Thanks for your answer.
I read somewhere - don't remember where unfortunately, that SD Cards above 32GB (SDXC?) needs to be formated in FAT32. Is that what you mean? I've heard too, that some custom ROMs requires some other SD Card partition - extSD or something. Then when I'll format new card in FAT32 is it still possible to flash custom ROMs and will they handle this card?
Thanks in advance for your answer
