I just downloaded the "bootloader.iriver" from the iriver flashing page to my H120, and opened it with the iriver_boot plugin. it asked me whether I was sure about this, and when I pressed play it wrote "success!". Now when I turn on the player it says "version: 060811 -2251" and loads rockbox.
However, if I press the Rec button when turning on the player, it says "loading original firmware" and hangs.
P.S. Wasn't this supposed to make rockbox boot faster? It takes the same 6-7 seconds it did before this whole thing...
