Archos 50 Titanium Recovery/Fastboot

Hello,
I have here an Archos 50 that is always booting to the bootloader menu with the 3 options:

• Recovery Mode


• Fastboot Mode


• Normal Boot

The thing is that the selection arrow is always jumping in cycle between options, and the VOL_UP, VOL_DOWN doesn't do anything.
I can't select any option and then it just cycle reboot again...
Already opened the phone to see if the VOL buttons were stuck, but no luck.

Any workaround to select the options?
