thank you for tutorial to retrieve fwf file, but i’ve found this easiest way in http://forum.mikrotik.com/t/failure-firmware-upgrade-with-netinstall-and-loading-kernel/159083/1 using 7 zip and navigating to folder etc.
unfortunaly still stuck in jumpint to kernel code.. like MKX said, maybe my flash is unoperable..

Something curious:
when I reboot it from power with backupbooter - routerboot return from 7.16.1 to 6.48.6

so.. last try, routerboot 7.16.1 and netinstall 7.16.1.. still jumping to kernel code..

support is sending some procedures, if any of them works. I will post here..
thanks for help.. at least we discover where to get fwf files easly.
