Hi Guys Im goin off my head here folks. I upgraded my kids NCards with 1.45---2.53 supposed latest firmware ( nand_stable 25) menu and on all the games I now get the error Data could not be written. Turn off the power and reinsert the card. Of course when I do this it changes nothing . the games are all listed as before but when trying to load them the same error comes up again. I reformatted and tried running the nand_stable 23. this seemed to run ok but when I turn on again it still says 2.53 in the corner and the error still comes up . PLEASE PLEASE PLEASE Help me someone out there . My kids are drivin me crazy over this. I have reformatted before and after the firmware flash and loaded the appropriate xmenu.dat . I think I am doing something wrong . I want to go back to a firmware rev and menu option that will work again . can someone please point me in the right direction with this. thanks to you all in advance.
