for fdl 1 &2 , you'll need to search for compatible ones. a good place to look would be from the pac file of a phone thats similar to yours. 
as for the nv items, it would help to know how backup was done

Hello there..



Please do you have a backup of k touch t621 phone?


I can't access the launcher and there is no way of flashing anything through recovery mode.

Thank you
