L710 sprint/boost odd request

Hi,

So I have a bit of an odd request. I have tried everything that I can think of to install any version of lollipop both versions 5.0.1 and 5.1 roms for L710 sprint /boost and nothing works. Only thing works is Kitkat

So I humbly request if anyone running 5.0.1 or 5.1 on sprint s3 can dump a twrp backup of there phone minus personal critical data and apps. I can possibly try to restore from backup and see if it can work. Don't matter what version it is as long it's for s3 sprint and it's lollipop and is a twrp backup file that would be super awesome and appreciative

Thanks for at least hearing me out
