I'm a huge stupid
After succesuflly update my N54L to 6.0 and have all in place (I created a new USB key and reserved my old one) , I just wanted to know what would happen if I boot again with the old USB with old boot (The new one if extremely spartan and they do not show progress or anything)
The booting process showed some missing files and several "updating files bla bla bla ...."
Now I can't access to mi N54L
Synology assistan find it, but cant open web or anything.
Of course I switched again the old USB key with the new one with new loader (created in the update process), but it seems something has changed in my hard disks, and i cant login to xpenology (SSH o WEB, no matter what).
Then I tried to change option in boot to Force Install o Reinstall, but the only option that shows my N54L in synology assistant is the AMD option at the boot
HELP !!!
