I see the trace you attached is still using "all" for one of the
networks:

<<<<<<   translated = { [0] = '[ mcc = '228' mnc = '3'
radio_access_technology = 'all' ] ' [1] = '[ mcc = '228' mnc = '1'
radio_access_technology = 'utran' ] '}

Did it still return UimUninitialized when you did it without "all"?
