Well. I made it!
It's all start from my desire to have a 5.1.0 firmware. I try it, but got an "error update 007", then i decide to downgrade for 5.0.0 by "simple debrick" method,
and i got a black screen at boot as "main". I rollback to my previously made backups and book runs normally. I try to upgrade firmware again - and i got it!
Looks like after all of my attemps one thing which is changed it was:
dd if=/dev/zero of=/dev/mmcblk0p3 bs=4K
So if you get error 007 on update try this command.
Thanks for all of you!
sorry for my English
