thats what i did but didnt wrk as netinstall didnt show the RB on it .
i think the issue is in windows7 ii will install winxp on othere PC and give it a tray.
Thanks for your advice
i was using windows 7 x64 when netinstalling
,it working fine,the hardest part is either making your own serial cable or finding the right product for the serial->usb converter which works on windows 7.
do not format the NAND ever !
to upgrade, FTP the packages and reboot. This will keep the license. After you are at RouterOS v4.9, use Netinstall to erase the Frequency Lock.
sorry normis just fellow newbie here trying to help
,strange i was formatting my nand before netinstall and the license seems persist,i felt a bit safe eventough i lost my license because i already backup the license key,is it the right way?.
