i erased my uboot in the process of upgrading it and then the power went off before i could rewrite the new one... now it won't boot up again, so i tried that: http://plugcomputer.org/plugwiki/index.php/Reflashing_images_on_the_GuruPlug#Flashing_U-Boot_on_Bricked_Plug

unfortunately i seem not to be able to get it done

sudo ./runme.sh openocd/uboot.bin
cp: „openocd/uboot.bin“ und „openocd/uboot.bin“ sind die gleiche Datei
 ****     Preparing environment variables file ...
 ****   Burning uboot and environment variables ... This will take few minutes ...

Runtime error, file "./openocd/./board/guruplug.cfg", line 24:

i read that the timing is important so i tried plugging the power in at about a hundred different timings, but it's not really working... any tips?
