found eu1 main and generated patch - it was the same number as the above.
so catalin24 was right, i need eu2 patch (filed called K750_R1CA021_FS_EUROPE_2_RED49, but i cant download yet and make the patch).

if this isnt the reason: how can i reflash with setool2 - what file to restore: the gdfs.....bin or the read....bin?
