Евгений , if at you 997 versions International, and judging by your profile indeed (the letter x in the name) no problems with installation of the new software downloaded from official site HB, after registration on official HB site, at you will exist. So shows my experiment here in Russia of possession 797 2 years and 1197 this year. New Firmware can be downloaded on this site too.
Here in Russia sell cracked domestic models HB with Russian Firmware much more cheaply, but at updating new Fitmware Russian language is absent.
