Problem in Installing Rockbox

[Starkilla]

I wanted to ad that when I try the manual installation using Rockbox Utility I get the message: "It seems your bootloader is already up to date. Do really want to install it?" When I press Ignore he installs all files in the .rockbox directory but no update happens when I plug in the charger.
When I press "ok" it says: "unsupportet install method". When I stop the Rockbox Utility it stays as active task which I have to stop manually using the task manager.
It seems the utility is not able to update the bootloader.
Does this help?

Wow, I managed to upgrade to 2.11-e. I plugged in the old sub pack which I still have from my m3 and plugged in the charger.

Following that I tried the Rockbox Utility again but again getting the "It seems your bootloader is already up to date. Do really want to install it?" error again.
I then copied the rockbox bootloader manually in the FIRMWARE folder and again pluged the sub pack and charger in and the Rockbox is now working fine on my M5 :-).
