have u tried ur digi prepaid on other phones?

if not mistaken can straight flash it without wipe
for more info just ask at the thread
GC is quite active
try other usb port ? 
just go change new simcard lar, you already create the thread to ask this answer

off course is same, both also micro sim
some gold part is big, some is smaller
just use only, no need care, just use the one digi give you =_=
go general post
*got malaysia thread at there, go there spam

must go service center
nothing related with the gold part
and if you want to request, why not, pay money only
since you change micro sim also same = your phone problem already
since you also say work for other phone

1. Yes..warranty for one full year. (Keep your receipt)
2. Claim warranty and service..Free

Better go straight to service centre..much quicker

If not, I think 32gb will be more than enough lol.
