Good Morning to all,
Bserey, the file you want is a RUU yes but the one you have linked is not an offical RUU from Verizon. The reason for this is that verizon has not released the global update yet for the Rezound.... That being said you can still use it as many are already. If you want the offical release here is the link

Eleni, It sounds like your nandroid backups failed. Most likly due to limited space available. This is what I see most of the time when that happens. Unfortunately they are lost. As for your Titianum Backup's it sounds like you might have it over writing the lastest backup Now please do take that as gospel as I do not know your settings but if you check using a file explorer program (like es file explorer) and they are not there then I would have to sermize what i have said as being true.
