Installing OpenWrt on RB2011UiAS-2HnD-IN fails

Is anybody have success on doing sysupgrade for RB2011UiAS-2HnD-IN for recent versions of OpenWRT? I have AR9344 v3 version, tried to build firmware from source and different stable and snapshot versions. Initframs loads well, Gbit ports works, but after sysupgrade router goes to loop reboot. I'm tried also this solution, but no luck.
