NO! Dont flash your phone.<br />If your phone loose network when you are using it with communication soft, problem is in cable. Its because your unlock cable works with 5 volts, but new Siemens phones use 3V logic. You just need to add 3V zener diodes to your cable.

x25/x35 pinout:<br />top of phone<br />1----------12<br />1-GND<br />5-Tx<br />6-Rx

add diodes this way:<br />(anode)(pin 1)--&gt;|--(pin 5)(cathode)<br />(anode)(pin 1)--&gt;|--(pin 6)(cathode)

Diablo22, you know nothing about it and i am crazy ?!? <img src="eek.gif" border="0"> C/S25 and older Siemens phones (S6,S8,etc) use 5V logic and C/M/S35 use 3V logic. This is the reason why X35 phones loose network when connected on 5V cable and you are using them with communication softs like S35expl, SX35, etc. Normal 5V cable works good for flashing and unlocking X35 phones and loosing of network when using communication soft is only problem. Understand ?
