Lost "Phone code" problem on a Sagem my-X5

[OperationNT]

Hello everybody,

I changed mobile phone after using a Sagem my-X5 (first generation) during 8 years with the same SIM card. I want to give my old Sagem to someone (so another SIM card will be used). Unfortunatly, when I put the other SIM car, the phone reminds me that I changed its "phone code" but I completly lost it.

After a few researches on the web, it appears that the only way to remove this code is to connect the phone to a computer and edit its EEPROM. To connect phone, I must use a COM port cable. But I cannot find on Internet : I only find USB cables. I find also a driver which should make the OS beleive that the USB cable is a COM port cable. Do you think this method is valid ?

After the phone is plugged to the computer, I must modify the EEPROM. For those modifications, I see that a lot of softwares can make it. Unfortunatly, I cannot find (for free) "automatic and user friendly" software (I particularly think about "Sagem Code Reader" that I cannot find for free).

On this formu, I see another solution by using "Astu" and Sagem Doctor" (I can find those softwares). This solution seems to be a direct edition of the phone EEPROM but I want to be sure when I make it (because I scare that if I make one mistake, I will not be able to boot my phone again). This solution is explained for a Sagem my-X5-2 : the field 100 value must be changed to 00 00 FF FF and the field 102 value must be changed to 00 00 00 00.

Do you know if the Sagem my-X5 (first generation) has the same EEPROM mapping as a Sagem my-X5-2 (to avoid my phone memory corruption) ? If not, do you know what field I should modify ?

Do you know a more simple solution to my "phone code" problem ?

Thanks for your answers.
