Hi kokst,

 

Welcome to the Community Forums.

 

Do you recall the version of the older BIOS that you want to rollback into?

 

Update us soon as convenient.

 

Regards

Hi kokst,

 

Greetings.

 

You can try this one for BIOS version 6jcn31ww.

 

Just follow the guidelines in BIOS installation and enable BIOS rollback option initially.

 

Regards

Hi kokst,

 

You cannot do it as battery capacity is one of the safety net that buffers BIOS update from bricking the board during update.

 

Modding the BIOS likewise is not encouraged due to the same danger of bricking it.
