my nephew has a unmodified 2DS, currently the motherboard/charging port is broken and the battery has to be charged through other methods and he is getting a new 2DS to system transfer to, now my question is with the new firmware (11.3.0-36U) may block some entry points for downgrade, if i install a CFW on his current 2DS (11.2.0-35U) will it transfer to the new one? or if i install a CFW on the new 2DS will transferring his old system mess with the CFW? i know they make you update the system to do the transfer and ive searched but havent found a clear answer
