Mate , you must keep a "secret".:D
Work also without diod.
The secret is when you change Sim after flash , phone must be ON
BR
Another secret : Flash Phone with patched firmware. Insert 3 sim card , power On phone, insert code *854#46 (only 890) , phone restart automaticly.
Quickly you must change original 3 Sim card with another sim (phone dont turn off). Done.
Is not a definitiv unlock this one, but is first step. Any time you want to change sim card or Phone turn Off, you must do all from 1 step.

I explice for all the world veiled that the diode and a connection NI4148 it is because the portable boot directly on the software not more bus if one does not put the diode the u890 posts IN LOAD veiled all is well details
