So, it seems i only post bugs on softwares for our beloved E398/E1, but I i'he found another yesterday and i think good to post here..
Well, going to the whole story..
Yesterday, when I was applying the RGF on my e398 and putting on it all the things that makes my phone fits in my taste, i've notted that after all made the ring sound couldn't be changed anymore. Well... it could be changed, but when i received some call, it rang with another ringtone, the default one.
After find out a lot, i've discovered that it happened when i restored my personal data with Flash&Backup 3.0.6. It happened just when I restored ALL data (phonebook, datebook, messages and alarm clock). After, I've tried restore only messages that were the most important thing for me and bug didn't happen anymore. I think it happen due to restore of the alarm clock. I'm not sure about this couse i didn't have time to try with other combinations..
