as i can no longer use my k850i without paying for another flash/debrand, which i just can not justify.. i am left with my W850i


however i am trying to to use my phone explorer to transfer the restore backup of my k850 txts onto the w850

but it says


messages could not be restored
free slots: 980 - at least 1060 free slots are required!




is there a way to fix this?
