C62 cable schematic :

Hi guys,

I made the interface as the schematics, but it doesn´t work. I replaced the 10 uF capacitors with .1 uF 50v, as shown on max232 datasheet, and like others cables I made that worked. The rest is exactly as the schematic.
I fed with 12v from external power suply, with and without the resistor. Does anyone has any tip/hint?

thnx

hi.

i found out that was my mistake. one of the capacitors were inverted. I fixed it, and gone loggin´. Log reader says:

Power On
Phone Ok
Boot...
Error W:3 R:0

and then it stopped responding (Windows XP). The handset doesn´t work animore!! It´s dead!! How the f*** could it get fixed, if there´s a way?

[celiovaz]

it had one last breath... it said:

power on
phone ok
error w:9 r:1
error w:3 r:0
failed!


any hints? Zulea, can you say something?

there is big confuson about this cable...i am sure others have had good experience with this schematic....but i have had no success....

btw, there is excellent documentation for Max232 (TTL-CMOS/RS232 converter) on www.maxim-ic.com and thats the heart of the whole exercise...in that only the values of capacitors are different but they are for blocking/bypassing any ac component in the circuit...so a value of 1 micro or 10 micro doesnt matter really...still its not working...

any spark of genius anyone has ...most welcom !!!!

You change as this:

1,2 to GND
9 to external +5V

Have tested, all are right.

dear plz look at this : Siemens C62 unlock - FREE download here

Trick is - u plug in the cable after giving command in logger. IF phone turns on, off it. Do not remove cable, just press power ON button. If this doesnt work - do a reverse procedure.

ANd to run log decrypter comfortably on your PC, i suggest to use a clean win98 installation. Any antivirus software or debugger FREE environment is preferred.

Try with Windows 98, for me logger also won't work under Windows XP (MAX232 interface)

@ all those who replyed

Thnx ppl, but I managed to unlock another phone with this solution. It´s already working. But my real problem now is: Dead c62 while unlocking. I discovered that the power suply I was using wasn´t stable. I guess it was the problem. The headset doesn´t turn on anymore, or give any sign of beeing alive. But it charges the battery, although it does not appear on display. Is there any way to re-live the phone? Any attempt is valid, as the device is already dead...

The solution that now works, is to feed the cable with a 9v battery. More safe, and u won´t kill the phone, like I did.

Can this problematic C62 be unlocked using Siemens Clip (GTCL) ?
