i'm trying to update my ipad from ios 3 to ios 4.3.3. I already put my ipad into dfu mode. then i put in to itunes and hit restore. but without tinyumbrella, itunes keep give me error 3194. when i use tinyumbrella to fix recovery, my ipad just turn white screen and then with some codes such like unable to find gBdevlist, fs_mount, greenpoison initialized and etc. With this mode, i get to recover from itunes but each time itunes finish installing the new firmware on my ipad, my ipad just went back to recovery mode again. anyone help please? thanks in advance
