I'm hoping you guys can help. i bought a used DX off ebay that already has .621 on it ive downloaded and burned the cd and have tried to root my dx several times but the first thing it says is rm failed for /data/preinstall_md5/magic md5/magic.md5. No such file or directory. and then proceeds thru the rest of the rooting process saying the installation everything else has failed. Any thoughts???
