Despertar v6 customisation?

Heya ppls,
I am on 3.90m33 at the moment and I'm wondering if the new Despertar v6 gives you the option to boot into 3.90m33 from 4.01m33, and what other firmware there are. Or if I can customise the firmware options somehow that I can access on boot.

Hopefully that makes sense.

Do I necessarily need a Time Machine'd battery as I, at the moment use the Boosters sleepfix ipl that is with UPMS. How would I go about all this?

Thanks!

@ Lotness:

you can add DC6 to UPMS by choosing a different button (ex. UP button)

if you want to load UPMS your normally hold Ltrigger when you add DC6 and choose UP button

when hold UP and then insert your pandora battery it will load DC6

I managed to discover that with some experimentation. Duh.. stupid me. It's really weird having all these different menus all over the place. At least it all seems to work fine, I can switch from 4.01m33-2 to 3.90m33 any time. Really nice. It'd be nice if I could add despertar v6 to the left button boot menu though, have it listed in there like v5,v4, and v3 are.

I imagine someone has already done that though. Thanks for the help silver_surfer
