No why do you think that ?

I didnt read the above post if thats why ? I just need my phone unlocking, the title of this forum is 'Free Unlock for Egold Lite based LG phones (KP100, GB102 etc.)' so please could you help by telling me what infomation i need to give for you to unlock my LG KP100
 
I bought a PL2303 cable. The result was the same as with the RS232 port - no response.

It seems the people having the most success are either using boxes or modified usb flashing cables.
 
Ok I've downloaded and burned Ubuntu 9.10 LiveCD, created a ramdisk and installed pyserial. It seems that my USB to RS232 Serial Adapter is given the port "/dev/ttyS0"..

Unfortunately I get the same problem!

It must be the cable? I should have a replacement cable soon and then I'll post my results.

Thank you again for the help!
 
the existence of a serial chip inside a GSM box doesn't automatically mean that the cables are connected to it. I guess that the serial interface is for some microcontroller inside the box which also acts as a dongle and signal buffer.
 
guyjim, if I recall correctly, the port is usually '/dev/ttyUSB0' on Linux systems - but if you are certain that you did everything right, then indeed everything is pointing towards the cable as the cause of failure
 
Well that would make sense however I have just swapped the TX and RX connections and it has made no difference everything is still the same..
 
I have LG GB102, provided by O2.

Is there any software to find SIM lock code?
- just need input IMEI
- without cable or another connection to my LG
- the output is the code to unlock my LG GB102

Whoever who has this software, please share to me...

Thanks a lot.
 
Please I need your help, tell me how do I use this soft and if you need to install Python, excuse my English, I speak Spanish, greetings from Cuba.
 
well, you can easily check your data cable by opening the port with hyperterminal (115200 8n1) while the phone is turned on and its display is illuminated: if it is ok, it responds to 'AT' with 'OK'.
 
I have kp170 that I would like to try to unlock it since with hwk it is not posiblle.
-for now I try with ufs as com port ,cant connect
-tryed with max232 interface ,cant connect
-used ke500 cable from ufs

now I whant to try with directly soldering wires on board but not shure what is corectly pin out
please mark rx,tx
thanks

Go to the Menu->Settings->Security->SIM Lock Code->Network Unlock Code
Enter the code given above.

done.
 
it might also be an issue with the driver or some other trivial error. you might test your pl2303 by just shortening tx and rx and seeing if the characters you enter in hyperterminal is echoed.
 
the unlocking code is most likely random. there have been marks on the soldering pads on both the phones I've tested the unlocker with, suggesting that after production, the board has been put onto a "bed of nails" and locked via RS232 (TTL). There are basic commands AT%IMEI, AT%SLUC (sim lock unlock code) and AT%SLEN (sim lock enable) which can be exploited for this very easily. The unlock codes can be chosen arbitrarily, and implementing a database which links randomly generated unlock codes to the IMEI is trivial. but then again, the service provider might get the stupid idea to use a deterministic algorithm which generates the unlock code from the IMEI - to find out whether this is true, you'd require a rather large number of IMEI-unlock code combinations and some patience.

soldering three wires for txd, rxd, gnd onto the cell phone's board or even using a plain data cable (KE500) shouldn't keep anyone technically savvy from unlocking the phone.

that being said, it's astonishing how resiliant the phone vendors are to use secure means of protection. there are mass production systems which haven't been hacked even though many have tried (e.g. PS3). those shiny overpriced boxes can't do s.. against consequent code signing and strict use of asymmetric cryptography (RSA/ECC) for security functionalities.
 
Ok, I uninstalled the driver, I was using the one that came on a CD with the USB to Serial RS232 adapter (brand: GMTEK). I have installed the latest driver from the prolific website. Seems to be installed OK.. device manager shows as working.

I have then tried the unlock script but I still have the same problem..

For some reason HyperTerminal seems very buggy/laggy. I have connected the TX and RX together and whatever I type in using PuTTY is echoed so that seems to be working OK.

I have then connected RX and RX back up as they were originally (before you suggested they were the wrong way around) and I still have the same problem..

I'm really stuck here thank you for your help so far.
