Ok Catymag,THANK YOU VERY MUCH!
I made it. It write the Region41 fail, I didn`t know that the HWID for 3770 is 1406, but in the log it is written:

nьvi blade Series Software Version 2.70, UID: 384356xxxx, HWID: 384356xxxx
------------------------------------------------------------------------------
Parsing "if_error,rrgn,abort"
Error: invalid command 'if_error'
Error
Parsing "rrgn,41,1:/41-backup.bin"
Success
Parsing "reboot"
Success

And why there is an error in If_error?
