I have been using gingerbread and ICS roms like for like 3 years now and decided to upgrade to KitKat or JB. After flashing the rom I am stuck on boot screen and nothing happens(I made correct sizes of system partitions). I have tryed using both only NAND and DataonEXT but on both I got stuck on no matter if it is JB or Kitkat Rom.
I am using 32GB 4 Class SD card, could it be the reason that my card's speed is too slow?
Or are there any solutions to this problem?
