Hi Popsel
Thanks for sharing your experience.
In my case, I think many of us would appreciate if you let us know how to enter in service mode, even considering the risks.
Obviously, the eventual risks involved must be commented in the post, but there is various post in this forum with information that, if applied with no care, could bring serious risks to the hardware (like some suggestions about how to reduce the key bed noise.......).
Also load ZAL files shared here are a risk of loss personal work in some cases!
Cheers
