[skengy]

Hey guys,

I have a BMW 6 series 645ci 2004 - E63,

I done the famous restart I-drive by holding the down the volume and ejects buttons and is in a continuous loop.

I diagnosed it with INPA and got a software error thats cause the idrive to keep rebooting.

My question is how would i go around around reinstalling or flashing my IDrive CCC ?

or what are the steps ?

I can do code so i can do the difficult task just need some guidance on software and files etc 

Currently have 

INPA and K + DCAN Cable. 

Please help 

Thanks
