My friend gave me this phone model is z818L I cant get it to go past this blue welcome screen how do I reset ot fix this problem

Try shutting it off or taking the sim card off

OK U GOT TROJAN VIRUS AND U NEED TO REMOVE IT WITH BCD

The below steps will resolve many small issues.1.Power off the phone.
2.Press and hold "Vol+", "Menu", and "Power" key until the phone goes to recovery mode.
3.Use "Vol+" and "Vol-" to move the cursor up and down.
4.Move cursor to "wipe data/factory reset", press "Back" key to select it.
5.Now move cursor down to "Yes - delete all user data" and press "Back" to select it.
6.The data will be erased.
7.The cursor will be on "reboot system now" at the end, so just press "Back" key to reboot the phone normally.
WARNING: All user data will be completely cleared; the phone will be in a factory reset status.So before you reset backup data first!! gud luck!!

Dont kno if "Impression" is similar to "Omnia" but 'REMOTE SCREEN ALIGNMENT' program installed on PC skips 'align screen' on your phone. Also "welcome.not" (made in notepad) & pasted into your root files. A REGISTRY EDITOR will allow you to input the touchscreen configuration numbers manually. Of course, none of these will be much good if you dont have 'Windows" phone or cant access your Registry!!

If all this fails, ASK 'XDA DEVELOPERS', or 'MoDaCo'.
