Hi,

 

You are trying to "update" the actual software version with an older one.

It's not a lucky situation.

 

Before trying to dig deeper, did you tried  to do a factory reset on the phone?

Ofcourse, before that, you need to backup your data.

 

Regards.

I tryed...

Factory reset not change radio band. Still I have USA Band.

I think I will can resolve problem:

1. Reset Modem...

2. Unlock BootLoader and manually instal ROM - TWRP.
