Howto flash 2003 to WM6 and possible to downgrade back?

[nEuDy]

Hi @ll..

i have a MDA II from T-Mobile (PH10A).
But before i flash it to WM6 i want to know, if its possible to flash then back to WM2003 with my Shipped Romversion of T-Mobile??
I found nothing about that...

And have i to CID-Unlock the device, before flashing to WM6??? (like the other devices???)

Or can i only flash any WM6 ROM here in Himalaya-Forum (and then hard-reset and format the chip in the bootloadermenu?)

Thanxx 2 @ll

never heard about cid locking or unlocking for himalaya
only thing locked on some himalays are sim

i would asume that whatever actions was don to flash the device to wm6
5 or anything will work just fine flashing it back to 2003
just with a 2003 nbf file rather then a wm5 or 6 nbf file
