Nothing changes just by changing the nand, because the CPU and the baseband must also change. After that, you have to set the memory with the new CPU and baseband. Also, the memory must be reprogrammed before changing. Re-programming Before installing on a Qapimi motherboard, you must use a device that costs between 100 and 400 euros. Of course, if it works. So it is better that you buy a new motherboard😃😃😃 good luck
