6210 security code

Hi
I currently have an 6210. years ago, I've changed my security code. A few weeks ago I changed from operator (so ofcourse that includes a new sim card). Result, every time I put my new sim card into my phone he asks the security code. Now I've tried everything I could think of but I still can't find my code. If I put my old sim card into my phone, he doesn't ask shit anymore ;) but when I'm trying to reset the phone to the factory settings tatataaaa he asks the security code again.

My question is, isn't there a general code to reset your security code to 12345???

Thanx for any help

Hi!
You need Noktool by Rolis v1.9 /it is in download section/ and f/Mbus cable. This will do the job.

It wil not reset the 6210 code that because the 62XX/7110 use a different method of storing the sec code. you need to flash a virgin eeprom to the phone to fix your problem duplos.
