What is the correct value needed?

about the diod
 

the zener diod how much should be same as battery phone 3.5v??

I use N5819 diod from an used :D cordless phone.

Best regards

or use PL 3v5 or DZ 3v5 from electronics store

lol anyway i've tryed to build up the cable but it doesn't work
PS i've used a zener diod 3v

Thanks a lot
 

nice post! you saved my ***:O

Mate , you must keep a "secret".:D

Work also without diod.
The secret is when you change Sim after flash , phone must be ON

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.
