Exactly Loly.
You've left the original ldr.bin in the Garmin pack 0972 folder although i don't think it'll make any difference because he's already said his nuvi won't flash from sd directly anyway. In my experiments with the bricked 1390 i removed it before using the modded boot bin RGN flash to execute rrgn, copy and del commands. If he can't write back to sd using kunix's method then he probably won't be able to use ergn, del etc commands either and if so neither his data or the unit will be recoverable i think unless you or kunix have other things to try.
