RF tables: look in my freecalypso-reveng repository, se_k200i directory - the rf_XXX.c files you'll find there are extracts from original fw. Basically you would need to copy gta0x/rf_tables.c, keep the levels tables unchanged (SE fw left them unchanged from TI's version too, as you can see in my rf_XXX.c extracts), but replace all ramps with those from se_k200i/rf_XXX.c files. However, what APC offset is used by the original fw is the big unknown, and if it's wrong, all levels will off despite reading calibration records - this part is always a bummer.

AFC params: use "tiffs $flashdump 256x13 decode afcparams" to look at factory numbers on a few units, then use my little osmo2psi hack in freecalypso-reveng to find an AFC slope number in your style that is approximately close.
