Hi, this is probably a noob question but i couldn't find the topic elsewhere on this forum . I just from stock based rom to 4.4 carbon rom. But when i do i loose all my saved data on internal storage,. luckily i did a backup that i copied to pc, so i could restore my previous system - and wiola - files are back! the same happened after 4.3 rom update. It seems that the newer androids change something, so that the system detects the interneal storage differently. Or is this just my phone? any way to prevent this from happening ----- or would my nest option be to backup and copy everything on my pc and then do a format of sdcard and copy everything back on when doing an update????
