I have locked myself out of my Samsung Galaxy S5 How can I get my Samsung Galaxy S5 unlocked without having to do a factory reset?  The phone is asking me to enter a back up pin number,  but I don't know what that is. I have tried EVERY password that I thought we set up on this phone but now it says that I only have 1 more try b4 it will factory reset and erase all my info....Please, HELP!!
I think there is a way to remove the lock. While I don't own this particular phone, you can flash Aroma File Manager to the phone by copying a zip file containing the manager to your external SD card. Boot the device into recovery, and then install the package. Go into the system files of the phone. There is a file somewhere called password.key or pattern.key, depending on whether the lock is a pattern or pin/password. Delete it. If the system files are not showing up in Aroma, make sure the device has mounted the system files in options. Reboot, and the lock should be removed.
