Like so many people here, i have also forgotten my phone Lock Code. So today i have decided to reset it anyhow and while playing with my phone K850i - A2 phone, db3150, BINGO, i found the way. May be this should work with all platform phones. But still this has to be confirmed by the owner of different platform phones. The solution is- look in your FS in this folder. tpa/preset/default now delete this file- 'security_domain_settings'. That's it. Your Phone Lock Code is reset to 0000.Before deleting you might want to back up that file. Though it is not required. Tested by me.Pls confirm this method by different platform phone users. edit: Just found that by deleting this file, it is not recreated. so there might be some functions which will not be able to use if you delete it. But by activating it, it serves the purpose. asking for passward and all. if you give wrong passward, it will not let you access. Do it at your risk. this means if you forget the passward again, you will not able to retrive it. edit 2 : By flashing the phone this file is recreated and you will have the same passward as you have set after deleting that file. In my opnion, just flash your phone after you use the above mentioned method.
