So after reading through 8 pages of this entire forum I finally figured out the solution to the second problem only a few number of people, like myself, are having. If you CAN completely get in and out of your phone and access everything but you CAN'T change your alternative password nor delete your previously saved fingerprints due to the fact that to do either of these things you constantly get prompted for your alternative password which your phone then doesn't except. Regardless of if you forgot the password or are putting it in correctly and it's not being accepted there is a relatively easy fix.
Basically, you just go to your Settings and then go to you Application Manager. Once there go to the list that gives you ALL your applications not just your downloaded or SD card ones. From there scroll down until you see an app entitled Fingerprints. Click on this and simply click on Clear Data. After that is done go back to your Fingerprint Scanner and you should be able to finally enter your Fingerprint Manager to delete the preexisting fingerprint registrations and all that jazz. You shouldn't be prompted for any passwords to get into the Fingerprint Manager. If you are, try restarting your phone to make sure the data got deleted properly.
Hope this helps.
I can't take full credit for it because the idea was sparked thanks to usoska's suggestion (post #170) to download Titanium Backup if your phone is rooted.
