Probably nothing to do with Far Manager (whatever this is) but I tried to stick to this thread: k610i problem patch. And after these last answers I have noticed there was another one, regarding W660. I thought about it earlier, before registering here but saw some problems people were describing (like solved illumination, though some posts were denying it, that it is not perfect). And somehow I decided to do it after you gave me on the plate these files names. So I did not flash missing K610i_CDA102497_13_R19A_T-Mobile_DE_Germany, but went straight into
W660_R8BB001_MAIN_GENERIC_FY_RED52
W660_R8BB001_FS_EUROPE_3_RED52 and custom file
HB1-06_Gen_CDA102568_12_R8A_GENERIC_EUROPE_3

and
Converting K610/K618/V630, Z610 and K530 to W660. Full Guide!.
So now this thread transforms to W660.
I have followed those instructions without problems (I did skip Sony Ericsson Update Service).
My telephone though is network locked now (Service Info>SIM lock).Other padlocks are open. I can use it with 3 (as it was originally)
I can see, K610_Pack_1.zip file contains few others patches (next to illumination one), one of them W660 R8BB001 Unlock.vkp
Will this unlock network padlock?
Also, do you have some comments, if I had purchased some music, i.e. dcf files on my k610i. It seems I cannot play them on w660i. Perhaps I need to re-download them on this 'new' model.
