update the bios and no boot

5 posts in this topic

Hello and Happy New Year.


I'm not really a noob hack because it's been several years and some configurations are past my hands.


For the first time, I have a problem I can not solve.


My worries began there a few days. At the home screen chameleon, my keyboard worked randomly. Sometimes yes, sometimes no ... I updated chameleon even cares ...


And I am the most important error. I flash my bios. (3xxx)

And my boot does not work at all ...


The boot stops here




I can not seem to downgrade my bios.


I hope someone can help me because am desperate ...


Thank you in advance.
