can anybody help please!!!!
Assuming you are talking about Electrum on your phone. If you have the 12 word seed backup for your wallet, you can just delete the app data and then restart Electrum and it will let you setup the wallet again.
To delete the App Data: This can be slightly different on different versions of Android, but there should be an option somewhere like (Android Settings -> Applications -> Electrum -> Storage). You can then click the "Clear Cache" and "Clear Data" buttons...
Once you've cleared the App Data, it should allow you to recreate your wallet by restoring from the seed and you can setup a new PIN
