Hi jojojmtk,

 

Greetings.

 

Latest BIOS version may be the only ones available from the support site for the Idealine products so best to call in technical support for their recommended steps.

 

You may also want to look at this discussion as others were able to get older BIOS if you also knew the old version file name. Here I tried to read first the text readme file and replaced the latest BIOS link with 4qcn43ww.txt , then download the zip and replace the end with 4qcn43ww.exe showing version v2.07. Read the readme files first and have the charger connected with batteries charged 80 and up.

 

I have not tried using yet so I suggest you work it with the tech team. The BIOS configuration tab should have BIOS backflash set to enabled too.

 

I hope this helps answer your query.

 

Regards
