I want to unlock my 6230i memory card but I don't no how?
I am giving you the way to open it and I hope it will be workable. Take any efile manager like SELEQ 1.65 and then open SELEQ 1.65 and go to Root C, there you will find an option and write MMCSTORE and then press OK. Now send this file to your computer via bluetooth. Now you have to rewrite file from MMCSTORE to MMCSTORE.TXT. After the file conversion open the text and get your password. I hope you can do it now!
