can Not 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 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.

 

okey thx a alot

 

how about if i Flash the phone would it make any difference?

 

ohhhh yh and orange sim card works on it but there's no network coverage.. its registered to uk so i think it should work..

If u have any idea how i could jus get the coverage let me know plz

Sorry these are prob stupid questions but i dont know much about Phones..

Thanks
